There is new firmware out for your HERO3+ cameras. I'm going to expand on some of the new HERO3+ Black Edition features related to Protune:
- New advanced Protune™ controls for Color, ISO Limit, Sharpness and Exposure
- Changes the Protune default settings for Color to "GoPro Color" and Sharpness to "High"
Protune HistoryProtune was originally introduced in a firmware update to HERO2, and it was developed to solve the need of professionals already using GoPro cameras in feature film and TV projects. Protune added a range of modes previously unavailable in any POV camera system: 24p, log encoding, H.264 long GOP at 35+Mb/s. See my first introduction of Protune at NAB 2012 -- this video was six months before its release.
Here is my October 2012 blog entry discussing the HERO2 Protune availability, just weeks before the HERO3 launch.
With the HERO3 Black Edition, Protune was included from day one. There were some small changes: 24p was now a standard video mode (no longer requiring Protune to be active), and white balance controls where now offered including CAMRAW. Protune White balance controls for HERO3 and HERO3+ are:
- AUTO - Same as in the standard modes
- 3000K - Locked white balance for indoor warm lighting with an sRGB color space
- 5500K - Locked white balance for sun conditions with an sRGB color space
- 6500K - Locked white balance for daylight overcast conditions with an sRGB color space
- CAMRAW - Lock white balance with sensor native color space.
CAMRAW is the only non-obvious addition, it doesn't attempt to saturate the image to the reduced color gamut, but standard, sRGB. Shooting in CAMRAW improves the ability to cut GoPro footage with larger cinema cameras, but it requires more post color correction -- except within GoPro Studio which handles the color matrix required automatically.
My shooting tip: I always shoot Protune CAMRAW. The subtler color image is nice to start color correction upon, but CAMRAW is also lower noise. To saturate any image the difference in color channels is gained-up, blue channel noise is crossed into green and red channels, and vise-versa. This happens in all cameras, and it happens in post saturation, but with CAMRAW it is under your control.
The New Protune
Protune within the new firmware on the HERO3+ Black Edition has changed again. The original Protune was the "pro", "tune" that GoPro designed for all professionals, yet you don't have all the same needs. Now it is the mode for pros to tune their GoPro cameras.
Note: The new Protune defaults are very different to previous releases.
The EV compensation ranges from -2EV to +2EV stops of compensation, defaulting at zero. I like to use -0.5 as my default, ready for anything, but I have used -1.0EV or -1.5EV for stage events.
|Here is Protune 2.0 using the default settings, a 1:1 pixel crop from a 1920x1080 image. No color correction applied. Image is nice, but we can do more.|
|Here is CAMRAW with sharpening at Medium and EV at -0.5. The color of the petals no longer clipping, under magic hour sunlight (EV -0.5 and CAMRAW helped.)|
My Favorite Configuration for HERO3+BEWhile I've listed some of my favorite settings above, here are defaults for all my HERO3+ Black Edition cameras (one is not enough):
- Video 2.7Kp30 (24p for night events or creative projects) with a Medium FOV (this mode is the sharpest with highest resolution for video presentation, with very little lens curvature.) For aerial video I use 1080p60 Medium FOV (low light off.)
- Photo Burst 5/1 at 12MPixels
- Timelapse -- I don't use time-lapse photo, I use 2.7Kp24 or 1440p24 video modes and compute my timelapses is post (a GoPro Studio feature.) See Rethinking Time-lapse
- Protune On
- FLAT - Log curve
- ISO Limit 400 or 1600 as needed.
- Sharpness Medium
- EV -0.5 (or downward as needed)
- Sound/Beeps OFF
- Auto shutdown after 120 seconds of inactivity.

GoPro App (Android and iOS)These new Protune controls are all available through the latest GoPro App (free.) An added bonus: within the latest GoPro App (version 2.3) will update your HERO3+ camera for you -- no need to update through the web site.
Hint: for updating the camera software via the App. Get the latest app, and connect to the camera as usual. Now the App knows which model you have, and it will contact the server to request any camera software updates. This can take up to 24 hours of connecting to your camera (behavior from iOS and Android differs slightly.)
