nice tutorial, I have a question though, my camera has a max iso of 1600 and a max shutter speed of 30 seconds, so I'll never be able to use a totally black filter, but do you have an idea of another filter I can use? I mean one of 720 nm for example, would that be good?
Something like the hoya R72 should work. Does the camera not have a bulb mode where you can hold the shutter open indefinitely with a remote, you have to time the shots yourself but it lets you get long exposures.
indeed, but I'm still not sure my camera is compatible with it (it's a canon 1000d). Cause I found things on the internet about an IR cut filter on some camera's and that should be removed before making IR photos... what do you know about that? I don't want to open up my camera and ruin it :S
All dSLR's have a filter inside that cuts out IR light to varying degree's. Thats what gives you the really long exposure times when you use an IR filter as basically your cutting out both kinds of light so very very little light is actually getting through so you need a long exposure. It's possible to modify the camera by removing the IR cut filter and adding one that cuts visible light then you camera operates like normal but takes IR photos.
It will work with just an IR filter and a long exposure though
