However in practice, I found the useable ISO range rather limited, especially for photos. The photos can be saved as Adobe DNG RAW, and video footage can be saved in flat profiles such as D-Log and Cine-D. The features a 1/2.3″ CMOS sensor, allowing it to capture 4k video at 30fps (1080p at 120fps for smooth slow-mo), and 12 mega pixel stills. This field of view isn’t quite as wide as a GoPro, but provides a good balance between an immersive perspective with little distortion.
The aircraft will choose the best flight path to return home and senses as far as 300m to avoid obstacles more effectively. If the control signal is lost, the dji drones Pro will retrace its original path to regain its connection after 1-minute. When it reconnects, it will return to home following a straight route.
The phantom 4’s remote control and live feed is based on DJI Lightbridge technology, providing effective control range of up to 3.1mi in unobstructed areas that are free from interference. Its HD live feed gives you an exact view of your flight, perfect for composing shots. Another change involves an updated 3-axis gimbal that cradles the camera on both sides, replacing the single-sided cradle of the Phantom 3. Whether this enhances the stability of video footage or still photographs remains to be seen. It isn’t evident in footage I captured, though admittedly it would be hard to dramatically improve the already silky smooth stabilization the Phantom 3 is known for. Increase operational efficiency by gaining fundamental insights captured by the Phantom 4 RTK.
So when you’ve flown the Phantom 4 to the right spot, your mind can take a break from flying to concentrate on getting the shot. Speaking of which, let’s look at the Phantom 4 for photographers like ourselves. Regarding the controller itself, I found it lightweight, comfortable and robust. Samll things I didn’t like included the rubber battery port cover, which I found too fiddly, and the choice of rubber used for the grip elements, which I can see getting dirty very quickly. The camera and gimble are obviously more fragile, and require a protective guard to be used when transporting the drone.
Due to the highly accurate photo geolocation, the dji drones RTK only needs a few GCPs per project in order to shift the entire model. Technically, we recommend setting three GCPs each time the DJI base station is turned off, reset, or moved. When deployed properly, the DJI base station paired with the Phantom 4 RTK is capable of calculating image geolocation with high precision, but low accuracy.
