How does Leonardo da Vinci create realistic works like Lady With an Ermine?

Usually, people would paint both the background and the front of the painting with the same amount of detail. However Leonardo used a technique called sfumato, which meant that he blurred the edges and the background to form a more realistic painting. This technique is also used on Mona Lisa’s face.

i came across this and i found it funny that when you're bored you play hangman on so im going to guess a : )

your word would be isle.

isle is an island or peninsula especially a small one.

if you add the letter "a" you get aisle, which is a passage between 2 rows of something like chairs, shelves, or something else.
