I wanted to know if I should invest in a lighter meter with a 1 degree spot meter or will a 5 degree spot meter do just fine? I'm planning to purchase the Sekonic L-478DR or the L-758cine depending on what feed back I get through this community. I'm new to this field of work and currently a student so I want something for long term and I don't want to be in a situation where I need to purchase a 1% spot meter. Thanks.
