I want an opinion from more experienced people in the art of HDR. Yestarday was the first time I went out just to take cityscapes and architecture photos. A mistake nevertheless,as the sun was burning the atmosphere with 35 degrees C,no clouds & I had to put out with a lot of people & cars passing by & of course,all sorts of unwanted things,cables & commercial adds. (love my city...)
2 HDR samples of the same frame:

Can someone explain what a HDR is?
Is it a composite of one photo like 3 of the same layered on top of one and another?
This is how I learn , I ask questions! Thanks for any help you can give.

Nice attempts, but can you see the halos ? It looks as if the buildings are glowing.

HDR = High Dynamic Range.

Meaning it's one shot, composed of anywhere from 2-10+ different exposures so that the Highlights are well exposed, and the Shadows are well exposed.

The image would not have any underexposure, or overexposure.

One of the best programs to perform HDR work with is called Photomatix.

You combine 3+ exposures of the same shot, and generate a HDR image. Then you proceed to Tonemap it to get the "HDR effect" that you see everywhere.

Best,
-Sean.
