Get rid of ugly corner

A friend want to see how I will fix this photo, so here I made this video to show her.

 

This is not a good way to do it, and definitely not the best result you can get. There are millions better ways out there. So It's probably not good to follow this, LOL :)

 

Now you better go check her photo instead. :)

 

ps. caption sync is mess up, and i was too lazy to fix it, sorry :)

Done
