In theory arguments are irrefutable. glamox lighting In practice things are little shade. Jpeg site has its supporters, especially among those who categorically reject any alteration of the image obtained in the device. I propose in this presentation to bring some light on this dispute.
RAW is associated with the highest level of quality and a large control over the images (brightness, color, etc.). Right, but the possibility is not totally excluded editing for JPEG files. glamox lighting
J oint P hotographic E xperts G roup (short Jpeg) is a file type for storing glamox lighting digital images glamox lighting quality loss ("lossy") by the use of compression formulas. It "mp3's" image to get a better understanding on it. As such, to a point, normally are not noticeable quality loss.
Also, each resalvare loss of quality, but very little. Below see 5 times in succession saving a JPEG file. I chose the original, 3rd and 5th rescue. Quality losses are small ordinary man. Furthermore, the file size is almost glamox lighting identical, but will continue to rise slightly glamox lighting as it gathers "ballast" (artifacts). glamox lighting At resalvare I used the option to keep the original file quality. I could do a contest now, who found differences.
Attention resalvarea not mean copy / move. A copy Jpeg retain quality original file. So we're talking about a myth. Copy / move does not mean losses. A Jpeg can be moved to infinity. After some opinions circulating on the Internet and beyond, this operation would involve the quality of the time.
Small size relative to the fairly high level of picture quality and almost universal support for this format on any platform software and hardware is a major advantage.
Above I put another example of reducing the file size with quality loss related. Quality 60% - 55.9 KB, as 80% - 93.8 KB-quality 100% - 493 KB. Notice how the 20% reduction in quality has resulted in a file about 5 times smaller and not 20% lower.
Unfortunately glamox lighting this requires a little more technical approach, which might not inquire too much. But I have no way to reach a correct conclusion regarding the "dispute" between JPEG and RAW.
RAW is a "container" that contains the "ingredients" in order to obtain an image. The ingredients are largely a sequence of numbers that are interpreted differently depending on the program you use to "extract" a RAW image file. One of the arguments in favor of RAW is just that programs have evolved over time, providing an increasing quality of image obtained.
RAW is equivalent to the negative of the film devices. It contains data directly from the sensor unit, image unenforced. This presents glamox lighting a great advantage for those who wish further processing. If you use the JPEG format, then the machine will decide what changes are implemented. If you use RAW format, glamox lighting the data can occur later, usually glamox lighting in a semi-automatic (ie no longer applies machine, but the computer program used, and you have the freedom to modify certain values).
RAW is a generic name. There is no standardization across all producers and sometimes they do change the format from one generation to another, the permanent need of an update program glamox lighting that supports these files. Also manufacturers glamox lighting to encrypt their RAW files can not be edited by any program, partially or totally.
A photographer who does not understand the light will make many mistakes, difficult to repair by further editing. The importance of light is often emphasized at a professional level in an indirect way, the outdoor scenes, glamox lighting where artificially controlled, glamox lighting sometimes even primitive.
Thomas Young (1801) Hermann von Helmholz with (in 1850), presented a theory that one sees color as a result of three types of photoreceptors existing on the retina that respond to red, green and blue ("Young-Helmholtz glamox lighting trichromatic theory glamox lighting "- without actually prove their existence). Truly some pioneers since 1956 Gunnar Svaetichin only showed these receptors.
What's going on? If an object absorbs all the "colors", less orange, the object will be orange. But if you see the whole spectrum, except blue, all orange object will appear. Colors "blue" and "orange" are complementary.
The colors are a creation of our brain. Appliances
