How to set up Nikon p90 micro camera?

Nikon P90 is a digital camera for short film shooting. When m is in gear, it means manual gear, and you can adjust the settings such as aperture speed yourself. When A is the aperture priority, you set the aperture, and the speed camera automatically adjusts. S gear is the first speed.

Micro-single contains two meanings, micro, compact, single-lens and replaceable single-lens camera, that is to say, this camera is small in size and its imaging quality is similar to that of SLR. That is, a micro camera with SLR function is called a micro single camera. Micro-camera is between card-type digital camera and SLR camera, just like netbook appears between notebook computer and smart phone.
