Nikon has announced their newest pro body, the D3s, and it’s quite an update if you ask me. Lots of ISO (up to ISO 102400), movie recording, a self cleaning sensor, a new 1.2x crop mode and a quite shooting mode top out the list of new features.
That said, the big news from the D3S is high ISO performance. The D3s expands the base sensitivity of the sensor a full stop on the top end, from ISO 6400 to ISO 12800. Further in addition to the normal H1 and H2 expanded modes, Nikon has added an H3 expanded mode equivalent to ISO 104,200.
While there isn’t much to go on yet, the fact that Nikon felt comfortable expanding the expanded range form 2 to 3 stops may say a lot about the sensor’s performance. At least if H3 isn’t just a bullet point to gain some photographic bragging rights.
It seems that you’re looking for updated Spyder3 colorimeter software. A lot has changed since 2009 when this article was originally published, perhaps most importantly is that there is even more powerful and fully featured color management software available now. Even better it’s free, and open source. If you’re interested, you can read through my guide to getting started with DisplayCal and ArgyllCMS.
If you use a Spyder 3 Pro or Elite and don’t have the Spyder Utility set to auto update, there is a new version (3.1.2) of the Spyder Utility to introduces several improvements to the UI as well as fixing some annoying bugs I was experiencing in the previous version. The new version also introduces two new calibration targets for default CRT and LCD luminance levels.
I recommended disabling your anit-virus software when you install the Spyder Utility. I had problems when installing while either Kaspersky or Avast were running causing the software to take forever to install. Temporarily disablingthe AV software, and the install was done in maybe a minute tops.

I have a whole new level of respect for the people who flew in these things–B-17 Flying Fortresses–in World War II. They are cramped, hot, there’s not a whole lot of room to move around, and with 13- .50 cal machine guns firing over the sound of the engines it would have been very loud. In fact, when they fired up the engines alone it was a very impressive. This time we have some shots from inside the Liberty Belle.
Hot inside, would be an understatement; by the time I got a chance to crawl around in it, the plane had been sitting on the tarmac under the glorious South Florida sun for something like 4 hours. It was probably close to 120 degrees, or more, inside the plane and there is very little in the way of ventilation. At least they had the bomb bay open and a perspex panel from the roof removed. Not that it helped very much.
It war time, it was probably only marginally better in the air until they got to cruise level, at which point it would be very cold.
I can also say I very much wouldn’t want to be in one of these things when they started shooting at you. There’s very little room to move, though it’s hard to tell from the photographs since they were shot at 10mm. Getting to the nose from the tail door involved crawling over a 1 foot wide catwalk in the bomb bay then though a small crawl space under the cockpit. Even then, once you’d reached the nose getting to the bombardier’s stool at the bomb site was nothing short of gymnastics, for me at least. To get to the tail gun required crawling though the smallest part of the fuselage around the tail gear. The belly turret was claustrophobia inducing just looking at, I can’t imagine what it would have been like sitting in one with your knees by your ears, for 8 hours.
Cramped, hot and yet so awesome.

Had to go out this morning to pick some stuff up and I decided that since I was going to be in the area, I’d stop by Wakodahatchee and Green Cay and see how things were going, especially since I’ve been seeing more and more birds around the house.
To make a long story short, there wasn’t a lot of activity at either site. Bird populations were dominated by juvenile Common Moorhens and Boat-tailed Grackles. Other than that there were some cattle egrets at Wakodahatchee on the island in the first pond if you turn left on the boardwalk. There were also some numbers of Mottled Ducks and Black-bellied Whistling Ducks; not a lot mind you, but a few more than I remember seeing this time last year.
One disappointing change of note, at Wakodahatchee they have put up a chain link fence–probably due to alligator related concerns–along the south side of the northern most walkway (the concrete one on the berm). Unfortunately, they’ve placed it far enough away from the existing fence that it pretty much ruins shots into the pond there (there are a couple of clearings) for anything that’s closer than about 10-20 feet out.
