I just started to shoot B/W from color on medium format. I added some top of the line B+W Schneider B/W filters. I used Tmax 100 developed in a pro lab in Xtol. I think I noticed that the sharpness when using the orange filter is not as good than without a filter. I'm looking at the results by scanning on a flatbed.
Should I expect a loss in sharpness?
sharpness is a combination of contrast and resolution.a clean filter won't affect eitherbutsometimes.filters can pick up a little surface fog,affectingimagecontrast.just make sure your filters are really cleanbefore using them.mine fog up from being kept in foam-padded jewlery containers and need occasional cleaningwith glass cleaner.
