With all the stink about megapixels lately, I thought I'd put together a quaint little test. Some of these are product shots I took for editorial clients with my 10 megapixel G7 point-and-shoot. The rest aren't my shots, but they're of similar engine parts taken with a 39 megapixels medium format Phase One P45. I read a post today where someone said they'd be happy with the 5DIII if it had at least 25 megapixels instead of 22, so apparently every last MP counts, but does it really?
And please don't cheat by looking at the exif data. I tried to erase it the best I can, but there might be some giveaways to the camera's identities nonetheless. At any rate, I've numbered each image 1-7, so try to guess which images was taken with the G7, and which one was taken by the Phase One
If you look closely enough, you can spot a difference between the G7 and Phase One images. However, I'd argue that a lot of that has to do with differences in technique. My point-and-shoot shots were taken using nothing more than natural light and some white poster board whereas the Phase One images were taken in a studio with fancier equipment. I don't know how fancy, because they aren't my shots and I wasn't there, but considering that they were commission by a rather large mega-budget corporation, it's safe to say they had the means to spend a lot more money than my editorial clients. I'll reveal who the unidentified corporation is later, but don't want to yet as it might give a clue as to which shots came from which camera.
Before anyone cries foul, is there any way I can upload the high-res files somewhere for download, if anyone cares to pixel peep? I can upload them onto my website's lightbox, but I have to invite people via e-mail.
