A dreamy young pine blending in.
Here's how I create this effect from photography.
First I take 3 exposures of my subject, good, over and under exposed. It means lugging my lightweight tripod around with me.
I then use software called enfuse to combine the 3 exposures for the best well exposed photo.
A very high quality photograph.
Having the high quality image, I can then apply the anisotropic smoothing filters. The resulting clean, pure colour is very attractive.
After all there are no straight lines in nature.
