BracketMerge is a digital image enhancement application used to merge exposure and/or focus bracketed images. BracketMerge enhances brightness color saturation depth of field and makes maximum use of available dynamic range (HDR). BracketMerge operates as an Image based Enhancement tool. The information in multiple exposure and/or focus bracketed images is combined or blended to produce a result image that has improved brightness color saturation and depth of field. The term Image based Enhancement is used to imply that image enhancements are controlled by and even limited by the pixel information contained in the various input images. This Image based Enhancement process produces result images with realistic brightness color and focus characteristics.
