Getting this type of photo of the hummingbird, I used the PocketWizard Flex system to help trigger my Nikon SB-900 and SB-800 flashes using TTL HSS.

I started to shoot this with my Nikon D750, but it wasn’t working. I quickly realized the PocketWizard system wasn’t working with the Nikon D750. That was easy to fix.

I fired up the Macbook Pro, plugged my PocketWizard TT5 and later the mini TT1, and updated the firmware to the latest version.

If you wonder what is up with the green tape, I use it to help me know which channel on the PocketWizard.

I have the small Mini TT1 on the camera with the AC-3. I have A Channel marked Orange, and C Channel marked Green.

The first thing I had to do was update the PocketWizard Utility to the latest 1.58 version.

The website for updating the utility lists all the hardware and the latest firmware. In addition, you can click on the release notes to see what they improved.

Once I downloaded the software, I then had to install it.

Then the PocketWizard Utility alerted me to download the latest firmware. I had the PocketWizard TT5 plugged in, so it knew which firmware I needed.

After the update, the utility shows you a picture of the device you have plugged in with the serial number and gives you all the specs, including the firmware version.

Now I can easily use the system with my Nikon D750, which was newer than the PocketWizards, thus the reason for the need for a firmware upgrade.

PocketWizard’s newest firmware platform taps into the camera’s digital communications to enable a new remote flash capability through our proven radio system. ControlTL allows remote i-TTL for Nikon CLS / i-TTL systems and Manual Power Control. In addition, ControlTL firmware is configurable and upgradeable for “future-proof” continuous improvement.

TIP

Go to all the websites of your camera gear and be sure all your equipment has the latest firmware. If you are unsure how to do this, use Google to search for your camera gear and add the word firmware.
