Re: [Digital BW] What if grain is "necessary"

2002-05-10 by Truman Prevatt

That's a good point. What the scanner sees may be more akin to the 
interference patterns of the light as it interacts with the grain 
structure of the film. Maybe even some defraction frings - but those 
would be almost impossibe to see. This is part of the reason I used a 
cold light head on my enlarger.

I've built darkrooms in three different houses over the past 25 years. 
We moved about two years ago and built a new house and I was getting the 
bug to build another darkroom in the basement. My wife put her foot down 
and demanded I check into digital instead of taking up space in the 
basement. Developing film doesn't take any space and I love my RB67. I 
want to thank eveyone for their input come upto speed on the issues in 
digital photography and what scanner and printer to aquire.  What I've 
learned has made my wife very happy:-).

Thanks again.

Truman

PS Anyone interested in buying an Omega 4x5 enlarger.
