Why Retina screenshots are twice as large as chosen area? This is a known issue, but I do not understand why the screenshot taken on my retina-MBP always has doubled size as compared to area chosen for screenshot:

If I choose 100x100 (as OS shows - of what? pixels? - on "get info" they do not provide, only shows "dimensions") area I get 200x200 which upon scaling becomes more blurry than original picture.

My questions:


Do all retina users always get these doubled screenshots?
How can I take a screenshot of the same size as the area I choose? 


I found a lot of "resizing" solutions, but is there a way to take a screenshot with "original size" without resizing the resultant screenshot?
Yes - that's the way it's coded/engineered
No - you'll need to post process the images using a tool that's designed to automate this or use Automator to make a service to resample the images.


I like Skitch and Napkin for processing retina images, but there are many others.
