`DECLARATION OF DAVID ETCHELLS
`
`
`IPR2020-00597
`Apple EX1007 Page 1
`
`

`

`I, David Etchells, declare as follows:
`
`1. My name is David Etchells. I am over the age of eighteen (18) and
`
`otherwise competent to make this declaration. The statements made in this
`
`declaration are to the best of my knowledge and recollection. I have personal
`
`knowledge of the facts set forth in this Declaration, and, for facts stated on
`
`information and belief, I have been provided with information by a person having
`
`personal knowledge of such facts. If called as a witness, I could and would testify
`
`competently under oath to the facts stated in this declaration. I am being paid at my
`
`standard hourly rate of $250.00 as a non-technical witness.
`
`2.
`
`I am the Founder, Publisher, and Editor in Chief of Imaging Resource,
`
`a Photography News and Review website. I launched the Imaging Resource website
`
`on April 1, 1998, to provide photographers with unbiased, detailed information on
`
`digital cameras, particularly actual sample photos shot under carefully-controlled
`
`conditions. In addition to my managerial role, I have authored numerous product
`
`reviews and articles published by Imaging Resource.
`
`3.
`
`I have been a photographer for all my life, starting photography in 1970,
`
`maintaining a dark room for personal use while earning a BSEE and MSEE degree
`
`from UCLA with a specialization in semiconductor physics.
`
`4.
`
`Prior to founding Imaging Resource, I worked in the California
`
`aerospace industry and delved deeply into image processing architectures while
`
`2
`
`IPR2020-00597
`Apple EX1007 Page 2
`
`

`

`working at the Hughes Research Labs in Malibu, California and was named as an
`
`inventor on three image-processing patents. I also ran a Macintosh-based systems
`
`integrator (Perspect Systems) in LA in the early 1990s. Some of our clients produced
`
`huge volumes of photography for mail-order catalogs, and a study I did for one of
`
`our clients in 1992 on the economics and performance of digital studio cameras
`
`turned into a widely-circulated industry report, recognized in the Seybold Report
`
`and marketed through the Future Image organization.
`
`5.
`
`During my work for Imaging Resource, I wrote a product review for
`
`the Casio QV8000SX digital camera. My review of the QV8000SX digital camera
`
`was first posted on Imaging Resource’s website on January 26, 2000. A copy of this
`
`product review is attached to this Declaration as Appendix A. I downloaded this
`
`product review from the Imaging Resource website approximately January 2020.
`
`6.
`
`In order to begin my product review, I reached out to Casio requesting
`
`the QV8000SX digital camera, and Casio provided me with a QV8000SX digital
`
`camera. An email attached as Appendix B and dated November 1, 1999, confirms
`
`that I had received the QX8000SX digital camera from Casio at least as early as
`
`November 1, 1999. This email (Appendix B) is between a colleague, Mike Pasini,
`
`and me. In the email, I write to Mr. Pasini that we just received the Casio QV-
`
`8000SX:
`
`
`

`
`IPR2020-00597
`Apple EX1007 Page 3
`
`

`

`(Appendix B).
`
`
`
`7.
`
`I received the Casio QV8000SX digital camera in its original
`
`packaging. Included in the packaging, along with the camera itself, was a paper copy
`
`of a user manual, which is still in my possession. A photocopy of this paper user
`
`manual is attached to this declaration as Appendix C. Photos of the Casio
`
`QV8000SX camera, user manual, and original packaging, which I currently have in
`
`my possession, are attached as Appendix D.
`
`8. My standard practice both in 1999 and since then has been to request
`
`from a company the open market, consumer version of the product for which
`
`Imaging Resource will perform a product review. Because Imaging Resource is a
`
`website dedicated to providing comprehensive product reviews to consumers of the
`
`products, my standard practice both in 1999 and since has been to perform the
`
`product review on the consumer version of the product available to consumers.
`
`Based upon information and belief, the Casio QV8000SX camera provided by Casio
`
`to me for preparing the product review was the consumer version of the product (i.e.,
`
`the version a consumer would purchase). The photos of Appendix D include photos
`
`of the original packaging for the camera that I received (and which, as I stated in
`
`above ¶ 7, I currently have in my possession). In my opinion, the original packaging
`
`4
`
`IPR2020-00597
`Apple EX1007 Page 4
`
`

