Count pixels? Help needed!
|

| If I create a black silhouette on a white background in PS 5, is there a way
to find out how many pixels are black vs. white? Maybe some way that PS will
report this value while doing an operation?
(Background: I'm comparing riding positions on my bicycle to maximize
streamlining. The fewer black pixels in the image, the smaller I'm making my
body on the bicycle and the faster I'll go. )

John: This may help: Make a selection of the black portion of the
illustration using any appropriate selection tool (such as the Magic
Wand, with the Contguous option unchecked). Then go to Image >
Histogram and the Pixel count of the black will be shown in the lower
left of the Histogram display. The white pixel count might be done in
a similar fashion.

I'm not sure about PS 5, but the Histogram tells you how many pixels if
you move the cursor over it.
