in this new version, I can not find the intensity value to control exposure (Post Processing)
tutorials and documentation controls the exposure to that value
any ideas?
thanks
-
there is the exposure compensation, it is the same, only with exponential scale

ok........it is the same
but after a certain limit, the picture will not change their exposure
____
for example:
Exposure Compensation : 0.1
Highlight Compresion: 20
is exactly equal to
Exposure Compensation : 0.01
Highlight Compresion: 100
____
the image is being burned
thnx

Like in case of camera exposure compensation, you are supposed to go into negative values, so try for example -1.0 or so.
Having exposure controlled by exposure compensation parameter may be sometimes confusing as negative values are not usual in such cases, and i pointed that out to keymaster on several occasions, but he insists having it that way until photographic exposure controls ale implemented.
I usually start with value of -2.5 for exteriors.

yea............was that
negative values!!!! for exteriors
great and thnx

and gamma 2.2?............where is it?

And, of course, you should NEVER EVER under ANY circumstance touch gamma value... EVER!
NEVER EVER!
EVER!
AND FOREVER!

OT//
location of that spinner should be none of your business if you want to keep a simple, high-quality workflow :D
-
Why it is impossible to use gamma differing from 2,2?
Here example: In your opinion what it is better?

In my opinion it's gamma 2,2.
And you can always alter it in post.

It is not impossible, but the JPEG/PNG assume gamma 2.2. If you use different one, you are not doing physically plausible rendering. Of course there is the artistic licence, and only the result counts, but it is the same type of fake as ambient occlusion, disabling GI/faking it with invisible lights, etc., so I would think twice if I cannot get the desired effect in some other way ;)
-
You know, before all the physical correctness are customers that principle to the bulb whole tinsel with physics - they need to sell a picture.
My employer chooses a picture with a gamma of 1.0 and I am with him in this match because it is much more closer to what I see with the eyes.
-
Actually what you see with eyes is closer to gamma 2.2 and gamma 1.0 is more like an image captured by an electronic device like digital camera.
