The kit I use for colour development is the Tetenal ColourTec C-41 kit, it comes with all the liquid chemicals you need, you just have to add water. Initially I was nervous about trying to develop my own C-41, however, I found it to be easier than developing black and white film. I just realised that I have not scanned most of the film that I have home processed, so here are some of my more recent shots, that I stand developed. I see that Cinestill is selling a gadget that will help with keeping the water at the right temperature, so I look to buying one at some point.
