    Re: So what is an ISO 9001?

    One of the things about photographic manufacturing is that so few people understand it, it is hard for an inspector to tell what is going on. No company will allow an inspector from a competitor...

    Re: Any experiences using dry plates?

    I make my own emulsion (ISO 40 ortho sensitive) and coat it myself using a special type of doctor blade designed for glass.

    Plate holders

    Well, it finally happened.

    I got a plate stuck in one of my plate holders and had trouble getting it out in the dark. With perseverence, I got it out. Then, after processing the plate, I was...
  6. Re: Pissed off-venting-Fogged 8x10 film in box!

    Re: wetting agent

    Do not use dishwasher detergent. It can be alkaline, and can contain dyes and fragrances. None of this helps your film.

    Pure photo flo or an equivalent is neutral in pH and has nothing else to...
  8. Re: Kentmere, Foma, Oriental Paper Edge Fogging

    It is not normal for a paper emulsion to have a yellow stain or fog upon the removal of cadmium from the emulsion formula. Basically, you get a softer toe with a tiny change in tone of the silver...

    Re: C-41 chemicals 3-step

    Guys;

    To achieve the degree of color purity and tone scale that C-41 films currently have, they use DIR couplers and high iodide crystals. This and the thick structure makes them nearly...

    Re: C-41 at Room Temperature

    A couple of comments are due here.

    Leuco dyes are formed in C-22 and are converted to the final dye in the ferricyanide bleach bath. In C-41, the full colored dyes are formed in the development...
  11. Re: What slide format will survive the digital age

    It is likely that 35mm film will survive for quite a while, but overall sales of slide films in all formats is decreasing at an alarming rate due to digital. OTOH, negative film sales are not...

    Re: Cause of Pinholes on Negatives?

    The use of a stop bath with modern films from Kodak, Fuji and Ilford does not cause pinholes. Pinholes might be found when one is using an unhardened or poorly hardened film, but not with films from...

    Re: Stop Bath Acidity?

    Kodak Indicator Stop Bath is pH 3.0 at 68F.

    As a check, I just measured it with my handy dandy pH meter.

    I was one of the "TREKKERS" there. You should know that at EK the Trekkers were the analog photography people, so we were with you all the way. IDK what the digital people are.
