Transitioning to Digital Agencies Needs

How can an artists drawing abilities help out Art and Creative Directors in their pursuit of effective Digital Advertising? In my opinion, being able to quickly convey ideas in a digital format regardless of the content is key to helping art directors develop their ideas. Just using photos from Google limits the creative process to what other creatives have already  done. Using an artist to help doodle your NEW concepts helps spark quick new possibilities that photos do not. When all the information is given to you, in a photograph, you are less likely to interpret the information in a new light. To me it is very important to let each individuals mind finish the process. Do you agree?
