How to Fix Photos With a Channel Mixer

A channel mixer is a tool found only in photography editing software. It is an application that allows you to virtually separate the three or four channels of a photo, and change them on a percentage scale. The use of channels changes the saturation of color depending on the channel mode. The channel mixer is primarily used for converting photos to black and white, as it allows the operator to maintain or enhance absent levels of contrast and detail. It also enhances color outputs in colored photographs the same way a colored lens filter would when attached to the lens of a camera.

Instructions

Understand RGB and CMYK. At any time you can alter the mode at which your photo software processes your image. These modes include grayscale (black and white) and the color modes RGB and CMYK. RGB stands for red, green and blue, while CMYK stands for cyan, magenta, yellow and black. You can change the mode in Photoshop by clicking the "Image" bar on the top drop-down menu, and selecting "Mode." The differences between RGB and CMYK when using a channel mixer are the colors that are being manipulated. RGB is more commonly used than CMYK when adjusting color components of a photograph.

In Photoshop, there are many ways in which to convert an image to black and white, and they will all produce variant results. To use the channel mixer to turn an image to black and white, first access the channel mixer screen. In the drop-down tool bar select "Image" followed by "Adjustments" followed by "Channel Mixer." A small tool pallet will appear on your screen. Before adjusting the RGB (note: you cannot use CMYK color mode to alter a photo to black and white using the channel mixer) levels, check-mark the small box at the bottom of the pallet labeled "Monochrome." This will turn the photo black and white, after which you can adjust individually the reds, greens or blues to increase or decrease the white and black contrast through the original colors (though you will only see black and white). There is no set percentage to adjust your image to, as it completely depends on the quality and original contrast of your photo. Nothing will happen to your photo until you press "OK," so take some time to experiment decreasing and increasing each percentage until the photo looks how you wish it to look.

Adjusting colors. Channel mixing for color adjustment works the same way as channel mixing for colors (without going to black-and-white mode). The only difference is that you will not select the "Monochrome" feature at the bottom of the pallet. The channel mixing in color mode is less common than in monochromatic, as very slight increases in percentage are needed. Channel mixing in color mode tends to alter the realistic color balance of a photo. However, if the effect you are attempting requires the complete alteration into unnatural colors, then adjust to any degree you prefer. This can be done in either RGB or CMYK mode.

Making corrections. "Would you like to understand digital photography systems that bring professional photographers to where they are today? Well, The Top Secret Photography Techniques would likely assist you out in doing so. To get stunning pictures we primary want to look at some essential photography strategies. The initial one I am able to share with you is discover about light. You can locate every little thing concerning photography techniques on , The Top Secret Photography Techniques. Each time you uncover about light and in what method it interacts with the direct environment then your photographs will get superior..". Along with properly controlled desaturation (turning a photo black and white) and color alteration, channel mixing can accomplish specific corrections on a photo. If you are dealing with a portrait in which the model has less than perfect skin, altering the red channel will lessen if not completely diminish the appearance of skin imperfections. The blue channel will usually sharpen facial features and highlight characteristics.
