What might a fading image in manual processing suggest?

A fading image in manual processing typically suggests inadequate fixing time. The fixing stage in film processing is crucial as it removes unexposed silver halide crystals from the film, which allows for a clear, stable image. If the film is not fixed for long enough, residual silver halide can remain on the film, leading to a decrease in image density and causing the image to appear faded or washed out.

Inadequate fixing does not provide the necessary conditions for the emulsion to reach full clarity, which eventually impacts the longevity and quality of the radiographic image. Properly fixed images are stable and can be viewed without further deterioration, highlighting the importance of this step in the processing sequence.
