Hi, Im a beginner with Lightroom. I still have my Aperture library. I imported my last SD card into Lightroom to try and play with it. - It is using RAW as default. In Aperture in why my JPEG first and under it was the RAW and I had an easy option to switch between them. Anyway to have this in LR? - They don't show up in images when I want to change my desktop background (OS X) ... because of RAW? Thank you!
