I use TMY 400 in both roll film and 4X5. With roll film it seems I have to aggressively agitate during development. I am considering tray development with 4X5 but can't see how I can aggressively agitate when using a tray. Is a 5X7 tray sufficient, or is an 8X10 preferable for 4X5? What kind of light bulb can I buy to develop by visual inspection, and are such bulbs available for normal sockets?
Thank you.
