Shadow & Highlight is the final effect available in the Adjust group. It can be useful to correct exposure problems within an image or video clip. For instance, a clip may appear too bright in some areas, yet too dark, with too much contrast in others. Select the effect and apply it to the Fisherman 1 video clip or any other clip that you have on your Timeline.
Ensure that the “More Options” triangle has been twirled down to view all of the options available.
When the effect is applied, the Auto Amounts option is checked automatically and the Shadow & Highlight manual adjustment controls are greyed out so that they may not be altered. Switch the “Fx” button on and off to observe the effect upon your image. If your video clip has been captured with good lighting and exposure then the auto-corrected difference may be subtle. Let’s look at a before and after on our Fisherman 1 video clip. The image on the left is the original.
Look at the side of the green boat, the change is the most noticeable there. There is quite a good balance within the original image, so it has not been altered too much.
With the auto settings checked, Premiere CS6 will analyse the video on a frame by frame basis which will create an unnatural result if the lighting conditions change within the video clip. With Temporal Smoothing increased, Premiere analyses several frames at a time, to employ a more gradual change.
This works with Temporal Smoothing in that Premiere will detect a change of scene within the clip, and ignore those frames when making smoothing calculations.
Let’s try a different image, drag an instance of the Interviewee 1 video file to your Timeline. The original image looks like this:
Here is the affected image with the auto setting checked:
If your image contains quite a lot of shadows, the auto setting will tend to be a little harsh, so it may be better to un check this setting and make some manual adjustments. Uncheck the “Auto Amounts” box and let’s explore the options.
This defaults to a setting of 50. At zero our original image remains unaffected, at 50 the shadows are considerably lightened.
This setting defaults to zero in manual mode. Increasing this setting will seek out the highlights in the image and darken them.
