I was sure I’d misread the description when I first found these amazing drawings by Samuel Silva. How could they not be photos? Believe it or not, these colorful, photo-realistic images were created using ballpoint pens or graphite and charcoal. What’s the secret to the amazing resemblance to photographs? Huge amounts of time and incredible attention to detail. For example, Silva’s portrait of the red haired girl was created using only seven pens but it took him more than 30 hours to complete.
