Learn Adobe Photoshop - Image Mode: Multichannel

Bestselling Learn Guitar on Android! In this video, Mahalo expert Gene Shaw explains how to work in Multichannel mode. Multichannel?Image Mode --------------------------------------------------------------------- Multichannel image mode operates without the standard color information present in previous color modes. This mode allows you tremendous freedom to save masks, color channels and other information. How to Work in Multichannel Mode --------------------------------------------------------------------- 1. Open up the Channels panel at the bottom right side of your workspace. You'll see the RGB channel (which is the one you're most likely working in) and three other channels below it: red, green and blue.?2. If you select one of those channels, let's say red, Photoshop will show you just a grayscale image. Essentially, this is how Photoshop views the image: it views several grayscale images which it then applies color to. If you view any two of these channels together, you'll see the result of just those two channels combined.?3. If you switch to CMYK mode, you'll see something very similar in the channels panel. The only difference is that the channels are divided into cyan, magenta, yellow and black instead. The concept is similar, though.4. Press Ctrl+K (Command+K for Mac) to call up the Preferences menu. Click Interface on the left, then check?Show Channels in Color. You'll then see the grayscale images in the channels panel now show as the colors they represent, respectively.?5. Convert back over the RGB, then switch over to Multichannel mode. By default, it does not assign a specific color to each channel. Instead, it simply puts the information in each channel and lets you decide how you would like it to show up. You may see your channels show up as CMY (no black), because Photoshop assumes you're working in print.?6. Press Ctrl+K (Command+K for Mac), click Interface on the left. Uncheck Show Channels in Color and click OK. You'll see now that your channels are back to showing grayscale images next to them.7. You can create a black channel by combining two of the channels. To do this, choose one of the channels, like cyan. Then click Image -- Calculations in the top menu bar. A dialog box pops up. Under Blending, choose Linear Dodge or Add and set it to 20% opacity. Choose Result -- New Channel, then click OK.?8. Now you have a new channel created. With that new channel selected, switch over to your layers tab. In the top menu bar click Image -- Adjustments -- Levels. Lighten the midtowns by dragging the arrow on the right to the left. Lift up the black a bit by dragging the left arrow to the right just a bit. Click OK.9. Double-click your new channel and a box pops up. Click the colored box, change the Y field to 0 (make sure C and M are also 0) and change the K field to 100.Go back up to Image -- Mode -- CMYK and you'll switch back to CMYK but with the added bonus of having your newly-created channel amongst the rest.Multichannel mode is neat because it doesn't store any of the color information, and you can change the way color is handled inside this mode.
