YoHDR is still in beta, but from what it looks like seems to promise very well. Born from the creators of VectorMagic (online software that allows the vectorization image grid) the site allows, after’upload some photos the same landscape with different exposures, to download the photo HDR.

In practice, the HDR is nothing but an average exposure photos.

It may seem clear to everyone that the HDR does nothing but keep the cleanest possible contours. The left part of the image in this case is much brighter of the right side. YoHDR (like all software HDR) does nothing keep the parts of the picture with the right exposure, eliminating those overexposed or underexposed. And the result is there for all to see.
