This is a piggy back off an earlier thread on filter use. I've used them (graduated ND filters) in the past but since switching to digital I find them somewhat slow and cumbersome and sometimes lack the flexibility I'm looking (see example photo which is a multiple exposure blend). So the related questions are: a. When you are in a situation where you see a huge dynamic range what do you find as "usual" bracket range. I've been usually just hitting the 3F (3 frames on the D300) with one stop under normal and one stop over. b. In your post process do you use HDR (I have very little experience in this area other than poking around at it in Photoshop) or do you do a simple manual blend using layers, masks and brush tools. Is there a situation where one method (HDR) is superior/faster or provides more control than the other (manual blending). c. Do you find any situations where graduated ND filter provides a distinct advantage over taking multiple exposures and post processing?
