I need an extension or app that can take high res screen shots of regions of websites (including stuff below the initial fold, etc) preferably using Google chrome. I own the 15" rmbp. Chrome has tons of these types of website screenshot extensions but none seem to capture at high res. Obviously images will look blurred depending on the site but I still need this functionality. I could just manually take screenshots with the regular OSX ctrl-shift-4 etc which does take high res screenshots but that means I would also have to manually scroll a site and continuously capture then piece them all together. Any suggestions? Thanks.