`

`appears to be packaging for a camera to be sold to a user. It is my recollection the
`
`Casio QV8000SX camera was available for purchase by the time I received the
`
`camera from Casio (by at least November 1, 1999) and by the time Imaging Resource
`
`posted the product review (January 26, 2000). For example, the product review
`
`(Appendix A at page 18) references the QV-8000 as one of the most versatile
`
`cameras on the market and having one of the widest zoom ranges on the market.
`
`9.
`
`I was not required to sign a non-disclosure agreement or otherwise
`
`restricted in any way from the distribution of materials relating to the Casio
`
`QV8000SX digital camera. Casio did not require any confidentiality from me or
`
`Imaging Resource as part of preparing and publishing the product review of the
`
`Casio QV8000SX camera.
`
`10. Attached as Appendix E is an email dated November 22, 1999, from
`
`my colleague at Imaging Resource, Stephanie Boozer, to me where Ms. Boozer
`
`refers to “working on the Casio and hope to complete it tonight or in the morning.”
`
`(Appendix E). Ms. Boozer is referring to working on the product review for the
`
`Casio QV8000SX. I know this, because my response to Ms. Boozer, also provided
`
`at Appendix E, refers to her being available to shoot test photos for the QV-8000SX:
`
`(Appendix E). Later in the day on November 22, 1999, Ms. Boozer sent me another

`
`IPR2020-00597

`
`

`

`email (Appendix F) with the “Casio text” referenced from her email in Appendix E.
`
`As can be seen in the attachment information to the email of Appendix E, the
`
`filename for the attachment was “Casio QV-8000SX.rtf.”
`
`
`
`11. Attached as Appendix G is a listing of EXIF data from an image file of
`
`an image taken with the Casio QV8000SX. As can be seen towards the bottom of
`
`Appendix G, the “Image Generated” and “Image Digitized” date is December 7,
`
`1999. The EXIF data file is the data file generated by the QV8000SX camera
`
`corresponding to a particular JPG image file stored by the camera. As shown at the
`
`top of Appendix G, the filename for the image file is “Q8DBASF.JPG.”
`
`12. Attached as Appendix H is the JPG image file for Appendix G, namely
`
`the file “Q8DBASF.JPG.”

`Manufacturer Overview
`Casio was one of the very first companies to produce digital cameras for consumers, and their original QV-10 digicam
`introduced digicam users to the wonders of LCD viewscreens. What a concept! It's become almost mandatory these
`days, but back when the QV-10 was first introduced, the feature was a real eye-opener.

`
`Executive Overview
`Casio labels the QV-8000SX as a "versatile" digital camera on its packaging, and the product certainly lives up to that
`billing. It boasts a plethora of features and operating modes, including a full 8x optical zoom lens that swivels
`separately from the body, flexible exposure options, including aperture and shutter-priority autoexposure calculation,
`time exposures up to 64 seconds(!) and much more. Here's a quick rundown of the major camera features; see the
`individual sections of the full review for more detail.
`We really like the rotating lens concept (invented by Casio, introduced way back in digicam prehistory on their original
`QV-10), and would like to see it adopted by more manufacturers. The fact that the lens doesn't protrude very much
`from the camera body is another plus, keeping the entire camera reasonably compact and pocketable (for large
`pockets, at least). Additionally, the camera is quite lightweight (due to its all plastic body), adding to its portability.
`Control-wise, all the buttons and levers are laid out so that one handed operation is possible (a definite benefit in
`some shooting situations).
`The QV-8000SX relies solely on its LCD for viewfinder operation, making it harder to use in very bright conditions, and
`also eliminating the power-saving option of using the camera with the LCD turned off. (We're big proponents of the
`dual optical/LCD viewfinder approach, as seen in Casio's QV-2000UX, which we reviewed previously.) The lack of an
`optical viewfinder also makes it more difficult to take advantage of the astonishing low-light capability of the QV-8000,
`since the live LCD viewfinder display only requires a moderate amount of light to work. For all that, the LCD is at least
`big and bright, at 2.5 inches and 122,100 pixels. An information display of camera settings and options can be
`canceled and recalled by hitting the Display button, with the exception of the flash mode icon and center focus target
`mark, which are always present. We were pleased with the optional grid function that superimposes a grid of light gray
`lines over the LCD image, significantly assisting with image composition and alignment.
`The QV-8000SX has a 6 to 48mm, 8x zoom lens (equivalent to a 40 to 320mm lens on a 35mm camera). As we
`mentioned earlier, the lens actually swivels a full 270 degrees, enabling you to point the lens all the way back at
`yourself (useful during self-timer shots so you can see the countdown on the LCD panel). Filter threads on the inside
`lip of the lens accommodate 43mm diameter filters. Focus ranges from 1.3 feet (0.4m) to infinity at the wide angle
`end and from 3.3 feet (1m) to infinity at the telephoto end. In macro mode, focus ranges from 0.4 to 19.7 inches (1 to
`50 cm) with auto focus and from 3.9 inches (10cm) to infinity with manual focus. The aperture can be manually or
`automatically controlled, with options of F/3.2, F/4.8 and F/8. A manually controlled 2x or 4x digital zoom option
`extends the optical zoom (8x) capabilities up to 32x, but with lesser image quality as a side effect. Focus options
`include Manual and Infinity modes.
`The QV-8000SX is unusual in that it provides both fully automatic and optional manual exposure modes. You thus
`
`Appendix A
`
`IPR2020-00597
`Apple EX1007 Page 9
`
`

