Today I discovered this little critter in a small canyon in Big Basin. The shot was taken at f/5.0, 1/60s and ISO 3200 (!). I must say I’m getting more and more impressed by the possibilities this camera enables. I read the RAW into ACR 5.2. No sharpening was applied but I set the luminance noise reduction to 50 and the color noise reduction to 25. This photo is quite usable, even though I couldn’t get the head quite sharp.
By the way, what sort of arthropode is this? Is this an albino or just a white centipede?
Yesterday I took a series of shots of the San Francisco skyline to test the noise performance of the Canon EOS 5D Mark II. The weather certainly wasn’t what you’d wish for when taking pictures. It was overcast and hazy but to allow “pixel peeping” it didn’t really matter. Just don’t expect esthetically pleasing results.
I used the 70-200mm/f4.0 L IS lens at 200mm and f5.6. The shots were taken at ISOs 50, 100, 200, 400, 800, 1600, 3200, 6400, and 12800. The camera picture setting was set to ‘faithful’. I turned off the noise reduction for high-ISO shots but I left the in-camera noise reduction for long-time exposures on.
I’ve read all the RAW files into Photoshop using ACR 5.2. Other than setting the white balance to 3100K, I did not perform any other adjustments. No noise reduction (luminance or color), no sharpening, no curves adjustment, nothing. I saved all photos as JPGs at the least deteriorating compression rate of 12 in Photoshop CS4.

After I picked up my EOS 5D Mark II yesterday, I immediately drove to San Francisco to take some photos. I was mostly curious about the noise behavior at different ISO settings. Even though I didn’t read the manual, I was able to set up the camera within minutes. I changed it to store RAW files and turned the picture mode to neutral to make sure no in-camera manipulation such as sharpening takes place.
The weather wasn’t really the best but this was all about pixel peeping, right? Other than different ISO settings and the corresponding exposure time, the settings were the same. I used a tripod and mirror lock-up.
Since I shot the photos in RAW, I performed some adjustments in Photoshop. The curves were adjusted for more contrast. The white balance was set for a cloudy sky. The photo above is sharpened at 80%, 0.3 as it appeared rather soft as it came out of the camera. I didn’t apply any sharpening to the second photo.
