Welcome to LFPF

5x7" FUJI Super HR-U, parodinal 1:100, Mentor Studio

I have a problem. Caffenol + FUJI Super HR-U
White points in negative.

Try Rodinol 1/100, works great, don't overdevelop

Caffenol is for experts, so I never use it

[Fr. Mark]

I agree with Tin Can about Caffenol. If it works for you, great. However, the more reliable Caffenol recipes in my extremely limited experience have Vitamin C in them. I'm pretty sure that Vit. C is the developer or kissing cousin of the developer in Xtol. So, I suspect that the Vit. C is the developer not the coffee. Dilute Rodinal and Dilute Pyrocat HD and many other "real" developers work well for Xray film. A form of Rodinal can be made from Tylenol, too, if you want to do some seriously "alt" developing. Tylenol (Acetaminophen) is acetylated para-aminophenol (The developer in Rodinal) and the process of making it basic enough etc to perform as a developer de-acetylates it. Alternatively, just buy p-aminophenol from your favorite chemical supply store and make your own in the more normal way. Do wear safety glasses/goggles, the sodium hydroxide in it is really bad for your eyes.

Mind … blown!

I've really been liking my results in D-23 1+3 (1+2 for carbon printing). I've tried caffenol, but B+F was too high for carbon printing.

Rodinal does a little blackening for me. Cafenol - ok black. I try simple developers - I fold d23. (Sorry - I don't know English. I write / read with a translator. The photographic experience helps

I've seen the same in pyrocat-hd. Use extremely dilute developer with HR-U.

Has anyone tried the Adox Supersafe Darkroom Light with X-Ray film?
