To speed up the manual development of a radiograph, you should adjust the temperature of the chemicals to what?

Increasing the temperature of the chemicals used in the manual development of a radiograph can significantly accelerate the chemical reactions involved in the developing process. Higher temperatures reduce the time required for the film to adequately develop, as the chemical activity is enhanced. By heating the developer, the solution becomes more effective at dissolving the silver halide crystals present in the exposed film, leading to a quicker visualization of the image.

It's important to note that while increasing the temperature does speed up development, it must be done within a controlled range; excessively high temperatures can lead to overdevelopment or degradation of the film. Therefore, ensuring that the chemicals are at an optimal elevated temperature can greatly streamline the radiographic process without compromising the integrity of the final image.
