    I use PCB Einsteins with Carestream half-speed blue in the studio. I rate the film ISO 25 under those conditions. But bear in mind I'm using a Packard shutter — so I'm not sure how accurate the nominal 1/25th second exposure is. I suppose I could put a modern lens with a Copal shutter on my camera & do some tests. If I do I'll let you know the results.

    Good lows, mids and highs. Looks like you nailed it XTOL six minutes? So now u know

    Kallitype print made from 14x17 double-sided, green latitude. Developed in D-23 1+1 in a flat-bottomed tray. I posted the video in the On Photography section.

    What developer and for how long?
    I have found that most x-ray films will yield a reasonable negative at a speed of 100, exposed during the middle of the day.
    Perhaps your developer is too active. Have you ried diluting it 1 part developer and 2 parts water?
    Are you developing under a red safelight kept at least 4 ft away? This wil give yo the oportunity to watch it develop, andmy money is on your under-developing in the beginning.
    Hello Mr. Jim
    Please, I would like to have some help.
    This is my first time developing an X-ray film and I was hoping for some guidance.

    This is Fuji Blue X-ray film. Filmed at ISO 25 with a 4x5 camera
    I have the original Rodinal raw.
    I have a reel for development that I have 3D printed, because I use dishes as I don't have a safe light.
    according to your ink,
    Optimal Rodinal Dilution
    Suggested time, temperature, agitation.
    thank you very much .

    Exposure with electronic flash depends on the unit. They put out different amounts of blue and UV which are important to the x-ray film. I wonder if adding a blue gel would help decrease the amount of exposure needed.

    I plan on using D23 diluted quite a bit. Does anyone have any suggestions for dilution and development times? I've been clicking through the pages but haven't found this yet. Thanks!
    I don't know what you mean by "quite a bit", but most people I know use it at 1:3. Since I develop everything by inspection, i can't suggest times.

    I may be wrong but a filter being subtractive it wouldn't add any more of the required wavelengths to the emulsion and so at least do nothing and probably just increase the needed power from the strobe.

    Jim is correct as always

    I wish I had been told to to process by inspection 11 years ago

    However, I process often in gas burst tanks with 1/100 Rodinol and you will need to find your own times, temps, agitation

    Plan on running 100 sheets just testing
