How to know one single pixel RGB and transparency values precisely in Photoshop? Using eyedropper tools I seem not to be able to do that, i.e. it shows RGB=(0,0,0) on partially transparent pixels ("all layers" is selected in options).
My image has layer options like shadows and glowing and transparent areas.
EDIT 1
Probably the reason is because I use layer effects?

Set the Eyedropper tool to Point Sample, and Sample All Layers:
Then set the Info panel to show RGB on one side and Opacity on the other:
(this is done by clicking the icon in each section to open a menu)