I was fortunate enough to have the opportunity to photograph the Liberty Belle, one of the 15 remaining Boeing B-17 bombers that is still flying, when it visited Fort Lauderdale’s Executive Airport this last weekend. Awesome, would be a good way to describe it.
A bit of history; On September 9, 1944 the 390th Bomb Group sent 12 aircraft to take part in a bombing raid on Dusseldorf, Germany. Over the target, one plane was hit in the bomb bay by flack, detonating the 1000 pound bombs it was carrying and destroying or knocking out of formation 9 of the 12 aircraft in the squadron. Six of those went down over the target, 2 flew on a single engine and landed in Paris, one made it to Belgium. The lone damaged plane to make it back to its home base was the Liberty Belle. After that raid, the Liberty Belle went on to complete 64 more combat missions before being salvaged.
Well it seems the rumor mill was right on this one. Canon’s first announcement for the fall season was the EOS 7D as expected. With an 18 megapixel sensor stuffed into Canon’s 22.3mm x 14.9mm APS-C format, the 7D promises to be a bit noisy, if only from the 8 frame per second motor drive.
However, as un-compelling as I thought the 7D would turn out, mostly due to cramming more pixels in an already small sensor, it carries some interesting improvements over the EOS 50D. Even more so, in terms of the user interface and customization options, the 7D looks like an improvement over all of Canon’s camera’s to date.
19 point autofocus system
±3 stop metering range for exposure and flash exposure compensation
ISO 100-6400 native, ISO 50-25600 expanded
Transparent LCD in viewfinder to display AF points and grid lines
E-TTL II commander mode
The EOS 7D supports the same ISO expansion options as the EOS 5D mark 2, specifically 2 stops over and 1 stop under the native range. That is a native ISO range is between ISO 100 and ISO 6400 in 1/3rd, 1/2 and full stop increments. In addition, ISO 50, ISO 12800 and ISO 25600 expanded settings are provided.
The 7D’s exposure meter now supports the same ±3 stop range of exposure compensation as seen in the EOS 1 bodies, something that’s not found even in the 5D Mark 2.
A few days ago the specs were leaked for the next Canon small format camera, the EOS 7D. Since then the rumor mills have been running rampant with the news. What raised some concern for me was that the camera would carry an 18 megapixel APS-C sensor. More pixels in a tiny sensor does not bode well for noise.
However, I’ve been saying for quite some time, that Canon’s solution to the pixel problem was simple, make the sensor bigger. Their APS-C format sensors measure 22.2 x 14.8mm, 1 to 1.4mm smaller than the APS-C format sensors in Nikon, Pentax and Sony cameras. It stands to reason that if you want to keep increasing the resolution and you can’t make the pixels incredibly more efficient, you just make the sensor bigger.
On the efficiency side, Canon reached the limit for micro lens size with the 50D and its gapless lenses. That rules out one possible mechanism for improvements. Making the sensor more efficient is another, and Canon seems to make progress here each generation, though it’s almost never revolutionary.
That leaves increasing the sensor size. The question isn’t so much can EF-S lenses support it; it’s clear from looking at images of adapted EF-S lenses that their image circle can usually cover a 1.3x APS-H sensor, something in the 1.5x range shouldn’t be a problem. The real question is can the mount support it.
In that vein I’ve done some quick measurements of the 2 EF-S lenses I have access to and it seems that the rear element protrudes ~10.16mm from the front surface of the lens mount.
Turning things around, the front edge of the mirror on the Rebel XTi in the up position, rests about 10.16mm behind the front surface of the lens mount, equal to that of the EF-S lenses measured. However, the front edge of the mirror on the 40D sits further back, at about 11.5mm. That seems to indicate that there is at least a 1.3mm margin to increase the depth of the mirror box (or at least the size of the mirror) with out interfering with the use of EF-S lenses.
Now the question is how big of a sensor does that result in and is the resolution consistent with the published rumors of the 7D?
