Hello fellow myLotters! When you draw portrait pictures, how do you like your reference pictures? Just today, my brother asked me to draw someone because he's going to give it to that person. Unfortunately, the only pictures available are small. It's difficult to see some details. The picture turned out a good picture but it sort of doesn't look like the person. By the way, did I mention the head on the reference picture would fit in a 1.5 x 1.5 inch square box? It was fun to try my new Staedtler Mars Lumograph graphite pencils but it was frustrating because the picture was so small. For you, what size is adequate enough to be used as a reference picture? How about color? If you're going to draw a portrait using graphite/charcoal, would a picture printed as black&white/monochrome make it much easier to draw it or is a colored picture still much more advantageous? For me, I found using a colored picture better. Thanks for reading and have a nice day!
