Final answer:
Knowing how to process film manually is important because it gives photographers control over the final result and allows for experimentation and creative expression. It is also a valuable skill to have in case of equipment failure or when working with older cameras.
Step-by-step explanation:
Knowing how to process film manually is still important even with the availability of automatic processors because it helps photographers have a better understanding of the entire developing process and allows them to have more control over the final result. Manual processing allows photographers to adjust the development time, temperature, and chemicals used, which can affect the contrast, sharpness, and overall look of the image. It also allows for experimentation and creative expression, as different processing techniques can produce unique effects.
Additionally, manual processing is a valuable skill to have in case of equipment failure or when working with older cameras that don't have automatic processors. It is important to be able to adapt and troubleshoot in different situations.
