It could be. The amount of metol in standard D-76 is
minimal. I would suggest increasing it to perhaps 5 grams
per liter.
Also, in general, the activity of the developer is
slightly lower than standard D-76. This is shown in the
graphs in the 1929 paper from Kodak Research Labs. Metol and

Well, as I said, it *might* make sense to buy chemicals in bulk if
several people set up some kind of buying club to pool their needs, but
it would require a lot of coordination to make it happen.

Is it possible that my home brewed, 'improved,' no hydroquinone D-76
would be less active at 1:3 dilution than standard, out of the box
D-76? Although my home made D-76 compares favorably with store bought
D-76, results at 1:3 seem underdeveloped.

I live in India.
Even if the chemicals would be cheaper, what about shipping charges?
I wanted to buy Phenidone and CD-4, which are _not_ available anywhere
in retail in India, and had to buy 1 KG of each.
And minimum shipment size for Ammonium thiosulfate was 25 KG.
I heard there are some who claim to produce Amidol, and thankfully I

Good question. Presumably someone (the importer) would need to have the
proper licenses and such. Lotsa paperwork, but it's probably possible.

Developer will have some effect on original image color
and toning. In general warm tone paper has somewhat finer
silver grains than neutral or cold tone paper. It is the
size of the grains that largely determines the color of
silver images. Fine silver grains generally tone more
rapidly than coarse grains partly because of the ratio of
