Is there a way to make all layers visible in Photoshop? Is there a quick way to do this, for example, short key or script?
I’m guessing you have a huge number of layers:
The fastest way is to click+drag over all the layer eyeballs, this works in CS5 at least. Note that visibility changes are not undo-able, i.e. they don’t show up in history
A better suggestion for the future; get used to organizing layers into groups, then you will have far less ‘points’ to turn on/off layers.
There are also some cool layer shortcuts here
