Aerial images can give viewers a singular perspective that differs from their everyday visual expertise, and subsequently can bring novelty to an image.
How is aerial pictures achieved? Of course, it involves flying up into the sky. This may be divided into two classes: manned aerial photography and unmanned aerial images, with manned aerial photography additional divided into fixed-wing plane and helicopters. In this text, I will only talk about unmanned (drone) aerial pictures, and only for static images, not video, as that’s one other topic of its own.
Why Photographers May Dismiss Drones
When it comes to drone pictures, many diehard photographers tend to dismiss it. The causes can be as follows:
1. Toys. How can these little “toys” produce severe photographic works? Serious works should come from severe gear, and professional photographers should be well-equipped.
2. Vibration. The small drone keeps vibrating, and the pictures are blurry. Even once I take handheld panorama shots, I really feel unprofessional, let alone utilizing a shaking platform. It’s solely appropriate for play.
three. Image high quality. How good can the image quality of a small camera be? I am not impressed with even the newest Sony 60mp full-frame digital camera, let alone this toy.
These may all be legitimate reasons, however critics of drone pictures typically forget a primary precept: the worth that viewers assign to a photographic work is commonly unrelated to the technical high quality or image decision. Otherwise, that 3-inch photo of “Billy the Kid” would have been thrown in the trash long ago.
Expensive gear doesn’t necessarily produce priceless works. The value of a piece is set by the author’s creative vision and the distinctiveness of the characters/scenery/event recorded by the digicam. Image quality and technology are undoubtedly essential components of pictures, however the commercialization of images today has elevated their importance to an unparalleled level.
The Uniqueness of Drone Photography
So, what makes drone photography unique?
1. Height. No matter how we argue, with out an plane, how can we carry our camera as much as the sky to take photos? Even if we now have a 100-meter-high tripod, I can assure that it shakes more than a drone. Our solely option is to photograph on the bottom. The world is three-dimensional, giving up one dimension (height) means giving up numerous perspectives, especially those views that are not acquainted in our every day life.
2. Portability. Using a helicopter with high-end pictures equipment is considered professional, and this child’s play is considered inferior. This view additionally has some advantage. But I’m sorry: except the helicopter is mine and the pilot is my servant, I can’t just do whatever I need, and I would lose most of my capturing opportunities.
My first drone was a DJI Phantom four Pro, which I soon changed with a DJI Mavic 2 Pro due to its portability. Today’s drones are the dimensions of cameras and might coexist in the identical backpack as my camera, so I can take them anyplace I go. I can modify the camera’s peak in accordance with my composition needs at any time: whether to shoot on the bottom with a tripod or in the sky, and even if I get up in the middle of the evening, I can still fly. The greatest digital camera is the one found the place you need it to be.
I was capturing autumn colors in Colorado. The colours have been stunning, and the light was beautiful. I noticed that the ripples on the lake had been particular, so I took out my drone and shot from above. This convenience is irreplaceable by any other means. Even a helicopter can not method the floor of the lake with out destroying its texture.

That’s sufficient to buy every passenger a comparatively inexpensive drone. This hour consists of travel time to and from the capturing location, so the actual taking pictures time is probably only half an hour or much less. Unless I am a tycoon (or have a tycoon bankrolling me), I am destined to not have the flexibility to afford it. On my recent trip to Iceland alone, my drone flew for practically forty hours. Using a helicopter would have been an unimaginable expense.
4. Height. Compared to helicopters, drones have altitude restrictions. The Federal Aviation Administration within the United States limits drone flight heights to a hundred and twenty meters, which is not corresponding to the heights that helicopters can attain. In certain shooting circumstances, similar to wildlife images, a certain flight peak is necessary to keep away from disturbing the animals. However, being low doesn’t necessarily mean it’s a disadvantage. For example, drones can seize particulars on the ground at a top of a few meters. Can’t try this with a helicopter. Even if the pilot is very skilled, the dust raised by the helicopter will instantly overwhelm the world.
I went to Iceland’s famous Diamond Beach. It was crowded with vacationers and had been photographed numerous instances. I had no want to take out my digital camera and could only take out my drone to look for a new perspective. After exhausting three batteries and flying for an hour and a half, I saw a heart-shaped wave. So, I had my drone waiting at a top of about ten meters until an ideal wave came again after which took the shot.
I can’t think about another implies that would permit me to look freely, wait patiently, and take pictures without any danger of being swept away by the waves, no matter price.
Photo by John Fan 5. Range. Helicopters or fixed-wing plane can fly lengthy distances, whereas drones can only fly several kilometers, which is commonly a limitation. But such comparisons are often misguided: a manned aircraft should take off from an airport, while drones all the time take off from my side. Drone photographers are already at the shooting location before they fly their drones.
6. No pilot. Often, the pilot can be the tour information. The helicopter pilot will take you directly to the scenic spot, which could be very environment friendly. The “pilot” of the drone is the photographer himself, who might have to search out the scenic spot himself, which is more work. Is this a foul factor for creativity? Of course, there are additionally drone photographers who have tour guides take them to the scenic spots, which is one other matter. Helicopters all the time have tour guides, however drones provide the freedom to interrupt away from them. There isn’t any creativity with out freedom.
