Özgün görüntü

Filter applied with default settings, after changing image precision in GIMP to 32-bit floating point linear light.

This filter can be used to adapt an image, which may have a high dynamic range (HDR), for presentation using a low dynamic range. This operation reduces the magnitudes of local image gradients, producing luminance within the range 0.0-1.0.

This tonemapping approach was originally presented by Raanan Fattal, in the 2002 SIGGRAPH paper: Gradient Domain High Dynamic Range Compression.

	Not
	This filter is slow on larger images. For finding the best settings for your image you could make a small relevant selection first and save that as a preset before using that for the whole image.
