Besides, unequal lighting can be avoided by practicing positioning as well as resorting to modifiers according to the size and distribution of lights. Instead of preparing unattractive background boards which would take up certain room, making the RGB LED lights emit on a white background can easily satisfy the need for multiple color backgrounds. Go and buy COLBOR RGB video light at Moman PhotoGears Store So, let’s talk about how RGB LED is used in portrait work when pursuing for the missing spark. Using RGB lighting creates more inspirations while finding the little spark that went missing when traditional methods have been used only. RGB LEDs can adjust the color saturation and hue cleverly right at the source to maintain proper color balance between LED lights, camera and existing or ambient light for natural looking results. It means red, blue and green LEDs combining in multiple collocation to produce different hues of light. Gradually, some people find it important during workplace that color adjustment to be faster and more accurate than this traditional method, as RGB LED can do.Īfter knowing what does RGB stand for, RGB LED should be easy to understand. It is a rather straightforward and fairly inexpensive method, but lacking the consistency of output and color accuracy. What is RGB LED?įor a long time, photographers have been applying gels and filters to lights source to add some colors while reserving high output of the light. If set at the lowest intensity, (0, 0, 0), at this time black is rendered. If the three colors are set at highest intensity, (255, 255, 255), then white is rendered. Simply combining the different intensities of these 3 colors to form multiple parameters (red, green, blue) to specify colors on the spectrum that human eyes can see. The intensity of the red, green and blue colors is described as an integral number among 0 to 255. RGB is specified with 3 primary colors - Red, Green and Blue. In this article, we would like to have it explained and show you one of its specific applications in photography which probably is a field each of us ordinary people is somehow familiar with. Move the servo to its minimum, mid and maximum positions.“ What does RGB stand for? What is RGB used for?” Such questions are now more frequently asked since RGB has been more and more widely used in illuminated devices such as lights and screens of electronic products. off () Servo Ī servo motor connected to a single pin, 3.3v and ground. play ( note ) sleep ( 0.1 ) # leave a gap between notes finally : # Turn speaker off if interrupted speaker.
