Just as we have a tendency to literally judge a book by its cover, we humans subconsciously judge an author, and their work, by their photo. This knowledge is primarily what made me avoid getting head shots taken. Ever. You can’t use Snapchat filters on a professional photograph, I told myself. Anyway, I’m self-publishing, I just won’t include an author photo and bio in my book. Then I remembered marketing is a thing. If I want to post blurry #writerlife selfies on Twitter that’s my business, but if ever want to be considered for a book signing event at Waterstones, I’d likely be needing something a little less casual for their promotional material.
