Hi iimerica, When you crop an image, you are cutting off some pixels, and creating an image that is smaller than the original. That's just what cropping is. In Photoshop, when you scale the image back to its original dimensions after cropping, you are adding new pixels to the image, and PS has some very sophisticated math to do this well. But, you're adding pixels and interpolating their value. The image is irrevocably modified at that point. In Lightroom, when you crop, (assuming you are keeping the same aspect ratio As the original image) you end up with a smaller image as well. But, when you export that image, whether to a file, a printer, or even to edit further in Photoshop, you have the ability to resize it at that point - maintaining the integrity of the original file. Furthermore, Lightroom's crop is non-destructive - you can go back at any time to the crop tool, reset the crop, and you're back to your original unaltered image. Both are valid work flows, but if you are in a Lightroom-centric work flow, you should crop in Lightroom without worrying about the exact pixel dimensions, and scale later in the output process. (I'm assuming minor crop/straightening, and not extreme cropping of the image). Mike
