Photographic Filters – The Ins and Outs
In the good old days of film photography the only way to achieve many effects on your photos was with the use of specialized glass (or plastic) filters, fitted to the front (or in some cases slotted into the rear) of camera lenses prior to taking the photo. Fortunately in the modern digital world some of these filters are still used and while many of the old effects can be reproduced in a digital darkroom, others still require the photographer to do the work prior to post processing.
