At the start of the year I shot a music video using Technicolor's Cinestyle loaded into a Canon 7D. I graded the video myself in Apple Color using the S-curve display LUT provided by Technicolor here. Instead of using the LUT as a display LUT, I rendered the grade with the LUT applied. The theory is that passing Cinestyle material through this LUT gives you a pretty standard DSLR-like image, but playing with the information in the image upstream of the LUT unlocks more shadow and highlight detail than you could gain access to without shooting Cinestyle. I did this by using the primary out curves.
It did slightly bug me not knowing what the LUT was doing exactly so I took the liberty of extracting the info from the LUT and plotting it myself. I hope it is of help to some.
PS By those alarmed by the 'DR theft' debate, it is unfounded, and you can read why here.
I recently shot the feature Nightmare Box for American director Jon Keeyes, and we had a long candlelight sequence round a table. When the subject of dollying 360º round the table was breached, I started worrying about how to light it all in a convincing fashion. Then I stumbled upon a camera test by David Fincher, filmed on the same camera as the one we would be using, the Red One Mysterium-X. The clip, which is shot at ISO 2000 and lensed with a Master Prime at T1.3, features Leonardo DiCaprio lighting a cigar with a match. The background is lit, but the key on DiCaprio’s face is provided exclusively by the match and cigar.
This clip brought home the total feasibility of using the Red MX with a T1.3 lens to light our scene exclusively with candlelight. After all, ISO 2000 / T1.3 corresponds to a 1.5 footcandle key. Production designer Eric Whitney sourced a large number of candles and very cleverly dug out the top and popped in tea lights, saving me hassle with changing light levels and saving himself hassle with candle height continuity.
We spent the sum total of a full shooting day dollying 360º around this table seating four characters with 10-14 candles (I forget the exact number) as the only light source*. We were able to get hold of MkII superspeeds thanks to Lightning Media in London. This was my first time using their superspeed set and I was astounded by the optical performance wide open – much more solid than other superspeed sets I’ve seen.
Below is an H.264-compressed HD quicktime of our camera test using a crew member as stand-in. Red MX @ ISO 2000 / 24fps 180º / 4500K / Superspeed T1.4**
A slight contrast curve is applied to the above file. For anyone interested, here is a .zip file containing the raw camera file for your scrutiny, as well as full-res TIFFs.
Check out the film when it comes out to see the full sequence!
* At the very end of the sequence a character stands, and I had to carry her with a dedo for that segment, but the rest of the sequence is lit purely by the candlelight.
** Although this test is 24 @ 180º, the actual scene was shot with a 225º shutter, i.e. 1/40th @ 25fps. We went to 25fps one day into the shoot for flicker reasons, and I opened the shutter on this scene to help the exposure out.
