I've been batching up some photos to get ready to post and was using Adobe Lightroom to resize them down to the proper dimensions. Surprisingly, Lightroom isn't actually very good at that. Even with all the sharpening turned off, I kept getting halos around areas with high contrast. I couldn't figure out what was going on because if I export the image full size form Lightroom and then do the reduction in Photoshop, it looks fine. I've done some digging around and according to this pote it appears, this is just the way Lightroom does it, and there is no override. Here's hoping they work on this to make it better. As a commenter mentions, Lightroom is supposed to reduce the number of steps in the workflow.
