strikes the diffuser, which in turn, scatters it in all directions.
When
the light reaches the negative, it is traveling in a nondirectional pattern.
The effect of using diffused illumination is that minor negative defects are
not clearly recorded on the print.
There is a general softening of the
image sharpness and this is accompanied by a reduction in image contrast.
These characteristics make the diffusion printer very popular for use with
portrait negatives.
3. Printer and easel adjustment (composition).
It is necessary, before
making an exposure on the paper, to compose your image before making an
exposure on the paper, to compose your image on the portion of the easel

Follow the steps listed below to make the