`

`have full auto, aperture or shutter priority, or full manual exposure options. Programmed modes such as Night Scene,
`Portrait and Landscape set up the camera for special shooting, saving time with preset options.
`A built-in flash offers four operating modes: Auto, On, Off and Red-Eye Reduction. Auto puts the camera in control of
`the flash; On fires the flash with every exposure; Off completely suppresses the flash and Red-Eye Reduction emits a
`small pre-flash before firing the full flash to prevent the Red-Eye Effect. Normal flash power provides a working range
`from 1.6 to 8.2 feet (0.5 to 2.5m) and from 0.3 to 1.6 feet (0.1 to 0.5m) in macro mode and flash intensity is
`adjustable, with Strong, Normal or Weak settings.
`Six white balance modes (Auto, Daylight, Shade, Tungsten, Fluorescent and Manual) are available. Automatic mode
`lets the camera govern white values based on existing light. Daylight, Shade, Tungsten and Fluorescent settings adjust
`white balance for various natural and artificial light values. Probably the most accurate when shooting under artificial
`light, the Manual setting sets the white value based on a sheet of white paper held in front of the lens.
`Other exposure options include exposure compensation (EV adjustment), adjustable from -2 to +2 EV in .25 EV
`increments, resetting after each shot. Three metering options include Multi, Center and Spot settings. Multi averages
`the exposure based on the entire image while Center averages the values from a large area in the center of the image.
`Spot metering determines the exposure value from a small spot directly in the center of the frame.
`The Quick Shutter and Continuous Recording options enable you to catch fast paced action shots. Quick Shutter
`records up to five images in approximately one second intervals with one multiple presses of the shutter button while
`Continuous Recording captures up to five images at approximately 0.25 second intervals while you hold the shutter
`button down. Shooting intervals in both modes depend on the image size and resolution and available CompactFlash
`space. To capture moving action, the movie recording mode records up to 10 second movies in 320 x 240 pixel AVI
`format. An interesting option here is the Past movie mode, which records events that occurred before the shutter
`button was pressed (the camera actually records images to a buffer memory and once the shutter button is pressed,
`copies those images to the CompactFlash).
`You can also record a 360 degree panorama image (or up to nine consecutive shots) on the QV-8000SX through the
`Panorama record mode. A helpful feature is that after the first image is exposed, the right edge of the preceding
`image remains on the screen to help you line up the next shot properly. Images can be linked together in the camera
`(for playback only) or on the computer via the included Panorama Editor software (Windows users only).
`Other recording options include the ability to record images in monochrome black and white or sepia tones, adding a
`little creativity to your shots. The self-timer counts down from two or 10 seconds once the shutter button is pressed
`and a separate timer function allows you to record a series of images at set intervals (from one to 60 minutes and up
`to 250 shots).
`For image playback, US and Japanese models of the QV-8000SX come with an NTSC video connection cable (European
`models come with PAL) to connect the camera to your television set. If desired, the TV can also be used as a
`viewfinder when composing images, helpful in manually focusing on macro subjects, or in studio settings where you
`have to interact with the subject from in front of the camera. (Kid photography, etc.) Playback mode allows you to
`view images individually or as thumbnails, nine to a screen. You can also play back movies and panoramic images in
`the camera. A playback zoom feature lets you enlarge images and scroll around within the enlarged view.
`Four AA alkaline, lithium or NiMH batteries keep the QV-8000SX running (you can also take advantage of the included
`AC adapter). Since the lack of the optical viewfinder reduces battery conservation options, we highly recommend
`keeping a spare set of batteries with you.
`USB, serial and Mac adapter cables come with the QV-8000SX, as well as a software CD with PhotoLoader, Panorama
`Editor, Picture Works MediaCenter, QuickTime, Adobe ActiveShare, Adobe Acrobat Reader, Internet Explorer 5.0 and a
`trial version of Picture Works Web Publisher. For some reason, Casio only includes software compatible with Windows
`95, 98 and NT 4.0, so Mac users must fend for themselves, or order the $10 accessory PhotoLoader program for Macs.
`When inserted into your computer, the CD displays a detailed menu with options to install the various software
`applications, read about the applications, register your camera online, go directly to the Casio website, open the
`accessory listing or fill out an accessory order form. Most of the software included offers relatively basic image
`correction and manipulation capabilities, but the trial version of Picture Works Web Publisher creates customized web
`pages that incorporate your QV-8000SX images. Additionally, Adobe Active Share allows you to post images to the
`ActiveShare.com website for easy viewing by family and friends
`In the end, the QV-8000SX offers capabilities that both the novice and the expert photo consumer will appreciate.

