Pro Tip: You can use the Color Mixer for cross processing, which is how filters are created for apps like Instagram. By crossing several different color channels, you can get unique effects that create specific moods or aesthetics.
Step 2: Go to the Edit menu then choose Color Mixer under the Miscellaneous section.
Step 3: Move the color adjustment sliders to see how they adjust the color profile of the image you're working on.
Step 4: Click the Black & White card icon under the Adjust panel to turn your image into a greyscale. Then use the same color adjustment sliders to change the value of the black and white areas.
Step 5: If you only want to add the effect to certain parts of the image, click on the Erase tab and use the paintbrush tool to select where you want it adjusted.
Step 6: Click Apply to save your changes. Continue adding to and editing your creation. If you're
done, be sure to save your project!
