Upscale images 2x without quality loss.

There are tutorials for this outthere but some are diffuse or go, "you use this here", where you have to figure out through another tutorial where this "here" exactly is.

So, in short, without all the noise or annoying talking floating perfectly manicured heads in corners of video's... here's how to upscale images 2x without quality loss in 5 easy simple steps.

Step1:
Open up Adobe Bridge and select (not double click) the image file you want to double in size w/o adding any (more) artefacts or distortions (PNG doesn't work btw).
(Note this does not IMPROVE an already bad quality image).

Step 2:
Go to 'File' in the top menu and open your selected image with 'Open in Camera Raw...'.

Step 3: 
Go into the side bar/menu and click the 3 'dots' (•••) (More image settings) at the bottom and select 'Enhence...' from the pop-up menu.

Step 4:
Make sure 'Super Resolution' is selected, then hit the 'Enhence' button.

Step 5: 
If you are happy with the result hit the 'More Image Options' button (•••) at the bottom in the corner of the enhenced image and save the image somewhere so you can do with it whatever you like to do now it's twice its original size. 
I suggest not using jpg or any other format that introduces artifacts untill you're ready to upload the file to the web, but hey, you're the boss, boss.
