Question using Adobe RAW.

Can someone explain to me what the 2 arrows above the histogram mean when it changes colors. Ive seen it change to red, black, blue and yellow.

I don't have my PS with me at the moment. If you hover your mouse pointer over one of the arrows does a "tool tip" pop up?

At any rate, the one on the left should be to show/hide shadow clipping and the one on the right should be to show/hide highlight clipping.

You can check this by clipping on one and then pull your exposure slider to clip either the highlights or shadows, and look at your image preview.

They are clipping warnings. The color will indicate what channel is clipping. White and black mean all channels are clipping.

^ thanks x2
