Nikon D3300 Manual

I own a Nikon D3300 DSLR camera. The D3300 includes a 24.2 MP sensor, includes an ISO range of 100-12800, and includes many different features for different types of photographs. After reading through my user manual, I discovered the functions of a few features that I originally didn't know the use for. First, I learned that the battery life of my camera is 700 shots, which is a significant amount for an entry-level DSLR. I also learned that Mode P on my camera automatically sets aperture and shutter-speed for an optimal photograph. Lastly, I learned that you can use exposure compensation to alter the exposure of a photograph.
