<p>Hi,<br /> I haven't developed B&W film for awhile, but developing my kodachrome as a negative seems quite interesting to me.<br /> If the Rim-Jet backing is so hard to get off, I was wondering if using acetic acid as a stop-bath would be appropriate. Has anyone tried using carbonic acid or another very soft acid as a stop-bath? Do you think that this might do any good? I'm also wondering if the non-hardening fixers pH might be raised in any way. Not hardening the emulsion might prove to be a problem, but would using formaldehyde (as in E-6 processing) after the backing has been rubbed off do the trick? Hmmmm, solving this problem could prove to be very interesting.</p>
<p>I might try to get in touch with someone who ran a kodachrome processing machine to see how they dealt with this.</p>
