Review of the Fuji FinePix Real 3D W1 camera
By Donald E. Simanek
Stereo photographers may have an excuse for going digital, now that Fuji offers this 3d camera with many of the features they want, all packed into a sleek and compact camera. It does exactly what good stereo requires: It takes two pictures simultaneously, one for the left and one for the right eye, which can easily be computer-processed for viewing in any format now in use. Add to that its 2d capabilities, and you have one camera that does it all.This page requires a monitor width of at least 1000 pixels in order to see both images for cross-eyed stereo viewing. Since the photos also have large vertical dimension, it helps to toggle the "full screen" view (F11 in Windows). However, if you haven't mastered that viewing method, these pictures may also be appreciated as 2d flat photos. All are © 2008 by Donald Simanek.

Can internet reviews be trusted?[This section was written due to my dissatisfaction with internet camera reviews, and was written before I had had the camera in my hands. If you want the actual review based on actual use, skip to the next section.]
The Fuji FinePix REAL 3D W1 digital camera has just been released. I haven't seen one yet, nor has my order from Japan reached me [Oct 1, 2009]. But before ordering it I read numerous reviews of it on the internet, and I read Fuji's own web documents about it. These reviews say more about the reviewers than they say useful things about the camera. One even went to far as to say it was the worst camera ever made. He must have very limited experience with cameras, and the ignorance displayed in his review shows that he certainly hasn't much experience with stereo photography.
Some reviewers do admit that they had only an hour of hands-on experience with the camera. That probably isn't enough time to read the instruction manual. Others had "seen one" at a trade show. Yet they feel qualified to pontificate on it, and in the process make mistakes that any knowledgable stereo photographer will recognize as untrue statements. Before I write my review (below) I'd like to cite some of these.
Results of my early tests.My comments below will focus on this camera as a stereo camera, for that's the reason people will want to buy it. The camera's 2d capabilities are a nice to have, perhaps, but stereo photographers will seldom use them.
[6 October, 2009] The camera arrived this morning. My first impression is positive. The case is black enameled metalonly the sliding lens cover is plastic. The camera has a solid feel. Some reviewers complained that the tripod screw socket was plastic. Maybe theirs was, but my camera came with a threaded solid metal socket. The controls are a bit differently configured from other digital cameras, but most of the functions we expect on such cameras are there, plus the extra 3d functions.
Some web reviewers stated that this camera has no autofocus assist lamp. They were wrong. This function is provided by a light hidden behind the blue "3d" of the logo on the front of the sliding lens cover! (See the front view picture above.) It functions only in low light situations.
The back of the camera has toggle controls for many functions, on both sides of the large LCD screen. These often have several functions, designated by icons that are a bit smaller than I'd prefer. They obviously wanted to keep the camera as small as possible.
Various shooting modes may be selected, hidden in the menu under "scene positions". These include the usual ones: auto, manual, aperture priority (f:8, 5 and 3.7 only), night, sunset, sports, close-up, party, and options you may never use, even if you did remember they are available. The camera has the usual flash choices: forced, suppressed, auto, and anti-red-eye.
The 3d LCD display on the back isn't as annoying as I expected, and it can be switched to 2d even when shooting 3d. I charged the battery for a couple of hours, put in a memory card, formatted it, and these were the first four pictures I took:
Fall crocus. Subject partly in sun, partly in shade.
Cropped version of the previous subject from a different angle, to show detail.
None of the pictures above above have been enhanced or tinkered with except the cropped one. The camera was on "normal" (the default) quality and with its "Fujichrome emulation" option, which enhances colors. Otherwise the camera setting was "Auto" everything.
Photographing stereo action requires perfectly synchronized shutters, and this camera has them. So I took a day with the Fuji camera just to shoot the many waterfalls at Rickets Glen state park in PA. The falls are in a deep gorge, and it was a cloudy day, so some pictures were a bit dark and required gamma correction. I also reduced them linearly to about 1/5 original size, for display on this web page, and sharpened them for clarity of details. This is always recommended for pictures reproduced on websites.

Lessons learned from this expedition:
Adding things.The design of the camera doesn't make it easy to add accessories on its front. Most compact digital cameras are similarly unfriendly to the tinkerer.
My preliminary tests suggest that the camera works if a linear polarizer is used (large enough to cover both lenses}. My experiments suggest that you don't need a circular polarizer (many digital cameras require them), but if you had a circular polarizer that large, you could use it. Polarization helps increase saturation of colors of foliage, and can darken blue skies. It is also handy for blocking specular reflections from shiny surfaces and from water surfaces. Still, it's not very practical with this camera, for it is so easy to get light reflections in the polarizing sheet when the sun is behind you.
