How to Delete Photoshop Channels

Quickly delete channels from images in Adobe Photoshop.

Adobe Photoshop is one of the world's most widely used graphic design applications. Included in the Adobe Creative Suite, the program allows designers and photographers to create and edit bitmap images in a range of formats, including JPEG, PNG, TIFF, and the Photoshop Document (PSD) format. Photoshop gives users control over many aspects of digital image files, including tools that allow for the deletion of individual color channels. Once you know where to look, removing one or more channels from an image in Photoshop becomes a very quick task.

Instructions

1. Open the image you want to edit in Adobe Photoshop.

2. Click "Window" in the top menu bar and locate the "Channels" item. If a check mark appears next to the item, do nothing. If no check mark appears, single-click "Channels" to enable the corresponding palette.

3. Select the Channels palette. It is located on the right-hand side of the screen by default.

4. Single-click a channel name (e.g., "Blue," "Green") to select it.

5. Click the icon resembling a trash can, found at the lower-right corner of the Channels palette, to delete the selected channel. Click "Yes" when prompted by Photoshop to confirm your choice.
