some HDRI's

[misterx]

The batch from the tunnel didn't work out due to a lack of bright data (I really did need the tripod after all) but I think I've got the hang of it now with properly exposed photos and the newer software. The photos show some differences due to variations in the settings... I'm still deciding what I want these things to look like.

HDRI = High Dynamic Range Imagery. Take multiple photos of a wide contrast scene, varying the exposure up and down to capture the full range of data available. Using special software, you combine the images, and use tone-mapping to convert the scene-wide contrast into "micro-contrast". This compresses the tonal range a bit, and enables details that would have been lost to come through.

Here's some images I made a couple years back to explain it...

Nifty. It's like shift tilt, in reverse.

Nice. So what do you do HDR in - Photoshop, Photomatix, something else?

I love HDR, these are great.

It gives them a bit of a painted effect.

these are so beautiful, I'd love to have prints of these, I'm in awe.

I love the first picture and the last one.. and the third one. They are great. :)

Wow. The lighting from this method is surreal and best evidenced in the image of the house and the color photo of the tractor. For a moment, I had trouble telling if they were real photographs or highly detailed 3-D imaging models. ^_^

wow. I'd love to be able to do that. I was actually playing around with the exposure level at the quarry but wasn't sure what kind of effect I could gain from that. I think I asked some question about that at some point. How expensive is that photomatix software?

I think that HDR works better with the manmade objects - especially #3 and #5. I do my pseudoHDR using Photoshop's Shadows/Highlights adjustment which closer simulates what our brain does with our eyes' image data.

#3: fucking amazing.
