- Edit My Images
Are you aware that FRV has three levels of sharpness (including no sharpening) to choose between, and you can customise how sharp the two sharp settings are by setting them in the preferences.I've stopped using FRV. Images don't look the same as in lightroom - they would often appear unacceptably soft but were fine with LRs baseline sharpening.
Hitting "S" toggles round the three settings or you can click on the "USM" button in the lower tool bar. There are also visual assessments of sharpness by clicking on the E or D, which work a bit like focus peaking in cameras.
Having said that, I don't cull in FRV, but use Photo Mechanic for culling with FRV on a hot key in PM to open files in FRV for a more detailed technical assessment of "difficult" images.
