So you’ve been working in Photoshop for a while now, perhaps a few hours. Of course, your file has changed quite a bit and you’re wondering if you’ve actually improved your shot or if you’ve just been overdoing your retouching. Well, if you are currently disabling every layers except the original one in order to view this, it’s going to change.
In Photoshop there’s a shortcut allowing you to shut down every layers except one. You have to press Alt (Windows) or Option (Mac) while clicking on the eyeball of the layer you want to keep viewing (the original one). Alt-click again will enable them all back. Now, you can use this trick with every layer you wish, enabling you to easily visualize an adjustment layer on its own, for example. It’s worth keeping in mind because this little shortcut can actually save you a lot of time.
