How to Get Rid of Color Noise in Photoshop
- 1). Open Photoshop and click "File," then click "Open." Browse to a photo on your computer to edit for color noise, then double-click it so it appear in your workspace.
- 2). Click the "Lasso" tool on the "Tools" palette on the left side of the screen. Draw an outline around an object in the picture giving off color noise, such as a t-shirt, balloon, flower or road sign. A dotted blinking line will appear.
- 3). Click "Image," then click "Adjust" and select "Hue/Saturation." Move the "Hue" slider bar to the left or the right, which completely changes the color of the item without reducing or increasing its brightness or depth of color. Click the "OK" or "Cancel" button.
- 4). Use the "Lasso" again to circle another area of color noise, one that is too bright or deeply colored for the picture. Bring up the "Hue/Saturation" menu again, but this time, move the "Saturation" bar to the left. As you do, color is gradually removed from the image, starting with the highest amounts. The farther left you go, the more grayscale the image appears. Click the "OK" or "Cancel" button.
- 5). Deselect any selected areas or blinking dotted lines by right-clicking and choosing "Deselect." Click "Image" and then choose "Mode." Choose "Grayscale" and click "OK" to the warning window. This removes all color from your image, including the noise; you can now pick and choose color to add back in.
- 6). Use the "Lasso" tool to select an area, such as someone's eye, hat or a river. Click "Image," "Mode" and choose "CMYK Color." Nothing will happen yet. With the area still blinking, click "Image," Adjust" and "Hue/Saturation." Move the "Hue" slider bar and you can add in color to your desire.
