[QUOTE="480sparky, post: 587702, member: 15805"] Bracketing does not change the dynamic range of the scene. It is merely a set of images taken both to intentionally over- and under-expose the scene. Bracketing [I]with the intention of combining the resultant over- and under-exposed images into an 'HDR' [/I]image is [B]compressing[/B] the dynamic range of the original scene. I would use a GND only if a large portion of one section of the image was bright enough, compared to the shadows, such that it exceeds the dynamic range of my sensor if the exposure is set to record details in the shadows. Different cameras have different ranges, and it also depends on the ISO you're using. I would then adjust a GND to cut down on the brightest portion of the scene so it would be exposed within the range of my sensor. If the highlights and shadows were interspersed throughout the scene, I would bracket and create an HDR. But I haven't done that in about 3 years now. [/QUOTE]
