I had the opportunity to work with DP Brian Weed during our Cine Gear 2012 coverage. Brian operated the FS100 that we shot all our interviews with, and he did a great job. Recently, Brian shared some excellent CP picture profiles for the Canon C300. He’s taken the stock Canon CINE, LOG, and EOS STD picture settings, and tweaked them to better retain color.

The result are image settings for the C300 that accomplish much of what the stock picture profiles do (very good things like low contrast and good highlight retention in the case of the CINE and LOG profiles), but with an improved color palette that requires less massaging in the color grading process. Brian has dubbed these TRUvid2, TRUcine, and TRUlog. He posted a couple examples in a gallery here, and he’s given us permission to host an archive of the three profiles in a zip archive here. If you wish to give them a try, here’s how you load them onto a C300:

* Download and extract the .CPF files.
* Copy to a SD card that has been freshly formatted in the C300. CPF files go into the C_PICT folder, which is under the master private folder. (You’ll see this directory structure after you format the SD card in the C300 and plug it into your computer…if you don’t see it, you can manually create the folder structure).
* Insert the SD card into the camera, and either use the CP’s directly from the SD card, or copy them onto your camera under the OTHERS menu.

I recently shot a spot with director Jesse Rosten on location in Mexico. It was a doco-style commercial shot on the C300, and after some testing we decided on using Brian’s TRUlog CP for everything. It worked great. I really like the look of it, and I’ll likely use that profile again in the future. After we wrapped the shoot, I took a few minutes to shoot some quick & dirty comparison frames with a color chart, so you can quickly see how the different settings affect the image on the C300. I’m embedding a short video clip of those frames below. Since this is hosted on Vimeo and has been compressed, please consider it only a rough comparison of how the colors differ for each setting. You can also download the original source files (531MB), if you wish to view them at original quality and push and pull on them a bit in your grading tool of choice.

Technical notes:
These DSC Labs Chroma Du Monde 28 color chart frames were all shot on the same lens (a Contax 50/1.4) at the C300’s baseline 850 ISO setting and 180-degree shutter. The chart was lit with a daylight-balanced fluorescent soft light, the camera was set to the Daylight white balance preset, and the light level on the chart remained constant throughout the test. The stop on the lens varied from f/4 to a f/5.6-f/8 split, as each color profile significantly affects how the camera responds to light. I exposed “to the right” in all cases, pushing the highlights up to their max level, just below clipping on a 100% zebra. This is not necessarily the only way to test these profiles, but works reasonably well for my purposes assuming a somewhat uncontrolled shooting environment. For more reading, Adam Wilt has some standard gamma comparisons done a little differently here. I have also included quick-n-dirty snapshots of the C300’s waveform display for each chart frame, to show roughly where each CP sits on the scale. The original source files linked above are XF files straight off the C300 CF card. The Vimeo video was output by Compressor, and originated from ProRes 422 files created via FCP7 Log & Transfer of the original source files.
