I'm very much attracted to photos like these, but I have no idea how to do them.
I would greatly appreciate if someone could explain how these photos are done because they are so beautiful. :
Here is another one with color:

These Pics are overexposed, and in post-production contrast is added (via Lightroom, Photoshop, GIMP - whatever you want.) Also, there is a lot of white (background) space (e.g. the sky), which also emphasizes the contrast. If you want to go about making such pictures on your own, I'd suggest shooting the pictures exposed normally, and doing the over-exposure using Lightroom.
Notice the blown highlights, and in the top example at least, the clipped shadow detail.
This indicates the contrast was increased to the point that both the dark and light ends, but particularly the light end, was clipped.
It helps to start with subjects that have large light areas that you actually want to have clipped to full white. Examples are the table in the top picture and the sky in the second pitcture.
Basically this is partly chosing or creating the right scene, but mostly about post-processing with high contrast.
For example, here is a "normal" view of a picture with a large light area:
I got this by mapping the dark to light range from -.2 to 15, so the visible 0-1 is a small range near the low end. Another way of saying this is that the contrast was greatly increased with substantial clipping of the highlights and a little clipping of the dark end of the ranage:
By the way, high contrast and showing the light parts of the range instead of the dark parts yeilds a totally different picture:
Again, this is all done with post-processing. All it takes is the raw data with good dynamic range.
