I have the new 2014 MacBook Pro with Retina Display and just downloaded the latest version of Photoshop. I've found that when creating graphics for the web (buttons, banners, etc), I have to zoom to 200% in order for the size of the graphic to be what will appear on the web. For example, a 600px wide banner appears to be 300px wide in Photoshop (even though it is, indeed, 600px when viewed on the web). I've learned that I have three options:
1) design while squinting to see the very small object on the screen (not really a good choice),
2) check the "Open in Low Resolution" box for Photoshop if I want my graphics to appear to be the right size when designing them in Photoshop, or
3) continue zooming to 200% when working in Photoshop.
My question is: aside from the obvious annoyance factor, which of these options is the best choice for creating the highest quality graphics for the web? Are they both the same result... or am I hurting my graphics in some way by choosing one over the other?
THANK YOU!
