Hi,

I have come across this tutorial:
NatureScapes - The High Dynamic Range (HDR) Landscape Photography Tutorial

and in one of the steps the author describes using Photoshop CS2 for the HDR workflow.

Hope this helps abit.
I am getting a fault msg "there is not enough dynamic range in these photos to construct a useful HDR image" while attempting to merge my 3 pic into HDR using PS Automate->merge to HDR function..... what does that mean ??

Maybe your 3 images's exposure is too close thus not much difference in dynamic range?

Anyway, photomatix generates nicer HDR images compared to Photoshop based on my experiences.

my 3 photos are bracketed @ 3EV apart.

I tried opening photomatix generated HDR file in PS, but unable to save it as JPEC format.
and HDR file seems to be alot over exposed when opened in PS, is this normal ?
plse help... thks

thks.... actually what I meant was, after generating the HDR image in photomatix + tone mapped.... there isn't a JPG file option in the SAVE AS, hence I saved it as TIFF, and I open the photomatix HDR image in photoshop, it also doesn't have a JPG option in the SAVE AS.

HDR files are 32bit/channel. U have to change the setting to 8bit/channel before you can save as JPEG. Hope this helps.:)

No prob. Can share your HDR pic? I am trying to learn HDR too...but my S3 IS can only expose upto 15sec...:(
actually I just started ystdy. took a pic outside my house, still trying hard to learn the tone mapping, looks like Photomatix can generate a much better HDR image than PS. post my lousy result in a minute.....;p

I bracket my exposure in an increment/decrement of 1EV, total 5 pic were taken. i.e. >> -2EV, -1EV, 0EV, +1EV & +2EV. REMEMBER to use tripod hor..... unless you have damn steady hands

you can try Photomatix trial version to merge all 5 pics follow by performing a tone mapping & finally save.

don't bother to use PS, result not as good as photomatix.

Hi yilishengxian,

Thanks for sharing. Did you using Exposure bracket or shutter speed?

and I think your "Signature" on the pic can be improved abit...it's slanted and the font is a bit out for the pic.....hope you dun mind my opinion.:)

I having been using shutter speed rather than exposure...is the photomatix trail time base? 30days only?

TADANG...... MY 1st HDR... don't laugh hor.:embrass:



as you can see... there are watermarks printed too, its trial version, thats why.

I used exposure bracketing and continuous shooting to get 3 different exposures of the image of +/- 1.5 EV. Then used photomatix to create the HDR image.

As for my signature. I'm using a new one, but its slanted too :) and the same position. Personal preference.
