    Hi Cafe!

    I am trying to get nice IR shots and also am trying to create multi-color conversions using the channel swap. How exactly do you get the WB right with a Hoya R72 filter? I usually shoot with WB set to "sunny." Thanks for your help!

  2. Find a nice green patch of grass on a sunny day, put the IR filter on, and set your WB off of that.

    Thanks Jimmy! I will try this out tomorrow and try to post some results. Does this work if I set the WB before placing the filter on?

    Do it with the filter on, I believe.

    No! To get the classic 'infrared look' you want greenery to be white. So set the white balance to think that green with the filter is white. It'll turn out to be below the temperature of tungsten. If you shoot Raw, you will be able to change it after the shoot.

    Thanks Daniel and Chris,

    It makes more sense to have the filter on, but you never know. :smile: Now all I have to do is find some grass here in the desert! :biggrin: Maybe I will try adjusting the WB on a palm tree. Thank you again for all your help, and I will be posting some images soon for some C&C from you pros!

    A green palm frond should work just fine.

    Chris is correct in the procedure for getting a classic IR look.

    But that's not to say that experimenting, or ahem, mistakes, can't be interesting too.

    This is an image where because I was in a hurry, I made my custom WB with the filter off. Before black and white conversion it was a pink nightmare, but afterwards I got an image that I like quite a bit.

    Long story short, don't be at all afraid at trying out different things.
