Photo Processes

[Erika Wolf]

The way that a photograph looks is often highly dependent on the
photographic process that produced it. The bulk of post-war consumer color
photographs (i.e, your home snap shots) tend to age quite poorly, often
washing out into reddish colors. Early color films similarly faded out.

In contrast, such early color processes as autochrome and carbro prints (a
three negative process printed with oil-based pigments) can remain quite
vivid. Also, the particular Red-Yellow-Blue combination employed for
printing can very much influence what the over all chromatic effect of a
given image will be.

Andreev's early color images are autochromes -- an early color positive
(i.e., slide) process. They look like they might be pixillated, because
the autochrome is made of small particle filters of different colors. You
can read about this process here:
