Checking Exposure of a specific area

(ej) #1

Is there a way to make a selection in an image and then view a histogram for that specific area in order to check the exposure?

Thanks

No, not at the moment :frowning:

In what context or situation could this be useful?

What happens if you temporarily crop the image to your required area?
The histogram ought to be specific to the cropped area

You don’t even have to crop. The histogram is updated from the area defined by the crop marker rectangle whenever it is drawn, resized, or moved.

I thought it would be helpful when I am practicing using fill flash outdoors. The ambient exposure may be intentionally underexposed from the subject. But I have messed up plenty of times and underexposed the subject while I was using an ND filter. It would be helpful to be able to see the histogram of the face only to get an idea on how much I underexposed the face.

Thanks

Wow, I didn’t think of this. Thanks for the insight. I will give it a test today.

Thanks.

Yes, I think I see what you mean. The histogram gives important information but is not a “tool” to correct something. If it is to compensate for underexposure (or overexposure), one can try with Control points or with Smart lightning - Spot weighted (or even both).
