Hi folks, I have some expired Orwo films I am going to start working my way through, expired anywhere between 1966(!) and 1993. I've got some Calbe R09 and Orwo/Calbe A49, and Kodak HC110. Question is - what to use to develop these films? The Orwo/Calbe chemistry is the recommended developer, and developing times are available. HC110 slightly harder to find times for but from Googling, I have (I think) an idea where to to start. HC110 seems (also from Googling) to be the developer of choice in order to minimise fog - so looking for opinions on whether I should use this, or develop in 1+40 R09 - or 1+100 stand development. Going to develop a 1993-expired film tomorrow - opinions welcome!
