In Nikon cameras, it is a press button, once you press it, it start recording and again you can stop recording by pressing it again. This button is very small with a red indication mark on it.

Auto Mode is marked as Green mode on the Dial button, it capture images automatically means the camera will decide the iso, aperture, shutter and everything the only correct function of this mode is to expose the picture with correct exposure, if you are shooting in the dark, it automatically project the flash on the subject and expose the image.

5. Live View Button

Some cameras have a switch, others a button, but this locks the mirror in a DSLR, blocking the optical viewfinder and allowing you to preview your image directly on the LCD screen. This has limited use for still photography, but you must be in live view to shoot video. Mirrorless cameras are always in live view, so they won’t have this switch.

6. Exposure Compensation/ Aperture Button
exposure compensation

It is used to compensate the exposure of the image, for example if the lighening condition is too much, then we shift to negative side of the exposure and in contrast we use positive side. And in normal condition, even most situation it is nearby 0.

Most entry-level DSLRs make do with a single command dial which, by default, will control the shutter speed when in manual mode. If you want to control aperture, you need to hold down this button. If not in manual mode, this button allows you to adjust exposure compensation — that is, make the image brighter or darker while still letting the camera make its own decisions about which settings to use to achieve that.

7. Command Dial/ Shutter Dial

Command dial is used to increase or decrease the shutter speed, it is also used for aperture control, by keep pressing exposure compensation button and then moving the command dial.
