Thank you.
And yes it looks better.
HDR means High Dynamic Range basically it is taking 3 or more exposures of the same capture. If you have bracketing in your camera you can set it at different Fstops this is where the 0, -2, +2 comes in so 0 is the correct exposure -2 means 2f stops under exposure and +2 means 2 f stops above the correct exposure so you will have 1 exposure at the correct exposure and you will have 1 exposure very light and 1 exposure very dark.

You don't have to use 2 f stops you can use anywhere from 1/3 on up to 2f stop differences. Nice thing about in camera bracketing you don't have to take 3 or so single shots at different exposures just 1 shot and the camera will bracket.
After you take the 3 exposures you bring them into a HDR program I use Photomatix the link is below.

In Photomatix you create your HDR image it is real basic you have about 15 different adjustments you can play around with then a HDR image is automatically created.
HDR is pretty specialized not all captures are made for HDR especially if you have tree branches, leaves, grass that sort and any wind you will get a pretty blurred effect in HDR.

Check out the link below it gives a pretty good explanation on HDR and you can try Photomatix full version free for 30 days. Program cost $99.00 and to me really worth it.
Hope this helps some
