Hello everyone,
I came across this interesting forum and just decided to ask for some opinions from the more experienced ones in the field.
Recently I've accepted a challenge of preparing b&w photos for large printing (for exhibition purposes). The material I have is mainly glass negatives (from 1930's) along with some glass positives and film negatives. The scanner I use is Umax Astra 4450 (with Vistascan software) and I started to scan them in b&w 16-bit mode, 1600 dpi which I suppose is enough for printing the images in app 50x70 cm sizes (is it?). My problem is that every image seem to have diagonal parallel stripes which are particularly visible on the uniform part of the photo (such as the cloudless sky for example) (in attachment). The stripes are not visible when I scan them in 8-bit mode but I'm affraid that limits editing process which is particularly needed for some poor, quite faded negatives. Did anyone come across similar effect, what seems to be the reason for it and how should I avoid it?
Many thanks in advance,
Zana
