I posted this in another forum but I need all the advice I can get so here it is: I am not really in business yet. I start a FB page in the fall advertising and also did a craigslist ad. THEN I realized how much I still need to learn about photography so I left up the FB but stop trying to advertise. I totally forgot about the craigslist ad until I got a phone call yesterday. So a very sweet lady contacted me wanting to know if I could be present at an event she is going to be hosting at her home in March. She said she wasn't looking for professional photos since they would cost too much so I agreed to take the pics. The event is a pre-wedding ceremony for a Muslim type of cultural rituals. She expressed her wanting me to capture the bright colors in their outfits and also all of the ceremony rituals they will be doing. So here's what I have to use, a Rebel T2i, 18-55mm kit lens and 50mm 1.8 prime. I just ordered an extra battery and I have a speed light. Now the ceremony will be in her basement. she says they will have all the lights on and some Christmas lights hanging as well. I have concerns about the lighting and my lenses. I have my big speedlight flash but I honestly have no clue what is the best way to use an external flash like that. I understand natural lighting but haven't gotten to studying about external flashes. Also, I want to be able to use my prime as the kit lens just takes really blah photos. but I'm not sure about adequate space to back up and move around where I need to with a prime. Do you think a 50mm will be ok? what would you use for this type of event? Should I rent a lens?
