I bought a Yashica 44 LM and got a few rolls of outdated film along with the camera. One of them is Ilford HP4. That's all good, but the problem is that I have no clue of how long I should develop it? I only have HC-110 and ID-11 available. Can anyone recommend developing times for this film with one of these chemicals? I'm not looking for advise on wether or not to use it, 'cause I certainly am gonna try just for the fun of it!
