Jules, reading started reading Urban Sketching ganz einfach by Antje Linker-Wenzel
I'm just going through the urban sketching books available at my local library. This is not the most exciting one but it's the first that doesn't subscribe to the ableist "you have to sketch on location and never from reference photos or you are not a real urban sketcher" nonsense. She explicitly states that it's cool to take photos and how many people feel much more comfortable working at home. And how she knows not a single person who signed the urban sketcher manifesto because it sucks basically. (Might be a coincidence but it's the first book not written by a man...)
Let's see what else she has to say.
