PEAK™ Enlarger Focuser
Tips for use: Focusing Difference
It is important to not enlarge an image that exceeds the specifications for
the lens being used in the enlarger, other wise aberrations of the lens will
occur and there will probably be a difference in the degree of focus between
the center spot of interest and the peripheral points in the image. Even if
an enlarger with an automatic focussing feature is being used, it is still
recommended that the degree of focus is validated from time to time.