`

`From the full manual capabilities to complete automatic control, the camera accommodates a variety of users. Plus, its
`compact shape and light weight make it a portable option for those of you on the go. We confess to some skepticism
`when we saw the "ultra versatile" billing on the QV-8000's box, but have to admit it's one of the most flexible digicams
`we've seen to date. (January, 2000).
`
`Design
`At first glance, the QV-8000SX doesn't look too different from some of the digital camcorders out on the market. We
`personally like swivel-lens designs, as they give the consumer more shooting flexibility in both still and movie modes.
`The QV-8000SX's lens actually turns a full 270 degrees, meaning you can point the lens back at yourself! The lens is
`protected by a lens cap that avoids being a nuisance through its ability to clip onto the wrist/shoulder strap. (A nice
`little design touch, other manufacturers take note!) As for its other design features, the QV-8000SX gives you a nice
`hand grip, via the battery compartment, and an overall sleek design. The all plastic body makes the camera
`surprisingly light weight for its size, at only 11.6 ounces (330g) without the batteries. It's also fairly compact at 5.6 x
`3.1 x 2.8 inches (142.5 x 77.5 x 71mm), excluding any protrusions.
`
`The front of the camera offers a minimalist design aesthetic, with smooth contours and few controls or features. The
`only control on the front is the slightly awkward optical zoom lever, which we've become accustomed to controlling on
`other digicams with our thumb on a back panel control.
`
`The back panel of the camera features the LCD monitor, various function controls and the Record/Play mode switch.
`Here too, the design is very minimal with clean lines and shapes.
`
`Appendix A
`
`IPR2020-00597
`Apple EX1007 Page 11
`
`

`

`Both sides of the camera are feature free, with the exception of the wrist/shoulder strap attachment on the side
`opposite the lens.
`
`The top of the camera carries the shutter button, power switch, mode dial, menu and various other buttons. The I/O
`and AC adapter jacks are covered by a plastic flap that snaps closed.
`
`Finally, the bottom of the camera holds the plastic tripod mount, locking battery compartment and CompactFlash slot.
`One note here is that the placement of the battery and CompactFlash compartments makes it impossible to change
`out either one while mounted to a tripod (a design issue we notice when doing studio work).
`
`Viewfinder
`The QV-8000SX has done away with the optical viewfinder, utilizing the LCD monitor as its sole viewfinder. In some
`respects, this makes sense since the LCD viewfinder provides a TTL (through the lens) view, and is therefore more
`true to the captured image. Alternatively, when it comes to power conservation, optical viewfinders really help squeeze
`
`Appendix A
`
`IPR2020-00597
`Apple EX1007 Page 12
`
`

