8C. Correcting Color Cast (pdf) (link to comment)
As always, if you do not get your photos right in the camera, you can fix it in Photoshop. This video shares how to correct color cast when the white balance is not correct.
You can find the color wheel tutorial in Course 1 mentioned in this video on this guide page.
You can find the "Finding Perfect Background" lesson in Course 2 mentioned in this tutorial here.
I am really excited about this lesson. Be sure to watch the entire video. You will learn a lot about your camera on the third technique.
Here are your images!
