Thanks everyone ... I'll try it tomorrow morning and then upload the result both here and into the main galleries. @zhounder ... thanks. On this PC (Win95), the monitor dates to 1998 and does not reach a perfect callibration. One of the monitors on the SETI farm is better but also does not get a perfect callibration. Someday I may have to buy a new monitor ... sob, sob. If you don't understand the "SETI farm" reference, search for the 2 threads, "My little Corner" in this forum.