The flash lamp located between the lenses gives conflicting and disturbing shadows in close ups and portraits when there's a wall behind and near the subject. This is more annnoying in 3d than in 2d. The flash works nicely for medium distance shots, though, and to fill in shadows in otherwise well lighted scenes. But this is a problem with compact 2d cameras as well. There is no provision for plugging in an auxiliary or remote flash, but one can use the camera's fill flash lamp to trigger an external flash, using an inexpensive solid state flash trigger device designed for digital cameras. (It must be able to ignore the single pre-flash.) I tried bouncing the camera's built-in flash from a ceiling, a trick I've used successfully with other such 2d cameras, but the picture was severely overexposed. I have not figured out where the sensor is located that measures the scene's illumination, but I suspect it is integrated into the left lens. Still, I'm puzzled why deflecting the flash to the ceiling confused the system. It is a pretty standard trick that I've used successfully many times before with other digital cameras.
Picture Quality.I've seen internet reviews that complain about the pictures from this camera having low image quality, digital noise in low light, and occasional lens flare. I have taken over 200 pictures with mine so far, in various lighting conditions, including daylight situations where you might expect lens flare, and haven't seen any evidence of that. But I avoid shooting toward the sun. As to quality, the pictures have far greater pixel count and resolution than I need, and the color fidelity is fine, I see no geometric distortion even at wide angle settings (like barrel distortion which is common in compact digital cameras). I have examined the individual pictures taken in daylight at the highest magnification and see no noticeable spherical aberration, chromatic abberation, or coma. At larger apertures, some of these faults are just detectable at extreme enlargment. I can't understand what these critics expect of this camera. It's a 3d camera, and I don't think anyone is going to blow up the pictures to make 3d murals. The 2d capability is only a minor reason for this camera's existence, and the quality is still more than I need. The best test would be to digitally project the pictures onto a theater-sized 20 foot wide screen for polarized viewing. But even stereo clubs often don't have equipment for this yet, or couldn't afford it, certainly not any digital projectors matching the capability of those used in 3d movie theaters. The digital projectors in school classrooms don't have anywhere near the resolution and quality of the pictures from the Fuji 3d camera.
Perhaps some camera club should do a double-blind test with a real audience viewing 2d pictures on a large screen from various high end 10 megapixel cameras and 2d pictures made with the Fuji 3d camera, and see whether they can really tell which pictures were taken with the Fuji. They might also compare with 35mm film slides from 1950s stereo camaras. I suspect the outcome would show that there's only slight discernable difference. I'd love to see the results.
The camera stores pictures in MPO format (which is a JPEG format that stores multiple images in one digital file). It can be set at either of two levels of compression, FINE, or NORMAL (the default). These are set with a menu accessible from the very small f button at the lower right corner on the camera back. Some new users don't discover this right away, and its mention in the camera manual is brief.
Another thing users don't discover is the P (preset) mode, selectable from the menu. The camera's instruction book is absolutely no help here. This mode retains automatic functions, but allows you to set the ISO sensitivity to a selected value. (Settings chosen in the P mode are remembered by the camera for the next time you select P mode.) Try setting the sensitivity to ISO 100 for well-illuminated scenes without rapid movement, and you may see a great improvement in picture quality, sharpness and reduced digital noise.
Potential buyers should realize that this is a point-and-shoot digital camera, not a high-end professional camera. It's only storage format is JPEG, there is no TIFF or RAW storage option. It has no provision for external flash, so if you need that, you'll also need a wireless remote flash. Be sure to choose a slave flash or slave flash trigger than can ignore the camera's single pre-flash. These aren't expensive.
I even sense a subtle photography snobbery at work here. Canon and Nikon owners act as if anything from Fuji or Pentax is unworthy of consideration. I'm reminded of the wine 'experts' who, in a double-blind taste test, couldn't tell their expensive favorite wines from some of the less expensive "no-name" brands.
The quality issue, take 2Talking about picture quality is a murky exercise. Illustrating it on a web page is also difficult, since web page pictures must be reduced in size. But here's an attempt to give readers a sense of it. I took a picture of our department secretary, Barbara Greene (usually a good sport about such things), and show the full picture at the left (reduced in size, of course). The original was 3602 x 2733 pixels. It was taken hand held at the wide angle setting, with available fluorescent light (no flash), so the camera kicked into its highest sensitivity mode (ISO 1600). This would be expected to cause the most digital noise and lowest resolution. I.e., it is a worst-case example. At the right is just a portion of the same picture without size reduction. Arty, isn't it? The look is her usual "What are you up to this time?".
