"NX2 and "Show Lost Highlights""


US
          

Using the "Show Lost Highlights" tab, I notice that NX2 displays various parts of an image with different colors, from blue to red to white... Is this the way of demarcating, "nearly blown, slightly blown, totally blown"?

The Histogram would tend to support my theory, but I wanted to check with others who know the program...

Thanks for that. It's much clearer now.

I know it will be a "wonder" if anyone is still tracking this thread, but I thought I would give it a shot. I "googled" this topic and landed here. So, I'm beginning here. Just joined the forum.

Since this tool gives this information in very specific categories, I was wondering where I can read more about responding creatively to the color channel info provided by this tool. Obviously, this is pretty advanced work since I don't see this topic in "quick start" and "quick fix" and more elementary presentations. Maybe working in these channels or knowing this info is only for designers.

But, I would like to read a little more about the story behind the information given by this setting in CaptureNX2. What tools would one use to respond to the info regarding the presentation of yellow in "show lost highlights".

Thanks.

There are 3 methods that I use for retrieving lost highlights but the solution varies with the exposed shot.

If RAW, adjust exposure.
Quick Fix - Highlight Protection.
Quick Fix - Reduce Contrast.

There may be better methods (I will let others chip in here) but one, or a combination, of these works for me.

Though I have not tried it, I believe you could also use a color control point to recover lost highlights as when you use the ALL function in that control point you get access to the RGB sliders and can therefore reduce the values of the ones at 255.

That'll work okay for something that's neutrally colored (bright whites, which will then go grey), but since the control point function can't recover lost highlight detail, colored subjects may end up with color shifts. It can be better than nothing when used in small areas, though.

If you have exhausted the ability to "recover" the lost highlight, you can still address the problem.

With some colors lowering saturation can be used to make blown color less offensive - such as with blown reds in red flowers. This is similar to the idea of reducing contrast.

One choice is to use the clone tool to clone out the problem highlight. If the area is small - an undesirable reflection or highlight, this works nicely.

The other tool is to use a control point to replace the blown color with a color of your choice - typically a darker shade of the same color, but you could also simply pick up an adjoining color using the eyedropper. With this approach you may still need to clean up the edit with the clone tool.
