There are four parameters for Advanced Tone Mapping script: Gaussian blur, Opacity of blurred layer, Opacity of Merged layer, Copies of merged layer:
Opinions and suggestions for improvement are welcome!
- Gauss. Blur (% of img size) — is the amount saying how much the blurring should be used for the tone mapping. It is in percents of image size (where image size = (width+height)/2). Ten is a good default, but different values might be interesting too.
- Opacity of blurred layer — this is the 75 default, which can be changed if you want stronger or weaker effect.
- Opacity of merged layer — the default is 90. If 100 is not enough, consider increasing number of “copies of merged layer”.
- Copies of merged layer — when one, it’s barely noticeable, you can deny any accusations of postprocessing easily. Three has a lot of “halo effect” and anything above five will completely mess all colours up.
