									How to shoot high-quality video using your smartphone

New phones come with cameras that can shoot videos in high quality, but it does not
guarantee your film was successful. Here's our guide to a successful photography
using a smart phone or pocket camera.

Justice is known in photography is "the best camera is the one that is with you." It
said nice, and very often true: When it comes to documenting the most important
moments in life, the camera's first duty is simply to be there at that moment,
everything else is a bonus. Small cameras and light to carry, smart phones, most of
which include camcorders, are pockets and wallets - always within easy reach.

But there is a big difference between documenting an important moment in his life
and photography. Too often, the videos produced cheap video cameras and
smartphones are videos shaking, faded, grained and with correct exposure. However,
with the right tools and techniques, you can raise the level of the video clips on your
smart phone significantly.

Photo limitations

Before you can overcome the limitations of the camera of your smartphone - you
need to understand them. What distinguished cameras and camera phones and large
high-quality video? After all, the two cameras share the same technical basis of lens,
aperture, sensor and software, and both cameras at resolutions of 720 or 1080.
However, the video produced from each is significantly different.

The most important difference between the smartphone camera and professional
video camera is the image sensor. While video cameras, sensors come in sizes of a
half-inch, two-thirds-inch (measured diagonally) and a 1.1-inch sizes, sensors for
camera phones tend to be much smaller. (IPhone 4, for example, has a sensor size of
0.31 inch for images and videos, which is considered a relatively large sensor
phone). This fact of great importance: the role of the sensor is to collect the light, and
easier to collect light over a large surface area. As a result, smaller sensors have to be
very sensitive to light, which decreases the color quality, image distortion increases
and the result sometimes is very clean image, or in the jargon: a complete picture
"digital noise".

The second main limiting feature of the phone is the camera lens. Instead of the large
zoom lenses that are professional video cameras, phones and small pocket cameras
have fixed optics. Usually these lenses are not sharp, not particularly good the most
important thing - collecting light and transferring the sensor. Worst of all, these
lenses can not make a true optical zoom (digital zoom does not count).

Tricks of sensors

Marty Martin, director and cinematographer from Los Angeles, plain photography in
a professional environment with the highest level of equipment. However, almost
immediately after the launch of Apple's smartphone, he used it to record video - a
clip for his friend Steve phallus. "Since I was doing the first time in the cinema,
always recited one thing," says Martin. "It's not the tool, but only the person behind
it."

The video was created was impressive, but Martin knew immediately what are the
limitations of the camera. Above all, he remembers struggling with rolling shutter, a
phenomenon that causes waves effect video clips. This is because the sensors used in
camera phones recorded by scanning each frame from one side to the other with a
flourish, and record the frame at once. If something in moving quickly, or, more
likely, if each frame moves as camera shakes, markedly distorted image (an extreme
example of this effect is the close-up, using a smartphone, the strumming of a guitar
string or a fan spinning).


To avoid the rolling shutter effect, have to stabilize the camera. If possible, you
should put it on permanent status. Many pocket cameras have a tripod connection, so
investing a tripod or Bmonofod miniature, definitely worthwhile. There are devices
that can function both pusher and help prevent vibration video clips taken freehand.
There smartphones tripod connection, but you can buy packages including phones
with tripod connection (following guide will offer some alternatives "do it
yourself").

For filming video of his friend Martin took the issue to the extreme stability. "Really
I limited my range of motion," he says, which was the key to the success of the video
clip. Most of the scenes were filmed in a completely static, which almost abolished
the effect of rolling shutter, and created the impression that the video camera filmed
much better.

If you absolutely must shoot free hand and do not have any accessory stabilization, at
least stick to some important rules. Hold the camera firmly with both hands - loose
touch will take a shaking. Move the camera slowly, and turned the camera with your
whole body, not just with your hands; suffering almost no camera movement speed,
but camera phones even more difficult problem. Finally, if you are using a smart
phone, turn the device and hold him as he is horizontal. This way will be easier to
maintain stability and ensure that your video will be shot in the right proportions.
Video would not look good with huge black bars on both sides.
Smart video for smartphones


One. Overexposure

The sky is white, although they should be blue.

Solution: If possible, take pictures on a cloudy day. If shooting indoors, no direct
light source.

Two. Rolling shutter

Tent-pole seemed to be bent; areas in photography look compressed.

Solution: keep the camera still, or move it more slowly.

3. Noise in the image

Grained shadow areas.

Solution: Try to compare differences lighting, or use editing software with the option
Lnicoii noises photography.

4. Color temperature

Child's skin tone photography farfetched.

Solution: Make sure that the sources are the same color light (incandescent lamps /
fluorescent / daylight).

5. Poor composition

The child is at the center of the frame badly.

Solution: Learn to work with the system of thirds, move your subject to the left
frame.

Exposure control

Cheap lenses and small sensors make it very difficult on any topic correct exposure.
Fully automatic shooting modes make this phone cameras usually easier to control
the shooting environment than your camera settings.

Photo out to be the most successful on a cloudy day or in the shade. Cheap camera
sensors have a low dynamic range, meaning they are not able to record drastic
changes in the same frame. Too much light will flood the camera, with a clear sky or
reflections that make the rest of the frame to be dark. If impossible to avoid the
blinding sun, a photographer from point raised. This will ensure that the sky will
remain mostly outside the frame, light gauge your camera will measure the subject
and the dazzling sky behind.

Photo Face gives you more control, but raises new problems. To illuminate your
subject from behind or directly in front; Use soft lighting (lamp with shade) if
possible, or light side. In any case, make sure there is enough light - small cameras
and phones produce bad results in low light. A simple work light is directed to the
wall and the light reflected from it can turn any photo on a dark and dim tastefully lit
scene.

You will also need to consider the color of light. Cameras adapt automatically to
compensate for the color, or temperature of the light. Source of natural light tends to
vary blue (or professional language - cold), whereas most domestic lights are very
orange (or very hot professional language). Open window at the burning lamp can
give your subject a blue or yellow tint, depending on which camera focuses light
source.

The basic rules

Some rules apply to all types of camera. Note how is your subject in photography,
and do not always obvious. Law of thirds, which cuts the image of a 3x3 grid, will
help you build a more interesting compositions. Try to place your object in places
and not just the center of the image.

Watch the actions of your subject and you have room to move. Also, if someone
turns left or right, move it to the opposite side of the frame. If you can not put the
whole body of the subject, try to cut natural cutting line, such as elbows, knees or
hips. For more ideas and examples, it is recommended to visit video sharing sites
such as YouTube network. You'll find countless examples of films many talented
photographers from around the world.

Video editing has become very simple with the advent of simple editing software like
Windows Movie Maker or iMovie and certainly can make them videos of good
quality, or improve bad videos. Initial tendency when taking the phone may be
recording short segments, in order to avoid the need for editing. Remember it is
always better to shoot more and edit later. There's plenty of storage space in today's
phones. Besides, the only way to make sure you do not miss the decisive moment of
the football game is to keep your child and record all the time ... Takes a few seconds
to make out a face missing or unsuccessful. But you can not edit in something that
was filmed.
