Matt,
You are correct, I haven't worked with MF
slide film before, only negative film (which I am comfortable with). I should state outright here that I have never done any color film development or slide enlargements/prints before. This was going to be my "first time" giving it a shot on my own. So go easy.
I have a roll or two of 6x6 Velvia and Provia that I will be developing soon. My assumption when I bought and shot the film was that MF slides were like 35mm slides and needed to be mounted for a multitude of reasons (storage, projection, enlargement). So I was planning on buying 6x6 slide mounts but thought I should ask about it first since I couldn't find much about the topic of mounting MF slides.
Once I had the transparencies finished and protected/mounted I was going to research what I needed to make color enlargements, which is what you're referring to as Ilfochrome. Correct? Enlarging and printing from color slides is starting to sound extremely daunting though.
It sounds as if at the least I should purchase sleeves and filing pages and then only use slide mounts for the ones I want to project.
