I have been noodling with the idea of using my digital camera to perform some calibrations of my PJ/screen. I realize there are obstacles to be avoided and I was hoping this group would help point them out to me. I have started to create a list of requirements.
Disable Flash
Disable White Balance
Tripod mounted
Slow exposure
Raw or nearly uncompressed data
Light conditions same as viewing
Camera as close to screen as possible
Ambient light minimized
One of my digital cameras allows me to view the histogram and statistics so I should be able to tweak in real time. The other ones allow me to upload scripts that will run so I can configure a batch of pictures and let it run.
Basically I would start with my DVE DVD and go to the Contrast and Brightness to see if they are are at optimum levels. Then I would move on to the color and tint. I would also take a gray ramp and see if any color is bleeding into the image.
Do you guys have any tips I should consider before I start my experiment? I should know if this is going to work after the first test or two. One thing I realize is that when the image on the screen changes the reflected light will also change the light environment. Maybe after a few tests I will have a better idean idea on how to minimize the effects on the calibration.
This is just a low tech on-the-cheap calibration. I realize they make equipment that does this but I am just noodling as I said.
