Hello I am quite new to photography so I apologise if this sounds like a stupid question but I cant find any info on these questions on the net. Could anyone explain the basics in the different types of films and processing? eg: What is the difference between Fujichrome and Fuji Colour Print? Why are some of these films listed as 36 exp and also as a 120 roll? What is E6 and C41 processing? I shoot mainly indoor bodybuilding competitions and have so far only used 400 and 800 Fuji Superia, had good results but when enlarged I could do with a bit sharper image any suggestions on a better film? Regards T.
