Which sequence correctly represents the order of developing photographs?

• A. Stop Bath, Developer, Fixer, Wash
• B. Wash, Developer, Stop Bath, Fixer
• C. Developer, Stop Bath, Fixer, Wash
• D. Developer, Fixer, Stop Bath, Wash

Answer: (C)

In developing photographs, you control a sequence of chemical reactions to create a stable image. First, the developer reduces the exposed silver halide crystals to metallic silver, forming the visible image and setting its darkness and detail. Next, a stop bath halts any further development by neutralizing or deactivating the developer, so the image doesn’t keep changing. Then the fixer removes the remaining unexposed silver halide crystals, making the image insensitive to light and permanently fixed. Finally, a wash rinses away all remaining chemicals to prevent future deterioration.

This order works best because stopping development before fixation prevents ongoing changes that could blur or darken the image, and washing only after fixation ensures all residual chemicals are removed without risking further alteration of the image.
