Am I correct in assuming that DIAL NORM +4 indicates that the decoder should be increasing the volume by 4dB, meaning that your disc was encoded with a dialnorm value of -35.
I have encountered an anomaly using S&M ver 2 that I would like to share and get feedback.
I recently purchased a new flat panel and, in order to get the best performance, I decided to familiarize myself with doing a DIY calibration using CalMAN ver 5 software and a reasonably-priced colorimeter. BTW, the entry cost of a DIY setup like this is less than $400, which you would spend for a single ISF calibration. IMO, it is a wise investment for those who have the time and desire to achieve the best performance from their video systems.
The CalMAN software is designed around the AVS HD test pattern disk. The disk includes the standard tests for brightness, contrast, color, tint, sharpness, etc., as well as a number of windows used to adjust RGB balance and gray scale. I ran a full calibration on my new display, and was quite pleased with the results.
Several days later, I popped in the S&M disk to compare my calibration results against the excellent test patterns on this disk. Brightness and contrast comparisons showed no difference from what I was getting using AVS HD, which is what I had expected. However, the tint and color tests yielded different results, significantly different, IMO. For example, AVS HD set color to 50, and S&M set color to 54. Tint on AVS HD was set to 0, while on S&M it was -2R. On the AVS HD color test, I had difficulty distinguishing a color change (using the supplied blue filter) from 48 to 54, a range of 6 points. On the S&M color test, using the S&M supplied color filter (level 2), I was easily able to zero in at exactly 54, with both 53 and 55 showing distinct differences. In other words, the S&M color and tint tests seem to be much more accurate than the AVS HD. I'm curious as to why this would be the case? Should I report this to Spectracal?
Using the S&M values for color and tint, I re-ran the display calibration, re-setting the RGB balance based on the new values for color and hue. Also odd was the fact that the new calibration yielded significantly better results for gamma and RGB balance, as shown in the screen shots below:
Original calibration, with AVS HD settings:
New calibration, with S&M settings:
Is there an interrelationship between color/hue settings and gamma? Otherwise, I'm having difficulty explaining why the newer calibration looks so much better. Not complaining, though!
