In terms of filters I currently only use a polarizer and a .6 ND filter (and of coarse a UV filter to protect my lens). I can see how others could be needed though; my normal method for correcting for bad lighting/ incorrect temperature is a slight overexposure to ensure all the color layers are exposed, anything else is fixed on the computer. Obviously overexposing is not possible with slides.
