What are the techniques used to maximize IR in photoshop?

Many photographers still edit their IR photos using photoshop..

Based on their experiences, most of the techniques they used are: (all of the techniques require at least 2 layers.. one for background)

1. to edit skin tone: color balance (masking first), change the opacity

2. to edit the background color: levels

3. "fix" the contrast: curves, hue saturation.. (many prefer curves because if you used hue saturation too much, the detail of the image would be washed out)

4. too lazy to edit: auto color

5. play around the model clothes/landscape elements color: channel mixer.. some prefer selective color

6. add the dimension: burn & dodge

7. use other unusual techniques you like.. because, if i may quote, "Photographs in infrared show quite unusual tonality, different than that to which we are used, and this may make them esthetically pleasing, at least in many cases. Which, of course, is a matter of taste."
