|My Thoughts on the Canon 5D Mark III Camera
Friday, March 2nd, 2012
Canon finally announced the long-awaited 5D Mark III camera body early this morning. My thoughts?
I’m sure it’ll be a nice upgrade when my 5D Mark II dies.
That’s right, I will not be rushing out to buy one of these. I was waiting with as much anticipation for this camera as anyone, and was ready to hit the “preorder” button as soon as the listing came up on B&H. But after reading about the camera it does not appear that its features will be worth an immediate upgrade.
There were a few things I was hoping Canon would include in this camera:
1) a faster continuous shooting still frame rate
2) faster video framerate(s)
3) a better autofocus system
4) higher-quality video recording
1) and 4) were improved slightly, but not much. The 5D Mark II’s continuous shooting framerate is 3.9 frames per second. The 5D Mark III’s is 6fps. This is an improvement, but only by about 50% and still doesn’t even match the 7D’s 8fps. As far as video recording, the 5DmkIII uses a new interframe compression scheme and additional processing which may improve the quality of the video, but it still uses the same old 4:2:0 sampling scheme. 2) was not improved at all (the 5D3 can shoot 720 60p, but so can the 7D and, for that matter, so can a $200 GoPro camera… I wanted 1080 60p, which I think is very reasonable*). 3) really is the only one of these four things that was significantly improved. The 5D Mark III was given the same AF system as the 1Dx, Canon’s flagship camera body. It is a 61-point AF system with something like 40 cross-type AF points (the best kind). Also, it uses a tiny, 1.5% spot metering area (the circle is only 1.5% of the total area of the frame) which is great if you want to expose the shot very precisely for a specific area of the image.
Anyway, again, all in all, not worth buying immediately.
*: The 5D Mark III is equipped with one of Canon’s newest, most powerful image processors, the Digic 5+ (the same processor that the 1Dx contains, except the 1Dx has two of them), so it is very possible that the good folks at Magic Lantern will be able to engineer some third-party firmware for the 5D3 and if so, it is possible that they’ll be able to squeeze additional performance out of the camera. We’ll just have to wait and see on that one.

Canon 5D Mark III in the wild?
Tuesday, January 24th, 2012
As every professional photographer knows, the as-yet-unreleased successor to the Canon 5D Mark II camera body has been an immensely anticipated new product. For non-photo professionals, think of it as the “new iPhone” of cameras: everybody’s talking about it, what features it’s going to have, what it’ll be able to do, how much it’ll cost, and most importantly, when it’s going to come out. The 5D Mark II is now over three years old, and is overdue for an update. There have long been rumors that its replacement will be called the 5D Mark III, but pretty much everything else about the camera has been a mystery. Canon sponsors (read: pays) a number of high-profile photographers and allows them early access to new, unreleased equipment and the rumor has been that these photographers have had their hands on the 5D Mark III for some time. These folks are all under legally binding contract not to talk about anything they see early though, so the pro photography world is holding its breath in anticipation.
Well, we just got the biggest hint yet. A wildlife photographer named Stephen Oachs (who is NOT sponsored by Canon and is not under NDA) is currently on safari in Kenya and spotted a Japanse man using unreleased equipment. Oachs, being a wildlife photographer on safari, had a camera and a long lens on hand, and snapped a number of photos of the man and the equipment he was using. The most important image is here:

Photo by Stephen Oachs
Stephen was even so kind as to publicly post the raw file of this photo as proof that it was not faked or manipulated in any way. After cropping and rotating the image for easier viewing, it looks like this:
A few things are clear from this photo:
- -The camera this man is using is not a 5D Mark II (the control layout is all wrong, among other things)
- -It also isn’t a 7D (no pop-up flash and the button directly above and to the left of the rear scroll wheel doesn’t exist on a 7D)
- -It also isn’t any version of a 1D (the battery grip is a screw-on attachment, not integral to the camera body)
So it is clear that this is an unreleased camera. It is possible that this is a replacement not for the 5D Mark II but the 7D (a “7D Mark II”?), but seems unlikely, since the 5D Mark II should be ahead of the 7D in terms of an update and since the optical viewfinder prism looks too big for the camera to be crop-sensor.
By the way, it is also clear that this unreleased camera includes substantial video functionality, since it includes a prominent still/video switch just like the 7D.
There are now inklings coming out about a Canon announcement on Feb. 7, so it sounds like photographers’ long wait for the mythical 5D Mark III may be about to end.

