We've color graded quite a bit of the scene now, so that the various…buildings match the sky.…One major area of the original footage we need to do a still though is the trees,…so let's look at that area.…I'll start by copying the effects from BuildingPatch upwards to Trees, so the…Curves, the Color Balance, and the Hue/ Saturation, Shift select those, Ctrl+C or…Command+C and then paste onto Trees.…Overall this matches better now, but we can continue to adjust these effects to…try to get better edges on the leaves and that's a real difficult area.…
Now the effects I pasted come in at the bottom and that's fine, we still…had the original Curves and Color Range we used to remove the sky, the new…Curve becomes Curves 2.…I will start by trying to adjust the Curves to see if I can improve the edge quality.…For example, I can go to the top Curves to maybe darken the very end of the curve…and there will be a slight difference in the resulting color range keying.…I can also adjust the Curves 2 that I just pasted in, to make a bowed down…
Learn how to track the footage with the Adobe After Effects 3D Camera Tracker, replace areas such as the sky, rotoscope moving elements such as buildings and cars, and integrate a digital matte painting so it gains appropriate shifts in perspective and scale. You'll also apply color-grading techniques and learn how to fabricate reflections. The course also covers an alternative motion-tracking workflow with the Foundry CameraTracker plugin.
