HDR to Jpeg?

[Tygr1]

Newb here.

What do I do with an HDR file? How do I get it back to a usable Jpeg?

Much thanks in advance!

Tone mapping (http://en.wikipedia.org/wiki/High_dynamic_range_imaging).

That worked, but does this mean that I cannot use the 'Merge to HDR' command in CS4 to end up with a Jpeg file?

No idea, I don't do HDR. I would be posting in the HDR subforum if I were you. Maybe they have a FAQ. Google will help you find information too.

You can use Merge to HDR in CS4 and then change the Image Mode to 8 Bit & you will then be able to save to jpeg. Granted it is not that easy, you have a bit of work to do in between. I admit I am just trying out HDR, I would suggest taking a look at the Photomatix product also, everyone seems to recommend it over photoshop for HDR.

Good luck.

Doh! Glen S. thank you so much!

Once you end up with a 32-bit file in Photoshop, save it as a 16-bit file and then you have to mess around with the curves until it looks right. You're basically compressing the tones into a smaller space so this requires some artistic licence.

Photoshop will typically produce more realistic images but Photomatix can produce some artistic images... but expect plenty of button pressing and slider sliding along the way :)

Great advice JoYork, thanks much.

When you change to 16 bit, scroll down to Local Adaptation, and adjust the histogram. CSx does not do a very good job at producing the images you see here. Photomatix, Lucas art plug(not real HDR), Topaz proggies(not real HDR either), Dynamic HDR, ..... I like Photomatix, and DHDR the best, but have not tried them all. DHDR is the better program, IMO, as it has many types of blends/mapping flavors to choose from.
