If you can provide basic suggestions such as:
- Mode - Full, CA, P, Tv, Av, or M?
- Flash or not? Fill indoors, outdoors, etc.
- ISO on Auto from 100-800 or just set it on a particular value?
Just really a comprehensive review of the basics for a guy trying to do the best he can.
awww man...if you're asking these questions, then you need to review the basics about ISO, Aperture, and shutter speed. i know you're going to come back and say I REALLY UNDERSTAND IT, but do you?
you didnt tell us how much time you have before the wedding. BUT, for your own sake and for your own learning experience, get away from this computer and take your camera. Set it to MANUAL and start shooting. Teach yourself how to adjust ISO, Aperture and Shutter Speed until you have the best exposed picture (learn to read your histogram).
Ask yourself -
Are the pictures exposed correctly (not too dark, not too light - see what your histogram)?
What's the relationship between ISO, Aperture and shutter speed?
What's the values for ISO i need to set for indoors and outdoors?
What're the correct white balances i need for indoors and outdoors?
From then, you'll find using Program mode and Aperture mode more helpful. After that spot metering, AF lock, flash (ETTL and then manual). I do weddings every
weekend, all this is second nature to me.
But serious, if you're photos are just dark or just over exposed, have no clue how to fix it, and pissing your pants, just set it to AUTO. And please, look down and see what you're taking. Don't take a 100 photos in a row and not look at your screen.
Good luck, hope you can do well.
ps. anyone can tell you to get this lens or that lens. or i can even lend out my equipment to you, but i guarantee you, it won't make a difference compare to your 7D. 7D and 24-70mm is good enough for a second photographer. learn your basics is a must.
