macbook promacosscreen capture
So I take a screenshot of an area with Command+Shift+4 but when I open the screenshot file in Paint X, the image's dimensions are far larger than the original area.
Is there any way to take a screenshot that looks exactly like the taken part of the screen?
As far as I'm aware, there is no way to manipulate the system crosshair picker, however, Skitch (free!) offers an alternative workflow for partial screenshots. They have a zoomed preview dialog, and the fully extended arms as you desire. Also free in the Mac App Store.
Open Terminal and type the command below. From there you have 10 seconds before the screenshot is taken (you can do whatever you want or hold any keys you want in that time).
Afterwards, you can find the screenshot in the directory you executed the command.

Screenshots taken on a Retina display will be twice the size as screenshots taken on a non-Retina display.
Most software such as Preview will compensate for this, however I'm unfamiliar with Paint X and doubt it is correctly showing the image rather than the image being 'wrong'. Try using software optimised for a Retina display.
If you want take screenshots for non-Retina displays, you can use RetinaCapture. Note that these screenshots at 100% on Retina displays in software optimised for Retina will be smaller than real size.