If one really wanted a close-cropped portrait, the camera lens could have been set at its "tele" (narrow angle) setting, for much better result. Or external bounce flash could have been used. This picture was deliberately made to push the limits of this camera's performance. Here's how to do it, hand held, no flash:
Picky, picky. What's 1/3 degree?But, back to the real world. I have noticed that SPM reports a rotation disparity between the L and R pictures, from 0 to 0.7 degrees, averaging about 0.3 degrees. But SPM's "auto-alignment" function fixes this neatly and perfectly, so it doesn't concern me at all. Whether it would even be noticeable with Fuji's $500 autostereoscopic frame viewer I can't say. Probably not. It doesn't matter to me, for I dislike autosereoscopic systems, and certainly wouldn't pay that much for one.
Slight image rotation and vertical disparity of this amount is common in stereo cameras and stereo adapters. When Loreo macro LIAC pictures are processed by SPM, it reports correction of rotation of about half a degree, and it corrects for an easily noticeable vertical disparity. The vertical disparity of my Fuji 3d is a much smaller amount than my Loreo; just a few pixels. I suspect that even the hallowed Stereo Realist had these "defects" as well, due to "play" in film tracking. Meticulous stereo photographers were used to correcting this when aligning the pictures in aluminum masks and mounts, especially if the stereo pictures were destined for projection on a screen or entered in stereo competitions be rated by overly 'picky' judges.
3d movies.The camera also takes movies, in 3d or 2d, at 30 fps, and either 640x480 or 320x240 pixel size. I don't have the experience to compare it to other digital movie cameras. I have recorded several movies, and processed them with Stereo Movie Maker (you need to install a m-jpeg codexI bought the Morgan codex). My results were interesting, but these large AVI files seem to be too much for my computer's speed, for the playback is jerky. (AVIs from other sources are jerky also, so I don't blame the camera.)
The camera's automatic functions work, but not during movie acquisition. That is, you can set the focus and zoom before filming, but these will be then fixed during movie acquisition. Of course, you can record a scene, stop recording, then record another scene with different focus and zoom setting. I can understand why Fuji designers chose not to implement zoom and autofocus in 3d mode. This capability would considerably increase the cost of the camera. (Imagine correcting focus every 1/30 second.) Besides, with such short focus lenses there's plenty of depth of field to cover most action. Also, zooming during filming is annoying enough to watch in 2d; it would be mind-jarring in 3d. It is OK for occasional special effects, but it shouldn't be casually or frequently used. Recall recent 3d movies you have seen in theaters. The best of them are careful not to use zoom much, and also careful not to change the apparent distance of the center of interest abruptly between scenes. Filming 3d movies requires a different approach than 2d to produce results that are comfortable to view.
The "automatic convergence" (actually window distance) control also does not function during movie filming. It is linked to autofocus, and autofocus does not function during movie filming. This would be of no concern if you could adjust the window dynamically in StereoMovieMaker. But you can't. I can imagine the clever folks who wrote SMM are right now thinking of how they could add that feature.
A short stereo movie sequence in AVI format with the least JPEG compression can result in a file of gigabyte size, which chokes my email server, and even uploading it to my web pages takes too much time for me. StereoMovieMaker allows you to output the file with any level of compression. I get manageable file sizes with compression set at 33% (the default is around 90%). 100% is zero compression. But greater compression reduces quality noticably. The quality of these movies (with least comression) seems to be comparable to that of other digital camera AVIs of the same resolution, and better than most 2d AVIs I've seen on the web.
The Convergence Myth.Some people think that a 3d camera should allow automatic or manual convergence of the lens axes, on the mistaken view that the camera should duplicate the convergence of the human eyes. This is simply not a good idea. Stereo cameras of the 50s had lens convergence fixed at about 6 to 9 feet. That made the lens optic axes nearly parallel. When you view stereo pictures, by any method, your eyes do the convergence on individual objects in the scene, and this eye convergence action is what gives your brain the stereo relief effect. The Fuji 3d camera's design is much the same, and the lens optic axes are fixed and not adjustable. The Fuji has a "convergence control" on the back, which is misnamed. It does not control the lenses in any way. It only controls the "frame" or "mask" surrounding the picture, which affects the apparent distance of the "stereo window" when the picture is viewed. It puts the window at just about the distance of the subject the camera autofocused on. This prevents the camera from recording parts of the scene that do not appear in both images (and would have no 3d effect. Ideally, the window should appear closer than the nearest object in the scene, but the camera isn't that smart. You should adjust the stereo window later, using StereoPhotoMaker. In fact, I never fuss with the camera's convergence control. I just leave it on "auto" and then adjust the stereo window later. This convergence control is useful when viewing your pictures on the camera's LCD screen, to make close-ups easier to view.
Things to love about this camera.Those of us who have previously taken stereo photos with film stereo camereas have often felt limited by the rather narrow horizontal angle of view of those cameras and of the available hand-held viewers. Beam splitter adapters were much worse, cutting this horizontal angle in half. The stereo realist gave us only 36°, which is why some of us bought Busch Verascope cameras (in spite of their faults) which gave us 40°. The Fuji 3d, in its default (wide) setting gives (by my rough claculations) more than 50°. Add to that the exceptional depth of field of short focal length lenses, from a few feet to infinity, and taking pictures like the one below is a snap.
