Colors in a photographic image are usually based on the three primary colors: red, green, and blue (RGB = Red, Green, Blue).This is called additive color system because when the three colors are combined or added in equal amounts they form white. The intersections of the three colors are cyan, magenta and yellow. The RGB system is used whenever light is projected to form colors as in color monitor (or your eye). When you combine red and green you will form yellow, red and blue when it is formed when the magenta and blue and green form cyan! If none is combined or off will be a black pixel.
The digital cameras color values range from 0 to 255 degrees of intensity for each color reaching 24 bit color, or two to the twenty-four, a combination that provides real 16,777,216 colors.
Photo editing programs
Once we have our photos stored on our digital camera, scanner, came down from the Internet or e-mail we receive, we must accommodate our needs, such as cropping, adjusting brightness, contrast, color, make collages, add text, effects lens, distortion, filters, and plenty of possibilities that could be accomplished with photos taken with traditional film. All these tasks are photo editing via software.
All digital cameras bring some basic photo editing program but it is recommended to use professional programs that have a myriad of possibilities and today are simple to use, expensive and there are also free. We recommend using the “Adobe Photoshop” or “Paint Shop Pro” as the best in the market but the list can be long and growing every year with new programs.
To browse hundreds of photos in albums simultaneously as well as to see them one by one, to entire window or full screen images show time, we recommend using the best program for viewing or browsing images.
How to choose a digital camera
When you start to investigate, observe that many digital cameras have similar features, but that does not mean that all offer the same performance. Read the reviews (both online and in magazines). Some of the key considerations are: the resolution and the number of megapixels, optical zoom, the type and amount of memory, type of batteries, the type of Monitor built to allow the ISO to get good resolution photos in motion, whether for print or just look on the screen.car image editing service
