I have only been working with Lightroom a couple of days and today I started playing with Detail and sharpening. In Develop after I made all my corrections and go back to Library all the corrections were saved EXCEPT for the sharpening. Color, exposure etc...all looks same but for some reason the sharpening is not being saved. Going back from Develop to Library the focus is no where close to what I corrected. I don't know what is going on, I confess I'm not a big computer guy but I called a buddy whose been using Lightroom for years and he's stumped. I hope somebody can help
To apply and assess sharpening (and noise reduction) reliably, you have to view the image at 1:1.
Any other magnification (like Fit view) will be inaccurate and misleading.
And Develop and Library will not display sharpening and noise reduction identically in Fit view, but they will at 1:1.
