Hi all, I'm checking out Olympus Viewer 2 that came with my E-PM1. I usually use Lightroom 3 for RAW post-processing. One thing that's got me stumped is that when I tried to align/rotate the image to fix the horizontal level ("tilt" option in the software), there's nothing on the screen to guide me by. Lightroom superimposes a square grid on the image to help with this. Is there a grid feature that can be enabled, and if there isn't, how do you guys tilt the image? Just eyeball it? Thank you in advance, Hyun.
