photography is a definite MUST! video i think is important too but doesnt have to be professionally done. you will have the pro photos and if you just make a slide show with the pro photos, you will have a gorgeous video like highlight of all
the special moments and details...it's almost the same thing. i think people look at photos more than vidoes. but if you have the budget, can go for it!
we did home video - basically had family/friends do our videos...essentially capture the moments, including getting ready! (my sister took all the shots :P). but beware that the sound quality wont be as good - you can always record over with
music, unless you want the original voices (ie. vow exchange)...we are editing our own footage and putting in our own music. if you got the time and have a nice computer, it's doable...
but if you need the professional feel, then gotta pay for it...it all just depends what is important to you what type of media you like.
