Let’s say in a film, there is a scene which simply takes your breath away. Maybe a storm brewing above, the atmosphere changing in the environment. pretty interesting right?
This blog shows the magic of a changing in the skies and the feeling in which it brings to the environment you are trying to imply as the developer of VFX artist. First let me show you this image…
Firstly, this composition may consist of a JPEG image and either a still, panning or any other footage for the effect to really take hold. To start off, the linear wipe tool needs to be used to add the feather effect on the horizon as most would see any other sunny day. Applying this will show immense realism and give the audience extra to look at rather than a blank canvas.
Next, the ‘Linear color key’ will keep the JPEG image from being show on anything but the ground and by doing this there will be more room for safety and less for risk of positioning images or effects.
Finally, adding colour balance to your composition should give the overall effect and footage a more natural feel and with the right adjustments; everything should look more natural.
