Does the ppi resolution setting have any effect on how Output Sharpening works in exporting from Lightroom? I understand that the ppi resolution setting has no effect on the image pixel dimensions, but the does a value of 150 or 300 or leaving it blank make a difference on the result of Output Sharpening?
My understanding is that Output Sharpening is dependent on output size, but it's unclear to me if it's dependent on and a function of the pixel dimension size only or the actual print size which would take into account ppi.
