![]() In the screen shot above, I dragged the slider all the way to the left and you can see in the Channels palette that this has darkened the whole channel to black – look at the image icon in the blue channel. The Constant slider affects the darkness or brightness of the selected output channel and while you may see some benefit from making minor changes here, take care with making larger changes to this slider. ![]() You will see a little warning triangle displayed in this case to highlight the imbalance. A total below 100% will result in a darker image, while higher lightens the image. ![]() This means that the overall tonal balance of the image remains the same. You’ll notice that the Total remains at +100% as the sum of the three sliders still adds up to 100. This resulted in the sky becoming a less intense blue while neither red or green added a dominant tint as they remained evenly balanced. In the screen shot above, I selected the blue output channel and reduced the blue slider to 50% and increased the other two to 25%. The first thing to do is to decide which output channel you want to work on out of red, green and blue and you can select this using the Output Channel drop down menu.īy default, each output channel consists of 100% of its own color and 0% of the other two colors. How Do You Work With the Channel Mixer?Īs I’ve said, working with the channel mixer isn’t too difficult and while its greatest use has always probably been for converting to black and white, it does offer an easy way to make creative color adjustments to your images. While using the Channel Mixer remains a viable way to convert photos to mono, it has been rather superseded by the Black and White tool that offers greater flexibility for conversions, plus a wider range of preset options too. These presets are designed to mimic the effect of using colored filters with black and white film. If you click on this, you’ll see a selection of options for converting your image to black and white. Once the Channel Mixer palette is open, the first thing that you’ll notice at the top is the drop down menu that will initially be set to Default. Otherwise, you can go to Layer > New Adjustment Layer > Channel Mixer. If the Adjustments palette is open, then you just need to click the icon at the right hand side of the middle row of icons, represented by three overlapping circles. This tool is pretty straightforward and easy to understand and in this article I’ll run through the various options that are available when using the Channel Mixer. The Channel Mixer adjustment layer in Photoshop can be used to apply creative color effects to your images, convert them to black and white, and add color tints to mono images.
