What is photo reference?
Reference photos are something most professional artists won't show you. Like magicians that won't tell you their tricks but most of them are using it. What is it you ask? To learn and observe how to draw, paint or sculpt anatomy, perspective, lighting conditions, composition and materials artists in the old ages used to work with models who posed for them for hours. In the modern age of photography you can save time and simply make a photo or purchase it online. I have a comprehensive store with reference packs for all kinds of purposes.
