    I didn't want to hijak Kanikula's thread in Wedding and Portrait Photography, so I think this is the most appropriate place to ask this. I know you usually do HDR from multiple images at different exposures, but there is a way to do it from a single exposure (as seen in the HDR Bride and Groom thread in the board listed above). I've tried, but I keep getting a message that says my image doesn't have enough "dynamic range". Can someone walk me through this, step by step, using RAW and Photoshop? :hug::

    Well, that leaves me out, I guess. I own CS2. Has anyone tried the workarounds mentioned in the link?

    Err it makes no sense to call this HDR. Call it what it is. Tone Mapping. Even from a single raw with multiple exposure adjustments there is no additional dynamic range.

    Even in CS2 this can be done. Just convert a single image to 32bit and then back to 8bit and you'll get the ToneMapping box up. Not sure if there's another way though.

    I would love to know who it is that decided to play with some curves and tonemap a single exposed image and then call it HDR :angry1:

    Hahahhaha...You're right, of course. :hug:: I intend to play with the traditional HDR format with the bracketed images. Does CS2 give the same error with those?

    Error? Not quite sure what you mean.

    High five. :thumbup: I believe I tried to say this earlier. (mentioned thread)

    wildmaven:
    Look into picking up photomatix. Its a great HDR program, and it will let you do the tonemapping progress your speaking of. It makes HDR & Tonemapping very easy and effective. Its pretty cheap also, you can try it for free befor you buy it to see if you really like it.
