Harman Direct Positive Paper Test

Two test shots on Harman Direct Positve Paper. These two shots are identical except that the left hand shot had two seconds exposure, the right hand had 4 seconds. Clearly the right hand shot is overexposed, but it also seems to have higher contrast (slightly better black)

The left hand shot has the similar exposure as the image posted previously, number 2 (right hand side), but was processed in Ilford multigrade for 30seconds, then 90 seconds in ID3 (same for both these images). Note that the unexposed areas around the edges are now black again.
