Loris,

If I over print a Burnt Sienna layer on the Alizarin Crimson layer, and
bleach back, will the crimson layer also get bleached back, or first the
Sienna layer than the Crimson layer, or..

Best,

Cor

Hi Cor, thanks for the interesting observation.

BTW, you may use a slightly stronger bath (up to 4-5%) and/or do longer
soakings in the bleach and/or try spray / brush development after the
layer
is - comparatively - softened "in order to shorten the development
times".
Spray / brush developed layers are sometimes very interesting... (Due;
graininess or slight brush marks or selective development.) Overexposure
+
bleach bath makes you work with the brush much easier (especially you
have
manual dexterity problems); because the layer isn't as vulnerable to
abrasion as it is with normal exposure + water bath method...

Regards,
Loris.

...I took the same negative as above (high density, in general you do
not
want that for gum) I made a gum layer with quite some Alizarin Crimson
(eye
balling here) and exposed for 1 hour, really cooking the gum layer. Then
I
started slowly bleaching back in 2% chlorox, 15 min in the bleach (2%)
15
min in the water, for about 2 hours...
