Localized Flashing

greenspun.com : LUSENET : B&W Photo - Printing & Finishing : One Thread

I've been using a localized flashing technique, where the areas to be affected are demarcated on my easel with tape (sort of a grid, coordinate system). I then flash the demarcated area (after determining exposure, etc.) similarly to how I would conduct a burn.

I've heard about using a penlight in conjunction with the red blocking filter (so you can see the image while working). While allowing more precise "aiming", it seems that controlling exposure might be somewhat unpredictable. Has anyone tried this? Thanks!

I remember a light wand system to use as a burning tool but what I do is use a piece of cardboard with a whole of appropriate size with a Kraft Negative Glassine envelope over the whole. With the negative still in the enlarger, I cover the whole from the bottom, turn the enlarger on and position the whole where I need to selectively flash and do the flash for a starting time of 10% or the initial time. The nice part of leaving the negative in the enlarger is that when the enlarger is turned on you can see the image on the cardboard so you can align and flash where you need. It has worked for me for years...
