"Help required with WB setting . . . . or is it?"


NZ
          

Hi all,

I've been experimenting with my Nikon D3200 which I had converted with a 590nm filter at Kolarivision.

Setting custom WB, I'm finding, is impossible by the in camera measurement technique (I'm not even sure how necessary this is, if I can set WB in NX2).
I've plumped for Incandescent setting based upon what I read on another forum, but despite this, and my use of NX2, I cannot get my foliage looking as white as some images I've seen here and elsewhere.
My original image looks, to me, more contrasty and reddish when compared to some "starting points" I've seen elsewhere.
What I'd really love is for someone to take one of my images and work it, so that I/they could establish where I'm going wrong.

Any help/advice anyone can offer would be greatly appreciated.

The camera is more limited in its range than you can achieve in NX2, Capture One, Lightroom/ACR and other raw converters. For that reason, I set a fixed white balance in Lightroom/ACR as part of my infrared camera default rather than having it read the in-camera setting. It then opens up looking just about right. If I open it up in NX2, it's very red, but I can adjust the white balance.

BTW, I don't usually white balance foliage with a camera in that spectral range, but something like a cloud or other "neutral" or grey subject. I'll then use a black and white conversion process that uses a yellow or orange filter equivalent. With something like a 720nm or 830nm-converted camera, I'll white balance foliage. Those conversions typically aren't a problem to white balance in-camera.

I'd be happy to look at a raw file if you'd like.
