Is there an easy way to see where the blown highlights are in an image in Photoshop CS2/3?
In the Adobe RAW converter, there is a nice little check box called Highlights which will turn all blown areas red. Is that same (or similar) functionality available for any image open in Photoshop? |

A quick-n-dirty way is to add a Levels adjustment layer then hold the Alt key while clicking on the little arrows at either end of the histogram, the right side showing blown highlights (if any) and the left clipped shadow detail. Dragging the arrows while holding the Alt key shows the effect of "pinching" the histogram. Note also the color displayed while holding the Alt key indicates the intensity of blown higlights or clipped shadows and the further in you drag either toward the middle, the more reds and yellows you'll see.
You can also use the Curves adjustment layer to achieve a similar "indicator" to that in ACR.

There are couple things in PS that you can use:
1- View->Gamut Warning
This displays out-of-gamut areas shown in grey. It is a combination of both the highlights and shadows you see displayed as blue and red in the RAW converter. Where you see grey there can be "blown" highlights.
2- Use the eyedropper tool
Among other things the eyedropper tool displays the actual Red, Blue and green color values in the info tab. 255,255,255 is pure white. If you look in an area where there SHOULD be detail but all the eyedropper displays is 255,255,255 then you have "blown" highlights in that area.

L()L, Ok, it has something to do with the 'recovery' slider. I know that will help to fix the area... but ... hmmm I found the video off this site L()L where they had all those links before? L()L well it looks like there is tons of good advice so I will just run before I make it worse L()L

It's not like it is in Bridge, but you can view them with "Threshold" in Photoshop.
In photoshop, choose Image/Adjustments/Threshold. Then move the slider all the way to the right, those pixels are hot.
Hope that helps |

Thanks for the effort, Andrew! Mostly I was giving you trouble. I think what you are remembering is in the RAW conversion process.
Thanks for all of the tips everyone. I think Threshold is probably the closest to what I was looking for.
Thanks!

The gamut warning is going to give you a good clue that something is wrong.
