I've tried to calibrate my projector (Sanyo PLV-70) today, but this
was a complete disappointment! All in all I can not recommend projector calibration with Colorvision
products at all. It's a complete waste of your precious time (and the
expensive projector lamp time). It simply doesn't work and the results
are ridiculous!
Why is it that people try a known and proven color management product, get bad results, and assume the product doesn't work at all? If you rent a Toyota, and it breaks down while you are driving it, do you assume that all Toyotas don't work? There are thousands of satisfied Spyder2PRO projection customers. If you would like to troubleshoot your issue, rather than proclaim to the world that the product doesn't work, then contact me off list, at .
First of all, the projector calibration
doesn't allow to set the white point correctly.
When in a dark room, whitepoint is totally adaptive. I can show a gray ramp in Photoshop on the peach colored walls in my livingroom, and it runs from white to black. Not peach to black, but white to black. So if you are working in a properly darkened space, whitepoint adjustment is a waste of time, as well as a waste of brightness, since it dims the projector output to use it. But I'll go over all of that when you contact me privately.
