Hello,
When I started with collodium (in 2018) I began to build my own DIY mobile darkroom.
Made of a 33 liters black plastic storage box, some wooden plates, a pice of red plast and a color light (12V LED).Interior dimensions are aprox. 25x35x30cm.Weight 5 kilos.
It works with collodium max. 4x5 inch.With traditional b&w-work up to 5x7inch (2 baths only).
I use it also to load the filmholderes with film and photographic papers, to load the 35 filmcanisters with bulk film.

Sounds nice; looking forward to the pictures. Also interested in how you solved the challenge of getting your hands into the box without allowing light in.

Edit: thanks for adding the images - very creative! You illustrate aptly that it doesn't take a complicated, high-tech approach to just get the job done in a basic manner.

Quite cool, thank you for sharing it.

Now you've got me wondering how compact one could make an enlarger...

Thanks for your feedback! Your question about the dimensions of an enlarger points out that my term "darkroom" isn't quite accurate. It should perhaps be called a "dark photographic box," unless that term is already taken.
