Hello, I am using a Canon 10D with a 24-70mm f/2.8 lens and a canon 500ex flash. I will be attending a wedding in a couple of weeks and I have no idea what exposure settings to use. I am wondering what mode I should work in? Aperture Priority, Shutter Priority ? Could somebody give me a guideline for what shutter speed, aperture, exposure compensation, and flash compensation to use at a wedding ? Also, do any wedding photographers use a filter to warm up or enahnce skin tones and improve appearances? If so, what filter do you use? Thank you, Barret.
