This is for RA-4 printing. I have Ilford filters and I just use my normal filter tray with those, but I wanted to try something more convenient for this process, since I don't have the luxury of a dichroic enlarged.

Update: here is my new filter organizer setup. Should work perfectly.

The top image is Frankenstein 200, and about when typica density looks like, despite my ipads exposure making it look thin. The bottom two are IR film. Notice the blow out on the edges of the frame, too.

1st image is also mine. It's also too dense, but was at least a 'usable' image. Printing with it would be an absolute pain, though. I load and unload in my darkroom, which is light tight. Fpp Frankeinstein with the same subjects were loaded, shot, unloaded, and developed in the same sessions...

That's what I thought, and have experienced. I wrote my replay before seeing this. I do have some darker filters and a few boxed rolls of HIE in 35mm in the freezer I picked up. Waiting for spring to try them, though they are 30 years old and come from unknown storage. I also have some...

I don't think I've had sharpness issues on the result. I'm stopped down to f/22 +/-2/3, and I understand at that point, the focus shift should be negligible. None of the lenses I use are of a single element design, for that matter. 2 are tessar types, and one is a triplet. I think my next...

yes, I know it will be a fairly regular pan film without a filter, but have still seen very dense (but also low detail) negatives with them. I only got the film last month and it lists its expiration as 8/23, so it should be good. There is no base fog on the edges where it was held in by the...

Immediate update: It has occurred to me that it might be that the bellows of my chamonix is not IR safe, and cursory googling says this might be the case. That would explain the fogged look. Disappointing.

I have been trying out rollei IR400 4x5 film, but have not had success with my Negatives, which all come out very dense. One issue I have is finding conflicting information about development times. I have been using D76 stock. The box gives a time of 12 min, the online datasheet gives 10:30...

Will do. Maybe I should get around to uploading the print files, as well. I have a backlog of useful things I have made, but not uploaded for this, included a replacement filter slot and negative carriers I was missing

Thanks, that's what I was figuring. Yeah, 4-6 is probably about right with these filters, in my experience with the same brand of filters on a smaller enlarger. Pretty much any filter number I've practicably used required 3 filters max (per yellow and magenta setting).

Hello all, I am grabbing a set of arista color filters for my Omega D enlarger. I am going to 3d print a a box for each color that will have pull-out slots for each of the 7 filters, but it occurred to me that I could make square frames to mount the filters (like how Ilford's below the lens...
