Unless shooting in low light with a wide aperture prime. I could definitely tell you which is which But I can see what you mean.
well others have said that and proved wrong (in magazine tests and you can read it on luminous landscape).
medium format prints vs. prints from G10:
http://www.luminous-landscape.com/reviews/kidding.shtmlQuoteOver a two day period I invited photographers and local industry professionals to come to my print studio and look at a series of 13X19" prints from an Epson 3800 printer made on Ilford Gold Fiber Silk paper which were then hung side by side on my floor-standing print viewing box. This collection of seven people included experienced photographers, people from the commercial print industry, and other trade professionals. Between them there was at least 200 years of photographic industry shooting and printing experience.
In every case no one could reliably tell the difference between 13X19" prints shot with the $40,000 Hasselblad and Phase One 39 Megapixel back, and the new $500 Canon G10. In the end no one got more than 60% right, and overall the split was about 50 / 50, with no clear differentiator. In other words, no better than chance.
In fact it was the H2 system's narrower depth of field that occasionally was the only clear give-away. Some viewers eventually figured out that the prints with the narrower depth of field were from medium format, while other photographers chose the G10 images because with its wider depth of field it created an overall impression of greater sharpness.
Needless to say there was much shaking of heads and muttering. Could this be? Could a $500 digicam equal a $40,000 medium format digital system in image quality, at least in prints up to 13X19" (Super A3)?
it´s a bit like modern art experts.
they think they now modern art ... until you show them pictures painted by monkeys....
Sorry I couldnt see the bit about low light? Am i missing it?
