Aren't there different IR kits specifically tuned to B/W, color and high color?
I don't know.
I do know you can use a filter on any digi camera, but these are so dark I think you might need using a tripod. My camera is a complete conversion with hot mirror replaced by a clear (or blue?) filter, this is next to the sensor so not visible from the front of the camera.
The camera's own setting have a choice of color or sepia or black and white.
What filter did they use for your camera conversion, if the cut-off is 830nm you will not be able to get the same result as it ill most probably be BnW IR.
They used a 720nm with mine.
I have the black and white, the sepia and the color, though the 'color' is all reds and pinks/magentas before I use a photoshop action which swaps and changes the red and blue channels. (I think?).
This shot is after the ps 'action'. Not so varied colors like realafan.
