Marcello Barenghi is an artist who has posted numerous videos online of himself going through his process. There are videos of him drawing amazingly realistic everyday objects such as a fried egg, a boiled egg, a Pepsi can, a bag of potato chips, a bee, an amethyst, a Granturismo, a Snickers bar, a bottle cap, a rose and more.
Here he draws a lightbulb that looks so real you'd swear you could pick it up. Enjoy!
