Warm places, particularly, can be more or less common based on the lighting. And commonly hot spots are a lot less recognizable with black and white. Typically, incredibly hot spots would be the worst with cameras transformed to “pure” infrared inside the 830nm-850nm array. Therefore if you receive a conversion by using a decreased number/frequency like 590nm, it is feasible you might not have complications or as quite a few issues with a presented lens. Also, chances are you'll come upon various outcomes with a “whole-spectrum” conversion.
