INDEPENDENT dr5 TESTS
Here
are some comparisons of films and processing options. With the loss
of Tech Pan film, and the problem of film grain becoming more apparent
when scanned, (opposed to enlargement) many digital photographers are
looking for better ways to process their black and white films. dr-5 Chrome processing shows a distinct advantage over film processed as
a negative. Velvia, when scanned and converted to grayscale shows more
grain than this illustration describes, when large amounts of contrast
are applied. My
tests are ongoing, as I now am testing Efke 25 film. I will keep you
posted.
