Agree. I didn't mean to imply it necessarily needs to be used "one shot". Thanks.
So, in conclusion - follow the same routine that you use when developing! Thanks
Ilford rapid fixer has for quite a while had a confusing label that refers to "Ilford Paper fixer" inside. Ignore that label.
There is a page on http://www.ilfordphoto.com/products/...ndry+Chemicals which should allow you to download the data sheet for the Product, (the page gives a popup link which I could not access)
(try http://www.darkroom.ru/info/manuals/...manual_eng.pdf ) Sugused for film is 1+4 mix (One part Concentrate to 4 parts water) with a time of 2-5 minutes, any film with Delta or Tmax in it's name should be fixed AT LEAST 5 minutes in fresh fixer.
All the "T-Grain" or Delta Grain films require more time than given.
I think you confused fix times for film and print. Ilford recommends 30 seconds for prints, 2-5 minutes for film. I use 3 minutes but do a clip test about every second film. My clip test typically gives a clearing time of around 40 seconds with fresh fixer, and minimum fix time should be twice the clearing time.
Could the dots also be related to air bells during development? Do you tap the tank, relatively hard against a surface, at the beginning, after pouring developer in, and after agitations?
Edit: sorry, just looked at the photo again, realised OP attached a positive, not a negative. Developer air bells would be white on a negative. Must read posts more carefully...
No...Rafal ...I didn't tap the tank...I now know I it's good practice even if it's not the cause of the spots that turned up on this set of negatives. Yes, Andrew...I think that's what happened....the label is awful...but now that I've read their spec sheet (which is much more detailed) I know it's six minutes. Actually I should have been suspicious given that my color kit is 6min or so but I thought I had remembered a short time last time...obviously I was wrong.
