Blurry Guides in Photoshop CS5

Photopshop CS5I just started using Adobe’s CS5 this week at work. When ever I install a new version of any software I usually run into a lot of bug and configuration issues, and Photoshop is no exception. If you are a web designer and use Photoshop then pixel perfect precision is a must. When you first use CS5 on your next web mockup you may notice that the guides you set up are blurry. They are about 2 pixels wide and pretty much useless for web layouts.

What’s the fix?

The fix is quite simple and surprising. I was figuring it would be a graphics glitch or OS setting or something along those lines. It’s not though, there is actually a setting for blurry (Anti-aliased) guides in Photoshop CS5 and it’s the default setting.

Go to Photoshop Preferences / Performance. Click Advanced Settings… located below Enable OpenGL Drawing. In the dialogue deselect Anti-alias Guides and Paths. You should now have sharp one pixel guides.

This setting was performed on the Mac version of Photoshop CS5. I don’t know if the same applies to the Windows version. If it does please post in the comments.
