If i were in your shoes, i would shoot for him too. But my gf's bro is those that is hard to part his money with. Don't think he will give me good ang pow.
And talking about appreciation, my gf's bro's wife said "thank you" to me without looking at me but looked on the floor instead, when i took their ROM pics for free! :angry:
Palvin,
You are really between a rock and a hard place. Either way, you are screwed. The decision you made should be based on which is the lesser of 2 evils. Bear in mind, I really do not care how you feel about your future brother in law, how you think he is a cheapskate, how you are being taken advantage of. Those are neither of the 2 evils you are facing.
I am making an assumption that you and your gf are in a or going towards a long term relationship. If not, decision is so much easier.
I am also making another assumption that you are not a professional photographer, nor a semi-professional, nor a seasoned wedding photographer.
So, here are your real problems.
You don't shoot.
1) Your gf gets unhappy. She is put on the spot becasue you refused to help.
2) Your future father and mother in laws get unhappy. (you brother in law's feeling does not count.)
You shoot.
1) Your pictures came out ok, nothing great, and all your future in laws start complaining. (My assumption is your pictures won't be good because you don't want to shoot and you are not experienced)
2) Your gf is put on the spot because your pictures were not masterpieces.
If you shoot, there will be one more downside. Other relatives will be asking. And you won't be able to charge them, and even if you can, at slave labor rates.
I don't know what you will do. I know what I will do. I never say no to any request for a shoot of anything, but I will always charge expenses. No exception. And I quote extremely high expenses, which scares away everyone, except one, and man, that was a tough experience. So, I triple my expenses since then. No one ask me to shoot things I don't like to shoot any more.
I won't shoot. Simple. I would tell him straight up, that I never shoot if my expenses not covered. What's your excuses? You have to think of one. Be honest, but a white lie sometimes makes things easier to swallow.
