Water Spots on Negative

[tim_kimbler]

I have had good luck developing TMAX 100 with my Jobo tank and an old rotary drive base. My question is how do you remove water spots left after development? I hang the negatives from a string and let them air dry, yet water spots are often left on the negatives.

I presume you're using Photo-Flo 200 @ 1:200 as a final rinse. If so,

and you're still getting spots, try mixing your Photo-Flo in

distilled or filtered water. If all else fails, mix all your

solutions in distilled water and install a filtering system on your

water line for washing. As for removing the spots you already have,

rewash and treat in Photo-Flo. That should do it.

Are you mixing your chemistry with tap water ? In certain parts of

the country, public water can be downright nasty. I would suggest

making a run with chemistry mixed using distilled water. The spots

could be residue from undesirables in the tap water. I use a JOBO

CPP2 and use distilled water and have not had a problem.

Distilled water is the way to go with the addition of photoflow 1:400.

But don't mix all your chemistry with distilled water because you are

mostly interested in keeping spots from developing when the film

dries. Just use distilled for the final washing. Most of your washing

can be done with regular tap water and just the last couple of minutes

with distilled and photoflow. Of course you can also use a mild dish

soap as a surfactant. Just make sure you dilute it very well. A drop

per two or three gallons. I've never had any spots and I have really

cr--py water. Try it.

I would recommend that you use distilled water not only for your final

rinse, but also for your developer. Stop, fix, rinse, hypo-clear, and

wash can be done in tap water. The reason that I use distilled water

for development is this: Tap water varies widely. If you use

distilled water for development, you will know that no matter where

you move to in the future, your results will be the same. I'm

certainly glad that I have been using distilled water for my developer

for many years because I had very hard water until I finally installed

a water softener. Just out of curiousity, I did a test. I developed

film in my unhardened water and then again with my water after being

softened. The results showed that there was a significant difference

in my negative densities affecting contrast. Eve my E.I. was

different. If you use distilled water for development, you can always

be confident that no matter where you are, your results will be the

same. Consistency is most important in darkroom processes.

As for water spots.....As everyone else has already pointed out, use

distilled water and PhotoFlow. It's as simples as that.
