DEAR TITRISOL,
Below you used the word "was" describing LPD. As Mark Twain
once said, "Rumors of my demise are greatly exaggerated". It seems alive
and well: http://www.bhphotovideo.com/c/search?Ntt=ETHOL+LPD

Ethol LPD was a great warm tone developer when used diluted
1+3 or 1+4 up to 1+15
You do not see much difference in the tone (except it looks neutral) but
when selenium or sulfide toners are applied the difference is incredible

Long ago, when I was using Ilfobrom paper, I objected to the greenish
tone I got with Dektol. I did not get this problem with Amidol
developer, but it was expensive to mix up. Examining the differences,
and trying various things, I concluded that the secret ingredient in the
Amidol developer was not the Amidol, but the fact that the formula I was
using used benzotriazole instead of bromide as the restrainer. Since I
knew that Dektol was a lot like D-72, I mixed up D-72 using
benzotriazole instead of bromide, to my complete satisfaction. The paper
happens to need less exposure with the modified D-72 than the Amidol
developer (Ansco 113?), but the speed increase is not really important
to me.
