The HDR-APP takes three 360° pictures with different exposures (correctly lit, underexposed, overexposed). Afterwards all three pictures are automatically being merged to a perfectly lit high quality 360° HDR image.
Imbalanced illuminated rooms, e.g. with bright window areas and dim corners, can perfectly be presented that way.
It is also highly recommended to use the HDR-APP in bad lighting conditions in order to reduce the image noise.
