What is DJI MAVIC 3:
The new DJI Mavic 3 drone takes design elements from the phantom series and inspire series with a H frame design for increased stability, speed, and accuracy.
DJI may be building the best features from their various drones into one awesome drone platform.
This is a drone with an interchangeable camera that makes it easier to take photos in specific exposures.
Imagine a drone with the flying capability of the inspire 2, matched with the mapping capability of phantom 4 pros combined with the color gamut of a Hasselblad sensor on the Mavic 2.
DJI Mavic 3 design:
Now they are coming with a new folding design. This folding design would allow for the arms to fold over the center frame of the aircraft. This would also make the center of gravity very low as well. With a lowered CG, we can expect an aircraft to have increased stability and maneuverability. DJI has steadily increased stability in the Mavic series by offering folding props and cantered motors.
The inspire 2 and inspire 1 aircraft offers increased maneuverability and stability due to the H frame build of the aircraft. DJI's new patent indicates this H frame design may be evident in the new Mavic 3. Yet, the H frame design is not a design we have seen before.
Magnet-Enable Landing System Patent:
DJI has designed drone docking technology that uses magnets to help a drone land in a specific location.
Magnet-enable docking technology would not just help the drone land in a specific spot, but could also help it hover above that location.
Docking is a big concern for drone delivery, especially in urban areas where there is no margin for errors when it comes to where you land.
DJI Mavic 3 release date:
Following the release of DJI Mavic Air 2, a lot of drone lovers started carrying rumors about the upcoming DJI Mavic 3 release date. That's no surprise because, as with the smartphone industry, the drone industry is very important.
If the rumor is anything to go by, we should expect the DJI Mavic 3 to drop by the end of this year. But when exactly should we be expecting it?
Although there is no official word yet, we have seen a lot of suggestions lately. While some suggested we should expect it in summer. Since we did not see it in January. We will have to wait and see what will happen between June and September.
Folks at Drone XL have learned from a reliable source that DJI is planning to unveil the Mavic 3 on September 26th. The unveiling event would take place at 10 AM, EST. Notably, September 26th falls on a Saturday which is unusual for DJI. But considering it will be an online event, DJI could get a bigger audience to attend the launch event on Saturday.
According to Drone-DJ, the Chinese company was planning to release three drones in 2020-the Mavic Air 2, the Mavic 3, and the Matric 300.
DroneDJ has a source which said that the company has decided not to release the DJI Mavic 3 in 2020 because the Mavic 2 continues to fly off the shelves. It makes little sense for a company to bring a successor when the older model is still selling like a hotcake. However, the company can change its plans any time depending on market competition.
If you want to become a professional photographer, one thing you must have a neutral density filter. But most of the people don't understand all features and how, where, when to use them to take their photography skills to the next level.
Neutral density filters put emotions in your photography. And there are also certain problems for beginners in how to use them because manufacturers seem to vary in their preferences in making ND filters that confuse photographers. In this article we will talk about ND filters and when you should use it?
What is a Neutral Density filter?
The ND filter is a filter is placed on top of the lens to reduce the amount of light making its way into the camera. Think of the ND filter as sunglasses for your camera that do not change the color of light being captured by the camera and lens-hence the “neutral” nomenclature.
Why do you use ND filters?
Suppose you are taking the picture of a lighthouse, your camera setting could be something like this; ISO 100, SHUTTER speed 1/1000 second, an aperture of f/8.
Picture may look good but there are some distractions in the background due to waves.
We want a smooth and eye-catching view, so we will use a long exposure.
A long exposure records the scene over seconds, stopping our camera from freezing the movement of the water.
We need a shutter speed of 15 (seconds) so we change the shutter speed on our camera. Except now, we have added 14 stops of light into our scene. So it's now just a white, black image.
The ISO is at its lowest, so that won't help, the shutter speed will go from f/8 to f/11,f/11 to f/16,f/16 to f/22. There should be only three stops until we reach a maximum.
So what about the other 11 stops?
Here is where we use of ND filter. We need a 10 stop ND filter because we can't get precisely 11 stops: we will need to deal with extra stop using editor software, and will be able to create a proper exposure.
Some uses of neutral density filters:
In waterfall photography:
Neutral density filters are usually used by photographers to slow down waterfall or blur backgrounds. So if you want to take a picture of smooth and silky water you have to use slow shutter speed. If you are capturing in early in the morning when light tends to become faint, there would be no problem using your lens without a filter.
But when the intensity of light is too much and there is a risk of overexposing, you should use ND filters.
The same goes for taking portrait pictures. There are times when you will want to draw more attention to your subject by blurring out the background. To do that, you need to use a wide aperture. If your camera does not allow you to use a wide aperture
If your camera does not allow you to use a super-fast shutter speed (like 1/1000s) to block out some extra light, you will end up with an image that is too bright.
The neutral density filter blocks out the light from all wavelengths, giving you a darker picture overall.
Why do you need neutral density filters?
Neutral density filters are a must-have for anyone. They are great because they let you have your cake and eat it too. You get rich and colorful skies without making the ground look too dark. I would recommend them to anyone interested in getting better at landscape photography.
Searching and Rescue (SAR):
Drones provide a service of Search and Rescue (SAR) for public safety and are used by different departments in an emergency i.e. Police, Firefighters, etc. For example during natural disasters or in an emergency drones can search for a stuck person during an avalanche
Problems for Rescue Teams:
How can we resolve these problems:
Drones can provide a service to locate people immediately without losing time and having to increase manpower. It also helps to reduce costs and risks of the lives of those people who help rescue the stuck people.
Day and night situations can also have adverse effects for a team. Due to darkness people may be hidden. The rescue team will face a lot of problems to find the victims. This isn't a big problem for drones which can have thermal imaging
Drones can locate the victims through Infrared (IR) thermal imaging cameras because they can search the people through their bodies' heat. Then, after a quick response, we can provide a First Aid or rescue them in that particular area instead of searching the whole area. The Mavic 2 enterprise already has the IR imaging camera installed and could provide search rescue easily
How to search and rescue by Thermal Drones:
Drones can be equipped with thermal imaging cameras such as DJI Matrices 210 drone with a Zenmuse XT thermal FLIR camera that helps police or first respondents.
For example in blizzard during the night a man had a car accident, but police found him by using a thermal imaging camera carried by a drone. Through Infrared (IR) thermal imaging camera, police officers quickly could scan an area and locate a person without the need for large expensive manned aircraft.
Payload Drop by Drones:
Drones have the capabilities to drop payloads. They can provide life-saving tools, food, communication devices, supplies, etc to suspects easily instead of with the help of manpower.
For example, during flood situations suspects are fully covered with water from all sides and a drone can drop a payload to provide the life jackets and food.
Efficiency by using drones:
The efficiency of a team with the drone is almost 3 to 5 times greater in Search and Rescue than without a drone.
