Hello! When I edit Sharpness in the DEVELOP module in lightroom the edit shows up. When I click back over to LIBRARY the edit Sharpness is all gone. What is happening?

  1. Check the graphics card driver  - Install any updates.
  2. Load LR and choose Library Mode.
  3. Click Edit > Preferences on the menu bar.
  4. Choose the Performance Tab. Remove the check from the [Use Graphics Processor]
  5. Check/Change the Preview size.  Click Edit > Catalog Settings on the Menu Bar
  6. Choose the File Handling Tab. Make sure the Standard Preview Size is set to "Auto" and the Preview Quality is set to "Medium".
  7. Click Library > Previews > Build Standard Sized Previews on the menu bar.
  8. Exit out of Lightroom.
  9. Start Lightroom and try again. If this does not solve it, let me know!!!!

The previews you see in Library & Develop are actually different from one another.  In addition to Joel's suggestions, I'd recommend doing a little reading on how Lightroom creates & uses previews.  Here are a couple references that may be helpful -

As mentioned by Tom Mickow  the Library and Develop module previews are created differently. The Develop module uses less accurate, but faster nearest-neighbor interpolation to create Zoom previews less than 1:1 size (i.e. Fit, Fill, etc.). This was done to speed the real-time image rendering during editing in the Develop module.

The Library module uses a JPEG Preview file that is created with a more accurate Bicubic interpolation. When viewing images at less than 1:1 Zoom view such as 'Fit' a 2nd interpolation is applied to exactly "match" the preview window size. This 2nd interpolation causes a slight softening of the image detail. To prevent this from happening do not use the 'Fit' or 'Fill' Zoom settings. Instead use 1:4, 1:3, etc., which are the pyramid Preview sizes already created. The Library and Develop module images should look near identical. Just keep in mind that Detail panel adjustments should only be made at 1:1 View, which is the only Develop module Zoom size that provides accurate image rendering.

If after following these instructions you still see a difference between the Develop and Library modules it may be due excessive Sharpening and/or insufficient Noise Reduction. This can happen when processing High ISO image files (800 and higher) or images that are very underexposed.
