I will expose a second negative when I am faced with a situation that might call for modified (plus or minus) development. This allows me to process and print one exposure, then modify development to optimize the second exposure. Many times I have found that the my first negative was good. So what do I do with the second exposure?
Instead of leaving it undeveloped, I will use it in some experiment or test that may need to be done. In many cases this is exploring the effect of plus or minus development, or trying a different developer, or a new development method, or some post-development processing, etc. This list is almost endless.
