I'm talking here of the "legal for advanced" for of HDR, where it's all one RAW file at various exposures.
In Adobe Camera RAW, I've tried saving DNG files at several exposures, but when I try to combine them into HDR, it tells me there's not enough dynamic range. But when I look at the +3 vs. the -3, it's clear they're far away from each other in terms of brightness and histogram.

You're gonna have to strip the EXIF from the files and manually enter exposure info for the shots.

Huh? I change the exposure using the sliders in Adobe Camera Raw. I don't even know how I'd do either of the things you mentioned.

The easiest way to strip the EXIF is to open each conversion into Photoshop.
Select All
Copy
Create New Document
Paste
Flatten Image
Save (Image 1)
Repeat however many times you want.
Now when you go to use the HDR dialog it will ask you to enter the exposure data manually. You'll have to tell it how many stops each conversion was from one another.

wouldn't save for web be slightly faster? (as long as you don't save over the original) |

I've had issues with full-sized images and save for web... might be a memory thing for me though. But yes.

If you use Photomatix, you can just drop the RAW file into it and it can then generate an HDR image, which can have tone-mapping applied.

| You can also tone map from a single file in CS2. U just import as a 16 bit file then change it to 32 bit and then back down to 16 bit, you will get the HDR dialogue box will come. Here is a DPC tutorial. It works, can even be used in Basic editing challenges i believe. |

| I read this tutorial but I'm not sure how to import as a 16 bit. Can someone explain this to me as I would love to give HDR a go as well. |

If you convert a raw file in Cs2, one of the drop down menus on the bottom left lets you choose 8 or 16 bit. Technically you can go from 8 to 16 to 32 and then back down to get the dialog box. When you have an image open go to Image->Mode, you will see a check box next to 8 or 16 bit. click the 16 bit. Make sure your image is flattened and got to image->mode again and select 32 bit. It won't look any different, then go image->mode and go back to 16 bit the HDR dialog box will come up and go to local adaptation, and click the histogram button and you will get a curve to play with. Hope that makes sense. :) |
