With ascorbic acid present, I don't know, but it would be easy to test.
If you could add exactly enough ammonium hydroxide to exactly react with
with the ascorbic acid, with the water at pH of 7, I would expect it
might break up the particles, producing a combination of both small
particles and ionic silver, identical to what you get if you had never
added the ascorbic acid in the first place.

I know I should do this myself...don't have any ascorbic acid right now.
What happens if you put a touch of H2O2 in the stable light yellow brew?

Very light yellow. It is more turpid than with color, leading me to
believe that the particles are very small so they are absorbing
primarily in the uv region and only lightly in the blue, but still
sufficient in quantity to cause a good bit of reflection of light
and thus the tremendous Tyndall. After two days it is still stable.

What color is the converted brew without the laser light affecting the
photo?

Subject: Re: CS>Making 100% colloidal EIS
Here is a link with a picture I just made. It's not very good, I
had to have the room pretty dark with no flash to even see a hint
of the Tyndall in the EIS glass. From left to right, 15 ppm EIS
with a pinch of ascorbic acid added, pure15 ppm EIS, distilled
water with a pinch of ascorbic acid added.
Note that the colors are not true. The laser beam is actually red,
but appears yellow because it is so overexposed. Then the
reflection of the beam off other particles gives the entire left
hand glass a red color, which is really only red because the laser
light is red. The actual color is more of a yellow if white light
comes in from the side, but somewhat murky due to the large number
of particles. Viewing on a white background and illuminated from
the rear it is more bluish.
