In the past I've tried different methods from PrintScreen key to Lightshot extension in the browser. Tho, in first way I ended up using image editor to crop, in second - I was limited to browser only.
Since I'm on Win10, lately I use Win+Shift+S shortcut, select the area and image gets saved in Clipboard. If that's enough, I paste it and done. If not - I use PasteIntoFile to create a local image file without any image editor.
Any other methods you would recommend to try, considering quickness, ease of use and image accessibility after the capture?
