Not to put a damper on things, but I'd recommend reading this first:

Also, just to be very clear, your post reads like your brother is the one who liked the engagement pictures and asked you to shoot the wedding. Weddings are (almost) all about the bride - so, in the interst of maintaining some family harmony, what was your brother's fiancée's input to the request?
Thanks for the article. I'm going to read it this evening.
Both my brother and his fiancé loved the engagement photos. I thought they came out well to. However, knowing the tI am just getting into photography, I am well aware that others could have done a much better job.
To answer your question. Both of them wanted me to do the photography. When asked, I told them that I suggested they hire a professional. They stated they did not have the money to do so and were very happy with the pictures I took of them. I have no problem focusing on being the photographer. I am grateful, however, for the posts pointing out that I will miss out of the moment of the wedding. Since I am going to be the photographer, I want to study up so I can do a good job. Will I do as good as a job as a professional? I don't expect to and know that I will not!! Both my brother and his fiancé are aware of this as I have told them. However, they are happy to have me to do it and now I just need to take the time to do the best that I can for them.
