If an image is too cyan, what color adjustment should be made in Photoshop to correct it? → Add blue
If you're working with an automatic camera and you set the shutter speed and the camera sets the aperture, what mode are you working in? → To create a 1-stop difference, multiply the original distance by 1.4. Example - if you were originally 5 feet away, a 1-stop difference would have you step back to 7 feet.
