Gaffer & Gear 57 - Lighting to Add Colour Render A quick explanation of why to use lights to add colour render in locations lit with very low colour rendering lights, such as overhead industrial fluorescents
Andrew, I’m currently doing the 5 cycles of low-load depletion you advised in episode 4 will Prime a V mount’s chemistry. You also suggested most V mounts have a Watt output that is different to advertised Wh rating and this is often around 150Watt. If you have time, could you please advise how you determine Watt output? Many thanks.
Maximum watt output should be in the instructions or on the manufacturers web site. It is determined by a mixture of things, one is circuitry. The battery should shut off before you overload it in any case.
I like most people never considered the colour spectrum and this is reflected in the fact most RU-vidrs don’t even mention it. Your tutorial reminds me of some video I did in a fluro lit gym a while ago. I didn’t use any of my own lighting and hadn’t changed any settings but the Canon colours were flatter than usual in post. I couldn’t work out what the problem was. Now I suspect it was limited spectrum in the fluro lights. Thanks Andrew.
No the bit debth only affects how many steps of colour are recorded, the recorded spectrum range doesn’t change. Regardless of your Camera you should always use the best Light possible, if you can’t shoot with full spectrum light you should at least shoot a colour chart so you can make the footage a little less horrible in post. And 10 or 12 bit will actually help with that.
Thanks for your advice. I use a colour chart and just moved from an 8bit Canon to the BMPCC6k for the raw and 12 bit. But I don’t have full spectrum lighting yet, only Aputure 120d ii & 300d ii.
Richard Boniface The Apurture COBs are actually quite good, if you look at the Color Spectrum, They don’t have big spikes in the R, G and B Chanel like Flourecent bulbs. Andrew actually did include a Spectrum Graph at minute 39 of his 300d ii review.
You have the right idea in that the camera's sensor also poses a limitation in how it interprets color. This is why the color science is different for each sensor. Some Blackmagic cameras for instance have lots of red pollution which means you need a red filter or IR filter in front of either the lens or image sensor.
