| Does anyone have a good link for tutorials on tone mapping in CS2 (not using Photomatix)? |

BUMP! (because I would like to know, too). ;-)

| Tonemapping or HDR? By default, you cannot tonemap (to get that classic Bear_music or MAK looking image) without using Photomatix, although you can generate HDR image using CS2, but they wont have that same `feel` about them.. |

| In certain situations, the Highlight/shadow tool will give you the tone map feel. I'm not sure if there is a "real" way to or not. |

 Brad told me, when I asked the same thing...that the shadow/highlighting option gives a similar effect to the tonemapping. Seems like it could be a good alternative? :) |

Converting to 32 bit ... then back down will automatically open a menu allowing you to adjust tone mapping ... there are 4 options and some are more editable than others - see md8speed's music image. He also used some other tools to creat this sweet look (see description)

Tate - thanks for that bit of info. I knew that highlight/shadow was a possibility, but I didn't think about just converting to 32 then back to 16 to force the tone mapping menu. I will go and play with that later - thanks again. I honestly don't see myself purchasing Photomatix just for its tone mapping capabilities.
Magen and Les - let me know if you play with this technique and end up with anything interesting. If I find the time to play, I will upload an example here... |

I used the shadow/highlight tool for this image. It really brought in the sky and evened out the rest of the shot.

I'm experimenting in PS and have great "tone mapping" effects when I use "Local Adaptation" histogram of the HDR Conversion dialog, which I invoked by changing image modes from 16-bit to 32-bit and back to 16-bit.
I may post a photo here that I'm working on. I say "may", because if it turns out decent, it's going to be my 11th-hour entry in the Free Study for this month.

I actually just tried that 16-32-16 thingie myself, and it's interesting; I'd not been aware it even existed. We sure are getting a lot of options these days, aren't we? :-)

Nothing near as good as md8speed's shot but in the HDR challenge I used the same technique as him for my entry:

Just checked that one out; it's EXTREMELY noisy. It's a major "effect", and it's actually pretty interesting but I think it would be doomed in the eyes of challenge voters.

I have tried playing with hdr in photomatix and PS2
My question is this...when you are creating multiple exposures from one image... I have heard reference in the past to using curves to create the images..I have also tried exposure and gamma but I often get the message that there is not enough dynamic range..
So, is it my conversions or is it more to do with the original image? |

If you are getting "not enough dynamic range" than you need to lose the exif data on the additional "exposures" you create. In other words if you are using one raw file and creating 3 exposures out of it chances are you are saving all of them with the same exif data and when photoshop reads them it thinks they are all exposed the same thus it doesn't see the increased dynamic range. The easiest way to remove the exif data when saving is to first copy and paste the image into a new file and then save the file. Do this for each one and then try your HDR merge.
ETA: If you are doing this from one jpg file make sure you don't over write your original in the process.

yes it's powerful... I have used it some challenges with response from bad to favorable. It has to be tamed, and subdued to be usable. It can be used in 16 bit and possibly 32 bit, I can't remember, in conjunction as part of ps tone mapping tool/array. It is interesting.
This would be one example where I used it. I have a few others in my port.

OMG thank You!! I have been going nutty trying to figure that one out!
Not only do you have great taste in cats, you are all helpful n'stuff :) |

just tried it quickly and I like it, I'll try it more later, thanks for the tip md8speed! |

Here's another, different photo (before and after) that I Tone-Mapped using Local Adaptation within Photoshop (16-32-16)...

no post-processing . . . . . Tone-Mapping via Local Adaptation
I think I like it!

OK - just finished the 16-32-16 method. Quite interesting. These are not the same results you get from simplly using shadow/highlight. The curves interface in the local adaption dialogue is perhaps a bit more familiar than the optional controls in shadow/highlight.
Thanks for the stimulating conversation! |

How do you convert an image to 32-bit? When I try, the option is grayed out.

did you go to 16 bit first? If you did that then make sure your image is not in grayscale too. Hope that helps. :) |
