Sandy. How hot is the water and how long do you wash it? That scares the crap out of me because I have accidentally done that a couple of times over the years because of an odd plumbing situation and the emulsion swelled and came off.

Back to the question. You don't need high temperature to clean a negative fluid mounted with an oil such as Johnson Baby Oil. I use temperature of about 100º F, with a mild liquid dishwashing degreaser, and a bit of hand agitation. After a couple of minutes all of the oil is gone, then I give the negative a rinse in running water of 2-3 minutes and hang to dry. I have never had a problem with emulsion swelling working this way, and so far I have worked with FP4+, TRI-X 320, TMY, BPF 200 and Tmax-100 and Tmax-400.
With the Kami fluid you just wipe off the excess solvent and hang to dry. But, as I mentined, if the scan takes a long time the Kami fluid may evaporate, so for very long scans an oil works better.

Thanks Sandy, I'm going to give that a try before purchasing a kit. Thanks for the advice.

Sandy, what type of tape do you use to tape down the film?
The reason I ask is concern over sticky glue residue on the film after the tape is removed.
OK, I fear some folks are going to jump all over me for this, but here goes.Quote:

It works fine, is very inexpensive readily available, and does not leave residue.

Thanks Sandy, a simple economical solution.

As I mentioned in another post, I tested with glass of both thickness and found no difference in results between the 1mm and 2mm thick glass. That being the case, the use of the 2mm thick glass is much more advantageous since it much sturdier. I broke several pieces of 1mm thick glass just by picking it up in the wrong place.

I'll do test scans 1mm above and below the negative carrier height to see if it makes any difference with my 4990, probably not.
If not the window glass should be cheap. Thanks again Sandy.
Hello! How much does the quality of the glass affect the scans? Best regards.

Plain soda lime float glass works fine for me. There are speciality glass that have better transmission, especially in the UV wavelengths, but I don't believe they would provide much improvement in this application.Quote:
