Grayscales

[peter_g]

Hello everyone,
When I was in filmschool we used to shoot greyscales for the lab. I think they allow the lab technician to match the scenes when making prints/telecine'ing, but I'm quite unsure of this and would appreciate if someone could clarify it. Also, we shot on black and white film - would some other type of chart be shot at the start of each can of colour film?
Thank you all

Grey-Cards are for both B&W and color. You want to shoot one whenever there are major lighting changes on a roll. I like to give one to the clapper so that there is one on every take. You can also use a chip-chart but they cost more than a grey-card and I don't think they give better results...

Good luck
