    Re: Getting rid of tiny white spots

    I have only seen this occasionally with xray film (very soft/thin topcoat) and developers with high pH (e.g. pyro). It doesn't happen with e.g. XTOL/MyTol. According to PhotoEngineer (Photrio), the...

    With C41 the developer is the first to go off and with E6 the color developer. Check the color of the concentrates against known good concentrates. Should be colorless or the color of weak tea; any...

  5. Re: Unexplicable exposure problem with paper negatives

    Yes, paper tends to curl with the emulsion inward. However, an exception is RA4 paper when it's cut recently from a roll, as the rolls are generally with the emulsion facing outward.

  7. Re: Unexplicable exposure problem with paper negatives

    Poll: Re: Poll: Stop Bath

    Either acetic acid (film), citric acid or even a mix of citric and tartaric acid (paper). Sulphuric acid for ECN2 film. I've used plain water on occasion for film as well. Guess what...it all works.

    Re: quantities of powder to make PyrocatHD

    I've had B go "bad" on me once. The carbonate had neatly crystallized out into one big crystal. Pretty neat. No amount of argon would have prevented this.

    You can't go wrong with tmax 100 in this application, in my opinion. But delta 100 would be quite close and certainly a good alternative.

    Re: quantities of powder to make PyrocatHD

    No, and there's not supposed to be. The only difference is the storage lifetime of the A stock. It should last for years in glycol (but I usually finish a batch within a few months and then mix new).

  15. Re: Develop for sharpness and fine grain with FP4+

    Agreed.

    Also, FP4+ is significantly larger in grain than TMX or Delta100, but in sheet film, it'll be hard to see the grain anyway unless you enlarge to a rather phenomenal size. So who cares,...
  16. Re: Question on using Inert gas to protect unused Developer

    The necessity of all this depends on the developer. IIRC Steven you are using pyrocat. If this is in glycol, then no purge gas is needed in the first place.

    Peter is right. There is no magic emulsion on xray film. It's just a very basic blue-sensitive or orthochromatic emulsion with a very flimsy topcoat. Mammography film has only one emulsion side and a...

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

    Agitation is critical when using xray film. Too much and you get uneven development, too little and it's the same story.
