If you decide to use a pseudonym for your writing, do you wear a disguise for your author photo?
Do you color your hair and eyebrows?
Do you hire a makeup artist to transform you into someone you aren't?
Do you part your hair on the other side and wear different glasses or none at all?
Is it wrong to hire someone prettier and maybe younger or just more professional-looking to pretend to be you for the picture and maybe events (should it come to that)?
Or maybe the photographer can alter the photo enough to remove freckles, add a tan, wipe out wrinkles, stretch it out to fix that weight issue, recolor the hair, and flip it to a mirror image to take care of that part? That would probably be better.
(BTW, I say 'you' - but I mean me. I'm sure none of you have any of these insecurities.)
