my copy of photoshop cs5.5 has no "use measurement scale" tab on the ruler tool bar. Is this right?
Right. That checkbox was added in Photoshop CS6.
I believe that's only in the extended version of photoshop (cs3 and newer) and not the standard version:
Oops, you're right R_Kelly. I moved up to Extended at the same time as upgrading to CS6. My bad.
Thanks for the correction.
Thanks R_Kelly appreciate that.
Thanks Noel appreciate that.
