I've looked for a thread showing black and white slides, but found none, so I'm gonna start this one.
After some weeks testing developers and bleaching combinations, I'm finally happy with the combo D-168 and D-158 developers over Fomapan 100 processed as a slide (reverse processed, I guess is the correct denomination).
Here are a couple of them, exposed with an Angulon 6.8/90mm f/22:
Thanks, Bryan.
I mainly followed Ian Grant's intructions on APUG but customized the bleach bath to: 10ml Sulfuric Acid + 2.4grs Potassium Dichromate + 990ml demineralized water in 3.5 minutes.
Don't forget to use hardener in the fixer if you use Foma films because they are very easily scratchable.
Interesting. What are the advantages (apart from the ability to project) of reversal processing?
I look forward to seeing more of these images.
I've used the reversal B&W images mounted in a light box rather than projected. When developed to a full tonal range (8 to 10eV and may be more) they make for a spectacular presentation.

My experience with (35 mm) reversal processing indicates about a 1 to 1 1/3 stop increase in film speed, coupled with a great reduction in the visibility of grain -- effectively, the coarse grains develop in the first developer and are bleached away, leaving the finer, less sensitive grains for the reversed image. So, Tri-X at EI 1000 with the grain of Plus-X. Perhaps less important in large format, but any real speed boost is welcome when shooting hand held with a Speed Graphic...
If a contact print at arm's length is too small to see, you need a bigger camera. :D

"This formula will produce less than satisfactory positives.
I wish I could enlighten.
There will be published reversal tips in the upcoming new edition of the Darkroom Cookbook / Anchel"
That was in 2008, does anyone have a copy of the edition? Does it actually have reversal tips?
Some re-digitized slides, trying (with tiny success) to correct the mistake while bleaching, as you can clearly see in second and third images.
Both are Fomapan 100.

Do you mind giving us a bit more info about these developers?
