CS3 question? ...again

I am working with the threshold adjustment. I am marking the black and white point using the shift key.
My problem is.... how do I make my selected point go away after I am done???

Anyone know?

Kim: Try this:

Hold the shift key down, click on the point you had previously created and drag it off the canvas.

Did that work?

Hmmm....well, I thought that worked for me. However, your shift-alt approach is clearly right because a little pair of scissors magically appears and "snip - it's gone"! :D

yep, scissors for me too.

We are learning color correction in my class. Use the threshold. find the black point, use the black dropper in either curves or levels, then try the white. I'm not doing well with the white. She didn't show us how to mark the point but I remembered. I just couldn't remember how to make it go away.

Kimi, how is your class going? Is it worth the real price?

Kimi, I recall reading that when selecting a target area for the white point, it shouldn't be a spot that's completely blown out (i.e., RGB=255, 255, 255). If you find an area that has at least a smidgen of detail, it works much better. Using the Eyedropper tool with the Info window open can let you quickly scan your photo for good target areas.

yeah, that is what we are doing. Using the info box to check for color cast. I have been careful not to find blown out areas but I haven't found a photo yet that has worked with the white point. Now I did learn a really cool way to find the gray point. Might have to share that as a homework down the road. :biggrin:

Kim:
Do this if you have not done it yet:
1-Open Curves and double click on the shadows eye droper now enter on
R -10
G -10
B - 10
Click OK and now do the same thing on the white eyedropper and enter click OK
R - 245
G - 245
B - 245
Now go to the midtones and enter
R - 133
G- 133
B -133
Click OK to set those values.
Close the curves dialog you will get a Warning dialog that reads "Save the new target colors as default? say Yes.
Now with those values it will be much easier to balance color.
hope this help.

Thanks Don, I am going to give it a try.

but, I want to understand. Why are we setting to these values?

When black is 0, white is 255 and middle gray is 128? Can you explain on layman terms so I will understand?
