Single RAW vs. Multiple Exposures

What are your thoughts on this? If I'm honest, from all the HDR's I've been looking at recently, I can't seem to tell the difference!

I have to do mine from a single RAW as I have a D40 and tend to shoot handheld, then convert to multiple files using Lightroom.

I typically will only use one RAW when there is motion involved. This shot was taken of a palm tree blowing in the wind, multiple exposures would have an unfavorable result:
Blowing Palm Tree

However, here is a shot taken from 3 exposures around the same time:
Key West Jetty

There is noticeably less grain, and more detail in the clouds. Whereas the highlights in the clouds tend to get blown out in the first one.

I've been using PS to generate three or four separate TIFF's, Tone Mapping in Photomatix, and back to PS for adjustments with Curves. All from one RAW file. It only takes five minutes and I'm fairly happy with the results. Here's one of my first attempts:

Smoke On The Water

You can get a simple result by going to File>Open in Photomatix and Tone Mapping a single RAW file: no need to generate separate exposed images. Gives a Psuedo HDR file.

Acutally, most of my "good" (read: interesting) HDRs have been from single exposures and, like others, pp'd till i was happy with them

wickd, any chance of posting the orginal file to compare?

And I agree, your first shot has quite a bit more noise than the 2nd, the 2nd one also has richer colours.

all one file makes is a tone mappable image.... i do it all the time, works out well but not as well as a true hdr, multi shot image.

the thing about using only one raw file, is the fact that although you vary exposure and combine what you have done, you don't have any more information than you started with. the dynamic range is still limited to the single shot. i have tried the one raw way, and combining 3 or more bracket shots looks so much better.

wickd, out of your two pics I actually prefer the first. Though, to tell the truth, on first view, and without looking too hard, it's difficult to tell the difference.

I believe that an HDR multiple exposure still got the richest tonal value one would need for a really awesome image but this depends on situations your in. As wickd mentioned, you can't get good
results shooting a moving subject or in motion. And that's where shooting single RAW file(s) can be handy!

There are other flickrians are using single raw, you might be surprise of how detailed the photos when it is done.

HDR is not all of that in my opinion, it still need more, it needs a WOW factor. Blending and twicking is involved.

for me, single RAW or multiple exposures could both work well. I use single RAW on moving objects, but i like to use multiple shots whenever i can because of the wider tonal range

just tools... different tools for different jobs. I use 1, 3, 6 files, lucis, buzz pro, photomatix, PS.... lots of layers, filters.. anything i NEED to do to get the outcome i want.. I say just have fun with it, using one or 50 exposures doesnt really matter much as long as you like the outcome!

I've been playing with HDR lately, and ran some quick tests yesterday. I shoot in RAW+JPG pretty much all the time. Using Photoshop's Camera Raw plug-in, one can generate differently exposed JPG files from +4 to -4 exposure value. I noticed with some of my recent HDR attempts that my in camera shots using the AEB feature (takes 3 pictures, 1 properly exposed, 1 over exposed and 1 under exposed) that the alignment wasn't close enough and I was getting some bad ghosting. So I set out to test and see which result gave the best HDR image.

I wholeheartedly agree with definatelyoverdone. HDR from single RAW's is just another method to obtain the result you desire or happen upon. Just enjoy the process and mess about with it. Unless, of course, you're a purist!

I agree entirely with Definitelyoverdone. What matters the most is the end result, and what ever steps you take to achieve that are mere trivia in comparison.
