That's not to say SHG imagery can't be improved upon....and this is something I'm still exploring. It will be interesting to see what differing scanning speeds and stacking software can do....when the weather clears!

If you manage do derotate one stack then you could do a bicolor rendition. Like A AB[x%/y%] B. See what works best to increase contrast and highlight matching features. Bit of fun for a rainy day.
