I'm just getting started with it and I'm having an issue... Whenever I crop something, it totally kills my image quality. I couldn't tell it in the LR program, but I uploaded a few to facebook and the ones I cropped all came out REALLY grainy and horrible. Looked like I had to shoot them at ISO 8-million or something... Just really pixelated and gross. It was only on the ones that I cropped, and that was the only difference in processing from the rest, so I think that has to be what's wrong. But how do I crop and not have it totally kill my pictures?
ETA: I'm really liking lightroom so far for my purposes. I am NOT loving the crop tool here though... I much prefer the photoshop version. I'm not sure why they had to weird it up in LR...?
