DJI Go 4: How to use AE bracketing to get the best aerial photos
How to make HDR from your aerial photos.
Tips for Quadcopter Owners
What is Auto Exposure Bracketing (AEB)?
Any camera sensor has a limited dynamic range, which means it can only capture details of limited brightness. Exposure is set at the time of shooting to the middle of this range, and details that are brighter or darker than the center of the range are also captured.
Auto exposure is convenient, but when shooting high-contrast scenes, you can get embossed areas or vice versa completely black. These parts of the image at the edges of the dynamic range can be very difficult to recover in post-processing. This is where bracketing comes in handy. Auto exposure bracketing allows you to take multiple shots in a row with different exposure settings. When you select the AEB function in the DJI GO 4 settings, your aircraft will take 3–5 photos at different exposures. Thus, additional frames will give more information at the edges of the range and significantly expand it.
Shooting using bracketing is necessary for at least 2 reasons. Firstly, this compensates for the imperfection of the smartphone screen, which can deceive you when choosing an exposure in bright sunlight, in the shade, and can also be distorted by the screen brightness settings and a host of other factors that can prevent you from correctly assessing the situation and setting the parameters. When shooting with AEB turned on, you have insurance in case of a mistake in the settings. The second reason to use AEB is the ability to create high dynamic range (HDR) images. These photos can be obtained by combining several frames with different exposures.
How to Create an HDR Image in Photoshop
In this quick HDR photo tutorial, we will use 3 images taken at different exposures in Vietnam — Ha Long Bay.
1. Open Photoshop, then menu File > Automate > Merge to HDR Pro. In the window that opens, select the photos you want to merge. Select “Select to automatically align source images” to avoid ghosting or ghosting.
2. Photoshop will automatically combine the images and assemble them into an HDR photo.
3. Saving the image in 32-bit format will give you the opportunity to use the full range of tools available in Adobe Camera Raw without losing image quality.
Whether you’re composing HDR photos from multiple images, or just using AEB to capture the right exposure, DJI Go always delivers the best shot.
