When developing my B & W film , I first cool my developer to 68F. Then when I pour it into my tank and develope it.As I develope the film it warms up to the ambient temperature,frequently as high as 75 F. I can think fo three techniques to handle this.

Howard, I use a presoak at the same temperature as my developer. This brings the tank to the correct temperature and helps to ensure even development. I soak the film for 1-2 minutes--no more.

The other important step is I keep the film during the entire developing stage in a water bath, which is set to the developer temperature. I use a large enough container to ensure that it will not fluctuate during the development cycle.

If you follow these steps, you should achieve consistency.