If we figure the sensor can increase in size by 1.3mm in both directions, it will measure 23.5 x 16.1mm. If we keep the same 5.6 micron pixel size from the 50D we end up with a ~18 million pixel sensor.
Tangentially, it also occurs to me that the 7D is also a branding change. Presently the non entry-level APS-C 1.6x cameras are branded in the x0D range, which is very much what the 7D looks like. There’s still room to continue that numbering scheme for at least 4 generations. However a departure in sensor size may warrant a departure in naming as well.
So while it’s still a rumor, a larger sensor in the APS-C 1.5x format at 18 million pixels seems to hold up under some back of the envelope scrutiny. Will Canon take this approach? That remains to be seen, but with the expected announcement coming in just a couple of days, we don’t have long to wonder.
Today for me has been spent mostly writing code, not my favorite pastime, and tomorrow looks like more of the same. I did, however make it a point to fire up Lightroom to play a bit more with DFine2, a rather nifty looking noise reduction “plug-in” for LR.
As clean as my mark 3‘s image are, there are times when I want to push the image further than I probably should or want to get as much out of a high ISO shot as possible. Either way my quest for that, and a healthy desire to keep as much of my work-flow in Lightroom, lead me to DFine 2 from Nik Software, which advertises itself as a Lightroom plug-in.
“Plug-in”, that may be what Adobe calls it, and by extension Nik Software, however I don’t know if I’d call requiring a full export to TIFF to a mostly stand alone program a “plug in”. Generally I think of plug-ins as something that adds functionality from inside of the program it’s plugged into.
That got me thinking, a while back I started a Lightroom 3 wish list and adding “real plug-ins” to it seems like just time time to post something about it.
My mom is in the slow process of redecorating her movie room; she’s decided she wants to hang “snack bar” posters reminiscent of what you might expect at an old time theater snack bar. What that means, as both photographer and son, the task more or less ends up to me to design and create the images. Not that I mind.
The concept I was presented with was to have a series of images of various foods, pop corn, soda, candy, that are styled as snack bar ads. Following that I’m envisioning capturing the elements that most evoke. Each image will carry a theme and color-scheme complementary to both the overall theme and the subject in each image.
I’m starting with the pop-corn poster, which I envision will look like the concept sketch to the right (no, drawing isn’t my strong suit). The subject matter is dominated by yellows, reds and white, so I’m thinking I’ll work with that color pallet for the image I’ll complement and accentuate the red stripes on the popcorn containers with a red background. Tint my main light to warm up the yellows in the popcorn. I think, red and yellow will also work well as popcorn is suppose to be warm and buttery (also yellow) and red and yellow carry that connotation as well.
I’ve broken the image into it’s 3 key layers. For the foreground, I’m thinking out of focus popcorn to frame the main scene and evoke a bit of the feel of a popcorn machine. The main scene will be two popcorn cartons overflowing in a sea of popcorn. Finely the background will be a nice red gradient falling off as it progresses away from the scene.
I’m expecting the real challenge to be lighting this. I’ll be working with only 2 speedlites and not much to go by in the way of proper light modifiers. My overall goals are to provide even lighting without any harsh shadows, while dealing with any spill not having a proper softbox will create.
The background will be lit by a 430Ex on a light stand directly behind the scene. It will be gelled red and probably zoomed to 70mm give or take. If everything is centered right, it should give me a nice symmetrical falloff on the background giving me darker corners. Which is what I’m looking for.
The main light will be my 580Ex pulling double duty, being triggered by a pocket wizard and triggering (by way of master mode) the 430 ex slave. I’m thinking I should probably gel it between half and quarter CTO to warm up the popcorn and cartons. I’m expecting it to be slightly to camera left, and above the camera shooting though a diffusion screen. That should take care of most of the shadow issues. The rest, if necessary, will be taken care of by large fill cards on either side of the scene.
Of course the technical challenges are only compounded by the budget, of which there is none to speak of. I suspect I’ll be pulling some serious Strobist style hackery to get what needs to be done, done. Who knows maybe something creative and useful will come out of solving problems as the come up.
