I am new to lightroom, but so far I have been able to understand the program fairly easily. Today, I was editing a photo in the develop tab and used the "sharpening" editing tool. The photo looks much better this way in the develop tab, however, when I switch to the library tab the image shows up without the "sharpening" component of the edit. Everything else is as i edited it, ie exposure, contrast, etc. Only the image has not been sharpened. When I export the image, it does not show up sharpened either. I did some reading and checked to see that my computers color balance was correct, which it was. Any help is appreciated!
