Hey guys, I'm new to using CalMan 4x and the C6 Kit, have a bit of a handle on the software/workflows/etc, but I am a bit confused or missing pieces of information that is likely easy for an experienced calibrator with similar equipment or experience.
Here's the list (sorry for the quantity):
1. Selecting Gamma, general theory/question: If two gamma setting (say, settings on the display of 1 & 2) produces reasonable results around the target multiplier desired, but a setting of 1 produces a worse error on the low end and a setting of 2 produces a larger error on the high end. Which, based on experience, is the better choice/will provide the better outcome?
2. What if the tracking is better on 1 (depending upon the answer to Q#2), but the setting of 3 provides the same relative amount of error, but in the middle of the scale (say 50%white), which is preferable? 1 or 3's error location?
3. Would one need to calibrate a display completely through for each gamma point to ensure the correct one was selected for the display? Or, is this a performance issue of the display, not affected by the end result. Or is this essentially true, but beyond reasonable unless one had unlimited time to find an exact sweet spot that will change over time?
4. When adjusting White Balance, the process for two points I understand to be: measure at 30% & 80% (assuming there is only an RGBgain/bias adj). So, what's the best process after that?
Example: 30% 110 DE, 80% 90DE. Adjust the 30% until closest to 3, then re-measure both 30% & 80% and work on worse again, because the adjustments at 30% impact the 80% measurements? Or, not at all, since we are measuring some fixed response based on the gamma multiplier? Or, I am lost, here's the common/best technique: . .?
5. In the ..Practical Guide to Display Calibration.., Section 3, Color Gamut (which is sequenced after Section 2, Grayscale Tracking). A couple of parts are confusing me here. One, I am not currently using a VideoProcessor, so is it a moot point, skip to the next step in the workflow -re-check (visually) the brightness/contrast/luminance/color (saturation & hue)? What I think confuses me here are two things:
In Section 4, Picture Controls, 4. Adjust Color: it states that Earlier, we adjusted the color by taking measurements through the meter. Now, at this step, we do further adjustments by using a visual blue-filter technique. If I skip this step does it impact the White Balance? Hence, I need to either adjust the initial saturation/hue by taking measurements or do a visual setting of saturation/hue with an SMPTE and blue filter at this point to get a more accurate white balance correction?
The reason I am asking this is that in the newest version of CalMAN 4.5xxx (my current version with updates), the Color Gamut is in the workflow before the Grayscale (in the Practical Guide it is sequenced after). I think this is what really made me question skipping the step, but I not sure if I should do this visually or via measurement, to ensure the most accurate grayscale adjustments.
Side issue: Neither of the Blu-ray discs options that come with the C6 kit have 75% Primary & Secondary individual colors that I can find (JKP DVE Basic Blu-ray or Spears & Munsel Blu-ray). It seems like since I have one system that is currently 720p, the
AVCHD is great for my not yet having graduation to a pattern generator with all the pattern resolutions I might need.
6. Here was a question I was posing to DisplayMate. Also, to SpectraCal, but haven't gotten back anything yet. Maybe you can shed some light on it. NON HTPC: if the USB drive were plugged into the monitor, then how would one switch patterns? They told me to contact SpectraCal. Also, if the DisplayMate were USB'd in to a laptop, which has CalMAN on it and HDMI out, would this possibly be a way to accurately calibrate a display? It would be very interesting to have the patterns local to my laptop running Calman and my C6. I have so much catching up to do, it seems simpler to ask than exhaustive research online to keep trying to figure out what works with what sometimes.
7. There has to be some sort of guide to what all the settings do and are intended for in CalMAN 4.xx, is there a copy to be had?
Gotta love the quest.... T.
