You can load and develope under a red safe light. I buy aristo ortho from freestyle in calif. I teach large format photography and shoot 4x5 commercially and have done so for ten years and use many different films at different times and at the same time. So it is important that the information that the notches provide by readily available. I use a changing bag to load film.
Some guys also run the shower a little to reduce static.
In a separate room, I blast all the holders and darkslides with canned air, insert the darkslides, and put them into a new ziplock bag immediately. After loading, each sheet gets double-checked to ensure the emulsion side is up and the film is pushed into the holder as far as possible. Using this method, I so far have no dust problems. The darkslides are black on both sides, so every speck of dust is easily visible. 2. turn on shower to the hottest water possible for three to five min.
