I just got Lightroom 5 last week, and I'm still getting used to it as well as reading Scott’s Kelby’s The Adobe Photoshop Lightroom Book for Digital Photographers.
I've always used Photoshop, but I noticed when I zoom in on and image in Lightroom, it looks very grainy and pixellated.I haven't read the book all the way thru yet, but is there something in setup that I missed maybe ?