Back to a Favorite Spot
Wednesday, August 24th, 2011
We’ve all got favorite places; places that for whatever reason we keep coming back to, whether it’s because they’re pretty, they’re comfortable, there are good people there who we enjoy spending time with, whatever.
The weather has been beautiful in Boston for the last couple of days (with the exception of that earthquake yesterday! Does that count as weather?), and I had some free time last night so I decided to go back to one of my favorite places in Boston for shooting at night.
The Longfellow Bridge connects Cambridge and Boston across the Charles river, and looks out on the part of the river known as the Sailing Basin, because as the widest, most open part of the river, the MIT, Harvard and other university sailing teams, as well as the public all use it as a great spot for sailing small boats. On any given afternoon there are dozens of sailboats on the water here.
This spot on the bridge is a favorite of mine because in addition to the great view of the river, from this vantage point there is also a great view of the Prudential building and the Hancock Tower, Boston’s two tallest skyscrapers, and the bridge faces southwest, meaning it is wonderful for shooting landscape photos at dusk.

For this image, because I knew I wanted both the natural light in the sky as well as the artificial lights inside the buildings to be visible with a nice balance between the two, it was important to wait for just the right light. I knew that would mean in this case that would mean a little bit after sunset, when the sky had dimmed sufficiently to not overpower the artificial lights (sunset photos can be gorgeous, but I’ve found that often the best light is actually after sunset, such as here). With the camera on the tripod and using a wide-angle lens (my trusty Canon 5D Mark II with the superb EF 17-40mm f/4L lens), I stopped the lens down to f/8 because shutter speed wasn’t going to be an issue (thank you, tripod) and I wanted the little bit of extra sharpness that comes with a smaller aperture. Using a remote cable release to fire the camera to avoid shake I fired a few frames to test exposure (the camera’s internal light meter here is a decent starting point but only a starting point) and play with a few different angles. Since I wasn’t using a tilt/shift lens and the camera needed to be angled up to get the framing I wanted, I had to do a bit of digital alteration in post (Photoshop’s “Lens Correction” function) to remove the distortion and make the buildings straight.
The result is what I think is a nice image, somewhat different than ones I’ve taken here before. It is by no means perfect though (if in fact an image can ever be), so I’m sure that I’ll be back to this spot again some time.

First Shot From Trip Out West
Tuesday, April 26th, 2011
I haven’t had much free time since I got back from my trip out west, and today was the first chance I had to even look at the still photos I shot while I was there. I shot such a huge quantity of material during the course of the three weeks (in Utah, San Diego, Los Angeles, and finally Las Vegas) that there are a lot of shots that I don’t even remember taking. There are a few, though, that I remember very clearly, and this is one of them.
This photograph was taken in a remote section of the backcountry of Zion National Park in southwestern Utah.

Before I shoot any photograph I always try to have a picture in my mind of how the image will look when it is finished. There are certain scenes that just scream out to be displayed in black and white. This was one of those times – I knew before I even shot the photo that I was going to convert it from color to black and white when I got back to the computer (one of the conveniences of digital photography).
I don’t know why this particular scene was so striking to me – it had something to do with how the loose stones were strewn around on the slickrock, how their shadows contrasted with the unbelievably strong, bright sun.
P. S. – As a side note, this image illustrates both the advantages and disadvantages of digital photography. My digital camera gave me the ability to shoot the photo in color and convert it to black & white afterwards (whereas in the days of film I would have been forced to either A) shoot the image on whatever type of film I happened to have in my camera at the moment or B) pull the roll of film out and waste whatever I hadn’t used), which of course is a big advantage.
A big disadvantage with digital photography, though, is that I, as a photographer, have a lot less control over how you, the viewer, see my images. In the days of film, if I printed a photo onto a piece of photographic paper in a darkroom and then showed it to you, I could be pretty sure you would see it almost exactly as I did – the colors would look the same, the lights and darks would be the same light or dark. With digital photography, on the other hand, since this image is being viewed on a computer screen, I can’t actually even be sure if you, the viewer, are seeing the image the way I intended it. The reason for this is that computers (both through software and hardware) all display color and luminance (how bright something is) differently. So in the case of this image, I intended parts of the sky to be dark, but not completely black. But your computer screen might show the image with parts of the sky completely black, so you may not be able to see some of the detail that I intended.
I’m sure eventually technology will solve this problem, but for the moment it is just a weakness of digital photography that photographers have to live with.

