When my Gopro Hero 4 Silver arrived, I was very anxious to use it! As most say, you can use it straight out of the box - true!
I quickly came to find that those 3 little buttons would be very tricky at first to use and maneuver through. My husband would ask, "How hard could it possibly be, it is only 3 buttons?!" Thank you to Mr. Paul, our neighbor who confirmed it is trickier than it seems (at first). lol
Before learning the buttons really well, I had various unpleasant pictures...lol. My face, nose, chin etc. I also had tons of video of the ground while I was walking. When I thought I was taking a Time-Lapse, it was a single shot, or thinking I was taking a still I was shooting video. Many awkward moments with the Gopro. Maybe one day, I will get brave and post some of those!
With that said...
You have your top button which is your trigger button per-say. You will click that like you would on any camera, to take stills, to start video etc.
But it is also used as your choice button when you make selections in menus.To change from Video to Video-Lapse, Photo - Lapse, so forth. You will use the top button to maneuver through each menu selection.
Then you have the front button which is your mode. That front button when held will turn your camera on/off. It is also used to shift through modes - Video, Photo, Multi-Shot, Setup, Playback. Your choice will show on the front of your camera, or Hero 4 Silver has the LCD screen (which is touchable) on the back, you can select through using that.
Then you have a little side button. This will take you into settings of each mode you select with front button.
Your mode will show at the top, example
Scroll to "Video" Mode with Front Button
Then press side button to enter the "settings".
Your setting screen will look something like this
FPS : 15
Low Light: N/A
Spot Meter: OFF
White Balance: 5500K
ISO : 400
Sharpness : MED
EV COMP : 0
You will use the Mode button to scroll down through your options, after you have the area highlighted that you want, press top button each time to change shooting options. Once your option is showing on the screen, then press the Mode button again to go to your next option. Once all your options are chosen, go down to "EXIT" and press top button to start using.
Another feature that is great - while in the "setup" mode, you can press the side button and select to turn wifi on (will drain battery quit quickly if left on). Once you have it turned on, you can pair it with your phone device using the gopro app. This will allow you to use your phone as a controller. If you set up your camera away from you for a shot, your phone will let you see what your shooting. In Time-Lapse you can start your camera from your phone but viewing will be unavailable. You can view while your taking pictures or video.
I have learned one thing about the wifi - when using under water the signal can quickly be disrupted between your phone and GoPro camera. So you either have to keep it shallow or just point and click the old fashion way.
