Ho to blur the image, with as much less effort as possible, so the blur wraps around the edges
I want to blur HDRI maps
- Duplicate your original image into a new layer.
- Add guides to edges of original image.
- Enlarge your canvas by 200%.
- Duplicate the image to all eight neighboring sides to make seamless tiling.
- Apply blur of choice.
- Crop your canvas down to original size.
- You now have wrapping blur with no hard edges!
