You're probably never going to have more pictures taken of you in a single day than on your wedding day, so it's important to be prepared. After all, one of them could end up on the mantle. Here’s what I suggest to help make sure at least a few photos turn out great:
1. Get to work.
Start preparing your physique for the big day a few months in advance. Remember that pre-spring break beach body regimen from college? Well, this is your new "spring break", so dust off those sneakers and convince yourself kale isn't as awful as it actually is. And if that's too hard, at least avoid bloating (dairy, legumes, etc.) and salty foods for a few days before the wedding.
2. Don't wear your bachelor party on your sleeve.
Bachelor parties are a must—don't let anyone tell you otherwise. However, be smart and have it a month before the wedding instead of the week or night before. The best places to get married are not the best places to have your stag night (case in point: Vegas), and looking hungover and bloated from the cheese fries you thought were a good idea at 3 a.m. never translates into a good shot.
3. When it comes to hair, take the long view.
As far as grooming goes, be smart about how trendy and edgy you want to look, and remember that what's cool today might make you cringe every time you see it in ten years. For example, my uncle and his groomsmen sported mullets when he got hitched in the early nineties. Needless to say, his wedding photos are hidden in a box in the attic. Keep your hair and facial hair as classic as your tux and your photos will stand the test of time.
4. Take one for the team.
Smile a lot and make good eye contact with the camera, even if you hate having your picture taken. Whether you like it or not, every camera will be pointed at you, and you don't want the pictures to show you with your eyes closed, mouth open, in the midst of explaining that you don't like pictures.
5. Identify your "good side".
If you really want to get serious about it, find your angle. Everyone has a certain angle that looks slightly better, and this is usually due to our natural asymmetries. Ask a friend to take a couple of pictures of you at different angles and figure out which you like the best.
