TOO much noise reduction

Yes, photographs should be clear. Noisy or grainy images are not preferable. Because our views are not like them.

To make photos clear, I learned how to use noise reduction on Photoshop lightroom.
This function is great. Well organise. But, if we use this too much, images lose sharpness tremendously. Once lost detail, photographs seem to be slippery.

This is one of difficult points.