Zaza Gallery Canvas Photo Print Review
Wednesday, July 7th, 2010
So about a month ago (jeez, it’s been a month already…!) I wrote that a company called Zaza Gallery that makes canvas photo prints had offered to give me a free canvas if I would review the product here on the blog. The technology that drives many of today’s photo products is evolving so rapidly that I’m always interested in hearing about and trying out new vendors, so I was happy to take them up on it.
Their initial offer was for a 16″ x 20″ photo canvas. I shoot on Canon cameras, whose sensors are built with a 3:2 aspect-ratio frame (meaning the width of the image is 1.5x the height) and like many pros, whenever possible I use the entire frame when composing my shots (this is a good practice, as it maximizes the sensor area that you’re using for your final composition, thereby maximizing the image quality). As a result, the 16×20 canvas was a different aspect ratio (5:4) than my intended composition. I brought this to the attention of the company, and they generously offered to instead provide me with a 16×24 canvas, which matched my images’ 3:2 aspect ratio.
Zaza directs that for best quality, the image file that customers provide for printing have a resolution of 300 dpi in order to preserve detail in the final print. This is good, because in order to achieve the great detail of true professional-quality prints, high resolution is essential. For a 16×24 print though, this works out to 4800×7200 pixels, or approximately 35 megapixels, which is a higher resolution than even the best pro cameras widely used today (there are a small number of exotic systems that can achieve this resolution natively). What this means is that to make a Zaza canvas print properly, photo-editing software such as Adobe Photoshop or Lightroom is needed to increase the resolution of image files (known as “up-resing”). Since up-resing can result in nasty pixelation, artifacting and other image degradation if not done carefully, images that will be used to print high-quality prints such as canvases must be originally captured in the highest resolution possible.
In any case, for this test canvas, I chose to use one of my more recent photos (featured previously on the blog as the first Photo of the Day, here) which I called “Daybreak”. Here is the photo:
I chose to use this photo because it would really put the Zaza printing process through its paces: With its heavily saturated colors it would test Zaza’s ability to color-match, the absolute blacks in the silhouettes and sky would test the ability to achieve true black, and the smooth fade-to-black in the sky would test Zaza’s ability to print smooth gradients.
I prepared the image file according to Zaza’s specifications, with the appropriate resolution, format (Zaza takes standard JPG files) and embedded sRGB color profile (color profiles are essential for accurate color reproduction) and sent the image off. In about a week and a half (which is a normal turnaround time for canvas prints like this) I received the finished canvas. It was packaged well-protected, in a cardboard box in a plastic bag covered in bubble-wrap. Here is the finished canvas:
Zaza offers a number of different wrapping style options – a traditional “gallery wrap,” in which the image extends beyond the edges of the frame and continues on the sides, white and black wraps, in which image extends only to the edge of the frame and the sides are white or black, and finally “mirror wraps” and “blur wraps,” which are the best of both worlds: the image extends only to the edges of the frame (meaning the image is not cut off), but the edges are colored either by a reflection of the edge of the image or a blur of the edge of the image (which is nice so that the sides, if visible when hung, have some color and look like a real gallery wrap). I elected for the blur-wrap style. I haven’t seen this option with other canvas print vendors, and it is really nice. Your image doesn’t get clipped, but you still get nice coloration on the sides of the frame.
The quality of the final product is very good. The frame is sturdy and the canvas is stretched quite taut and stapled very securely. As far as the print quality:
-The color reproduction is very good. The colors matched the file I provided, and the saturation and vividness are excellent. Neither over- nor under-saturated.
-The blacks are truly black, the white truly white. Overall, contrast is excellent.
-Detail sharpness is average. On extremely close inspection I can make out a bit of fuzziness in the details, but this is to be expected from a file that was up-res’ed. And in any case no one viewing the print on a wall will get close enough to see the level of detail that I was inspecting. No complaints here.
-Like nearly all canvas prints I’ve seen, the print reflects a moderate amount of glare light, so care must be taken in regard to where the canvas is hung to avoid glare light. But again, this is common for canvas prints.
So there you have it, that’s my review! This canvas will hang proudly on my studio wall. Good job Zaza!

Photo of the Day, June 9, 2010: “Sliding Sands”
Wednesday, June 9th, 2010
Today’s photo was taken inside the crater at the summit of Haleakala, one of the inactive volcanoes in Hawaii, elevation approximately 10,100 ft. It was a landscape like I’d never seen.
I couldn’t come up with a good name for today’s photo, so I originally called it “Alien Land”, but that was a totally lame name. I was just informed that the trail I’ve photographed here is the Sliding Sands trail in the Haleakala crater, and that is a much better name. So this photo is now called “Sliding Sands.”
Happy hump day, everyone!
-Chris
