You, probably, have heard acronym EXIF in connection with digital chambers. EXIF considers the additional information, such as speed of a shutter, the aperture and the decision which will be connected with a photo file. EXIF guarantees, that chambers can register such information while other software can read and use it. Here, how. EXIF designates the Replaceable Format of the File of the Image.
EXIF does not define completely a new format of a file – in other words, EXIF acquaintance JPG or QUARREL files does not replace. Instead EXIF defines a number of signs and semantics which can be added to existing formats, such as JPG and QUARREL to give more information on a photo. For example files JPG use applied segments of a marker to include information EXIF while QUARREL files use variants of a sign of QUARREL. More exact description EXIF would be expansion to current formats of a file of a photo which allows the documentation of the expanded information of a photo – so for example, file JPG can include information EXIF. So, what information is registered by expansion EXIF? It really depends on the chamber which you use. Some chambers do not use EXIF in general while the majority of chambers makes entry of key parametres of adjustment in which the photo was is taken, such as the aperture, speed of a shutter, value of the International Organization on Standardization, the decision and is more.
We will not be run through the possible information which can store EXIF as it is very long list, but we will be run through some from more important usually used:
Width of the image / height in pikselah: number pikselov in X and Axes Y.
Orientation: chamber position when the photo was it is taken. For example there was a chamber in position of a portrait or a landscape?
Timestamp: date and time when the photo was is taken
The equipment Does / Model: sequences which describe the equipment a photo, were are taken with. Can do to be for example "Olympus", and the model can be for example “E-330”.
The program podverganija: the program podverganija chambers was in the habit to take a photo such as automatic, the aperture priority, a shutter priority, the program of action and is more.
Speed of a shutter / value of the Aperture / the Central length: speed of a shutter, value of the aperture and the central parametres of adjustment of length for a photo.
Measurement of a way: the way of measurement used, taking a photo for example: the average of weight of the centre, a stain, the sample and is more.
The flash status: the flash status, taking a photo. Includes the information such as, whether flash has been started, special parametres of adjustment, such as red-eye prevention and is more.
There are many programs, which you allow, that to read EXIF have contacted a photo. Exifreader - one of them also is more many, including popular programs of processing of a photo, such as the Photographic supplies store. Some programs can automatically use also information EXIF to make some basic processing of the image. One general such processing is photo rotation. If the information of orientation of chamber EXIF is accessible then, the software can automatically rotate photos as it is required. EXIF - the big tool to learn how to take good photos. Considering photos near to their information EXIF you can see exact parametres of adjustment of the chamber, taking a photo.
It allows you to find out, why good photos look good and why bad photos look badly. You can study, what parametres of adjustment of the chamber as a shutter and the aperture were correct for one scenario and which were correct for another, and using this information is used by the best parametres of adjustment in your future photos. |
