Hello folks,
Im looking for advice regarding my upcoming music video shoot.
Camera: HVX200
my concern: We are going to shoot in a abandoned church, the oltar has been replaced by huge greenscreen with markings for matting and tracking purposes. The greenscreen will be replace in post by a picture of a tree and the director wants rays of sunlight to be coming from it inside to the church.. Isuggested rigging couple of Par 64's and bring the mist machine over, but now Im having second thoughts about it.....would the fog and rays of light create any problems to the post guy in implementing the image of the tree? Is it better to add such effect in post? Thanx for any advice.

hello,
If the green screen is behind the rays of light/fog i recommend you put the rays in in post. The rays will be keyed out. Lighting effects are getting better and better now days with animation. Speak to your animator, and he will also tell you the best ways to achieve this.

Should of course still keep your tracking points, and i recommend you to light the green evenly and keep it as clean as possible.

Hope that helps.

I saw the trailer for "300" in the theatre recently and I loved the lighting effects displayed. They did a really good job of creating the shafts of light that you would get with smoke.

I suggest you check it out.
