Choosing the right color gamut for your images in Digital PhotographyWhat is a color gamut? A gamut is correctly categorized as the span of colors that a device can create, such as a printer or monitor. People use different terminology-color gamut, device gamut, or simply gamut-but they all mean the same thing. The gamut is basically a way of representing the span of colors a printer can print or the scope of colors a monitor can display. There are many colors gamut's on the marketplace today, like Adobe RGB, sRGB, LAB, Pro-Photo RGB etc. Even though Pro-Photo and LAB are one of the best color gamut's available and have the vast color range (color range for Pro-Photo is 281 trillion colors!) making it the better choice for images. Most of our inkjet printers and laser printers are pretty much ineffective for this kind of color scope. In fact, almost 99% of the color printers nowadays are based on sRGB. Thus, most of the pictures out there are in sRGB. Well there are some downsides also with using sRGB. As such, it has a very small color spans though it is still larger than CMYK. The problem with sRGB lies in the fact that it does not represent the entire scope of visible spectrum, which means that the color of your image and print output may vary a lot from the original color. Such a small color spectrum clarifies that you would get saturated colors more often than not. Also during some editing work, there is every possibility that you may eliminate the colors that are even close. There are several reasons why the color range must be very large. The first one is so that it has a higher color appeal. In addition, it will print a much better image on a printer that supports more colors than the regular sRGB based printers. Adobe RGB is way larger span than sRGB. It has the same number of colors, because the image is around 8-bits. But these colors are spread over a much larger area, so the colors bright fringes, which are symbolic in RGB Adobe format, yet the sRGB differs. Thus, this brings Pro Adobe to dwarf the RGB. Pro-Photo is a 16-bit RGB space, thus it has trillion of colors. But can a printer actually print all of these? The answer is no, simply because the human eye is unable to as well, yet the point is missed here. The point is that PRO-Photo will be able to symbolize the orders of scale more colors than the sRGB, therefore even if you convert to sRGB in the end you're more likely to have an accurate conversion without losing colors. What more can you ask for, since society is moving at the speeds of lightning why not check out gamut's to see if it works for you. Photographers often have less time to spend on minor details, thus speed is always a need in digital photography. If you want to learn more about gamut and how it works, you best bet is to research the market. This may be a high technology resolution for some people, however for others it might not be an option to consider. Remember, if you are searching to learn what to buy for your new photography career, reading all the information and staying informed is ideal to help you along the way. Many photographers have posted sites that may provide information, however many I've noticed only offer photo galleries. Still some content-based informative sites do exist. by Readabout's Digital Photography Training Team |
