Eco Pro Tektol Reviews

Economical warmtone favorite

I've been using his developer solely since first testing it against Dektol and Multigrade. I did not notice any significant differences in tonal reproduction, but this one was more economical. Also, it seems to selenium tone my Ilford Warmtone paper better, toning a bit more fully into the upper values before going too red in the lower ones.

Works great

Unopened, the Eco Pro Black and White Paper Developer has a shelf life of approximately 2 years when stored in cool, dark conditions. Once opened, the concentrate should ideally be used within 6 months to maintain optimal performance.

I live in warm climate the Caribbean to exact so my water temp are generally 25-29 degrees all the time. Can I use this developer to develop at such temperatures?
Asked by: Raik
It is important when using this developer to get the temperature down to 20 C, or 68 F. When the temperature is higher it is necessary to greatly shorten the developing time, otherwise the paper can be over developed, and gray out the whites. A little ice can help to lower the temperature.

Does this have to be specially disposed or can it be poured down a regular drain?
Asked by: Adam
From my research, Eco-Pro developer can be poured down the drain. I bring all my used fixer to the dump where it can be disposed of correctly. This developer is fine to go down the drain from my opinion.

question

About how many prints could you make with this before it's exhausted? 5x7 or 8x10 size.
Asked by: Arra B.
Do not not made more than 5 or 6 prints since I have notused a wet dark room that much except for developing negatives which I have been scanning. Planning on doing more in the coming months. Sorry I couldn't have been more help.
