On this super quick video tutorial portrait photographer Nathaniel Dodson (from the website tutvid) demonstrates how to zoom the entire window of an image quickly in Photoshop.
The following is a cool trick that can be useful to some users in some situations. It can help you keep many images open in a more organized manner (supposedly at least) and can assist you in working on several images simultaneously.
So how do you do that – very simple – edit>preferences>tool>tick [zoom resize windows]. That’s it, you are done. When you want to return to the normal way the zoom key works just do this again and un-tick this box.
