Hi… cropping in LR just changes the aspect ratio. It doesn’t affect the physical size of the photo. To size it, you go to File > Export when you’re ready to print or send it off to some one. There’s a file size section in there.
Matt, I noticed about two weeks ago that the dpi is suddenly limited on export: I usually export at 300 dpi but am now limited to a “range between 1 and 217” ????!!! I can overwrite to 250 but not larger. Help.