(Picture of Pine Creek taken Oct 10, 2009 at Black Walnut Bottom access area, Pennsylvania.)
Detail is sharp from the rocky creek bottom a few feet away, to the shoreline rocks and to the distant wooded hills. My analytic mind made me suppose that such wider angle pictures would look bad with narrower angle viewing methods, and nearly all viewing methods are narrow angle except IMAX movies. But I was wrong, and I find the wider angle pictures to be quite effective and pleasing to view.
Another advantage of the wide view is that it also covers greater height. Tall buildings and trees can be photographed, then cropped from the sides to a taller than wide format. With 2d cameras, we'd turn the camera 90° for such pictures, but you don't dare to that with stereo.
A lot of unphotogenic content was cropped from both sides of this scene. Yes, I was standing on the centerline of the road. Traffic is light in this remote part of Pennsylvania.
The ability to quickly zoom from wide to tele setting is a luxury we never had with film stereo cameras. It's often a good idea to take a narrower view picture just after taking a wide one, to remove unwanted elements from the picture when it's not possible to move closer.
Here's an example of a telephoto stereo that was even further tightly cropped to remove a lot of water, and two other ducks.
I was concerned that the 77mm stereo baseline, significantly wider than the spacing of human eyes, might give exaggerated depth. But eye-brain stereo physiology is a strange thing. With standard viewing methods, the pictures from this camera look fine to me, and if they do have depth exaggeration, it looks good in most scenes. The larger baseline is not good for portraits and closeups, however. One should avoid having distant objects in such scenes, for they will be distracting. This is true with any stereo camera.
The automatic mode of this camera is addicting in its convenience and good "judgment". I predict most pictures taken with this camera will be taken with full automatic. I have yet to take a picture in automatic mode with this camera that was not well-exposed and sharply focused. A few did require a slight gamma tweaking with software, due to my own haste in taking the picture when the center focus area was on a very bright object.
Some of us like panoramic pictures, and have been taking such scenes in 2d panels with slight overlap, then stitching them together with smart software like the PanaVue Image Assembler (my favorite). The 2d mode of the Fuji camera has a feature to facilitate this. You can take one panel of a panoramic, with the camera saving a copy of it and displaying a phantom copy of it in the viewfinder to aid in aligning and overlapping the next panel, and so on.
This same feature can be used, in the camera's 2d mode, for taking a cha-cha pair that will be later become a larger or smaller baseline stereo picture, using StereoPhotoMaker or similar software. This, along with the camera's macro capability, can be useful for macrophotograpy. These are methods we've long been using with 2d cameras, and are described elsewhere. See shifty methods for taking stereo pictures.
[October 24, 2009] The Fuji 3d camera allows macrophotography in a much better way, if you are willing to construct an inexpensive and simple (but tricky to assemble) accessory device. See Macrophotography With the Fuji 3D Camera.
Prelimary conclusions.Stereo photographers are not used to camera automation, but they can adapt to it if the results are worth the trouble. The positive features of the Fuji 3d camera outweigh its nuisance features, and many stereo photographers will be won over. Just being able to use synchronized zoom lenses from wide to mild telephoto is a wonderful convenience. At the default wide setting, the camera covers a horizontal angle of view almost twice that of the classic Stereo Realist camera. I find myself using that setting most of the time, reserving the option to crop the pictures later, an easy operation with StereoPhotoMaker.
The default 4:3 (a bit wider than high) picture format is my favorite, but other choices are available. The nearly square format that stereo photographers have been using for years need not constrain us any more. [A firmware upgrade 2.0 is now available online from Fuji to provide a 16:9 picture format option.]
The Fuji 3d has most of the features one expects in compact digital cameras that we never had in film stereo cameras (except for very expensive custom-made stereo cameras). Automatic color balance. autofocus. auto-exposure. automatic sensitivity setting. For those who shun such amenities, there's an option for completely manual operation. In automatic mode the ISO (sensitivity) setting is chosen by the camera, determined by lighting conditions; the user must choose one of the other modes to lock its value. In "auto" setting the camera seems to be smart enough to make the right choices. This is another thing longtime stereo photographers may find takes a bit of getting used to.
But there are surprising omissions, features one would expect in any pocket digital camera these days. Since this camera consists of a melding of "off the shelf" technologies, one wonders what they were thinking to omit certain functions that any professional photographer would expect and want. (One can't avoid comparing the specifications and design features of the Fuji 3d with the Finepix Z-series cameras.)
If we held back, waiting for perfection, we wouldn't be using computers, or driving cars, or talking on telephonesand we'd all be single. Donald Simanek
