filmscanners: Re: Scanning problems



I've just had my 6x7 trannies scanned by a lab specialising in digital. I
paid for a 50MB scan and got a 7MB jpeg back. I took the CD back to the
manger, who told me that it was a 50MB scan, compressed to 7MB and that all
the information would be there when I opened it up!!! I think by this he
means that when you go to Image Size in Photoshop it does say 55MB (4800
pixels x 3900 at 300dpi), although the file is 7MB. Is this the file size if
saved to psd format? I've lent my Real World Photoshop book out. 

I explained that jpeg was a lossy compression, that information had been
lost when converting to jpeg and it was no good to me. He looked at me as if
I was mad and said that he uses jpeg for all his customers to get more
images on the CD. I argued that jpeg does loss information and drops the
colours that the eye cannot see. He told me that I had to specify tiff
otherwise he saves as jpeg, then reluctantly said 'so you want me to do the
whole job again'.

This lab specialises in digital, how can people accept jpegs? So much
information has been lost for manipulating  (levels and curves) in
Photoshop. I won't be going back there again...
