[pure-silver] Re: Development modifications for higher sharpness

Perhaps "energetic" would be better than high energy.  But still
somewhat vague.

I have seen the following statements concerning the addition of iodide
to the Beutler formula.

1. Addition of iodide can emphasize flare and lens aberations.
2. Not needed for modern emulsions.
3. Never did anything anyway.  The amount has been described as being
homeopathic.  (I particularly liked that comment about homeopathy, ie,
quack medicine.)

Actually, "high energy" is a very vague term used in darkroom literature
for which there is no real chemical correlate or substrate.

Why?
