RE: Dead Tree from Yellow Springs
On an SLR film camera there used to a red dot out of alignment to the normal focusing point (on the barrel of the lens) for the correct focusing point when using IR film. Is the focus point the same on a DSLR for normal and IR photography?
I also look forward to see what you did to a DSLR to make it shoot in IR.
The focus is sometimes different with different lenses. Hard to tell cuz different lenses have different coatings that react differently to ir. The only thing that really needs to be done is that the ir filter on the sensor is taken off.
That sounds like a permanent mod.
Just cleaning my sensor makes me nervous.
