Now your images will come out of the camera without the infrared red biased images and will look more like normal RGB.
Now you can do that after the fact if you shot using RAW mode files.
Play with your custom white balance to get rid of the excessive red bias.
Or you can do it with Photoshop and curves hitting the red curves hard probably with an S shaped curve. Straighten the last 1/4 of the curve so you don't blow out the highlights.
ha blending is another subject and various ways to do it. As a layer and lighten mode is one simple way. Control the amount using the opacity slider. Screen mode also works but will be more savage and needs to be toned down more with the opacity slider.
