Lighting

For my shooting i want a completely white background and for my night gels and dark background.
To get the completely white background you need 3 lights a big soft box with 2000 DX lamp and 2 small lights faced the background. With the light meter which is set up at ISO 100 and F8 we meter the soft box stating at the same place the we are going to place the model and put it next to the eyer and it always needs to be 5.6. For the other 2 lights the light needs to be 11 and we placed the light meter ate the background. We can turd it up or down from the flash head. For the gels we've got the same lights independents how many gels we want to use we've got the the same numbers of lights and we just place the gels frond of the light.
