Hi! My name is Andreas, and this is my first post in this forum!
I am also new in cinematography and was hoping someone could help me with this question regarding white balance best practises:
I am shooting a relatively long ceremony in a church (approximately 2 hours) - it is a combines baptism + wedding taking place right before sunset. The natural light coming in will probably change quite dramatically during the ceremony - both in colour as well as in quantity - and possibly by the end they will turn on the church's lights too.
So far I have been relatively lucky film ceremonies taking place much earlier in the day when light would be consistent throughout. I would set the camera whitebalance setting to Kelvin and would make an approximation using the screen. I fear that with my next event this method will not work very well and I might end up with clips that have varied whitebalances and will give me trouble in post, as I will probably struggle to get consistent colours.
Shoot indoor on 3200 and outdoor on 5600. If you take use AWB or change the settings while shooting you will be chasing color in post. Shoot a white / black / gray card throughout the day... or just a gray card. This will help with the 3 way color corrector. When shooting weddings the bride is the white card and the groom is the black card.
