I do have to take pictures in a low light environment, where part of the assignment is to capture the naturally present light. (its a chill-lounge sauna) I could get higher ISO, and wider aperture, but I need to get as high quality as possible images with as much depth of field as needed.
My squestion is: Is it possible to take 2 shots, one with a long shutter speed to get the lighting and the color and whatsoever, and then an identical shot with low shutter speed and a flash, and combine those afterwards? sorf of like a frequency separation, but taking the color from one shot, and the structure from the other? Would the resulting image be any good?
