Photography is not exact science. It's like painting. The painting maybe a work of art for one and may look trash for another.
Being a photographer myself, here are some ways to choose a photographer:
1) go to his studio and look at his work, his albums. He should have a ton of albums where you can see his style and pattern. If he has one or two albums to show, politely run to the door— means lack of experience.
2) Have an engagement photo shoot. Some studios like roland video and photo give it free. Around 50 to 150 shots will be taken just from the shoot. It will submitted to you and from there, you can decide. If the photographer complaints, go look for another one as he may be complaining too about what he did in your wedding. Translation: he needs more money.
3) See if you photographer loves the work or just in it for your money.
4) try roland video and photo services if you are in the New England area. That should solve the situation.(Ha ha ha)
Good luck to everybody and be happy.
