I go to a community film studio and it costs $12 ish to diy develop one batch of film. If you have 8 rolls you can put them all in one big tank and dev and scan them all for $12.
B&W is easier to start because it is developed at room temperature. Color needs precise temperature control. The studio has a special sink and the chemincals in a waterbath sousvide machine for color.
Film is fun I like film!
