If you have a new Retina screen Mac Book Pro (13inch or 15inch), and are a member of the Adobe Creative Cloud or have Photoshop CS6 stand alone then you can take advantage of this update to Photoshop CS6 & Photoshop CS6 Extended, and fully maximise your editing potential with this Retina enabled version of Photoshop CS6.
The differences are incredible, here is Photoshop CS6 before the Retina update
now the Retina enabled version
You are able to see the incredible difference between the two versions, just by looking at the icons. Over 2,500 icons have been completely re-created for this version of Photoshop, it looks beautiful.
If we look at a 100% view of the same image
in the Retina enabled version you can see that more pixels can be displayed at 100% then with the non retina version
You can quickly to zoom to 100% using the key stroke combination CMD+1, there is also a 200% available on the View menu.
If for some reason and possibly for a particular job you need to work in Photoshop CS6 at the original non Retina resolution, you can do. If you right clicking on the Photoshop CS6 application and choosing the “Get Info” option, available in the dialog box is the Low Resolution check box.
If you check this box, and close Photoshop CS6 (if it’s already open) and re-open, Photoshop CS6 will will open in the original low resolution version.
