Phillies' Clay Condrey - Action Pitching Sequence


I shot this at a Phillies game with my Canon 40D, 70-200mm f/2.8L IS back on May 8, 2009. This was a composite of 6 shots of 20 taken in high speed mode SRAW, then stitched together in Photoshop.

For reference, here's how far back we were sitting:


With the 1.6X crop factor of the Canon 40D and 200mm, you get in pretty close to the action.

X-Rite ColorChecker Passport Color Calibration System


I just received the new X-Rite ColorChecker Passport color calibration and white balance system after growing weary of eyeballing my photos' white balance for some time now.

I recently calibrated my monitor with the Pantone huey MEU101 monitor calibrator, but still spent too much time trying to find the white balance and tint to give accurate and pleasing skin tones.

So, I broke down and ordered the ColorChecker Passport. It's $100, which is a lot, and since I've only spent a couple of hours with it, I'm not yet aware of all of the ways I can use it. But, in this two hours, I was able to find out some amazing stuff... Like... My color thus far... is awful.

The first thing I did with the ColorChecker was to take it outside and shoot it at arms' length:
Straight out of camera
This is the shot exactly as it came out of my 5d Mark II and 35mm f/1.4L, with no modifications.

I then adjusted the white balance by keying off of the neutral landscape grey square, which gave me this:
White balanced with Adobe standard color
This is as far as I thought I'd have to go to get true colors. I figured, get the white balance, and use the rest of the color squares to help eyeball up my greens, blues, etc. Well, this is just the beginning. This is where I realized how little I knew about color management.

Apparently every copy of a camera and lens - and thus, combination - have different color signatures. The software can analyze a test shot containing the ColorChecker Passport, locate it within the frame, then determine the camera's response to the known colors within that environment. Doing this couldn't be easier. From Adobe Lightroom, you just export your test image through their exporter, then give the profile a name such as "Outdoors, 35mm f/1.4L before sunset". After the export is complete, you restart Lightroom, and the color profile is available for you to use for the rest of that photo shoot. The color profiles are available for use in Adobe Lightroom and Adobe Photoshop.

The results were less than subtle:
White balanced and color calibrated

Open the three test images in separate browser tabs and flip through them. You'll notice a purplish hue in my original photo, corrected in the white balanced one. The difference between the second and third shots is mainly in the blues, purples, and greens - color responses you can't correct for with standard white balance cards.

How We Roll


(View my studio site)

We might have had a little too much fun tonight.

Strobist Info:
-----------------
* Key: Alien Bees B800 studio strobe shot into Alien Bees large foldable softbox with grid, camera right.
* Fill: Nikon SB-28 speedlight shot into Westcott 43" Shoot-Through Umbrella, camera left, 1 to 1.5 stops below key, triggered by Pocket Wizard wireless flash trigger.
* Background lighting: Canon 430EX triggered by Pocket wizard, Nikon SB-26 triggered by built-in optical trigger, both at about 1.5 stops below key, pointed into white back. I used the velcro compartment separators from my camera bag as gobos on the two background flashes

Background: Savage 107" Super White Seamless Background Paper

Floor: Two sheets of white tile board, the front one overlapping the back one, which overlaps the paper.

White Paper Background/Tile Board Studio Setup


Here's a studio portrait I shot of my daughter this weekend. I recently purchased some white tile board for my studio flooring as described by Zack Arias - this was my first attempt with it. Aside from the pretty reflections under my daughter, it also helps preserve my paper background and saves some photoshopping out of creases and folds due to our walking on it.

Here's my studio (basement) when I setup the white background:


If you click the image, you'll see that I have just about every bit of equipment labeled.

Jupiter, Io, Europa, Ganymede, Callisto


** No telescope used **

This is a composite of 10 shots taken of Jupiter (Io, Europa, Ganymede, and Callisto), with my 500mm f/8 mirror lens and Canon 40D at ISO1600, f/8 (fixed), 1/6 second, showing the major four moons of Jupiter. There are at least 63 moons in all.

To avoid any vibrations in the camera, I used a tripod (w/ ballhead), cable shutter release, and mirror lock-up.

I manually focused in live view at 10X, which was tough because every touch of the lens would wobble the subject all over the place. This is such a tight zoom at 500mm that you can actually see Jupiter moving across the LCD screen. I'd then turn off live view mode, wait a few seconds to let the vibrations stop, then fire the shutter with the cable release. This just flips the mirror up, which causes a tiny amount of vibrations. I waited another couple of seconds, then fired off another cable release shutter click to take the photo.

After ten shots, I cropped the photos as close to the same spot in each photo, then stacked them all together in Lynkeos.

This is screenshot from Stellarium, showing the expected positions of the four moons at the time I took this shot.

Better to Burn Out


(This is the sun, not the moon)

View On Black

Shot while trying to capture a sunspot - I'm going to need a neutral density filter or welding glass for any luck - this was f/32, 1/8000, ISO100.

International Space Station (ISS) - Without Telescope


This might not look like much, but it's a view of the International Space Station pieced together from 19 photos taken without a telescope. I used my 500mm f/8 (fixed) catadioptric mirror lens, shooting at f/8, ISO800, 1/1500. Thanks to fyngyrz for the exposure info. It's important to realize that this is a sunlit - very bright - object, so we need the quick exposure.

The ISS travels at an average speed of 17,209 mph, completing 15.7 orbits a day. The orbit is very predictable, and using the charts at Heavens-Above, you can find out exactly when it will show up in your night sky. I was prepared for tonight's passing, having already manually focused on the moon with 10X live view, keeping the camera on tripod and pointed WSW, where tonight's transit would begin.

I found it very difficult tracking it with such a tight telephoto, keeping one eye outside the camera to help get it in my viewfinder. Once I narrowed it down, I led it by a full frame, parked the camera in the tripod's ballhead, and snapped away for the two seconds it would stay in frame before switching views to keep up. I took the cleanest shots at its peak of 57 degrees above the horizon.

I wasn't sure I had a single useable capture as I walked back from the shoot, but once I looked on the computer, I almost couldn't believe what I was seeing. A 10 megapixel photo will take up about 4 full monitors worth of screen real estate. When viewed at that full resolution, the ISS is much smaller than a fly - a little speck with three blobs - the space station and its two big solar panel arrays.

I took about 90 shots of the space station tonight, throwing away all but the best 20, then stacking (combining) them together in Lynkeos. Stacking several images of the same shot helps remove the random noise due to atmospheric distortion. After enlarging and correcting the white balance, this is the final result. Take a look at one of the raw shots to see what I mean - and keep in mind that I'm zoomed in at an effective 800mm (500mm x 1.6 crop factor) and the crop of just the space station.

Here's a tight crop of one of the unprocessed images to show what a difference the image stacking makes:
