Happily for you having 7d may help you with flash setting. Having 430 and 7d you can experiment with flash off the camera's shoe and using it a slave mastered form 7d's built in flash. You can simply find more convenient place for flash operating than on a camera. Built in flash usually tends to cast shadows and it depends usual on a distance from people to the rear wall. This configuration (7d + 430) is really nice o experiment with. If you decide to use this technique (built in flash for master and 430 for slave) you have the opportunity to use 430 as a source for ambient light (directing it on a wall or ceiling if they are white). Experimenting with proportions of light (inbuilt vs 430) you can avoid shadows but rather make people having small light reflections in eyes and not overexpose then from front. I would set proportions of lights in such a group to 4:1 or even 8:1 (430 vs built in flash). If it's difficult to cast light on ceiling on a wall (they are not white or ceiling is high or walls away like in church ) you could experiment even more trying to put your slave 430 on a chair and cover it (letting some room between then) with white tshirt or sheet. This will let you feel like having a softbox still with master in your inbuilt flash.thanks everyone for your feedback.
I tried some shots last night.. couple questions.
1) when I shoot in auto mode... 1/60 F 4.0 ISO 1600 is the configuration shows up for the pictures .. when I set everything in Manual with exact same settings... the exposure indicator is around -3... which is not good...
When I lower the speed for the the correct exposure to 0 the speed is around 1/15 too slow... and pictures are over exposed... if I lower the ISO i have to further reduce the speed...
The pictures look just fine in auto mode or in M with the settings mentioned above.... so what is wrong with the exposure?
when we use flash (430) on camera do we still try to get correct exposure?
Nothing is wrong with the exposure.
Definitely bounce the flash off the ceiling...but hopefully the ceiling is white, else you end up with a color cast in the shot. If the ceiling is colored, head to a craft store for a large piece of white foam core, and have someone stand on a stool behind you and hold it over you at an angle, pointing the flash head up and back to bounce the light off the board (you'll have to play with the angles to get the positioning correct).
