How to manipulate the saturation of a HDRI?
08/29/07 at 20:53:35
 
... so my question today. Photoshop, sIBL, HDRShop1, XnView don't do it. Need I a new tool again? Could Photoshop CS3 do it?

Ciao,
Micha

Yes, Photoshop CH3 does that and much more.

You can use any of the Paint Packages from the Tools list, they should all be able to pull down saturation...

Sorry, more questions. What is the difference for 32bit image processing between CS3 and CS3 extended. I look around, but found no info.

Difference is huge. Extended will give you HDR layers and paint tools. I'm not 100% sure, 32 bit Saturation Adjustments might even be exclusive to Extended as well...

I bought CS3 upgrade some weeks befor, but forget it to install. Today I install it and saturation control works well. Layers are not supported, but I can select a part of the image, copy and paste it and move the inserted part. So, the most wanted basic works. Like you wrote, Paint tools dosn't work, but the copy stamp.

I tested to paint at a new layer of a 8 bit version of a HDRI and copy the layer to the original HDRI - it works. So, a basic painting could be possible.  Wink

Thanks.

How in the world can you forget to install that upgrade  Roll Eyes

Anyway - here is a dirty little trick, that worked since Photoshop CS2: You can open 2 HDRIs at the same time, lay them out on your screen side by side, and then use the Clone Stamp from one to the other. Just sample with Alt in the left image, and paint in the right one. This is how I used to patch HDR panoramas together... It's not as flexible as rubbing through real layers, but with an undo here and there it can be a powerful workflow.

When the "Clone Source" image is just large color swatches, you can even paint pretty smoothly with the Clone Stamp tool.... Smiley

I'm bummed out about the Basic/Extended split as well, the feature selection seems kind of random...

Thanks for sharing your experiences.

PS: I preorder the german version of your book at amazon.de.  I'm very curious. Wink

I guess PhotoShop CS6 can way better do the job.
