I like it although it is easy to over do the saturation and processing strength resulting in wierd halos. This was my best result I used a program called Photomatix. Thanks for looking.

show us the correctly exposed 8-bit image so we can compare please

I had a very difficult shoot for a client - huge differences in the light range - I solved it with the HDR option in Photoshop CS2. The detail in all the dark places came to life - I'm a huge fan of this technique, although it is labor intensive

what'S HDR?

HDR = High Dynamic Ramge; it involves merging two or more exposures into one.

Ty, it would be useful to us to see the originals, or we can't really judge what was done. It's a fun process, isn't it?

YOur image here shows one of the liabilities of the process, however; it's possible to flatten things out unnaturally. The foreground, especially, has no life in this shot. And of course you are having sky issues, as you pointed out.

Practice will make perfect; I've used the same program myself.

I will post the other images tonight because I dont have the copies on this computer at work. I did bracket 2 stops over and under the normal exposure based on the cameras meter. Making for 3 images. Here is a link to view a less compressed version because the DPC compression takes abit of contrast away from the image when resized. Although I probably would not use it for a professional job I do think it is fun as an artistic tool.

for Photoshop CS2 you shoot your image as metered - then +/- 2 and 4 stops using the speed to bracket (aperture changes your DOF and really screws up the shot - or makes it artistic)for a total of 5 images (although I think 3 would work too).

Then when you combine them into the 32-bit image, it allows you to set the light level you wish for the final image. Editing in 32-bit mode is VERY limited, but I've found that resetting the light level in the shot, converting to 8-bit, and combining the 8-bit images gives you a huge amount of flexibility.

I'll post my 8-bit and HDR images in a few minutes.

digitalknight-

Thank you for the tips I am going to explore HDR much more, your tips are no doubt very helpful.

Thanks again

HDR


Original


I only remove the wall elements and straighted the lines on this HDR image - so the exposure hasn't been messed with at all in Photoshop - other than turning it into an HDR.

Thanks for reminding me how cool this technique is. I'm going to try it with some studio stuff and see what that yeilds.

Pretty exciting shot, no? It's a glamorous life I lead. The client LOVED the shots of this building, and I made enough on this job to pay for my camera and lens - taking photos I'd really rather not show on DPC! LOL. Gotta give the client what they want - and this looked great in their catalog (industrial lighting).

This looks great. There's a dramatic improvement in the light over the original.

I've been thinking about posting some questions about HDR, but haven't gotten around to it - thanks OP for showing what you're doing!

We have some users here who have some nice HDR work outside of DPC. Floffy has some really cool looking HDR images at //moodaholic.com/. That's what inspired me to take a look at the technique. I want to try it with CS2, but it's really time and memory demanding, isn't it?

I have a dual G5 2.0 with 4 gig of RAM - it used to be a fast computer - but the files are HUGE in both hard drive and RAM requirements - as far as actually putting the HDR together, it's pretty quick on my machine.

It seems the HDR took 180 meg for storage, and used the lion share of the RAM (2 gig) that CS2 had allocated to it. So they are pretty hefty.

Hope that helps.
