EOS 5D Mark II Noise Behavior
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.
