Hi Gary, Although your instincts may tell you to tinker, in this case it would be advisable not to alter the formulation. The products are highly refined and the research which has gone into them is second to none. Papers all respond differently and we have not tested every paper with Tektol, but we...

I wouldn't advise using deionized water for your wash as you are more likely to compromise the overall washing sequence without the benefit of running water. Developers that recommend the use of distilled/deionized water in the mixing process do so to avoid any reaction with compounds often found in...

Hi Keith, Hopefully someone with expert knowledge will contribute an answer, but as far as I am aware you can use distilled and deionized water interchangeably for general photographic purposes. I believe that deionization is a less expensive process, but trace particles could still be present. Thes...

If you buy some art card or mounting board, depending on what will fit best into your neg carrier, you can cut it to size and sandwich the neg into your 5x4 holder. Alternatively, you could use a 6x6 holder and file out the opening so that the borders would be shown in the print.

That's strange. F76plus in phenidone-based and has a long shelf life. I am personally using a half empty bottle that is two years old. It is clear and works perfectly, so I can vouch for its longevity 100%. If the developer has darkened then this usually indicates exhaustion, but I'm sure Lowell Huf...
