Hallo to you all,
The dry-down factor of a paper is programmed into the RH Designs Stop-clock professional with great success in retaining the highlight details.
The pre-flash time of a paper with the RH Designs pre-flasher has been established as the time shorter than the one that displays the slightest tone on a dry blank print.
The pre-flash is used to bring down a highlight to the required tone without extending the exposure time with the consequence of "blocking up" the shadow areas, in other words – when using the pre-flash the detail is retained in a shadow area whilst the highlight is brought down off paper white into a detail tone. This is done on test strips without the dry-down factor.
When the actual print is made the dry-down factor is programmed into the timer, but not into the pre-flasher.
Should the pre-flash be reduced by the same dry-down percentage?
How can a percentage be put into the RH Designs pre-flasher when the times are in f-stops?
What are your routines with dry-down and pre-flash times?
Your thoughts/considertions welcomed!
