Thread Title: Cross Channels / Channel Swap

Mike Brouphy   Mike Brouphy
This tutorial text was written by Arnold Hubbard and was part of his comments for December.

I've taken the liberty of posting it here because the process is often asked about here and in other forums.

1 Open a Raw I/R photo (Do not change to mono )
2 Create an adjustment layer - CHANNELS
3 Slide RED channel from 100% to 0%
4 Slide BLUE channel from 0% to 100 %
5 Change RGB box from red to blue
6 Change RED channel back to 100%
7Change BLUE channel back to 0%
8 Create an adjustment layer - LEVELS
9 Adjust LEVELS then click on AUTO
10 Flatten LAYERS
12 NEUTRALIZE sometimes improves picture

There is no doubt that you can get a huge variety of results and I think this is all down to the weather conditions.
All my best results have been with photos taken in " Good summer`s day weather " - good sunshine, little white clouds well lit scene.
In poorer weather the blue can be much too dark and not easy to alter.

GOOD LUCK.   Posted: 02/09/2015 17:29:32

Thread Title: DxO Optics

Mike: Every month I am amazed by the work you do with DXO Optics. After this month's image I decided to try it myself. I just downloaded the trial version of DXO Optics 10, so I can play with it for a month. I like the trial arrangement before making a $200 commitment.   Posted: 11/24/2014 11:09:10
