Hi IgorBeg, If I look at the videoscope, the two do not seem to be connected. Brightness shifts the whole waveform up or down, contrast changes the total size of the waveform. I have not recently tested it, but I think my TV acts the same. Brightness changes the black level, contrast does not. Contrast on the TV makes only the highs more or less brighter. |

Hi MatN, Brightness and Contrast are connected together. It is not possible to detach one each other. If you have a probe to calibrate your monitor you know what I say: when you change contrast parameter also brightness changes its value. To take another example with something you know (I think), in photography you have Aperture, Exposition Time, and ISO (sensibility). In the same condition,when You have take a shot if you want to increase of a “stop”, you can change Aperture, and the photocamera will change the Exposition Time value, or change Exposition Time, and the photocamera will change the Aperture value. Of course, if you change ISO value, the others two parameters, Aperture and Time, change. The light that enter in the camera’s sensor (film, in analog camera) is the same but the two parameters are different. In your case I would use Histogram Bezier plugin, more powerful than Brightness/contrast plugin. Usually Brightness/Contrast plugin is used for minor adjustment. I think so. |
