Ive spent some time working on custom picture profiles for the Canon C100 and Canon C300 cameras that allow both cameras to be cut together and match well. I don’t own test charts but I’ve tested these under various conditions and they match well. The following examples were shot using the built in tungsten setting on both cameras, manual white balancing or dialling in Kelvin settings on both cameras can produce non balanced results so I prefer to use the presets for two camera shoots when possible.

This is a neutral custom picture that has similar results to having no custom picture at all with the exception that the sharpness is dialled down to -5 on both cameras and the WB levels are tweaked on the C300 so that both cameras produce a similar colour balance.

I developed this custom picture profile mainly for my Harley-Davidson projects but it’s proved useful for a lot more than just event work. Canon Log definitely gives you more dynamic range and options in post but with fast turn around projects I prefer to shoot with a profile that produces more of a baked in cine look. There’s a CINE1 Gamma applied to give a bit more contrast and I’ve used a normal1 colour matrix so that the colours pop a little rather than a CINE matrix which would result in more muted colours.
The images below are obviously not designed to highlight the look of the custom picture, they are more to show how the C100 and C300 profiles match colours. To see what the custom picture looks like have a look at some of my recent videos.

These are based on the standard CINEMA profiles. The Canon Log gamma is used but with the balance corrected to allow both the C100 and C300 to match in terms of colour and levels.


The custom picture files can be downloaded below. Please note that the firmware update 1.0.7.1.0 that has to be installed by Canon changes the way colour is handled on the C300 so there are different versions of the files.
For C300′s with 1.0.6 and earlier - downloaded here - last updated 6-12-2012
For C300′s with 1.0.7 firmware – download here - last updated 12-2-2013
Please come back and let me know how they work out, good or bad any feedback will help to develop the files further.
Installation
This is based on mac, windows should be similar but I don’t have a windows machine so I can’t be sure. Please note that these custom profiles use the first positions on the card, if you have others in those positions that you wish to retain you will need to back them up prior to installing these.
C100
1. With an SD card inserted in the C100 copy one of the standard custom picture profiles from the camera to the SD card using the transfer option with the custom picture menu. This just creates the required folder structure, if you already have custom picture settings on the card then this isn’t required.
2. Eject the card from the camera and mount it on a computer. You will see a main enclosing package called ‘PRIVATE’, right click on that and choose ‘show package contents’.
3. Now you should see a folder named C_PICT, place the C100 picture profiles in that folder and then eject the card.
4. Re-insert the card into the C100, go to the custom picture menu and either select the profiles direct from the SD card or copy them to the camera.
C300
1. With an SD card inserted in the C300 copy one of the standard custom picture profiles from the camera to the SD card using the transfer option with the custom picture menu. This just creates the required folder structure, if you already have custom picture settings on the card then this isn’t required.
2. Eject the card from the camera and mount it on a computer. You will see a main enclosing folder called ‘PRIVATE’, open that folder.
3. Now you should see a sub folder named C_PICT, place the C300 picture profiles in that folder and then eject the card.
4. Re-insert the card into the C300, go to the custom picture menu and either select the profiles direct from the SD card or copy them to the camera.
