Photography

Photo(Frenchphotographiefromothers-Greek.Φως / φωτος - light andγραφω -writing, light painting-technique of drawingwith light)- obtaining andmaintaininga still imagewitha photosensitivematerial, orimage sensorin the camera.

In a broadersense, thepicture -it isthe art of gettingpictureswhere the maincreative processis to search forand selection ofthe composition, lighting and moment (ormoments) ofthe photograph.Such a choice isdetermined by the abilityandskill ofthe photographer,as well as hispersonal preferencesand taste,which is typicalfor any kindof art.Photo- thatcreativityand craft, an art, a profession and ahobby,and sometimes it isthe purpose andmeaning of life.

Eitherthe camerais:
lens- optical systemthat formsan optical imageon a photosensitive material;
shutter,determiningthe time duringwhich the lightfalls on thelight-sensitive material(the rolecan performthe lens cap);
the camera body protects thelight-sensitive materialofstray lightexposureduring shooting, with the objectivelens mountboardorbodycan be used forfocusing;
cassette witha photosensitivematerial (it is adisposable camerabody) orthe CCDwithits attendantequipment;

All other elements ofthe cameradoes nothave a directinfluence on the processof shooting andmaybe presentin the structure,andabsent.

Shooting(cъемочные)
Light meterandfleshmetr(экспонометрифлешметр)-a device for determiningthe lightshooting conditions.
Lighting equipment.For shooting inlow light conditions, various lightsand reflectors.Most numerousamong them werethe flash, but in a studioandmoviefilmingwill continue to applythe traditionallighting systems.
Studio lighting.Withstudio photographyusing specialflash,which are muchmore powerful thanbeing connected tothe hotshoe.Thereare two types ofstudio lighting: pulsed and continuousillumination.
Tripods(штатив)are used toprevent the "smear" in a dark, Stitch, at slowtoinstall additionallighting equipmentfor the multipleshootingone frame, etc.
Optical filters(светофильтр)are usedto compensate forthe color(conversion) and spatial (gradient) lack of coverage, to obtain specialeffects.

The expression "object in focus" means that a particular point on the object is clearly captured by the camera. In fact, the focus is also the area directly in front of the focal point, and for her. This area of focus, or sharpness, is called depth of field.
One of the main purposes of photography is the focus on the subject. In addition to photo look professional, you must also take into account the area of ​​the image directly in front of the point of focus and her (DOF). If the area in front of the point of focus, and her small, the depth of field is small.If this area is large, and the depth of field is large. The degree of depth of field controls the size of the active aperture.

Bitmap graphics editor (растровыйграфредактор)- a specializedprogram designed tocreate and manipulatebitmaps.Thesesoftware productsare widely usedin theillustratorswhen preparingimages for printinghard copyoron photo paper,publishedon the Internet.
Rastergraphics editor allowsthe user to drawand edit imageson a computer screen, and save them in variousrasterformats, suchas, for example, JPEG andTIFF,allowing you to storebitmap datawith littledecrease in the qualityby usinga lossy compression algorithm, PNG andGIFsupportinggoodlossless compression,andBMP,and supports compression(RLE),but in general,which is auncompressed"per-pixel" image description.

Format JPEG (Joint Photographic Experts Group)
One of the most popular formats. It allows you to compress images to save disk space, but there is a loss of data and the quality of the original image. JPEG (jpg) to view images 8x8 blocks of pixels, and analyzes and averages information. (This, of course, a primitive statement.Compression complex and multi-stage.)
The compression ratio and, consequently, loss of quality, regulated when saving a file.
When working with images in JPEG format to remember that every time you save a file as a "File> Save As" is a repeated compression and additional loss of quality.
JPEG format is not suitable for saving images with precise color borders and vector graphics.
Format TIFF (Tagged Image File Format)
TIFF format to store color images with color depths up to 24 bits and mono, color models in RGB, CMYK. When saving images in TIFF format processed data from the image sensor is recorded in uncompressed form, which gives a great advantage in the post-processing compared to JPEG. It should be noted that, in connection with the above, the size of TIFF-file much larger JPEG.
RAW
RAW is often called "digital negative". RAW-files contain unprocessed data recorded directly from the camera's sensor. Therefore, they have more information than any other format. Which gives us an informative stock?
First, the exposure compensation. Can significantly improve images taken with a 2-3 stops overexposed and underexposed in 0.5 steps, ie may recover detail, respectively, in the shadows and highlights.
Secondly, white balance correction. If you make a mistake when shooting and correctly set the white balance, it does not mean that the frame is lost. When processing RAW-file this error is easy to fix. The fact is that if you set the white balance in the camera, it does not affect the actual shooting: white balance - an instruction of the camera, how to handle the data from the sensor. When shooting in RAW does not matter what white balance is set at the moment. It can be installed in the process of conversion RAW-file. In addition, many programs allow converters to determine the white balance "on the model." We have to find a neutral gray object in the picture, click on it, and the program will recalculate the colors so that the object was indeed a neutral gray. Such a method of adjustment can be carried out with a different format, but all the same RAW-file is not an 8-and 10.12-bit data.
These are the main features and benefits of RAW-file.
