The Luminous Landscape have published an article called 'Measuring Megabytes' in which Chris Sanderson, Michael Reichmann, Charles Cramer, Bill Atkinson have produced photographs using a range of high end digital SLRs, medium format digital backs and 4x5 medium format film. The medium format backs were from Phase One and included the P25, P30 and P45 which have resolutions of 22, 31 and 39 megapixels respectively. The digital SLRs used were the 16.6 megapixel Canon EOS 1Ds Mark II, 12.7 megapixel Canon EOS 5D and the 11 megapixel Canon EOS 1Ds. The results of the shoot will be of interest to anyone who has questions about how resolution affects the results of your work and on the differences between the different types of equipment. The results are also being published on a DVD which will include Raw files from the shoot and scans from the film produced. The article can be accessed here.
