Drying marks on film

[kieran ross]

I have processed my own B&W white film but they always dry with

marks and streaks I have used wetting agent and a film squgge to no

avail. I have rewashed some which takes most of it off and cured it

mostly but still a bit marked on the shiny non emulsion side but

when i scan the negs it is pretty unforgiving showing up any marks I

have no probs wet printing them although the serious marks show.

 

If anyone has am solution for un streaky un dry marked film i would

appracitae it alot.

 

Cheers

I used to wipe the negatives with a lens cleaning tissue (only on the shiny side), this removed all of the spots.

Oh cool i will try that at some point in the fuuture is there a way to stop it in the future?

sorry i was of somewher else then i meant at the drying stage of development?

There are a number of posts about this problem that you may find helpful on this site. In the mean time, I would suggest that you put your wetting agent in distilled water, soak for 30 seconds, then hang the film at a slight angle to allow the water to move to the edge as it runs off.

Randall is right. Be careful not to use too much wetting agent - just a few drops per liter of distilled water.

After fixing and Washing soak 3 minutes in distilled water shake or agatate a few times remove them from the water dip your well washed fingers in the water and then use them as a squeegee down the film.

My last step before hanging the negs diagonally is:

 

1 liter water, 30ml rubbing alcohol, 2.5ml Photo flo for 1 minute, with mild agitation

Cheers guys use this in the future!

wetting agent tends to precipitate all the minerals in regular water, use distilled.

 

My first process were done with water from a well... even today's Digital Ice software in scanner cannot clean them.

haha thats very useful i re washed them in some distilled water as said before and they are a lot better but not perfect i will dry them diagnoly next time. But hey i have only just really got into dev and printing my own film so im still learning techniques!

I recently had drying marks on a couple of rolls of b/w film. I realised that I had got into the habit of mixing the wetting agent and water rather briskly resulting in bubbles which adhered to the film when I removed it. I didn't squeegee it -just let the wetting agent drain from the film (consequently ending up with drying marks from the bubbles)
