Avoid these mistakes in your Video

1. Things growing out of peoples head

This is a compositional error that comes from not paying attention to what's in the background. Trees, poles, and even bits of other people will appear as horn or odd growths. Always keep an eye on what's behind your subject and how it affects what's in your viewfinder. Also look for things like telephone wires that seem to go in one ear and out another.

Changing your angle slightly can fix these. If you're completely unable to move, you can try lowering up your f-stop to blur out the offending object, or zooming in to crop it out of the frame.

2. High Noon

The sun directly overhead on a cloudless day presents some of the worst, most unflattering lighting conditions. People's eyes, recessed in their sockets, get lost in shadow which become great black pools.

There are two ways to combat this - add more light, either from a light or a reflector - or move your subject into the shade.

3. People Eating

Simply, avoid shooting people while eating.

4. Shooting in the Office Lighting

The overhead position doesn't give much fill to the face and like the high-noon lighting of the sun, people's eye sockets get dark.

When professionals shoot in office buildings they have a number of strategies to combat this - one is to turn off all the overheads and light the room with their own equipment, another option is to move your subject into window lighting and let the sun fix things. A third option is to color correct the florescent with gels and add some fill from a tungsten lamp either through a light modifier like an umbrella or a softbox or bounced off of a card or wall.

5. Low angleIf you're shooting up at a person on a stage, move back, raise your camera, or move to one side so that your subject's nasal passages aren't the main focus of the shot

6. Litter in the Background

As a general rule, try and keep your background uncluttered.

7. Shooting into the Sun

Backlighting a subject without lots of artificial light on your side of the subject will lead either to an extremely blown out (too bright) background, or to your subject being silhouetted.

If possible move your subject or your camera so that your subject isn't darker than the background, if not possible, add additional light to his/her shadow side to lower the contrast.

8. Wrong White Balance

Different lights are different colors - in bright sunlight a sheet of typing paper looks white, under fluorescent lights it may look slightly green and in tungsten lighting it will have a reddish cast. The "white balance" setting on your camera tells the sensor what color light you're shooting under.

Most cameras have a number of pre-set white balances for sun, shade, fluorescent etc, and also an "auto" mode where the camera will try and guess what the light is.

 9. Children and Animals from an Adult's Eye Level
 When composing shots of kids and animals, get down to their eye level. Capture faces, not the tops of heads.

10. Automatic Modes

You can let your camera set and correct the exposure and audio levels, but it’s never going to be as good at this as you are. The camera can't tell between white and black and their different reflective properties will confuse the auto exposure.

Likewise, the automatic gain control can't tell when a room falls silent, or the speaker gets further from the camera and may end up giving you a lot of ambient room noise trying to pick up a voice that isn't there

Conclusion

Doing mistakes is not a sin but avoid the same mistakes and learn from them. Everyday is a new learning experience, go out and enjoy your time with your camera.
