[HUG ] Re: tripods

Q.G.,
 
You are absolutely correct from a techincal standpoint. But I believe there is 
still a problem with comparing digital camera files to scanned negatives on a 
purely technical basis. Software must interpret what is scanned into what you 
see. I've been scanning Velvia on a Nikon 9000 for years now, and I believe 
that the color fidelity is better on my Canon DSLR than on these scanned 
images. My scanned images were about 400MB in size.
That's certainly not to say you can't get gorgeous images from a scanned 
tranny. John Gavrilis ( http://www.gavrilisphotography.com/home.html ;)produces 
stunning prints from drum scans of 4x5 and LightJet prints. So does Jim Brick ( 
http://www.visualimpressions.com ).
But I couldn't afford a drum scanner (even an Imacon drum-like scanner). So I 
have found that my DSLR images have more fidelity, contrast and better printed 
image quality than what I was able to obtain from my Nikon scanner. Since I've 
never done darkroom work, this was a more affordable option for me vs buying a 
better scanner, etc.
Just my opinion,
Bob

The more proper unit however is the pixel. The size in bytes contains info 
about how much colour/tone info could be (!) recorded per pixel.
1200 MB @ 16 bit per pixel is an image counting 629.145.600 pixels (about 
600 megapixel).
