As a professional photographer it's almost painful to see someone ask if they should get money for their work. The only reason they want to use your photograph is to promote their products. Therefore your image has value. That value is negotiable depending on how much they want it and how little you are willing to settle for. The industry standard depends on the usage. The more widely the image is used, like in national magazine ads, or internet content, or sales brochures, or point of purchase displays, the more the image is worth. To give you some idea of what companies will pay for images, a friend who shoots International opera stars sells photos of select stars to Rolex for about $7,000 apiece. Rolex will feature the image in magazine ads with their watches. In lieu of payment, an interested party, DJI in this case will hope to get free content in exchange for showing the world your work. That may please you but believe me, even if they were to visibly credit you as the photographer, few will notice. In other words, you'll get nothing in return. The truth is, with so many people offering their work for nothing in exchange for a bit public display, DJI is unlikely to offer you anything; they don't have to. How much should you ask for? Without a conversation regarding the intended usage, it's hard to get anything that will fairly compensate you. At the very least, you could ask for several hundred dollars. Also, DO NOT sign away all rights, and do not give them the raw files. If they want these it means they really want to use your image and they should pay for it. Let me add that it's a beautiful image. Don't give it away to anyone who will make money on it without paying for it.
