You seem to be a great misunderstanding here. It is not my position that needs to be backed up, it is yours. Your position is absolutely ludicrous, as A) It has no evidence. B) It has no reasoning. C) It is completely logically flawed and D) It is completely against accepted settled established...

You're now using ad hominem to defend an untennable position, and that's an extremely bad argument on top ignoring the actual science. Established science has determined the sensitivity of the human eye quite well, any claim to the contrary is bunk. The more extraordinary the claim, the more...

You mean thin DoF? That looks like DoF from a 50mm lens close up still. Even at f/2.8 it is that thin when you focus that close.

And Grant is wrong. Blindly believing something out of a book contrary to evidence sounds like a bad idea to me, and is fundamentalism. Practical experiment shows it is wrong. Basic science and logic shows that it is wrong. If you put an optical density filter in front of the sun of 2.4d vs...

This is incorrect. Higher dMax are useful and great in slides as long as there is detail separation. End of story. There is no argument against this, and is easily confirmed by adding density to a slide by various methods that keeps separation and you can see this on a light table easily. The...

No, highly doubtful. You need to make a comparison to see it. Those claims are also based on that the eye can’t see more than a certain dMax, which is effectively a certain light level and that light level is well above what the human eye can actually see - and also relatively to the backlight...

I looked a at them directly oh a light box, the difference is very substantial and a lot better contrast. You can’t project black so you’re limited by the brightness of the projection surface with the projector turned off etc. Thsoe tests would be carried out and tested under normal home...

My old article. Anyone here using Fomapan R100, I want to warn that you should use a developer without a typical solvent for clearing highlights in it like you would for reversing say T-Max. It should be solvent free (no thiocyanate, no thiosulphate), every test I did I would otherwise get...

CD-2 works well for b&w dev I found in the past when I used it. Its available at artcraftchem I believe.

This looks perfectly reasonable for 50mm to me. 50mm does require you to get close up for a close up like that.

Well, use Xtol. If it’s too fine, use dilute Xtol, if you don’t like how it looks add a solvent to Rodinal. Or add some Rodinal to dilute Xtol. Or use T-Max 400 @ 1600 in Rodinal

Side note: if you add 5mg/L of potassium iodide to working developer you get a significant resolution/sharpness increase on FP4+ from my testing without altering characteristics or development time

Yes it's safe to filter working solution of Xtol, if you think it's precipitation due to cold, warm up it first.

You have to warm up your chems, at least the developer (others arent as important tbh, they are done to completion, meaning you can underdo them but not overdo them) to 38c, have 44c water on standby ready to go and a plastic paterson tank, presoak with the 44c water, this will bring the...

I ran a lot of Xtol and didn’t run into that, you filtered out undissolved developer agent by the sounds of it. I filtered my replenished Xtol solution when it started to get cloudy or grey and it got crystal clear after (and a dirty coffee filter). No impact on negs, but everything was fully...
