32 bit photoshop CS2?

Actually, that's not the main point of it.

theoretically it's possible to capture multiple RAW images (ISO
bracketing) from single exposure on CMOS sensor. Sadly, camera vendors
that use CMOS are not innovative enough to even try it.

Hmmm. "InstaBracketing (TM)" sounds like a plan. It would be
nice to get the effect of HDR (with possible extended write
times to store the results) in-camera. If it does happen, I'm
guessing Nikon will NOT be the early adopter. :-(

Hi,

I guess
the argument some people make is that you don't need more bits than
what you can ultimately display. That's not true in my opinion. The
extra bits provide lots more opportunity to manipulate and edit the
image without losing colour resolution in the final 8-bit image.

I'm using a Canon 350XT shooting RAW. I open these images in PS CS2 as
16-bit images and tweak them before finally converting to 8-bit images
for saving/printing. I think (belief system) that working on them in
16-bit mode offers a wider color gamut and superior output. But that's
only my "belief" system. I may be wrong.

There are some oddities in the images. Like the glow in the reflector
image
or the blue sky tone gradations in the Photomatix example image on
their home page.
But the images look good.

I heard you cannot use multiple RAW conversions of the same shot though.

There would be no benefit in doing so; the whole point of HDR is to get more
range than a single shot is capable of capturing. If you only have one shot,
you can just use the normal image.

I can get a lot out of a raw file with different settings in two
passes but it's hard work merging them.

Learn "curves" instead, and you'll never have to do that again.

Oh, I know curves but don't have CS2 yet so can't apply to raw. The
Camera Raw adjustments do more than that though. With CS1, I can reveal
wildly different parts of the exposure with different settings.

My point in this thread (and the previous 16 bit one) is maybe exporting
to larger gamut or bit depth would allow better control in PS but it
doesn't look like it.

Yeah, CS2's Camera Raw curves make that obsolete.

Besides being coarse in control, it is incapable of addressing anything
outside of the blackpoint and whitepoint determined by the exposure,
contrast, and brightness settings. It really isn't much different than
working with curves after the conversion. IOW, it is *NOT* a RAW curves
tool.

Sure it is; it's just not the one you want.

It sounds good, whay isn't it *real* RAW curves? There are other
adjustments in Camera RAW though, which can be used for multiple
conversions with masking.
