Does anyone have experience with filters that have a similar color shifting effect as IR photography (I mean, as much as possible) - without using a modified camera? I know that there are filters that only let through light of a certain wavelength (550nm,630nm...) but it seems like I will still need to get rid of that internal IR filter first... I am trying to figure out the best way to do some special shots without carrying around a second IR-modified Alexa... Just curious if anyone came across some interesting color filters (or filter combinations) that might also do the job. Also appreciate other thoughts on that topic.
During a couple of recent broadcasts, notably "Peter Pan" on NBC, I've noticed some pretty vivid fluorescing from the teeth of the talent. It was most vivid on the actor who played Peter Pan and was even mentioned by a couple of the TV critics. I've also seen the whites of eyes doing it as well. Do we know what causes this to happen? Is it an effect that is being used incorrectly? Is it something to do with the latest generation of camera sensors? Is it lighting related? Is it a chemical thing—something in the teeth whiteners or tooth veneers that is causing this? Is it only with broadcast-style cameras? And, of course, Is there a way to avoid it? Thanks
