Can you use filters from film cameras for DSLR's? Or old camera's on new camera's? Or i suppose the more important question im meaning to ask is, will it harm my camera? The reason why i ask is because I was going through my parents old photography stuff as they said i could sell it and use the money to put towards a lens or other camera accessory, anyway, i came across a bunch of filters that it looked like my dad had bought i guess on sale but otherwise like new. I was going through them to see what type they were so i could make a list of all the stuff and see what they would go for(if anything that is), it didn't even cross my mind that they may fit my current camera until my dad suggested that i tried them on just for the heck of it. At first i was totally opposed to it because my camera is a DSLR, and the filters are meant for a film camera, and also i doubted that they would fit,and obviously i didn't want him to wreck my new camera but then my dad started putting it on and showed me and i was some what amazed. After thinking about it somemore i sort of doubt that it would harm my camera but at the same time, you could probably do all the stuff with the filters on photoshop but the fact that they have it already done and just some of the different ones are kind of cool. I don't know how practical(for example, when would you use a tinted green filter? or a tinted yellow and purple filter aside from the fact that it looks sort of cool, like why would you need to add that to your picture?) they would be as they're meant for B&W film photography but they're kind of cool to play around none the less. Sorry this was probably a compeltely newbie question, but hell, that's what i am. i am just getting into the DSLR world and just wanted make sure! There's about 7 filters out of about 15 that actually fit my camera and they were made for Nikon, just not for a DSLR Nikon or even a film camera that was made in the last 10 years! Thank you for being patient and answering my many 'newbish' questions.
