Photographer's own darkroom

Photography lovers should have a fixed mode of making darkrooms in their own homes, which can be decided according to their own conditions, such as study, attic, storage room and bathroom. For a well-ventilated area of more than 3-4 square meters, just press a small exhaust fan to ventilate, nail opaque cloth on doors, windows and gaps, and do not illuminate bedrooms and darkrooms: 15w red light is used to develop black-and-white photos, and 6555W red light is used to develop color photos.