`

`the most out of the batteries. Just keep this in mind and have some spare batteries
`handy. Optical viewfinders are also very handy in both very bright and very dim light,
`where the image on the LCD can be difficult or impossible to see. The 2.5 inch, low
`glare, color Hyper Amorphous TFT LCD monitor displays images at 122,100 pixels
`(555 x 220). An information display can be canceled or recalled by hitting the Display
`button, with the exception of the flash mode icon and center focus target mark,
`which are always present. There's also a very handy grid function that can be turned
`on or off, helping you line up shots. (We really like this optional grid of light gray
`horizontal and vertical lines, as we've very often ended up with digicam images that were slightly rotated, when we
`thought everything was nice and level. You can always rotate the photo after the fact in an image editor, but it's
`preferable by far to avoid the problem in the first place.)
`
`Optics
`A 6 to 48mm, 8x zoom lens comes on the QV-8000SX (equivalent to a 40 to 320mm lens on
`a 35mm camera). This is a much longer zoom ratio than is typical of digicams (most have
`only a 3x zoom), and we really liked the extra flexibility it affords. It's interesting to note the
`impact of a longer zoom on the effective camera resolution. Consider the situation where you
`want to capture a distant object, and want to fill the frame with it. If a 3x zoom will do that,
`then a 2 megapixel camera clearly wins the resolution war, with 1600 pixels horizontally.
`Suppose though, that the subject is twice as far away: The 3x zoom on a 2 megapixel
`camera ends up only delivering 800 pixels worth of resolution on the subject itself (assuming
`that it now only fills half the frame). Compare this to the QV-8000, which could zoom out to
`6x, and fill the frame with the subject, devoting the full 1280 pixels to it. In this case at least, the QV-8000 actually
`delivers more useful resolution than the 2 megapixel model. Then consider that the QV-8000 goes all the way out to
`8x! For distant subjects (wildlife?), the QV-8000 is actually a better choice than a 2 megapixel camera with only a 3x
`zoom (or even a 5x zoom).
`We really liked swiveling lens on the QV-8000, which rotates a full 270 degrees, letting you point the lens all the way
`back at yourself, straight down or anywhere in between. Filter threads on the inside lip of the lens allow you to attach
`43mm diameter filters or accessory lenses. Focus ranges from 1.3 feet (0.4m) to infinity at the wide angle end and
`from 3.3 feet (1m) to infinity at the telephoto end. In macro mode, focus ranges from 0.4 to 19.7 inches (1 to 50 cm)
`in auto focus and from 3.9 inches (10cm) to infinity in manual focus mode. Aperture can be manually or automatically
`controlled, with options of F/3.2, F/4.8 and F/8.
`
`The 1cm minimum focusing distance in Macro mode can produce some really amazing close-
`ups. The zoom lens seems to have a much more limited range of focal lengths in macro mode
`(we'd guess it's only about a 1.2x zoom at that setting), but the detail the camera can
`capture is incredible: The minimum capture area is an amazing 0.71 x 0.95 inches (18 x 24
`mm). The only limitation we found with this incredible macro capability is that the width of
`the lens itself can make it difficult to get adequate light into the subject: You may find it helpful to make a conical
`"light tent" out of a piece of white paper or diffusion material, as shown at right. With this sort of arrangement, you
`can shine lights onto the diffusion material from multiple angles, and obtain very even illumination, despite the
`extremely short working distance. You do pay one price for the extraordinary macro capability: At the shortest
`focusing distances, the lens appears to suffer from considerable "curvature of field", which means that the corners of
`the image will be out of focus when the center is sharp. This effect is most noticeable at the 1cm focusing distance,
`decreasing as you move out to greater distances.
`A 2x / 4x digital zoom option extends the 8x optical zoom capabilities up to 32x, but the image quality always suffers
`as a result of digital enlargement. Digital zoom automatically saves images at the 640 x 480 pixel size. The QV-
`8000SX offers manual focus and Infinity modes, both accessed by a control button beneath the LCD monitor. Manual
`focus is adjusted by the plus and minus buttons on top of the camera, after pressing the MF button under the
`viewfinder. After a few seconds though, the +/- buttons return to their normal exposure-compensation function. No
`focus feedback is provided other than the view in the LCD: For fine focusing, we'd like the option of having feedback

