I am not sure which camera you are referring to when you say a one shot HDR camera. Nikon's D7100 (and the follow-ons) do a one CLICK HDR. But the camera actually takes between 3 and 6 shots and combines them into one HDR shot on the camera. Is it perfect? NO it isn't but it is a decent HDR shot. Personally, I go back and forth between it and actually shooting somewhere between 3 and 7 shots on a tripod with my D7100 and combine them into HDR shots. It does, however give photographers that might never consider shooting HDR a beginning at doing so. By the way, the D7100 also has the ability to allow the photographer to program the type of HDR he or she wants to shoot (without the "auto-HDR" by telling the camera to take x number of shots and adjusting time, aperture, between shots automatically. But a one shot HDR? ummm No!

I do take one shot, then copy the photo and make it that way. It is easy in Photomatix 5.12

Photomatix Pro will allow you to Tone Map a single exposure, creating a HDR image. However, if the dynamic range is outside the sensor's capability to capture detail, it will be missing in the scene. I have done some tome mapping of single exposures with pretty good success.

Um...if this were true, then how did I shoot this?
Handheld, moving subject, HDR, stitched pano...check. Must be my mad skills :-)

Nice shot, and I agree with you. I shoot multiple exposures for HDR processing, handheld, all the time. Works great most of the time.

Another way to say the same thing is to suggest shooting in RAW mode. Then your HDR processing software could adjust the exposure to two or three different levels and combine those images using HDR. So far as I know, all software that is capable of HDR processing will support this operation directly, but there could be an exception. Even then, you would only have to create multiple images with different exposure levels and then use the HDR software for the HDR merge.
Certainly with Photomatix it works well with a 1 shot RAW file and can save a wanted -but poorly exposed - picture from the bin.

Fuji has ISO bracketing up to 1 stop for 3 exposures of the same image. Works pretty well in Photmatix.

My Pentax camera has an HDR setting. Once set, I loose ISO 100 and I can use any ISO from 200 any up.
Just guessing but that might be similar to Nikon where some of those start at 200 all the time.
Another thing, even though newer Pentax cameras have this setting, I can still normally pull out plus four exposures or minus four exposures from the origional RAW shot in my post edition software, Capture One Pro. It's four as long as it's not blown out or super black to start with. I would think eading your artic km e about post editing or not, I fully agree with your thoughts except in certian situations.
The biggest reason to alter photos is because some, (seldom for me), photographers have a branding that basically means a sure all photo. Most of those type photos just aren't available in-camera. I would think the other major posy editing programs can do this also.
(For those interested, see any any articles on the Local area Adjustment control. It's fast works great.)
Most of the time I only use post editing and manually make an HDR mod that I want.

Sounds like a good idea. Why don't you start a company, hire some geniuses and make a lot of money.

To me it sounds like you want a camera that you can just point at a scene and not have to worry about any settings until after the fact (select your ISO, speed, aperture, composition, special filters, and focus point in post-processing)...but what fun would that be (probably a lot, but that defeats the purpose of this response). Personally, I like to think about what it is that I'm trying to do before pressing the shutter button. That's what helps set you apart from photographer next to you.

It's an idea if you're after HDR which I don't care much fore. I don't have enough money to start a company. Don't need geniuses to do this, it's a rather simple process. No not making a lot of money as I don't think it will sell.

Sony's Dynamic Range Optimization (DRO) is the single frame, in-camera equivalent (kinda) to HDR. One photo "worked" in the camera.
D-Range Opt. (DRO)
"By dividing the image into small areas, the product analyzes the contrast of light and shadow between the subject and the background, and creates an image with the optimal brightness and gradation."

This could easily generate a lot of controversy. The new camera sensors are excellent in their dynamic range and opening the shadows up to three stops is usually a very real possibility without side effects.
I have no experience with in camera HDR and obviously I have never attempted to do so. I do use software and it makes it very easy for me to get a good HDR from bracketed exposures with the added bonus of being able to use excellent presets incorporated into the program, apart from the many parameters for further manipulation of the images.

You said just what I was going to say (glad I read through the postings first!). I have a Fujifilm Finepix S-1 bridge that works the same as your Olympus, though I don't use that built-in HDR function much, preferring to make my own. I use Photomatix Essentials 4 (Though I'm still in the tyro stage as can be seen by the attached). The pictures (5 of them) were shot just before dusk, and my intent was to highlight the early spring Red Bud Tree flowering, which lasts for just a few days.
With the camera on a tripod and set for aperture priority (I used f8 throughout), spot metering and ISO 100, I shot 1 at normal exposure as a base, then 1 at 1 stop over and 1 at 2 over (highlights), then 1 at 1 under and 1 more at 2 under for shadows. In each shot it was of course the shutter speed that changed, nothing else. Photomatix did the rest. I planted those trees as little foot-high saplings back in '93, when this house was built after I retired from the Army.

Bingo...on the RAW thing. The auto-generated HDR from my EM-1 produces way over saturated images. I much prefer to control all the settings myself in post.
