I've only had my DSLR for a few days so I am still learning digital photography. I've been digging through my old 35mm equipment and have pulled out all my old filters, do I really need them? Are the 81B and soften filters any use today when those adjustments are built into Photoshop? I know my red filter for black and white is useless but the Hoya circular polarizer does produce some nice results. What filters do you use with digital photography? Or do you just shoot Raw and add all your filter effects in post processing?
