- [Voiceover] So many factors come into play…when deciding on what background to insert.…If the subject in the photo for background replacement…has been taken with strong flash,…and this is obvious by the flash shadows behind,…it's best not use a daylight background of sky.…The lighting on the subject will show signs…of strong, frontal, artificial lighting…and a situation-specific background must be chosen.…A plain backdrop or studio backdrop…or inside scene would suit.…The flash shadows can then be either kept…or recreated to complete the scene.…
Similarly, if the subject was originally taken…in strong sun outside, inserting a background…of a shaded scene or low-light scene will not work.…A suitable outside scene with strong sunlight…must be used with the sun at a similar point in the sky…and the shadows following in the same direction.…If we look at our image, ours is in soft, outside lighting,…and there are some shadows because…this is shot in the shade, we don't need to worry…about strong shadows, all we need to do…
In this course, master restorationist Neil Rhodes shows how to accomplish tasks like these using Photoshop. He covers the entire process: evaluating the photo, choosing an appropriate replacement background, using Photoshop's selection features to create a precise mask, and then inserting the new background and matching the grain of the original.
