[[File:]]

8. Then move the playhead to the 9:15 second mark and bring the value for the Flare Brightness up to 150%.

[[File:]]

9. Move the playhead to the 10 second mark and make another Keyframe with the Flare Brightness at 0%.

[[File:]]

10. Press SPACE to preview the composition. The moon should be transiting across the sun with the lens flare growing in brightness then quickly disappearing once the moon is directly over the sun.

Exercise 5 : Add Second Lens Flare and Keyframes

[[File:]]

2. In the Effects & Presets Panel, search for “Lens Flare” and double click it to apply it to your adjustment layer.

[[File:]]

3. Under Effects > Lens Flare > Flare Center, change the the Flare Center position so that it is at the bottom left edge of the “Sun” layer. (See screenshot for reference)

[[File:]]

4. Move the playhead so it is at the 10 second mark and create a Keyframe for the Flare Center.

[[File:]]

5. Move the playhead to the 18 second mark and change the Flare Center Position so that it is towards the center of the “Sun” shape.

[[File:]]

6. Move the playhead to the 10 second mark and make a Keyframe for the Flare Brightness at 0%.

[[File:]]

7. Move the playhead slightly right to the 10:15 second mark and make another Keyframe with the Flare Brightness at 150%.

[[File:]]

8. Then move the playhead to the 18 second mark and bring the value for the Flare Brightness down to 0%

[[File:]]

9. Press SPACE to preview the composition. The moon should be transiting across the sun with the first lens flare growing in brightness then quickly disappearing once the moon is directly over the sun. As the Moon continues transiting across, the second lens flare grows then slowly disappears as the Moon leaves the frame. Some adjustments to the values keyframes may be needed if certain animation do not line up correctly.
