Pre-Monsoon clouds were gathering as I shot this photo at Seethanadi Nature Camp inside Someshwara Wild Life Sanctuary, Hebri Karkala. I used Canon EOS 5D mark II with Canon EF 16-35mm f/2.8 L USM Lens on a tripod to get 3 bracketed images at 2 stop difference. I used Photomatix Pro to fuse exposure of these three bracketed shots to produce this photo. In Expo­sure Fusion a series of brack­eted images are processed to produce a dynamic range image. It takes the best tonal­i­ties from each image in the sequence and com­bines them to cre­ate a sin­gle image. Best part of each image gets recorded and fused together to com­bine all of the best ele­ments in final image. You have quite a lot of control to adjust which tonality of the exposures are used in the final image.

You might ask how is Expo­sure fusion is different from HDR? The only resem­blance the two have are that they com­bine a sequence of brack­eted images together. In Expo­sure Fusion the final prod­uct looks more real­is­tic to how the scene really would like. This means that the shad­ows main­tain a cer­tain amount of shad­ows and the high­lights remain brighter in higher tonal­i­ties then a high con­trast scene.

HDR takes the sequence of images and blends the images seam­lessly but does its best to even the tonal­i­ties in the extreme tonal­i­ties of shad­ows and high­lights. That is why HDR the appear­s arti­fi­cial­ and unnat­u­ral­.

Expo­sure Fusion after fus­ing the images together keeps the tonal­i­ties how they would appear if one was to be look­ing at the actual scene being pho­tographed. HDR image most of the time shows the uneven tran­si­tion between the lumi­nance and can there­fore lose the appeal of real­ism. Expo­sure Fusion pro­duces results that are truer to the scene that the pho­tog­ra­pher is try­ing to capture.

Photomatix Pro produces both fantastic HDR as well as Exposure Fusion. Try it and you will love the results. Trial mode is also available for Photomatix Pro.
