When making a HDR image can you only use RAW images? It's not working for me!
 
What software are you using?

You should be able to use 1 or more raw files and 3 or more JPG files with most software.

Am I right that you want to use Jpegs?
 
I usually convert 5 or 6 tiff files at .5 Ev from a raw file and generate HDR file in Photomatix (try not to over do it ) and then just tweak in CS3.

Basically i'm getting this error message.

I'm using 3 files in jpeg format.

@Steve, I've tried to repeat procedure you described but with Adobe Photoshop Photomatrix plugin. After trying to import 5 saved images, it told me that "there is not enough dynamic range in these photos to construct a useful HDR" Do you have any idea how can I accomplish creation of HDR image using that plugin?

@Anaderi, this is because there is EXIF information saved in the image files. Beacuse they are all saved from the same master they all contain the same EXIF info and therefore Photoshop thinks they all have the same exposure. One way to prevent this would be to use Save For Web to save the five JPEGs but it would be preferable to choose another format that can't hold EXIF information, like PNG.

Hope this helps
 
ok, so the next question is, how did you make those jpeg files? bracketed exposures or from a single raw?

Edit, forget that, the above is the answer (most likely)

You can do it either way to be honest. Moving subjects work better manufactured from a single file due to the ghosting you'll get with bracketed shots.

For full dynamic range posibilities, it's alays best to bracket your images given the limitations of manipulation exposure wise within RAW.
 
Good link PN.

As his quotes show Photoshop simply thinks that the pictures are identically exposed.

Yeah, I know that, but I was wanting find out what the OP did, as I've had the same problem in the past when coming from one RAW, which was leading me to the answer that Pirate Neilsouth gave if it is being done from 1 RAW.

Hi, basically I opened 3 images in jpeg format, one was over exposed, one was under exposed and one was exposed properly, I tried to use automate merge HDR option in photoshop but it said the photos didn't have enough dynamic range.
