Very nice. Is that a IR Converted Canon EOS 650D, or an infrared filter? (R72 or similar)

Very nice. Is that a IR Converted Canon EOS 650D, or an infrared filter? (R72 or similar) Thanks Fen, it's a converted camera. I do still have an R72 filter but modern digital cameras appear to have such effective IR cut filters that the exposure times get ridiculous - or at least more ridiculous than I am prepared to bother with...  Best non converted camera I have for IR is an old Nikon D50 which has a really weak filter. With the R72 it gave around 2-3 seconds at F8 & ISO400in reasonable sunlight, indeed the filter is so poor some shadows and black materials have distinctly brown cast when used normally...  |

Didn't the Leica M8 have a similar pronblem? iirc they had to send out special filters to owners of it.

My old K100d is apparently fairly similar to the D50, I've been able to shoot hand held IR with it but it's IR sensitivity isn't so great that it noticeably affects normal photography. Colour shifts are quite common with my full spectrum converted models, with these external hot mirrors are useful for reversing the conversion when desired. They have many advantages for IR: allowing combinations of IR, visual & UV: fast shutter speeds without shooting wide open... |
