am I being unreasonable? (long vent)

Ok , so here is the plan. Right after the wedding the bridal party will be going to the Long Island Museums in Stony Brook to take pictures for about an hour. Then head to the reception hall where we will take family pictures on the golf course, simple, easy.....OK, so now my mother is all concerned that the family pictures are going to be...oh, wait for it............too GREEN, yes, I said too green, as in too much grass and greenery, she thinks it will look stupid. She says 'I don't want to pay all this money and have our pictures look like crap.' First off, I should've have mentioned from the get go our photographer is Angelica Glass,so there is no way the pics are going to look horrible. I was like, MOM< I dont want a million people at one site taking pics all at once, it will be too much...I was finally like, whatever, come if you want, but I think that just made her upset, she didn't say anything else. Am I wrong? Why can't people just do what I ask? Now I know why they start filming Bridezillas a week before the wedding, cause I am definetley one right now.
