Both the brother and I took colour slides as well - Kodachrome was the #1 film of choice, since Kodak did the processing and sent you back the slides in their iconic little yellow box. Ektachrome was another Kodak product but was purchased without processing included, so you had the option of doing it yourself. Then Cibachrome came along which allowed you to make colour prints from your slides - The Brother was a big Cibachrome user, me less so.
I came across this snap the other day - I think to be fair it was The Brother's. Both him and I worked in photographic stores (different ones) during our teenage years and at some point he must have pointed his camera (loaded with Kodachrome) at a shelf and this was captured for posterity:
I can't see myself going back to processing my own colour film but I can maybe - just maybe - see myself using colour slide film again. There is something very special about the colour you get from slide film - as I hope to show here once I get some more scanning done.
