C41 processing at home is easy. I use the 3 part Tetenal kit. The first step (color developer) is the only serious challenge temperature wise. The time in the color developer is short so if you get your water bath right on its not going to cause you a problem. You need to keep it at 100.4 degrees for 3:15 Thats not too hard. A big tray of water for your chemicals and your tank will do the trick. The subsequent steps can vary a bit with no harm at all. Tetenal says up to 9 degrees leeway. If you do a fair amount of C41 a Jobo CPE2 is well worth the money. Used ones go pretty cheap on ebay. If there is a downside its that the 1 liter kit is relatively expensive and the 5 liter kits might be hard to use up before they go bad.(posted 8173 days ago)As far as does it make sense to do it yourself, that you have to answer. If you are doing 35mm it may be hard to justify when you can get process only from any fast photo place for $2-3 a roll and never do any work at all! For roll film or sheet film I think it makes sense to do it yourself.
XP2 is a wonderful film. Good luck.
