This is an alternative to the renowned Canon-Log (C-Log) Custom Picture Profile for the Canon EOS-C100 and the C300.
Download CP for Canon C100
The name of the CP explanes as follows: NT NTown, CLOG c-log gamma & c-log matrix, c means color-corrected (n would mean neutral) and a additional capital letter at the end means that the CP is BETA (version A-Z) and the final version does not have this additional ending letter.
USAGE: Extract and copy the .cpf file on a SD Card in the directory structure (create it if it's not on the sdcard) PRIVATEC_PICT import them via Custom Picture Menu: Transfer File -> Load from SD -> (A or B) or just set the CP directly from the SD-Card.
The CP is in it’s test-phase and BETA. But it looks pretty good right now and gives really great vivid colors when graded.
Main difference to the original C-Log is a corrected white balance, a modified color-matrix which gets rid of that slight greenish tone in C-Log and correct black & white levels ranging from 0-100% (unlike original C-log which was ranging from apx. 10-110%).
Skintones will also improve with this CP. They are much more pleasing and nicely showing all color-nuances the face is reflecting.
This CP can be greatly graded with vivid colors and deep shadows. In the video below I pushed the overall saturation to nearly 200% and in addition to that I increased saturation in midtones to apx. 120-140% and the material responds wonderfull the this very intense grading which has pretty deep shadows but retains all the highlights. I used Speedgrade to grade the clips which are recorded with Atomos’ Ninja2 using the DNxHD 220x 10-bit codec which is very clever when interpolating the 8-bit output (or is it more?) of my Canon C100!
When using NTCLOGc The correct exposure for for skintones is around 70%. The exposure is correct if faces and the general image looks brighter than normal. In grading just lower the overall gamma curve to compensate the image brightness distribution against the c-log curve and if you like just add saturation and/or set the tone to you liking.
The tabs below show the difference between the original c-log the the modified NTCLOGc:
I mentioned the problem with the rised black levels and super-whites in an earlier article and think this is a good alternative CP to the existing C-Log Custom Picture Style.
Try it out, test it. Examine it’s skintone behaviour and tell me what you thin about it.
I’m working on a range of new Custom Picture Profiles for the Canon C100/C300 so stay tuned!
This is a growing article. I will update it in the next days/weeks with more info and the new CPs, comparison images, manual settings and more!
