Here is an example of HDR. I mean, you could go into the technicals, but its about creating a single image that has a HIGH range of colors and contrasts. (Fair warning, its been a while since Ive done this, I might have gotten my f-stops backwords).
Example, this picture was taken with the low fstop, see how the sky is taken nicely but the front trees cant be seen.
This was with a high fstop,
The trees can be seen but the sky is very bland. There isnt a simple way of capturing both at the same time. So HDR comes in, "blends" the images, to where both the sky, and the frontal trees can be seen.
What is not an example of an HDR?
Why is it not HDR?
This, everything can clearly be seen ,the far off light source (sky) has no details, the f stops are pretty much the same...
Great panoramic view though
.
I suppose if your going for that "hand painted" look then yeah, an HDR image would suit you, have fun
.
Oh yeah, I used photoshop for the first photo. And the second with
this (free) program.
