Black blobs along Velvia 50

IzzyCat · May 23, 2018

Hi there

They may not be the shots of the century but those pictures have a lot of meaning to me.

Picture is self explanatory.
It looks like it is emulsion side, each blob do materialize as a small bump in the emulsion. I hope it’s some stab residue... Film is Velvia 50 home processed in Tetenal Colortec E-6 chemistry.

Thank you everybody

Forgot to add my main question : Can this be washed off, and how ?

Dearest thanks to you all <3

You can always rewash film at will, but note that you always have to repeat the final rinse step at the end. You did mix final rinse from deionized water, yes?

About these patterns on the left hand side: this looks to me like underdevelopment or retained silver. Either something blocked developer or BLIX from reaching the film, or the fill level in your film tank was insufficient. If you are lucky, then this was insufficient BLIX, in which case you can redo BLIX/wash/finalrinse steps and (hopefully) recover your slides.

Those look like foam or airbell marks from rest cycles during small tank agitation. How much solution did you use, and what type of agitation? Are you giving the tank some kind of impact after agitation cycles?

And if that is the case, it's irreparable on the film itself.

bvy, it could - at least theoretically - be retained silver, e.g. if FD/CD steps went fine and then BLIX volume was too small. In this case one could recover the slides. Agreed, though, the odds of exactly that happening are not all that great.

I don't disagree. The marks themselves indicate that *some* solution is forming bubbles at the surface. If it's not one of the developers, then yes perhaps they can be recovered with a re-blix. Certainly doesn't hurt to try.

Thanks y'all !
That strip wiil get back into the soup.

But... As it's been cut already, how can I hang it to dry ?

Safety pin through the sprocket holes?

I keep your idea for 35mm... But the strip is 120 film ^^ Thanks !

You could use a clothes peg to clamp the outer edge of your film strip against something. Alternatively, you could dry your film still in the spindle.

I use clothes pins on the unexposed portion of 135, 120 and 4"x5".

There are film clamps with steel pins that need less area and do less damage than other clamps:
