Measuring Light Output
Jacob Mitchell posted a topic in LightingHi All! As a student, each projects means a way to stretch myself further. If I'm not trying something new (or a little bit scared) on a project then I feel like I'm not taking steps forward. Lately I've been doing pretty in-depth floor plans and 2D pre-vis, and it has been working wonders for every project. However, I'm still working to get exactly what I want in my head to paper, so that on set my images are not a surprise. Is there a way I can tell how many foot-candles a certain light will output? I'm wanting to essentially know exactly how powerful a light I'll need to expose to a pre-determined f-stop. I'm familiarizing myself with inverse square law, so all I'd need is an output at any one distance and could work from there. Is this just a knowledge gained from experience? Or is there a practical way to determine output? Thanks, Jake Mitchell
I was wondering how does one transition from the learning phases of practicing lighting scenes with what you can afford ( basic tungstens, DIY Grip gear, consumer bulbs and other stuff) to being able to plan scenes confidently without those limitations. Do you know that your daylight gymnasium scene will need 12k HMI's to get those shafts of light the way you want because of 1st hand experience? deferring to a gaffer? educated guess? photometric calculations? The same question would also apply to camera packages. Do you ever recommend to a director a camera package you haven't used before? what was the basis of that decision?
