Now, this is very interesting and informative. Wish we could see more of this on UHH...

Wrong...if you do not edit for level as a "smart object" you loose detail and sharpness.

If you work in Lightroom, you do not worry about smart objects or detail or sharpness losses. Lightroom only touches real pixels when you *export* a file or print. You can do anything LR will do, undo it, redo it, do it 30 ways, and there is no degradation of sharpness. Get the horizon angle right, make other global adjustments, export PSD or TIFF in 16-bit ProPhoto RGB color space, and work it in Photoshop to complete, if need be. Only save a JPEG when you're all done.

PS: command J/edit/transform/rotate/check with guides/turn off background layer and then crop out lost area. great opportunity to correct composition at this point with more aggressive crop. done.

I think I'll try that idea!! My horizons always seem to off a little even though I have the grid in my viewfinder! Thanks
Remember that some lenses have some barrel or pin-cushion distortion. You need to use the most central vertical and/or horizontal grid lines for leveling. Otherwise you need equalize the gap distance to the grid line in the two corners. Also, the longer horizontal grid lines will produce a better visual level than the shorter vertical grid lines.

Thank you for that info. I will pay attention to that. I'm glad I shoot RAW & pp in LR. The transform tool is sometimes my best friend!
