You have more control over sharpening your images by shooting raw files than by using an in-camera sharpening feature.

Sharpen up
Q
Does my Nikon D500’s Sharpening adjustment setting in Picture Controls really have that much of an effect?

To answer this, Joe, we need to clarify the difference between getting your image sharp by accurate focusing and
‘sharpening up’ an image by the use of processing. No amount of software sharpening will truly make an out-of-focus photo in focus!
Accurate focusing therefore remains critical, coupled with the right choice of aperture that governs the band of sharpness (the depth of field) within your image, and a shutter speed that is fast enough to freeze any motion from your subject or the camera itself.
Your Nikon D500’s Picture Control settings enable you to select a ‘style’ of image that you like – whether that’s Standard, Neutral, Vivid and so on. Within each setting you can make further adjustments to how the camera processes the file. Increasing the slider for Sharpening will only apply extra contrast to edges and won’t make any difference to the actual point of focus and amount of throughthe‐image sharpness created by your aperture choice. If you oversharpen the image, it can also degrade its quality.
To be honest, the best way to ‘sharpen’ an image in processing is generally to shoot raw files rather than JPEG, then take control of the amount of sharpening applied in the post-processing software you use.
If you are shooting JPEG, a small amount of additional in-camera sharpening might help the image a tiny bit, but I wouldn’t advise pushing it too far.
