I dont think EVS or Graham Nolan have any idea how boomer they sound in rejecting all digital tools and assets from comic work. Its the end work that matters. There is no glory in doing art in an antique way that requires maximum effort on things that usually don't matter to the story. Yeah. You can spend several days trying to do a drawing of a car or a helicopter in a background without modeling, without references and strictly I guess based on looking out the window. But what does all that time spent on a background detail in a story contribute to the work as a whole? When you free up time from background detail, you can spend more time getting things like composition or key character art better. Or you can create more art by being more productive.
Comic art in the old days was drawn on bristol board and then inked over because the comics were being printed on four-color letterpress printing equipment mostly used to print newspapers. The world has long ago moved on.
We live in a world of full color printing and digital tools today. Every great artist takes advantage of the technology available to them. They had things like zipatone and lightboxes. They would do polaroid photographs for anatomy references. They maintained massive personal libraries of art reference material to be used in different ways.
There is no difference between using a file cabinet of illustrations and photos for reference then and using 3D assets for reference now. They both serve the same purpose. All that changes is that the technology becomes better and more efficient allowing the artist to do more.
There is also the hypocrisy of Nolan and EVS being such reactionaries on drawing while having no problem hiring colorists who use a full suite of modern digital tools on their art.
Comicsgate had spawned alot of dumb ideas, but EVS's ideas that comic art today has be done with the same technology it was done with 50 years ago is one of the worst.
