The camera in question is a Nikon D3200, it features 24 MPx.
I would like to know what changes are brought about on the sensor to enable it to shoot at lower-resolutions.
- Does the camera shoot in a crop mode, ignoring some pixels to bring resolution down?
- Or does the camera merge multiples pixels to behave as a larger pixel?
I'm quite certain the former is correct, however I would like to be sure about this.
