HDR

Here's my disclaimer: I am not an expert at HRD photography.

HDR or High Dynamic Range is a niche in photography where you try to have a perfect exposure by blending 3 or more pictures taken at different exposure settings to create one picture perfectly exposed.

(did that make sense?)

Basically, with manual photography, the camera reads the amount of light going onto the camera and adjusts the shutter speed for the amount of light going into the sensor so that you can have a "theoretically" perfect exposure. The problem is that most photos include sky and a foreground that do not have the same light levels. So what you get is either a completely blown sky (white) or completely dark foreground (black) and a nice blue sky.

Well, HDR works in blending 3 photos into one so you bracket the exposures: one for sky, one for "mid-ground" and one for foreground.

It's an interesting technique and one that I want to try to pursue a bit just because the effect can me really dramatic.

The following pictures are not the best ever, but it gives you a feeling of what HDR does.

It's a neat effect and it will offer an image that is a bit unnatural because our eyes are not used to seeing something so balanced.

But hell...it's a new thing to try and it was fun trying!
