I've always wondered how many pixel do you need to have the picture quality comparable to film (I mean just the details in the picture.)
I think I've read somewhere that 25MP is an estimate for 35mm film so 39MP sounds about right for large format.
Does anybody know a good MP number equivalent to film?
You will find many websites debating this issue and to be honest some are very misleading. Many so called "experts" try to justify the numbers (pixel counts) so as not to be left behind and considered otherwise.
When comparing film to digital there are many aspects that need to be evaluated, from the click of a shutter to the final image there many stages and each as important as the other. Two different digital cameras from two different makers can produce different results, similar could be the case with two film cameras even though there are many similarities. When it comes to comparing film vs digital the cameras and the picture taking process are not similar. MP has more to do with what you wish to achieve in terms of size (final printed result) rather than to do with quality. Two different sensors from two different makers, software to program the sensor, accuracy of exposure, white balance all can render different results.
Take for instance the Nikon D70s, this camera is actually programmed in a way to under expose. The idea behind this philosophy is that a slightly under exposed image can have greater detail than a slightly over exposed one. There are advantages to this philosophy, digital is not good in handling overexposure just like slide film. The disadvantage to this is that many are not pleased with not perfect out of the box shots. The Nikon D50 on the other hand is vibrant in picture taking, however, it losses out in sharpness of the overall image to D70s. Which one would you prefer?
My personal opinion and bottom line: If one is content with print sizes upto 10x12 a good D-SLR of 6 MP is more than sufficient for anyone. If you wish to print posters of every image you create, you need the 39 MP Hasselblad
Let me provide a link for you to refer to which actually relates to a 39 MP camera
