My 2 cents:
(1) If Photography is your Business
- There is such no free in business. You can always offer him/her good deal/discount/other things like that.
- This is your Bread & Butter. I hope your friend should respect it.
(2) If Photography is your Hobby
- Go! Shoot...its a good experience. That's how I learn from scratch. Free photography just to learn and feel the action.
- And in the end you can use it on your portfolio once you decide going into business w/ photography.
- But of course sana naman he will expect not much because free na nga eh. And no pressure during photo shoot.
