Sometime last August I bought some Dev, Stop and Fix and put them in small containers like these http://www.ag-photographic.co.uk/25l-plastic-storage-container-856-p.asp. Since then I've only had time to develop a couple of films at home what with uni projects taking up all my time. While not in use they've been stored in a dark cupboard. I've had a smell and they don't smell off so i'm wondering if they'll be ok to use. I don't want to ruin my film by using them if they are. What do you think?
