A method to do something similar directly in PS without any third party filters or programs is to copy the foliage layer, apply gaussian blur, copy the blurred layer a few times then merge and put below your original layer.
Is there any way to have an image plane behind the geo in the perspective camera view? I tried adjusting the image plane's Depth, and I also tried adding layers: image plane as layer1, geo as layer2), then placed the image plane layer under the geo layer, but that didn't work either. Does anyone know of a solution? Thank…
