Nice capture there. I'm not familiar with P.S. Elements, so when you say you merged the two images, can you detail that procedure a bit more please?

And thanks.

Corel's Paint Shop Pro has an app to do just that, and it only works with RAW files. Many don't know it is there since it is under the "manage" tab, not the adjust or edit tab. From manage click on "File" and down the menu that appears you will see "HDR" that opens an HDR sub menu. If the image is not RAW or a form of RAW PSP recognizes the line "Single raw photo" will be grayed out.
Here is an image of a '71 El Camino engine at a car show in May 2015.

#2 the OOC done with a Canon 6D and 24-105L f/4 lens in very bright sunlight outdoors.

Actually, the option of "Single raw photo" is available from the edit tab. There are two ways to do it.
1) In the organizer pallet, right click on the raw file. Select HDR from the pop-up menu and the Single RAW photo option will appear.
2) In the organizer pallet, left click on the raw file and then click on "File" the HDR options will appear - same as from the manage tab.


I have found this to work quite well.

There has been many things posted about this idea, but I'd enjoy hearing specifics from those of you who have made this a study. Has it worked for you? And if so, did you do the over-exposure and under-exposure of the same image, while in RAW?

Teaching my students about the extreme dynamic range of your eyes/vision, I want to impact them to understand that even the best of cameras capture only a microscopic portion of that. But we can expand that with HDR, to make great improvements of our captures.

I would never argue that the absolute best way to do this is to shoot 3, or 5, or more, at the same time. However to do that, a tripod would be most helpful. But as I have traveled, a tripod is frequently forbidden. But a good overall single capture can be achieved with a good camera, and a good photographer. So let's talk about ways of taking this idea to the next level .... one capture and three images via RAW

I have done what you describe in the past but I am not sure you actually can gain anything by doing it that way. With a RAW picture, all the data is there in the single shot. I don't believe increasing the exposure on it a stop or two and saving a copy and repeating the process but lowering the exposure and saving it, then combining the original along with the 2 copies, will produce anything that you couldn't have gotten from just the original RAW shot. Photomatix and Aurora HDR both can produce good results from a single RAW shot.

I shoot with a Canon 6D, and have used its HDR capability with pretty decent success, even hand-held. Only thing I regret is that, unlike the 5D IV, the 6D can only do this in JPEG mode. As for giving an HDR treatment to a single RAW image in post processing, I've historically heard more negative than positive reactions. However, it appears that some of you are getting pretty good results that way, so I might give it a try. Strikes me that getting that right would need to begin with the exposure, where for most shots I'm guessing you would want the histogram to spill off the two ends of the spectrum to a roughly equal degree. Am I right about that?

James, With all due respect, have you tried it? I take it you have?

Yes, I did try it and then I also tried just using the original RAW file in Photomatix and in Aurora HDR. I wasn't disappointed in the results I got using the 3 copies but I don't know that I was able to gain any additional detail using the 3 that wasn't available to bring out in the original.

There is another person asking the same question at this time: https://www.uglyhedgehog.com/t-572750-1.html I (and many others) posted a reply there that might help.
