Threshold or Shadow/Highlight

[mikemeister_admin]

I might be missing something Greg,

I nearly always use the Shadow/Highlight setting as a way of correcting the image.
I realise that this also sets colour in rgb, but not in lab.

Looking at the Gorge solution - lab solution - it is recommended to use the Threshold method because there is no neutral balck/white points.  Why?

hmmm not the way I saw it..from the video Mike starts with the neutral and then thresholds...

You may have missed it...

Ah, I havent made myself clear (as usual).

I was interested in the difference between setting a shadow/highlight via pins or doing it by moving the side of the curve dialog.

Why use the latter in preference to the former in LAB?

You mean using the curve thresholding for shadow/highlight, as opposed to setting pins? Thresholding is easier - no need to seek out the lightest and darkest areas, just move the threshold until you see the pattern in the image. Quick and simple, I use it all the time.

The downside is that when you change colourspace, you lose this adjustment. Pins stay put and are automatically applied to all colourspaces.

Ahh.....

Thanks Derek...

It also helps to find the darkest areas when you are not sure..less hunting around...
I will frequently combine the two..I'll use the threshold to find where to put the pins...
