Developing photographic paper involves four primary chemical steps to turn exposed silver halide crystals into a visible, permanent image: | FullMacCrack

: Typically 60 to 90 seconds for resin-coated (RC) paper and about 2 minutes for fiber-based (FB) paper. : Typically 60 to 90 seconds for resin-coated

: 2 to 10 minutes for RC; up to 60 minutes for FB paper. DIY & High-Contrast Techniques

: An acidic solution that immediately halts the development process to prevent the paper from continuing to darken. Time : 30 seconds with gentle agitation.

: To ensure maximum black (Dmax), always develop until the image is "complete" rather than pulling it out when it "looks good".
