    Thank you for your insight! It's important to remember that the process you describe requires a true darkoom and safelight in order to avoid exposure. Because this process is modified from the Kallitype, only dim lighting is necessary, like a single tungsten bulb placed somewhere in the room. While similar in the end result, the process you describe is quite different, being limited to precoated gelatin silver papers.

    Thank you very much! What cotton rag paper you use is largely up to you, but I recommend something that's a little bit thicker. Stonehenge White is great, and is what was used in the video. For this process you'll need 12 grams of Silver Nitrate in 75ml of water, and then once completely dissolved, add enough distilled water to make 100ml. It will probably be able to make 25 or so prints, factoring in some mistakes here and there. Hope this helps!

    Thanks! The traditional Cyanotype won't work with this process because Ferric Ammonium Citrate/Potassium Ferricyanide need UV in order to convert into new iron salts. However, I have not tested the "New" Cyanotype process, also known as Mike Ware's Cyanotype. That process uses Ferric Oxalate (also used in this process), which I believe is more light sensitive. You can do some research and some experiments, but even if it did work, exposure times would be very, very long.

    Thank you! It will also work with a tablet/laptop screen/monitor. You'll need to do some creative mounting in order to get a nice, sharp image from a laptop or monitor screen. Remember that being able to make firm adhesion creates sharpness, so a tablet would be easier.
