Suggestion: how about a way to calculate the area of a selection as percentage of entire image?

I mostly do bird photography, usually have a small amount of the subject in a large image. I would like to be able to determine what percentage of the total is occupied by the subject. Currently I make a selection with Select Object and see where the markers lie on top and left of screen, then do a rough calculation based on presumption of rectangular sized object compare to full image. My percentage calc is therefore incorrect as birds are not cubes.  This image is about half of one percent of entire image area, subject about 200 feet away. ( It is a Gadwall female taking off)

I use a Nikon D-850 with 80-400mm lens, usually at long distances. Knowing what percentage of total image is the actual object would help me in choosing what effort to spend on post to sharpen and crop for decent results. Dave Grainger birdsbydave.com

Go to "Window>Measurement log", make a selection and see, if that helps.

Thanks! It took me a while to read  and understand about HOW to use the Measurement tools in Adobe's pages, but that was exactly what I needed! In this example I discovered, using the Measurement Tool, that the area of this Gadwall as a percent of the total image was 0.39%, which makes me feel pretty good about the quality produced by the Nikon! The bird is cropped out of the overall image... Appreciate your assistance!  Dave Grainger
