Shadow Detail

post #1 of 7
Thread Starter 
Hello, What are some key points to judging shadow detail ? ex:black suits, visible texture/ folds. Can anybody give examples of what too look for and how do you know if you are seeing too much shadow detail or not enough once the set is properly calibrated with a meter?

A meter is not going to help you set your black level. A pluge pattern and your eyes will do that part.

I use the Light Illusion CalImages - the BrightnessCal image is a good one for blacks and shadows.
(Pluge is only for black level)

hungro if your talking about cable tv every show are filmed differently - some shows the blacks are dark black, others lighter black...other thing is when there's a black object on a white screen the black looks crushed(I'm referring to plasma), not sure if this fixable.Ive adjusted brightness setting so on certain middle to dark scenes with not many big bright patches( not the black objects,more the overall screen gamma) so it's bright but not too washed out.I use rgb which is different from ycc..the cms affects the shadow detail....another thing is when you got tv looking good it can take a couple of weeks watching the tv before you notice a problem.It comes down to how it looks too you,and it's impossible to get a perfect brightness setting as every show is filmed differently.

I know that by watching the home theatre geeks show you can't accurately calibrate for cable/broadcast. I am talking about when viewing refrence material on blu-rays.

If your display is properly calibrated, then you are seeing all the shadow detail that you are supposed to be seeing ...

Except ...

This means all your gamma stuff is tracking correctly too ... as too dark gamma on the low end will hide shadow detail ...

The added issue here is that not all films are mastered to one specific gamma number. It was only a few years ago when they finally adopted one specific gamma number going forward. Prior to that, we have 60 years of programming that could fall anywhere between 2.2 - 2.5 - 2.6.

It doesn't say on the box of any movie what the "gamma" is for that film.

You can only do so much. That's life ... move on. smile.gif

BT.1886 was formalized, but even now it's still not widely adopted. Also BT.1886 is not a gamma of 2.4, the formula is significantly different than just the simple power formula.

So even now, you're just making a best guess to what gamma used during mastering.
