They touted it, yet I can't seem to find it.

Anyone know?

nm, Tuaw had the answer:
If you have an iPhone 3G or 3GS, you'll have to buy an app to get HDR photos, because Apple HDR requires an iPhone 4.

bummer

Speaking of which if it is taking 3 photos, wouldn't this fill up your space pretty quick?

not sure how big the iPhone 4 images are, but the 3Gs are 1.4MB, so it would take a LOT to fill up my 32GB iPhone.

Besides, you would eventually delete those that you don't want or transfer them to your computer.

I used it 2 days ago. It will take a regular shot and then it pushes/ pulls the exposure to make 3 shots. It doesn't take 3 separate shots.
It works ok... opens up the shadows some and pulls down the highlights. Just a wee bit, but enough to make a difference. You can set prefs to keep only the HDR or both.

I'm still on the fence about HDR. If done properly, they look good. But I have seen a lot out there that look like crap.

The iPhone app doesn't alter color... just marries the exposures.. as far as I can tell so far.

I swear it was supposed to work on more than just the iPhone 4. I gotta watch that keynote again.

Thats interesting
Still it has to pull exposures and it claims that it saves a before and sorta an after shot so you can compare. Anyway it has to eat up some space?

They are not saving a copy, but like Version Cue in the Adobe Creative Suite it saves the info on what changes to make in small text file, or for this maybe just text embedded in the photo which would add no space. Not sure how much a text file takes up on the phone but on a computer it's anywhere from .5K to 4K.

A photo is 1400K. If the text file is 4K, It would take 350 photos to "eat up" the space one photo takes. If the versions are saved in a text file, all depending on the size of the allocation blocks, .5 or 4K, out of 3000 photos you would probably get 1 to 8 less. The space used is not a factor.
