Photographic lamp socket

You may need to check the focal length and aperture of the shot.

If you want to shoot the feeling of silk and loose skin, the focal length should be very accurate and the aperture should be large enough to highlight the subtle phenomena of the object.

When the thumbnail looks ok on the machine, it is suggested to add a tripod. It may be because the hand is unstable and the shutter is not fast enough. It causes slight jitter, which can't be felt in the small picture, and even the slight jitter after amplification will be affected.
