A masking frame, also known as an enlarging easel, is an adjustable frame used to hold photographic printing paper securely in position under an enlarger. It allows precise alignment, accurate cropping, and consistent margins when producing prints in the darkroom.
Understanding masking frames is essential for photographers working with traditional film and darkroom printing. They provide control over composition, protect paper from light leaks, and ensure clean, professional-quality prints, making them a vital tool for fine art and technical photographic work.
