Yes, just explaining how & why that works, BTW i used to have my own
darkroom as a 12 year old, (66 now), light affects film because it is/was
formed from silver nitrate, where the light hit, turned black/grey when
processed, unexposed portions were removed in the developer. We then end up
with the negative. We use this to reverse the process on silver nitrate
coted paper, (2 x negative = positive) so, if the colloid is clear, it
seems to indicate no light/impurity interaction (maybe the water used was
purer than normal) ??

BTW, the beam of light in 3-D is due to the Tyndall Effect.

Hi normally i don't post but personally i would say these are good signs,
the yellow colour i would say is due to slightly larger particles and
slight oxidation causing reflections from light. The fact that there is no
black residue would to me indicate a cleaner, less oxidised process, the
fact we see the laser beam is because of refraction & reflection of the
beam off of the silver, the wideer or more visible the beam, the higher the
particle density and probably smaller particle size (which would also
effect the wavelength, and there by colour you see, or don't see refracted
in the colloid. If i am wrong please someone put me right. Open to ideas.

Hi, Lately I've noticed that when I clean my rods with a paper towel
nothing comes off of them. Also no black speckles in the eis and no light
yellow color. Laser shows a wider line and can almost see speckles in the
line... not the nice tight line I used to get from my silver puppy.
Any ideas how to get things back to normal?
Thanks.
