16 or 8 bit?

I'm playing with HDRs right now and it gives me the option of saving in 16 or 8 bit. Is there an advantage to one over the other?

Well, this is one more of those subjective questions that you just might have to decide for yourself.

The simple fact is this: 8-bits = 256 colors per channel; 16-bits = 65,536 colors per channel.  Slight difference huh.

The arguments are these:
-(Pro 8-bit)If you are saving to jpg for printing, you are only printing from 8-bit files anyway, so why take up the room on your drives?
-(Pro 16-bit)You should always save and edit your files with the best possible quality to ensure the least amount of loss, and so you will have something useable in the future when technology reaches a point that it's the 'standard'.

I agree with the Pro-16-bit statement.  But I'm sure there are several here who don't.

You be the judge.

Also, realize that you do need to be able to edit your files without them becoming completely destroyed from capture to print, and the more editing done (especially with destructive techniques), the more problems you will have in your final image(s).

Because storage is cheap in the big scheme of things.

There's no such thing as too much information. If my camera supported supported 32bit capture I'd use it. Then again I'm the kind of guy who buys cars with a lot more under the hood than it take to go the speed limit in west Texas.

Sarcasm, frustrating the clueless since 3000 b.c.

Actually even if printing and displays are 8bit, working with 16 is still benefical...

Every time you filter an image you may lose quite a bit of detail if you are working with 8 bit. For instnace operations like curve corrections can reduce the number of colors significantly...

Basically you want the high bit depth not for your eyes to discern from 64k colors, its because it gives you more work space to edit more agressively...
