How to Adjust Your Camera’s Manual Settings in the DJI GO App

Since all of my tips involve manually adjusting the settings of your camera, it’s important to first understand how to do this in your DJI GO App. You can get more in-depth instructions from DroneDeploy’s support documentation, but here’s a basic overview:

Use Your Histogram to Adjust Shutter Speed

Set Your ISO at 100 for Crisp Images

Remember the old days of photography, before the digital era, when you had to buy camera films of different speeds? ISO is the digital equivalent. It indicates the level of sensitivity of your camera to available light. In automatic mode, DroneDeploy will select a fast enough shutter speed to avoid motion blur — to do this, however, it may have to bump up the ISO. The problem is, if the ISO increases too much, you run the risk of excess “noise” in your images. In other words, you’ll lose some of the detail and get that overly pixelated — or grainy — look. DroneDeploy’s automatic settings already do a good job of managing the balance between the shutter speed and the ISO, but if you want to bump up the quality of your images even further, I suggest setting your ISO manually.

Customize White Balance for a Consistent Map

Finally, I’d suggest customizing the white balance of your images. The white balance is the temperature of the image — how much yellow or blue cast is present. In the automatic settings, your camera will adjust the white balance continuously throughout the course of a map, making an individual decision for each photograph. For mapping, because consistency across all of your images is so important, I’ve found it’s best to set the white balance beforehand and keep it there for the duration.

Take the Next Step: Learn More About Photography and Post Processing

Congratulations! You’ve graduated from automatic mode and taken the plunge into your camera’s manual settings. I think you’ll find these three steps make a difference in your image quality, but I also highly recommend any commercial drone operator invest the time to take an introductory photography class. You don’t need anything fancy. A fundamental photography class, a few hours a week for a month or so is a great way to get a handle on the basics.

Use Adobe Lightroom and other post-processing tools to further improve your images
