Be professional. When you submit a résumé, don’t type it in ALL CAPS and please don’t avoid the caps lock like the plague. Know how to use it without looking incompetent. Write in complete sentences with proper grammar. Of course, there will be exceptions, but even with the exceptions, you must keep it professional. You’re building their view of you.
Disagree with the photography idea. It may seem easy but there are those of us who have spent, in my case 10 + years learning the light, the technical aspects, the right way to pose… we have to keep pushing our prices higher because there are more people starting to eat away at the client base by undercutting…. and we’re trying to make money and feed families too. It only hurts an industry to undercut. Sorry. Good list otherwise, don’t do it as an expense to others.
