First, thank you so much for the ideas and suggestions. I was pondering my need for a darkroom and came up with a notion that should work in my classroom. But I was wondering if anyone could answer the following:
The use of paper negatives might be the easiest starting point. I was thinking of making up changing boxes, instead of changing bags. I would make one for students to load the paper into their cameras, and another for them to process their paper negatives. I was wondering if I could place a window into each of these boxes so that my students can see what they were doing. Could I cut out a window in the changing box and then use a red safelight filter (think of it like a car's sunroof) without harm to the paper? Also could I use a battery powered closet light with a similar red filter to add some light into the same boxes for better viewing? I would also cut out arm holes into the changing box and attach the sleeves from a cheap changing bag. Is there some other way to make up these sleeves at a lower cost? I was thinking about using the legs from old jeans and sewing some elastic on the pant cuffs. As I am thinking about this, I would like to use everyday items and show student how they were constructed this way they can (if they wish) be able to try this out in their home. And since I also teach an environmental science course it would be a nice way to show reusing of materials. If this works out it would be great. And would gladly post this information on my site for others to use and improve upon. Thanks again for the assistance. Chris
