A while back, I read of some advanced camera systems that would take data from a series of images to create a single image with extended dynamic range (think night scenes where the lights are not saturated or suffer from blooming). Yesterday, I learned from a Popular Science article that this technology is available to all digital photographers now, and some geeky types have written free software to do the image manipulation. Hooray! I don't have to write it myself - I just get to play! Posted below is my first
attempt at making a HDR (high dynamic range image) Actually, the 32-bit image file looks better, this photo is my best looking one from 10 minutes or so of trial and error. Also posted is my best conventional shot of the same frame. Some flaws, such as the leaves blurred due to motion between frames, but in principle it seems to work. The sky is blue - not white, and the detail in the shady yard can be seen also. Lemme know what you think.I also tried the technique on a fire last night, and got a neat result. See?:

Holy so beyond me, Batman! But 10 minutes doesn't seem like too much trouble...I'll let Nathan think about that... So, uh, the picture with the blue sky... Was it actually more accurate, except for the blurring?
you planning on letting the other geeks onto the secret software code?
The leaves are a bit too orange, but otherwise, yes - I think the HDR picture is more like what one can see with the eyes. The secret software code is in the hyper-links in the blog.
Thats pretty bad news stuff (as in good). combining images in photoshop is pretty labor intensive.
I'm waiting for them to create ccd's that can adjust on the fly to specific areas that are receiving more light and dull their sensitivity accordingly (and vice versa for less light). Sounds like a technology nightmare to implement in any realtime sort of way though... Could it be feasible, engineer brother?
Went back and forth to see and compare the results of the HDR versus the conventional and indeed it is truly "better", "truer?" Mommy agrees.
Michael I wish I knew exactly what you and Dano were saying.
I don't understand any of this :(
I do know that I miss the bonfires!
Groovy man! Thanks for the tip. I like the fire shot as well.
