A lot of interesting plot

pictures today is not lifted professional technique, and smartphones. In contrast to the “reflex” or “Soap”, the phone is always with you. He’s already turned on and ready to go at any time. It was built in camera have time to take all the fun – from the first steps of a child before the fall of the meteorite. Initially, her photographic opportunities are very limited, but there are ways to significantly expand them using freeware tools and small layfhakov.

main problem when shooting a smartphone – a hand shake. Almost always the frames are obtained in varying degrees of blurry. The camera is easy to install on a tripod, but what about your smartphone?

Secure smartphone by using a cradle, branded and compatible derzhalok. Sale and miniature tripod, but if you look for these specific things once, you can do homebrew of the more common items.

Alternatively, you will need a regular tripod, stationery clamp nut and the corresponding diameter. Cap will be more convenient, as his hands tightened. Most tripods thread 3/8 “. The thread pitch on the nut a little not the same, but you can fix it without a problem. To avoid scratching the screen, beneath the foot clamp a piece of paper.

Most of the controls will be located along the long sides of the screen, so it is recommended to strengthen the smartphone for the short side. Once the desired angle is selected, proceed to the software part.


Camera FV-5 (Lite)

This program will be of interest to those who are used to complete control. She carries the maximum interface and logic with the “reflex” on the smartphone screen, offering an array of additional features, even in bypass restrictions Camera Driver OC Android.

The first thing that catches the eye – the full display of all the shooting settings. The sensitivity value in units of ISO, shutter speed and aperture, such as focusing and metering, manual exposure compensation within six stages, the ability to lock it automatically determining and fixing the selected white balance settings. And all this is only the visible part of the iceberg.

are four preset white balance settings plus its automatic detection and fixing.

Metering is selected from three options: Evaluative, Partial, and Spot. The first is the default. The second mode is mainly required for shooting against the light to make the foreground brighter. Otherwise, the picture on the background of the window will remotely resemble the silhouette genre. The third option is used in tricky lighting conditions, when the frame is flashing (overexposure) and deep shadows, and to calculate the exposure is enough for any one object.

Additionally, you can set the constant exposure compensation: simply slide the slider to get the desired result. All changes are displayed on the screen at once. If you want to make a series of frames with precisely defined exposure, it will block the re-determination by pressing the AE-L.

In addition to the usual

shooting information on the sidebar there is a shortcut key to a rare and fine tuning. Encoding settings not only allow you to set the compression of JPEG, but also choose to save the PNG format without loss. Among the facilities the Picture note sharpness. It is reduced to 2-3 or disable altogether, as add field during postprocessing can be neater and more difficult to eliminate the excess.

After setting the viewfinder can be set to display the histogram and its type, to establish an always-on mode screen, select one of the nine grids crop, or remove it altogether.

In the “General Settings” interest is the option to “focus before shooting.” Additional correction AF after pressing the shutter release significantly increases the quality by eliminating lubrication caused by shaking your smartphone. This is especially true for models without a hardware shutter button, which is necessary to press on the screen.

You can also change the volume of the error alarm, auto focus and a successful focus, adjust the shutter sound imitation and completely turn off all sounds. The latter is especially useful if you do not want to attract attention.

In some models of smartphones camera sound off transfer device to silent mode. In others, it always work force, and to remove it you have to gain root and deleting the corresponding sound file.

camera driver in the operating system Android limits the maximum shutter speed at 1/2 seconds. So fans of nocturnal species technically can not shoot in this genre regular means. Authors Camera FV-5 came up with his solution to the problem.

When you press the [P] -> [S] brings up a menu where you can set the shutter speed slower and arbitrary values. This mode is implemented by intercepting the signal and the Live View also has its limitations. Because the image was originally intended only for quick framing, it has a lower resolution and uses only part of the elements of the matrix. Depending on the manufacturer of the chamber and installed OS, it can be 0.3, 1.3 or 2.1 megapixels. Available options are also displayed in the settings.

When

Fujifilm introduced the matrix EXR CMOS, many objected to the new regime of low-light shooting. In the terminology of it is called SN (high sensitivity) and Pixel Fusion. Sense of the idea is to eliminate blur and improve image quality, sacrificing his (usually redundant) resolution. Adjacent pixels that register the same color, programmatically grouped together. For example, if two pixels treated as one, the shutter speed can be cut in half for the same value of ISO, but instead will turn 16 megapixel 8 megapixel.

tried to create a similar algorithm for built-in cameras and smartphones, but not very good at it. The fact that BSI CMOS has significant architectural differences from EXR CMOS, and without hardware support, so cunningly collect light from adjacent pixels useless.

Still something remotely similar we are seeing in Camera FV-5 when you enter a positive exposure compensation at the maximum ISO. Luminance noise turns predictably a lot, but often it is generally the only way to make a picture in semi-darkness. Full-time program can not cope in a more favorable environment. In those rare situations where there is enough light, you can manually set the minimum value of ISO (100) and get a clean shot.

smartphone camera often fails to detect exposure. Correct this deficiency will help auto bracketing exposure to your settings (“fork” from 3 – 7 frames). When photographing people simply choose the one most successfully arranged. If you’re shooting a landscape or architecture, then these images can then take a picture with an extended range of brightness (HDR).

Professional photographers often shoot a series of shots to watch an interesting face or a good perspective of the model. For a smartphone continuous shooting is not the most effective choice, but children playing or posing a group, it makes sense to shoot that way.

If you could still fix your smartphone, try to shoot the timer mode or time-lapse photography (timelapse). The first option is useful for self-portraits, group shots, or just more precise shots, because it eliminates the shaking during the descent.

lapse photography allows you to effectively capture the slow processes. Traditionally, it is used to capture the drop-down colors of the sky, atmospheric phenomena and demonstrate the changing time of day – see the example below.

Perhaps a separate application Time Lapse Creator someone seems more comfortable. However Camera FV-5 attracts exactly versatility. All functions are implemented in it as carefully as possible, and not to the detriment of others. Big Ball of Mud lies in the limitations of the free version. Maximum image resolution is 640 × 480, but the program is otherwise fully functional.


Camera MX


This program stands out among the more simple applications to capture smartphone. It attracts the ability to store geo-metadata in the image (EXIF). With their help, you can always easy to determine when and where each picture was taken.

menu program is much simpler, but it is targeted to other tasks. Instead of manually control all the parameters capture the emphasis is on the visual effects. There is a button at the bottom right entrance of the gallery images. By default, opens the last frame, the settings of which there can also change the icon on the brush.

If you’re not watching and post-processing, and want to get an interesting result at once, look for a library of special effects. They apply even before you click the “descent”. There is a box, overlays and stylized lomo camera. Some of them are available only in the paid version of the program.

Among the most useful effect can be called a pencil sketch. Such images are ideal for technical purposes and replace sketches.

As with most other alternative programs for photography, the function of the shutter button can be assigned to the volume keys. Scaling is a characteristic stretching motion with two fingers on the screen. However, much point in it, because the cameras are not capable smartphones change the focal length (single prototypes do not count). Zooming is as simple as framing, which can be done, and after the shooting.
