When working with film strips it can often happen that you accidentally touch the emulsion side of the film. The damage often is irreparable. You can avoid damages to the film material and comfortably insert film strips into the scanner or film holder by wearing fine cotton gloves.
Anti-dust spray is used to clean film material - no matter if it's mounted slides or film strips - by removing dust and fluffs with a flimsy current of air without touching the film material at all. There is no better, more comfortable and more efficient way to clean your film material.
For working with single negatives or positives we highly recommend using tweezers, because otherwise you run the risk of touching and damaging the film.
If you work with digital images - no matter if they come from a digital camera or from a film scanner - you should calibrate your screen. Without a screen calibration performed with objective criteria you run the risk of wrongly adjusting the settings of the scan or the image editing software, which makes the image look right on your screen, but will cause unnatural alienated colours on other output devices (printer, image service, new screen).
