@ Buddy, yes, the Biotar is first one
@ Richard, this Helios has more contrast - no idea how the others do, I do not find my other 2,
treatement was the same, just putting RAW in C1 and no more modification than formatting it into 900px JPeg
looking at the nice portraits, done in your initial thread, it is a clear disadvantage
my first answer was related to modification thoughts by someone with much less experience than you have,
here I thought a cheaper Helios would be a good start, as there are already some posts in the net, how to do it
