For the most part, I think it depends on the quality of the original image.. for example, a nice stacked image @ f/20 will be able to put up with more wavelet processing than my tiny f/5 images
From what i've learnt, from playing around and from reading about settings that others use, I use linear mode, and either:
- Use a step mode of 2 and modify layers 1, 2 and 3 to about 10 or so, give or take +/- 5 depending on how it looks.
or
- Use a step mode of 0 and modify layers 3,4,5 and 6 - 3 is the highest, sometimes around 20-40, and the other layers decreasing so that layer 6 is the least changed.
I also usually reduce contrast and brightness a fraction, but it depends what settings you used in the capture. The LPI might be different than the ToUcam in that respect.
Also, before doing any changes to wavelets, I click RGB shift and "estimate".
Also don't forget to choose a proper processing area size and click in the middle of your object to centre the processing area, or click "do all" to do the entire image.
Good luck!
