Further to my post of a couple of days ago on author photos, here’s Chris Hamilton-Emery with Salt guidelines, official or otherwise, on 10 Ways to Take a Bad Author Photo.
These tips are invaluable for anyone wanting to have a bad author photo. Such gems as:
If the passport photos are unavailable, wedding photos make great author photos, especially where you feature in the background in a crowd of revellers dancing the conga. Or shots at an office party, where Gwen had her jacquard tights on and you have your arm around her thighs.
But there are plenty more vital, inspirational nuggets of wisdom at the link.
(I should add that the image of me in this post is NOT a photo I submitted to Salt! But I think it's a useful illustration for some sections of the advice.)
