I'm afraid I may have buffooned myself again. I just developed some film using D-76. The film came out with no images on it - it is just a clear strip of film. Could this have happened from light getting to the film when I was loading it in the canister? Or.... I'm trying to think...a dark object causes a transparency in the negative and a lot of light causes the more opaque part of the negative. Using this logic, I am thinking that it is possible that no light at all reached this film. If I somehow got mixed up and tried to develop an unexposed roll of film, would/could this be the outcome? I'm using 120 roll film and I remember putting black tape on a roll because it had become "undone." Then, a few weeks passed and I guess I thought it was exposed but I was not 100% sure the night I put it in the canister because I was in an inpatient mood and there was a huge storm going on and I was tired. The other possibility is that I mixed the D-76 several weeks ago but stored it in a plastic bottle. Of course, there was air in the bottle and I have come to understand that plastic will "breath" to some extent. If the D-76 went bad, became exhausted, could this be the reason for my outcome? Also, after I loaded the film in the canister, I did not develop the film right away. I waited about a week.
