The May 2004 COBA meeting was held last night at the usual place and the usual time. The main focus of the meeting was taking a look at prints from various digital cameras. We wanted to see how much difference there was between 3, 4, 6, 8, and 11 megapixel cameras. Last Sunday, a number of COBA members met at Stanford University armed with a veritable arsenal of photography equipment. We tested a Canon PowerShot S30, EOS-D30, EOS-10D, EOS-1D, EOS-1Ds, EOS-1D Mark II, Nikon D100, Sigma SD9, and a Sigma SD10. Over the next couple of days, I made some prints of the images have a fairly consistent post-processing procedure.
The results were very interesting and in some ways, surprising. As expected, at 4×6, there was little difference between all of the cameras. At 8×12, the PowerShot S30 was clearly lacking compared to the DSLR’s, but its image was still acceptable to most people in the room. At 20×30, the differences between the various DSLR’s were noticeable, but as much as many people initially suspected. The biggest difference between the cameras was in color rendition. I tried my best in post-processing, but it was very difficult to get the colors to match, even in a simple daytime photo such as this one!
