I am new to photo editing and Lightroom, but I am encountering this problem and haven't been able to find a solution through searching online. I will edit a photo in Lightroom and it will look great. I will then attempt to export it, and then select email. I started using the standard settings but when the images are received in email, they are very blurry. I then tried making sure that it was sharpened for screen viewing and still didn't help.
What size are the images in Lightroom? I am asking about pixels (width and height), not file size in megabtyes/kilobytes.
What size are the images after you export them from Ligthroom? I am asking about pixels (width and height), not file size in megabtyes/kilobytes.
What export settings have you chosen in the File Sizing section of the Lightroom Export dialog box?
