Fuji Super HR-T X-Ray film (green sensitive)?

I am just about to put this film into use.

I have Xtol developer (also Dektol) and Ilford Rapid fixer.

Any observations regarding development times? Film sensitivity (from what I've been reading, it's around ISO 80)?


Thanks in advance!

By the way, I am planning to do tray processing.

An EI of 80 is a good place to start. What do you plan on doing with your negatives? Silver gelatin contact prints? Alternative printing? Scanning?

Silver gelatin contact prints. Maybe enlargements in the future (on silver gelatin paper)? Would that change things?

Thanks!!

Most x-ray films have emulsion coated on both sides. I'm not sure if yours does. If it does, I don't think it would print very sharp if you decide to enlarge it. You would have to strip the emulsion from one side (the side that was against your film holder) with ammonia. It's very easy to do. If you do strip it, you should give move development as stripping cuts the film's DR in half.

How can we strip the second emulsion by ammonia? I would like to do this.

Thanks.

If memory is correct, I'm a X-Ray Tech. by trade. Mammography film ( if you can get it ) was only one sided. Plus it came in about a 8x10 size.

To strip the emulsion from the side of the film that was facing "away" from the lens, just duct tape to a piece of plate glass with this side of the film facing you. Duct tape all along the clear edge of the film so that no ammonia seaps under side of the film. Brush on (or sponge on) ammonia. The emulsion comes off pretty quick. Wear gloves and work in a well ventillated area. I wear a respirator and have a duct hose which sucks the smelly air away. Wash the film. That's it.
You will notice that the negative now has much less density. Exactly half the density it previously had. To compensate for this loss of density, develop the film longer.

Going by what information is available on the forum's archives, you can also use a weak bleach solution to remove the emulsion.

Ari is correct about bleach... use bleach, not ammonia. I use ammonia in my darkroom for other applications. Sorry for the confusion. Mind you, I use it straight, not diluted.
