Realist artists paint a true representation of everyday life in a naturalistic setting. Realism is about depicting the truth as the artist sees it. Real life, real people. No idealism or exaggeration.
As a style, realism doesn't adhere to classical rules.
Instead, artists paint what they see, often using everyday observations as their
subjects. It attempts to represent the subject in a truthful manner and
without any artificiality and usually avoids anything that is implausible.
The difference is when you draw by memory you won't remember every tiny detail, and you make/draw it in your own way vs. having the object in front of you you can copy it almost exactly.
