Panasonic GH6 Underwater Settings

Panasonic GH6 Underwater Settings

The Panasonic GH6 micro four thirds mirrorless camera is an exciting update to the extremely popular Pansonic GH5 and the GH5s. For a while the GH5 was the most popular underwater video camera on the market. With an influx of new Panasonic GH6 housings, it's a great option for people looking for an underwater video camera with an incredible specs sheet including 4K/120p and 5.7K/60p video recording. The Panasonic GH6 accepts micro four lenses which means there are lots of great affordable underwater lens options including the Olympus 60mm macro, the Olympus 7-14mm wide angle, and the Panasonic 8mm fisheye lens.

But most importantly, the Panasonic GH6 is designed unlike any camera from compete brands with ergonomics that really reflect a video shooter's needs. With so many buttons, dials, and switches it can be a daunting camera to wrap your head around. This guide to the best Panasonic GH6 settings will help you get started taking underwater video and point out the most important features to consider as an underwater video (and photo) shooter.

Panasonic GH6 Dials, Buttons, and Joysticks

The Panasonic GH6 is a unique masterpiece of buttons, dials, and switches. The body is designed to be as ergonomic as possible for shooting topside video, but it can be a little confusing to use in an underwater housing. The menu system, however, is quite easy to use and navigate. The camera itself is equipped with a front and rear dial for controlling shutter speed and apetures. Adjacent to the rear dial, three buttons are very useful for video shooters - ISO, white balance, and exposure compensation. I found it very easy to use the white balance buttons to set a manual white balance underwater rather than going into the Q menu.

Speaking of the Q menu, the "Q" button on the back of the camera should be the button you press the most. It represents a menu of your most important underwater settings on the GH6 that you need quick access to. This menu can be customized, as we will disucss below.

Recording a video is very easy on the GH6. There is a bright red record button on the top of the camera and on the front of the camera next to the lens release. When you are in movie mode, you can also use the shutter button to start and stop recording - which is what we often did.

On the top left of the camera, adjacent to the EVF, there is a lock switch which allows you to lock in your settings while you are filming. What settings are locked can be customized by hitting your menu button -> blue gear menu -> operation panel 1 -> Lock lever setting.

On the right side of the EVF, there is a focus button and switch. This allows you to switch from manual focus to single autofocus to continuous autofocus. If you press the button in the center of the switch you can set your AF area mode or you can zoom into your focus area if you are in manual focus mode.

The disp. button on the bottom right of the back panel is a display button that allows you to flip through different layouts on your LCD.

For the photographers out there, your drive mode (i.e., burst shooting mode) can be changed with the drive dial on the top left of the camera. This dial also allows you to set timers when you are taking photos.

Finally, the joystick under the AF-ON button is used to move your focus points. Some housings may not have compatibility with the joystick which can make AF point selection more difficult. Feel free to contact us to find out if any controls are not compatible with the housing that you are looking at.

Breaking Down the Mode Dial

The mode dial on the GH6 is a little more photo-oriented than we would have liked to see. That being said, there are plenty of options for customization. The C1-C4 modes on the dial allow you to register a custom setting in the menu that can be quickly accessed by rotating the dial. To register your current settings as a custom mode, hit "menu" -> "blue wrench" -> "setting menu" -> "save to custom mode."

The video icon is your movie mode on the mode dial. We recommend using this mode only when you want to shoot video. In order to switch between manual movie mode, aperture priority movie mode, shutter priority movide mode, and program movie mode, you need to select the "Q" button and the exposure mode will be the top left icon.

M, S, A, P, and iA are photo modes. M allows you to take manual photos. S is shutter priorirty which allows you to set a defined shutter speed and the camera will set the rest of your settings. A is aperture priorirty which allows you to set a defined aperture and the camera will set the rest of your settings. P mode is program mode and A mode is automatic - both allow the camera to set all your exposure settings. Underwater, we recommend you use M for photography and move mode for video.

Considerations for Underwater Housings

The Joystick and AF Point Selection

AF point selection with the GH6 is easy with the joystick or touch screen. Unfortunately, no underwater housings currently have support for the touch screen and some don't have support for the joystick. It's important to assign a custom setting to the AF mode button that allows for autofocus point selection. To do this hit the menu button and go to the blue wrench menu. Then go to -> operation 1 -> Fn button set. Select the focus mode button on the focus switch. Change the setting to select the AF point selector whe you hit the button.

In video mode, sometimes we recommend using the "Full Area" AF area mode, but we found it was not it is not accurate at selecting an AF point in macro situations or situations with low light. For macro shooting, we recommend using the autofocus single mode to lock your focus on your subject before hitting record.

The Q Menu

The Q menu, or "Q" button, is the most important button you are going to be pressing on the GH6. It provides you with a single button access to your most used settings. We don't like the default Q menu settings for photo and video, but thankfully this menu is easily customizeable. In fact, there are more options for the Q menu on the GH6 than any camera we have used thus far. To customize the Q menu hit your "menu" button -> blue gear menu -> operations panel (1) -> Q.Menu Settings -> "Item Customize (Photo/Video). We recommend flipping through all your customization options because there are so many. These are our top recommended custom settings that we used in our Q menu, but choose your own based on your workflow.

Important Main Menu Settings

To access the main menu on the GH6, hit the menu/set button on the back panel. The main menu on the GH6 is extensive and loaded with features. Many of these features you won't need to use right off the bat and can be left on default. Of course, some features that we don't talk about in this article might be important from your workflow. So don't shy away from doing a deep dive into the menu when you first get the camera. Here are a few important main menu setting that we think you should consider:

Long Exposure NR should be set to OFF. You can denoise your image in post processing

We leave these three panels in their default settings. However, it's important to note that these settings are still important for every day fnction. In these panels you can set if your camera takes a photo when the focus is locked, if you can half press the shutter to focus, if your shutter button will record in movie mode, and more.

Monitor/Display (Video) (1+2)

V-Log view assist - allows you to apply a LUT while shooting V-Log. A LUT makes V-Log look like it would after color grading while you are recording so you can have an idea what the final video clip will look like. To turn this on, LUT select should be VLog_709 and LUT View Assist (Monitor) should be set to ON if you are using the LCD to view your video.

Setting A Custom White Balance

If you are shooting without video lights underwater, you'll want to set a manual or custom white balance. Setting a manual white balance with the GH6 is easy. To do this, click the white balance button on the top panel of the camera. Then you scroll to the custom white balance setting ("white set 1"). Click the up button on the D-pad and then the "ok" button in the center. This will bring up a box. Line the box up with your grayscale card underwater and click "ok" to set the white balance.
