I'm hoping we don't end up with a gazillion HDRed images. Talk about boring.

OK, that was bright.


Would you have known my gulls and my stormy vertical landscape were tone mapped if I hadn't told you?

You're talking about which 2 images now?

Thanks. Those 2. Yeah, I think I would have suspected. Both of them look "unnatural" to me, in a way that is consistent with images that have been HDRed.

Look, to my eyes, what HDR treatmets often do is make light look funny, HDR sort of changes the light in a way that makes images look strangely flat yet very colourful. It's just too much, it's fun for a while, but I reallly find it tiresome.

Gulls - no (wonderful photograph BTW). Landscape - maybe, would have considered it, but it looks fine.

Now, I understand with CS2 shadow/highlight you have that ease of functionality too, but I don't have CS2 (can't run it on windows Me and my slow machine) and I consider Photomatix Pro to be my version of shadow/highlight. When Deb was here I played with CS2 a little on her laptop, and as far as I can see they are pretty analogous until you get to extreme contrast situations, where tone mapping has a distinct edge.

Robert, CS2 isn't required for the Shadow/Highlight command, I have CS (which I thought was the version you had) and it is right there at Image\Adjustments\Shadow/Highlights...

For my eye, your images show the tonality I would expect my eyes to pick up if there in person (pushed just a bit, perhaps). The only unnatural aspect of it is the forced 3D effect that is created. It takes a bit of getting use to before seeing 3D effects as strong as with your gulls on a 2D surface.

That is the only forced aspect I see in your images, the tones look fine.

Robert, I agree with your assessment of the relative capability of HDR/tone mappng and Shadow/Highlight. The latter is good for moderate adjustment, but when there is extreme contrast range to compress, it calls for a more sophisticated approach.
Your use of mapping is outstanding. So many HDR images are immediately obvious, and if that's the case, the technique has utterly failed. Your implementation, however, is strong but subtle, and the end result is outstanding. I do like the tone mapped version of the sunset much better than the original. There's much more detail in the darker tones, and the image has more impact, IMO, even thought the saturation is lower overall.

I was using the trial version of Matrix Pro, and it made the image really noisy... It works a lot better than HDR in CS2 but the noise bothers me...maybe it was just that image...

Interesting, but over the top a bit for me on this one.
 11/10/2006 02:27:53 PM · #60
I guess it's an opinionated subject, 'cause I like the snowplow. The after shot has a lot more exposed detail.
 11/10/2006 02:45:07 PM · #61
Here is my attempt at tonal adjustments.


The before shot.

I just bought a copy of Photomatix, and from now on I'm going to use it for everything.
:-P

I have been trying. But I keep getting a message telling me there isn't enough difference in the images I am using to make a useful HDR photo, Not exactly sure how adobe knows exactly what I would determain useful, But thats whats happening.

I agree it may be a little much but those are things that can be tweeked. These examples just show how you can take a not so nice shot and make something usable out them if HDR is a suitable alternative for the photo. I agree not all photo are suitable for this type PP.

I manage to get rid of it pretty fast!

it looks kind of un-natural

My first HDR. Had the images about 6 months before I could process them (Photomatix)

Everything from the bridge and above seems to have worked out quite well. The water looks a bit cartoonish though. (IMO)

Could someone on the site council (here) explain how the Basic and Advanced editing rules relate to HDR? Please address multiple files, single files with multiple raw processings, single files that were processed once as raw but were later re-processed as multiple and re-combined filesâ€Â¦ etc. etc.

Is there a way to avoid the highlight/halo affect that I see so often in HDR processed photos?

At least with Photomatix there is a control that reduces this effect, but it also will reduce the contrast. That halo effect seems to be how it can create an HDR image with reasonable contrast -- different parts of the image that originally had different tonal ranges get mapped into the same range which creates a halo-like border.

Sometimes it works, sometimes it doesn't. It's very dependent on the subject.

It's just like USM, basically; overcook it and it halos like crazy. There are 4 different controls to balance in Photomatix Pro, and if you get it right you won't have the halos. Another problem is the creation of artificial contrast in flat areas like blue sky, and still another problem is the artificial graying-out of white areas. I'm still learning how to do it well.

Is it me or most HDR images makes you squint because of the brightness of the entire image? I can't look at them for too long .
