Is there any use for burst mode while shooting landscapes? Or is it done just because it can be done?
I’m with RG on this subject. When I’m taking pictures that are important to me and/or would be very difficult or impossible to retake, such as while hiking or traveling, I always set my camera up for a burst of 3 or 5 exposure bracketed exposures. I’ll do this for every shot.
It’s real easy to do and provides a huge safety net for getting all the details of a scene in a single group of images. During review, I’ll check the middle exposure to see if it has all the correct exposures. If so, the under/over exposed images can be discarded. If not, the additional exposures save the day. I find it’s always better to have too much information than not enough. After all, a digital image is cheap..cheap..cheap.
There are two types of clipping that occurs when the camera’s DR is exceeded. The first, which is obvious, is when all three colors channels are clipped. This creates just a single white or black blob with no information or details in it. The second, which is not nearly as obvious, is when only one or two color channels are clipped. You’re losing some detail but not all. This results in unwanted color shifts and muted detail. If you’re looking at a luminosity histogram, this won’t be evident at the time of shooting. A histogram showing the 3 color channels would, though. In almost all cases exposure bracketing eliminates these problems.
If you don’t need the under/over exposed images, then end of discussion. However, if that middle exposure has clipped highlights or blocked up shadows, then the other exposures provide the additional info to complete your image. There are different ways of processing multiple images. First, would be tone mapping/compression using a HDR processing program, such as Photomatix or Aurora. However, if you overdo it, you’re left with the garish images that HDR developed a bad reputation for. But better methods involve exposure blending where you take just portions of the under/over exposed images and blend into your primary image, usually the middle exposure. This is very common in RE and architectural photography. Tools for this include ‘luminosity masks’ and the ‘blendif’ tool in PS.
Some might argue that bracketing is problematic when motion is present, such a people walking or trees moving during a breezy day. Tools and techniques abound that solve those problems. Movement is not, generally, a limitation, unless to an extreme.
And then there's a whole discussion that could be had about multiple images for increasing image resolution (dithering) or noise reduction (averaging) in poor lighting situations.
YMMV, but I burst a series of exposure bracketed images as a regular part of my photography.
