I agree with Rane. Suggest you flock every possible internal surface. A while back, I suddenly developed a hot spot in the center of images shot with my tube lens assembly. After considerable looking, I discovered that one ring of flocking material, near the camera end of the assembly, had shifted ...

It might be easier to judge from a better known subject. Something like the laser printing you get on bank statements is quite good. The ink spatters. Sometimes mass shipping labels have a 2D barcode in fine dots to start with, which is also laser printed. I've glued one to a slide. If you mount th...

This looks good to me. I'm not seeing any signs of motion blur or unpleasant optical aberrations. I'm not sure: the hair highlights seem to show a cross shaped pattern; if it is not present at the subject as I suspect it would be indicative of an optical aberration combined with the stacking proces...

Re: Kosher salt

The strange thing about salt is that it is not all the same, depending on the source. I have photographed dissolved and dried Kosher salt and it appears to set up differeently than ordinary table salt, possibly because it may be non-iodized. Gourmet cooking magazines occassionaly run features on ex...

Thanks.

I can make an informed judgement at 1:1 or less. 4-10x, not so much.

Rik, Not sure how qualified I am to answer your question. I do have HSS activated though if that provides any useful insight, and the Flashpoints are operating through an R2 MarkII TTL transmitter. Frankly, lighting has been the biggest struggle I have come up against; I spent quite a bit of time r...
