I recently bought an accessory adapter and a Hoya R72 filter for my Canon G3, so that I could do some infrared photography. This is “near IR” photography, the kind where things look weird
not thermal infrared, where you can see how hot things are:
The filter cuts down the amount of light by a pretty huge amount – I went from a 400th of a second down to around a 4th of a second on an outdoor scene.
The results were as I expected (weird and very red), but I’m looking for some advice on subjects.
