Does anyone know an easy method to ‘fake’ HDR with an LDR image?
I had an idea that I could do it by adjusting the levels of the image to create a series of images just like the ones you would get with different shutter times. However, this is quite an elaborate way…
I found a few tutorials that describes a way to do this with ‘scale maps’. That way, you use a normal LDR base-image, on top of which you add other images that mark the bright parts. Is blender capable of doing this? Can I composite an HDR image out of LDR images within blender?
examples of scalemap tutorials:
I guess I would either need to somehow scale the energy of every ‘LDR layer’ (so you have several layers of light, going from low to high energy), or let blender do the math.
