My first experience with shooting reversal film (as it was called "back in the day") wasn't even with a 35 mm camera; when I was in the Navy from 1951 til 1955, I had a dinky little range finder camera that used "828" film; it came back mounted in regular cardboard mounts; it did a pretty good job at the time. After I got out of the Navy I got a 35mm SLR camera, a "Topcon"; it did a great job with Kodachrome; ( which was ASA 10 back then )
I hated to wait for Kodachrome to be processed, so I started shooting Anscochrome; you bought a "kit", which made up enough solution to process ( I think ), about 5 or 6 thirty six exposure rolls. I processed the Anscochrome one cassette at a time, in a small "daylight" tank made by Leitz. At that point in time, color film was only about half of the market; a lot of people still shot black & white almost all of the time. ( everyone had a dark room "back then" ) A great (and very popular) fine grain B&W film was Kodak's Panatomc X ; It was a negative film, and almost everyone developed it as a negative; however, you could buy Kodak's "direct positive" chemical kit, and develop it as a "positive", and the resulting slides were absolutely tack sharp !
I still have a few laying about somewhere. It was almost the same process as processing Anscochrome, only fewer steps and you didn't have to "reexpose" it with a photo flood, and it produced fabulous B&W slides!
During most of the 90's I was shooting with a grand old Canon F-1; ( the F-1 body and the 200mm / f 2.8 lens that I bought used from a local camera store were "loaned" by Canon USA to professional photographers who covered the winter Olympics that were held in Lake Placid, N.Y., then returned to Canon, were "refurbished" and sold at a great price by "selected" camera stores; the whole time I used the F-1 I was still shooting Kodak products. After taking an "all expenses paid" trip to Oahu, and spending three months shooting with my old Canon F-1, ( and part of the time with my son's new Nikon F-5, ( and all Fuji Velvia ), I "saw the light" and bought myself a Nikon F-5 when I returned home. I still have the F-5, and it still "works" as well as it ever did, (and I know that there are still many people shooting Fujichrome films to this day, but I doubt if I'll ever even buy another roll of film. )
I will say this though; I learned a lot about exposure, etc, while I was still shooting 35mm "slide film", and I STILL use much of what I learned while I'm shooting digital; another BIG pus I have...........for years and years, you focused camera lenses with the focusing "ring"......(with your fingers !) I still have a manual focus 105mm Micro Nikkor, a superlative MF
300mm / f4 tele, plus about two or three more old Nikkor MF
lenses; and thanks to Nikon's wise decision NOT to change their lens mounts, I still use all of these with my D 300s; auto focus is fantastic for many things ! And manual focus is still even better for certain other things !
Storage of color slides...............(I can't believe so many people have problems with mold ! ) I have all slides stored in ordinary, inexpensive metal slide boxes, which are in vacuum sealed "space bags" (with desiccant in each bag) cold temperature doesn't hurt slides; hot temperature KILLS them ! ( and moisture kills them even faster )
BTW..........if you transport ANYTHING in the wintertime, and it gets real cold, ( slides, cameras, lenses, electronics, ANYTHING ) don't bring it into a warm house, motel, whatever; anything that's cold, (especially if it's metal, glass or electronics) will cause the moisture that's in the warm air to condense on the cold surfaces; this can and WILL kill lots of things; (and it's easy to avoid) I always carry zip-lock storage bags.........stick the item into the bag while it's still cold, press out as much air as possible, and zip it up; ( I sometimes even stick some duct tape over the zip end ) then take it inside, stick it under a table in a corner, and leave the thing sit for 3, 4 hours, (or as long as it takes for the contents to warm up to room temperature; THEN take it out; ( it's NOT the cold air outside that does the dirty work, it's the warm, moisture laden air inside, that always condenses when it comes in contact with cold surfaces. ( basic 7th grade physics )
That's a few of my experiences with slides.
