Not quite. This setup eliminates the variability problem of using a flashlight. Once again...the flashing source remains in a fixed position, preferrably close to the enlarging lens of the enlarger so as to avoid problems with parallax. You lay the selective flash down on your paper in the same manner that you would a burn - with a card with a hole in it. The red filter over the enlarger lens allows you to see where you're laying the selective flash down without exposing the image on your paper. Once set up this method is simple, effective and accurate.
