Matt Porwoll ultimate diffiusion bounce tests

[Joe Cage]

Hello,

Matt porwoll just released this.

http://mattporwoll.com/the-ultimate-diffusion-bounce-test/

I do have a question I see that the color temperatures by each setup is changed. Does that mean I need to change my whitebalance to each diffusion? Like for example I am shooting outdoors, white balance is 5500, I bring in some unbleached muslin as diffusion material as my keylight. Do I leave my WB to 5500 or do I change it to 4530°K? Because this would mean I def need to print out this list for ref on sets

Thanks!

This is a great compact handbook. Thanks for sharing this Joe.

That's up to you. I personally like the warming effect that unbleached muslin has. I wouldn't want to correct that out; that's what bleached muslin is for. That said, if you do use unbleached and WB to it, you'll push your ambient light in a blue direction -- could be useful for some applications.

This definitely. If you like what it does to light but don't like the warming effects, use bleached muslin then. I often warm up my key lights while maintaining a "normal" white balance (like 3200, 5600, etc) for standard setups to help the skin push out from the background. If the desired look is cooler I'll match my WB to my key-light and gel from there. Remember, numbers and math are awesome foundational elements....but shooting is about that knowledge to create the look you want...and in that it becomes more art that science.

What I did find interesting though, is that diffusing through bleached muslin had a warming effect but bouncing cooled it off. Never would have guessed that.

Joe,

Thanks for providing this link! from a brief glance over of the material in this article, I have found that there is a shitload I need to learn about lighting!
