Halve way step.
the paintings are behind glas.
so i had place a whitepoint on the paper and no the brightest places.
Blacpoint to the left dark stroke. the girls dark hair is not so black.
You could place a neutral on the black of the girls hair ( black could be a neutral) but I have placed it  on the grey spot.
I always wil see a info of the points so that I can judge it.

Good job Fritz..You might be able to add some saturation to the image it still has room for more...

Greg,

I understand.
I have seen them all, And I find some over-satisfied.
It is a question of taste.

My computer on wich I do mostly the video was vroken.
The powersupplie was gone.
I had to go to town to buy a new supplie.

It is really a matter of taste..the example was used to show the ease and power of the LAB slider and the L channel.

Greg , indeed!




Mostly , I have problem to met a picture.
Say, you make a lot of pictures and the question is everytime: how do I approach these pictures.
Often, perhaps the most, I have underexposed photo's, or the contrast is to low.
So, the lake from Mike is such one. ( not the contrast) My personal goal is to make it so, it is reasonable to see.
I use cm for a long time now, but it is not in my fingertips.
When is it ?

Fritz,

underexposed, really dark or muddy images are always a challenge.
There is often a need to use PS tools first to try to get the image into better shape.

Try CM.  If you cannot get the image where you want it you could try a screen mask in PS maybe even two.  There are many techniques for lightening the really dark images.

Most of it can be done in CM but I have run into a few that need  more help.

Greg,

I know what you mean. P.S E has a possibility to make the pictures lbrighter.
there is a mask in that possibility.
But my goal is to do it in CM without using PSE possibilities.
I understand from your answer that it is not always possible to it in CM.
0n this moment , i have not a own recent made underexposed picture.
But i have made a lot of pictures of my grandchilds drawings.

I post here one.
look at the histogram.
U ahve used the flash, and  taken the pictures in bright light.

From looking at the image and histogram I would say that this is an exposure problem.

Was this a Auto-exposure? or Manual?  If it was Auto the flash fooled the lightmeter.  If it was manual you might be misjudgeing the EV of the flash...

Either way this one can be saved in CM with a few simple changes in a Lab curve....It is not severely underexposed enough to be a problem in CM.

greg,
it is auto-exposure.
S, how can the flash foo the lightmeter? the duration of the flash is about 1/100.000 sec I think.
For your eyes  seeing it, it seems longer.
The picture is not a problem for me to do in CM.
But i have a lots of them, taken on several days and light circumstances and  I asked myself , why the contrast is so low.
In normal ways I could plus the EV extra. But in this situaitions it will not help.
So, also underexposed pictures are sometimes the possibility with extra this phenomena.
