This little section just has to be here. If you are interested in your camera at all - even for just family pictures - there is no reason to try for anything but the best possible quality of results. That applies to trade processing too. It has to be said that some processing firms - not always the cheapest - are not good at quality control. Find one that is, then stick to them. Always hold the camera still, take care with focusing and buy good quality fresh film. Some of the stuff you see in shop windows on holiday looks ancient - check the expiry date on the carton. Correctly stored film will last long after it's display date, poorly stored will not. All of my film, except for the stock in my bag, is kept in a polythene bag in the fridge. Film should never be allowed to get too warm or damp. Have the film processed as soon after exposure as possible, or do it yourself. When in the darkroom, take great care to prevent any dust from being on the negatives. Clean the enlarger lens, condensers and negative stage regularly, and focus accurately. I use a focusing aid - a thing like a little microscope - only a few pounds but a very great help. Get the enlarging exposure right using a meter or test strips. If you don't know what a good print should look like, visit some exhibitions, or join the local camera club. Mono prints should show a full range of tones, from a dense black at one end - not a brown/black - and a pure white at the other. Nothing looks worse than a 'muddy' print, and, if you had to snatch the print from the developer because it was going too dark, then it was over exposed under the enlarger and is no good.
