1.Lets begin with an anime picture.I chose this :

Spoiler:

2.Now select the pen tool.

Spoiler:

3.Now time to zoom the picture.see at the bottom left something like x% should be there (where x = some constant).When you find it just increase it to 500% and The picture will get automatically zoomed.

Spoiler:

4.Now make selection with the pen tool along the border of the character of which you want to make the render.When you finished selecting the whole thing (make sure the end point of the selection meets the starting point) press right click on the image and select 'make selection' and write in the feather radius '5' and press ok.

Spoiler:

5.now press ctrl + shift + i (this would invert the selection) and push delete and then 'ok'.
your render is ready just erase some parts if it feels necessary and you would have a perfect render.We could have had used the magic wand tool but the pen tool is much better than it.
