HDR manualy done -no photomatix, no Merge to HDR

chansh · 18th of May 2006 (Thu)

Had a play around with CS2's "Merge to HDR" but the results were very disappointing. There were no contract, lost of details and the colours were horrid.

SO, I did it myself.

Tell me what you think.

Looks quite nice indeed. Care to share your secret?

Yes please!

You've got some awesome results.
I've played a bit with HDR on CS2 and found the results and control over them were a bit disapointing. Haven't tried Photomatrix though.

Both of the pics was a 3 image merge. Using the video here.

Top one looks like a drastic overuse of something in the sky... perhaps Shadow/Highlights?

these are nothing to do with HDR.

HDR's are 32-bit images, which in order to view on a computer monitor require a tone-mapping conversion to 16 or 8 bit.

Extending the dynamic range of an image using exposure blend, or using shadow/highlight aggressively produces an IDR (increased dynamic range), not an HDR.

I do have those pics as 32-bit images. Therfore they are HDR. I just had to save them as jpegs to display them here.

Now we're comparing increased dynamic range and high dynamic range....we should be politicians...

as far as I'm aware it's impossible to create a 32-bit image manually.

how did you merge them to make a 32-bit image?

I ain't making this up. There are specific definitions for different processes, and there seems to be a bit of confusion over what constitutes actual HDR's compared to alternative techniques.

I watched the video, and you are wrong.

The above are NOT HDR, they are just "more dynamic range"...

It looks good, dont get me wrong, but it aint HDR. You cant tone map or or merge to HDR and get the same results. I can tell the difference beteween TRUE HDR and homebrew.

Try photomatrix, its a totally different ball game.

Also, if you look at the shadows in the windows, there is no dynamic range to them...

And just becaues you have a 32 bit file, does not mean you have HDR. My HDRs arnt even that great, im still learning, but there is a lot of science behind one of them.
