Didnt get to do the other calibrations for primary or the other stuff lower in the page. Gamma was off and not too sure how to get more brightness out of tv as result was a little too dark for my preferential taste.
I am using the Rec 709 Disc and the Disney WOW for contrast and brightness as I don't have the DVE disc.
Where I was confused before is I thought the HCFR provided the greyscale IRE steps and wasn't sure to use the ones built into tv which has from 5 to 100. Obviously, used the one one on tv.
I calibrated sensor with inside of black plastic garbage pale (cleaned of course). My tv is Plasma LG 60 PZ950.
I am going to give another go and will focus on gamma, brightness and contrast a little more next time.
Here was my problem...I had upgraded the HCFR software and couldn't get all to balance once hit 15 IRE and beyond. Once I downgraded back to v2.0.1....BINGO!! I will try to post before and after 2nd time.
Like I said before, I am a TOTAL NOOB but I like the challenge and learning as I go along.
Please forgive my silly questions...
1. Do you guys recommend using the set up as described on site by measuring ftl? Or is my calibration disc ample to do contrast and brightness?
2. I usually like cooler temperature in colors. Will it totally defeat purpose if I switch to medium after greyscale calibration?
3. Does meter measure MLL after calibration? Where/How if so?
I have many more questions but don't want to bombard you with my ignorance.
Again...thanks all for sharing!
1. Contrast and Brightness should be done by eye using the pluge patterns for light and dark. Brightness impacts your black level and Contrast impacts your brightest white point. These need to be set by eye, because a meter has no idea whether your crushing blacks or whites. The only time a measurement comes in handy for this is if you get to a 100 contrast setting, and you're still not crushing whites. With a large plasma, you've likely got some power saving system built-in, so contrast in particular may have a big impact on both gamma and white balance, and you likely will be nowhere near a 100 contrast setting. I just recently calibrated a 65" Panasonic VT30, and I believe 72 was as high as I could go on contrast before it would start impacting gamma and white balance.
2. You don't want to make changes after calibrating, as it would defeat the purpose. Instead, calibrate to a different white point. If you think 6500K is too warm, try moving up in increments. This will still give you a uniform grayscale, which will look better overall.
3.I would recommend waiting until after grayscale and gamma calibration to even bother with measuring absolute black (if at all). Personally, absolute black readings from a meter that may or may not be accurate down that low mean very little to me. I would rather ensure uncompromised shadow detail over maximizing an absolute black measurement.
Feel free to ask away as far as other questions. This forum is a great resource for the DIY types, and believe me, we've all been there at some point!
