No. The problem is that silver particles in classic b&w materials blocks IR light so resulting picture which is used later as a mask to deduct flaws removes not only dust and scratches but also information from the photo. The same applies to Kodachrome slide film. > Is there any good reason for doing a direct B&W scan instead of color scan > of B&W film? > If so, how do you manage scratches and despeckling? Manual clone tool? > Other? Dust can be removed to some extent only with a good blower/brush. There is no way to remove scratches this way of course. Dust and scratches are less visible when scanning using scanners with more diffused light - either Minoltas or the latest Nikons. -- Balance is the ultimate good... Best Regards Sylwek
