Uneven tray development with X-Ray film

[koraks]

Just upload it and edit the properties so that it's open for everyone to see and edit. It's pretty simple, just click through the different screens a bit.

The Xray film thread is well worth the time it takes to read.

Twenty well spent hours for me.

I should have some time tomorrow to try out the google docs for the notes on X ray film thread.

Also, I developed 3 5x7's to see if I could beat the mottled film thing. I turned off all the safelights except one far away and otherwise developed in the tray per normal periodic agitation. Also tried one with continuous agitation. Both look fine while wet. They are in rinse as I type.

Once again, it looks like my impatience got the better of me. I do like watching the image appear but even more I like even development! I know from hard experience that most Red LEDs will eventually fog green sensitive X-ray film or at least CXS Green and Ektascan B/RA but I thought I could get away with it and I wanted to see if my exposure compensation was right. In my defense these are new LED bulbs but even so.

I made a safelight out of red waterclear LEDs having emission at 660nm. I have not been able to demonstrate any fogging on paper. I don't know about xray film, but I strongly expect it would be blind at this wavelength. I think waterclear LEDs of a given wavelength are probably safer than the coloring of plastic cased LEDs.

It took me 3 weeks, in fits & starts.

Only 3 weeks? I have messed with xray film for nearly a year now and I'm o ly starting to get usable results.

I am 18 pages in so far and enjoying the discussion, and already answered at least one question. Too bad the image links are gone.

3 weeks to read the main x-ray thread. I had my development down in a couple of weeks.* Started with tray, but have moved to the (sadly, discontinued) HP Combi-Plan. Made the switch for 2 reasons:

1) As I'm doing stand development, tray processing takes too much time when processing a large batch of negatives.

2) I haven't been able to get good results on Kodak HSB (double-sided emulsion) in trays, but it works nicely in the HP tank. Since I plan to switch to the HSB when I run out of Ektascan B/RA, it behooved me to change methods.

*I did not order film, chemicals, or darkroom equipment until I had read the entire x-ray thread.

The missing picture links are a disappointment but Sergei has lots of his beautiful images in that thread and some very interesting things to say about how they were exposed and developed.

Thanks Sergei

Carestream G/RA and Rodinal are available in Dublin thankfully.

Thank you for the kind words, Sean

I am drafting some bits on way how i work with Xray film on me site. As well as some other things - trying to get in habit of blogging again.
