Here Comes the SunPart 2: Faking it
First lets deal with the corona and flare issue we had at the end of the last exercise. Because of the way the image sequence was compressed, pulling a decent composite was going to be quite difficult.
The simple solution is to use a circular mask.
If you havent done so already, create a Pre-Comp from all of the Sun images you downloaded from SOHO. This will allows us to treat the Sun sequence as a single layer.
From the Tools Palette select the Oval Mask Tool and in the Comp Window draw out a mask that encompasses the Sun disk, but excludes the flares, mass ejections, and corona. HINT: You can create a perfect circle by holding down the Shift key as you click and drag the mask.
You may need to do some fine-tuning to your mask as the sun is not a perfect sphere but rather slightly squashed. The end result should look something like the following.
|After using the Oval Mask, the unwanted portions of the Sun are no longer a problem.|
Not too dramatic now, but well be able to correct that in the next installment. For now, lets look at a way to create our own rotating Sun using the Production Bundle of After Effects. This will be a somewhat stylized Sun that is slightly darker than the image sequence.
