This stuff is pretty easy to work with, but I'm still learning how to use it. It's a lot more sensitive than Gum bichromate. Eventually, I'll try making a tri-colour print with it...

 
Interestíng video once again. I also preferred the sized print for the same reasons you gave, Andy

Interesting! I wonder if your test there that the dilution for the cyan was too much (even though Calvin's advice) as there wasn't much left after the wash & as I am not familiar maybe the exposure was too short?? Just my query...

I tested the exposures on separate paper before doing the kallitype overs, and yes, the overs were thinner, even with 1+1 dilution. The second passing improved it. Of course, more testing will have to be done. I didn't try straight out of the bottle, which I will do. Thanks! What startled me the most about this stuff, is the speed. Calvin wasn't kidding when he said it's up to 10x faster than gum bichromate. In my case it was much faster than that!
 
Could it be that you are getting better contrast in the case of the sized print simply because of the sizing itself. There seems to be hardly any blue in the print (except outside the image) so perhaps most of it is getting washed out. On the other hand the unsized print looks toned as would be expected. I am not sure I understand why that was not acceptable. I think Calvin recommends using a clear PMF as a size if I remember correctly.

Thanks for the video, by the way.

:Niranjan.
 

It's weird that the blue washed out more from the print rather than the edges, as the entire paper was sized after I made the kallitype. I'll have to try the clear PMF. Thanks!!

I would suspect that the reason for the edges not washing out is that they're fully exposed (not covered by a negative) and the printed area covered at least with the density of the negative (in the darkest shadows) or much more.

I'm with Niranjan and Ced in wondering whether there's any blue left in the image area for the sized print. It's not really visible in the video to me. Could you show a side-by-side of an untoned kallitype and a sized-and-toned version? Also, what was your exposure time for the PMF exposure?
 

The blue is there, it's just hard to see. Exposure was 19 seconds. Too busy at the moment working on other projects but when I get back to PMF, I'm planning to do that.
