Use of X-ray film: technical discussion with example images

Hi,

One thing I forgot to mention with the Dektol as developer. I shoot most all of my x-ray film at anywhere from ASA-25 to ASA-6. Old Kodak X-OMAT for instance I shoot at ASA-6 and T-mat L/RA at ASA-16 indoors and ASA-25 outside.
Ive used HRU before but its been quite a while, I seem to remember the Fuji X-ray films being more contrasty....your mileage may vary :-)

Also with Dektol, the development is so fast that its critical to go from Developer to what ever your using for a stop bath, QUICKLY. :-) Don't wait for the developer to drain off a corner if your using film hangers as you will get uneven development along the edges. I use plain water for a stop bath...
Hope this helps!!

Cheers

Hello again, everybody.

I did not quite like the results i got with the Agfa UV-G x-ray film, so i sliced down 2 more 14x17 sheets into 12 5x7.

In some of them, i did 2 or 3 exposures on the same photo by moving the dark slide a bit more each time.

I will write down how much time i did on each exposure, for example 2+2+4 seconds , meaning that the last exposure got all 8 seconds.

Something happened during development with 3 and 4. I cutted them a tiny bit too long and they bended in the hangers.

IMPORTANT CHANGE: i did the development with Rodinal 1+100, this time at 35 celcius ( 95 Fahrenheit) as recommended in the Agfa page.

Here are the results:

1- 1+1+2 seconds. measured at iso 25-Lens RF-240 f/5.6

I hope this helps. As always, comments, opinions and recommendations are very welcome.

Thanks, and a great day for everybody!

Hello to all,

I'm starting shooting on Agfa CP-GU. I need an advice on a starting developing combo. I shoot few sheets at iso 25.
My idea is to use HC110 in 1+63. Temperature will be around 25°C (hot summer, no way to lower the water temperature).
What could it be a good time? 6 minutes?

Thank you

Yes, try 6 minutes

Some have tried to to find the least amount of one shot Rodinol, I use 10ml per 80 sq inches at 1/100 7 minutes 68F

Too short a time will yield this

I have said this before, all Medical X-Ray is more similar that not

It has to be, or Medical users would go nuts

Industrial X-Ray is way more expensive and SPECIAL

Ektascan br/a single sided, dev. in D23 1:3 for 12 mins. Gentle agitation for the first 30 sec then 10 sec. every min. I use the SP-8X10 tray with the hold down tabs removed. Attachment 229513

It tried developing 11x14 double sided Fuji HR-U green in my Jobo print drum today and was pleasantly surprised that I didn't get marks or scratches from the ribs on the interior of the drum. This was great because I don't have room for three trays and was doing single tray processing with less than adequate results. I'm so grateful the freshly manufactured film (my latest box purchased last week has a 12/2024 expiry date) is still available. I bought it from ZZ Medical.

Wonderful!
