Hi, Phillipe:

Perhaps you can help in understanding a little more..

1) are you making POP or DOP emulsion?

2) What are the differences in the various photos - particularly in the second link where clearly some (top two) have more neutral color than the others

I realize an emulsion of sodium chloride and nitrate of silver and gelatin;
at 40 ° or 50° the solution is milky, whitish. I extend it to the comb on a
glass plate. I let it dry; exposes, etc.

My problem: The result is almost always mustard as in the picture below.

Any tips or suggestions would be welcome.
