Playing with HDR (nerd alert)
 
Since I had no car I busted out my camera and tripod during the dyno day. I wanted to play with some HDR stuff so here are some results....kinda neat.

weird how it makes the doors darker, but i like the effect on mine:eek5:

Braineack 04-06-2008 05:19 PM

yeah, i could easily make it a little more uniform but these are my first pictures trying out the process....basically you take at least three images with different exposures and then you do a shitload of post-processing to combine them to get the best of all three.

ooh ooh, do me do me!

the orange car looks sweet like that. In all honesty I think it was the best looking car at the dyno day

Did you get inspired by Bens picture of his Mariner? I did. Here's my first try, I had slight alignment issues, and only the trial version of Photomatrix. Oh and slight alignment issues, it was windy.

I've been messing with photoshop for 4 years or so/since i was about 15 with no instruction as to how to use it. This is a pic from last year that might be considered hdr.

I like the last two you posted braineack, really brings the orange out, and I don't know why I like your last one.

kotomile 04-06-2008 10:12 PM

So, you take three images at different exposures and then.. what now?

I'd wager that most of us cheat. Take one image and manipulate the hell out of it with the various color / saturation / contrast controls. My skills pale in comparison, but this image was taken on a very cloudy day, in late afternoon:

Different day, a bit warmer but still late afternoon / early evening. There's something about the distortion in the background in contrast to the detail on the cones and pavement in the foregroudn on this one that I love:

BTW, Brainey- the sky in that last shot of the white car is amazing!

HDR doesn't work with moving subjects very well because you have to take multiple exposures.

There are a few how to's for HDR photography (Just search 'HDR Photography How to' in google)

I like to use Photomatix as it gave me prettier results. You just load the 3 or however many bracketed photos you took into Photomatix and select how you want them merged, adjust a curve (That's the hard part), then wallah!

Braineack 04-06-2008 11:08 PM

yeah i used photomatix for mine, it's much better than the adobe CS3 HDR automation.


here this will really let you see the difference....check out the shadows and colors in the background, look at the details in the wheels/tires and the asphalt.

Brain: What camera are you shooting those with?

Scott did you actually take three different exposures or did you just change the exposure using photoshop?

I'd recommend going with a larger gapping between exposures. You can do some really good stuff with HDR...man I need to find my camera battery charger.

Braineack 04-07-2008 10:28 AM

yep....i took 5 exposures each. +2 +1 0 -1 -2.