`from the camera, or at least being able to see a magnified view in the LCD. Infinity mode sets the focus at infinity for
`quick shooting of far away subjects.
`Exposure
`Exposure control on the QV-8000SX can be fully automatic, or you can take advantage of several programmed modes.
`Aperture and Shutter Speed Priority modes allow you to control either the aperture and the shutter speed individually
`or both at the same time (full manual). In the menu system, both aperture and shutter speed have entries with
`options of "Auto", or several manual settings. Picking a manual setting for aperture, but leaving the shutter option set
`to auto results in "aperture priority" metering. The opposite set of choices produces "shutter priority" metering.
`Manually selecting values for both settings gives you full manual exposure control, a very rare commodity in the
`digicam marketplace. Additionally, program modes such as Night Scene, Portrait and Landscape save time when
`shooting in special situations. While in full automatic mode, you have the ability to change white balance, exposure
`compensation (EV) and the flash. You also have control over image sharpness, color saturation and image contrast
`through the Record Details menu. Here's a more detailed description of the QV-8000SX's exposure options:
`
`Flash
`The built-in flash on the QV-8000SX resides directly on top of the lens, so that when the lens spins around, so does
`the flash. This is convenient, and almost mandatory for a rotating-lens design like the QV-8000, but the close
`proximity of the flash tube to the lens makes it much more difficult to eliminate the red-eye effect in shots of people.
`Four flash modes are available: Auto, On, Off and Red-Eye Reduction. Auto mode puts the camera in charge of judging
`light levels and whether or not to fire the flash. The On setting fires the flash with every exposure and the Off setting
`prevents it from firing at all. Red-Eye Reduction mode emits a small pre-flash before firing the full flash to help
`prevent the occurrence of the Red-Eye Effect. Working range for the flash runs from 1.6 to 8.2 feet (0.5 to 2.5m) in
`normal, wide angle mode and from 0.3 to 1.6 feet (0.1 to 0.5m) in macro mode. An icon on the LCD monitor clues you
`in to the selected flash mode, which is changed by pressing the Flash button until the desired icon appears (Auto mode
`has no icon). Flash intensity can be changed via the Record Details menu, with options of Strong, Normal and Weak.
`We'd loved to have seen an option for external flash on the QV-8000, given the extraordinary flexibility it offers
`otherwise. The good news here though, is that its flash is a "single pop" design, producing only a single flash in normal
`operating mode. This makes it easy to use with conventional optical strobe triggers for use with external flash units.
`(Many digicams produce a double flash in normal exposure mode, the first "pop" being used for white balance and
`metering, and the second making the actual exposure. These cameras require special "smart" triggers to sync properly
`with external strobes.)
`White Balance
`Six white balance modes are available on the QV-8000SX: Auto, Daylight, Shade, Tungsten, Fluorescent and Manual.
`In Automatic mode, the camera assesses light type and levels and assigns the appropriate white values. Daylight,
`Shade, Tungsten and Fluorescent settings all do as they sound by adjusting white balance for varying natural and
`artificial light sources. Manual white balance allows you to set the white value based on a sheet of white paper held in
`front of the lens (usually the most accurate in special lighting situations). A little-known benefit of manual white
`balance options like this is that you can use them to deliberately introduce color casts into your images, by using off-
`white objects as your reference targets: Experiment with this a bit, and see what happens!
`Exposure Compensation (EV adjustment)
`To adjust for lighter or darker exposures, exposure compensation (EV adjustment) is adjustable from -2 to +2 in .25
`EV increments. The setting is only good for one exposure, as the EV value automatically reverts to zero once the
`shutter button is pressed.
`Metering
`The QV-8000SX allows you to change exposure metering options via the Record Details menu with options of Multi,
`Center and Spot. The Multi setting takes readings from the entire image and then bases the exposure on the average
`of those values. Center weighted metering averages the values from a large area in the center of the image. Spot
`metering takes the exposure value from a reading at the direct center of the image. Unlike the EV adjustment setting,
`the metering setting can not only persist from shot to shot, but from one shooting session to the next, even if the

`camera is powered down in the interim. You can select whether or not the camera remembers the metering preference
`via a setting on the "Mode 2" options menu.
`Quick Shutter
`The Quick Shutter function allows you to record up to five images at approximately one second intervals (depending
`on image information and memory card space) with one press of the shutter button. The mode can be used in
`Automatic, Night Scene, Landscape or Portrait recording modes. As you shoot, the camera continuously processes the
`images you've already captured in the background, saving them to the memory card. When you pause, the camera
`"catches up" with you, and when you shoot rapidly, you get ahead of it. The camera displays the current status of the
`memory buffer (temporary image storage) as you shoot and it processes, via a set five small circles in the LCD
`viewfinder. Filled-in circles indicate full memory spaces, empty ones indicate space available. We found both the Quick
`Shutter mode and this memory-usage feedback very useful in our shooting: It's nice to know what's going on inside
`the camera, and it helps you plan your shots a bit.
`Continuous Recording
`The Continuous Recording option allows you to record up to five images at approximately 0.25 second intervals with
`one press of the shutter button (depending on the image information and