I walked alongside a distant riverbank. Not even a life animal nearby, not to mention a tour information. I launched my drone and noticed the texture of the ground. Half an hour later, a stream dyed golden by minerals attracted me, so I flew and took pictures at a top of over ten meters, and stitched 4 photographs into the final work, “God’s Palette”.
Photo by John Fan Image Quality in Drone Photography
Let’s talk about picture quality, which is probably the most substantial argument in opposition to drone photography by opponents.
Speaking solely concerning the camera, the 20-megapixel camera geared up on a drone is superior to the picture high quality of high-end DSLR cameras from several generations ago. Does that imply the history of human photography solely goes again a couple of years? How in regards to the images hanging in museums? Should we hand over photography today simply because the most effective digicam obtainable right now will be junk in ten years?
The latest drones have reached a crucial point in terms of portability and picture quality and can now meet the wants of great photography.
The important drawback that drone images wants to overcome is movement blur. A drone (and any aircraft) is a shifting platform, and its vibration may cause motion blur. Motion blur is a technical problem that requires technical solutions. So, how will we overcome or at least cut back it?
1. Gimbal stabilization. Today’s drones used in images are outfitted with gimbal stabilization, which significantly reduces blurring caused by vibration. Most of today’s drones have a three-axis mechanical gimbal stabilization system. Although not the most cutting-edge stabilization expertise, there may be presently no higher possibility for transportable drones. Waiting for stabilization expertise to unravel every little thing would make us lose all causes for aerial photography.
This is a photo I took in Iceland in 2018 utilizing the DJI Phantom four Pro, flying at a peak of dozens of meters with a wind pace of about 30 kilometers per hour.
Photo by John Fan Note the ropes on the bottom as railings, which are nonetheless clearly seen in the 1:1 crop.
Photo by John Fan 2. Increase shutter speed. I generally use a shutter speed sooner than 1/100 second. Without image stabilization, a handheld camera’s shutter pace should be quicker than 1/focal length. The theoretical handheld shutter speed limit for the 28mm camera on the DJI Mavic 2 Pro is 1/28 second. With a speed of 1/100 second and the help of the stabilizing gimbal, the impression of jitter is comparatively small.
three. Try to avoid flying in sturdy winds. My motto is that if an individual can’t stand still, a drone won’t be secure, and it may be blown away by the wind and never return. We should know when to surrender.
4. Post-processing. Sharpening in post-processing can certainly enhance sharpness, however over-sharpening could make the image look harsh and unnatural. Today’s AI technology takes a very completely different strategy. It “guesses” and fills in lost particulars primarily based on the feel of the picture and the knowledge it has learned, quite than sharpening indiscriminately. For a high-definition picture taken with a digital camera on a tripod, its effect just isn’t vital. But for drone pictures with movement blur, its impact could be large. In the past few years, I have used it extensively to course of aerial photographs.
For the same picture, in a 1:1 crop, the sharpness of the rope is tremendously improved by the sharpening processing of the AI sharpening software program, and the stones on the bottom are additionally clearly visible. Even if a DSLR digicam is mounted on a sturdy tripod with a 24mm wide-angle lens and used to photograph a rope tens of meters away in 30 km/h winds, how a lot sharper can it be?
Photo by John Fan Instead of worrying about decision, it’s better to open our arms and embrace this new period. Our era will never be perfect as a end result of by the time it reaches “perfection,” it would be one other imperfect new period, and we would have turn into irrelevant to our then-current era in the future. Imperfect drones have undoubtedly turn out to be one of many severe tools for photographers.
Things to Pay Attention To
So, what ought to we take observe of in drone photography?
1. Drone pictures can also be photography, not a toy. The only difference between it and other types of panorama photography is the height of the “tripod”. Without unique mild, moments, and composition, pictures taken from excessive up may also be junk. Often, photographers would carefully set up their cameras on tripods when gentle is good but will fly their drones when there’s nothing to do. How can mediocre mild produce exceptional work?
Overcast skies are widespread in Iceland. Waiting for sunrise or sunset to seize colour in clouds is often in vain. This night, darkish clouds hung over the sky, so it was best to go to mattress early. Perhaps it was a blessing from above, but in the middle of the evening, I woke as a lot as see a touch of red color on the horizon. I rapidly went out to take a picture, however the composition on the ground was not satisfactory.
In order not to disturb others, I flew my drone distant from the campsite and captured a wide ranging view of the entire valley. The battery died after solely half an hour, and the light disappeared. There were less than forty five minutes of excellent lighting. The convenience of the drone allowed me to capture such an impressive scene.
Photo by John Fan Under backlight circumstances, I had to underexpose by one stop to keep away from overexposure and brighten up the shadows by two to three stops in post-processing. I used 24 drone images to sew collectively a 200mp panoramic picture.
Some may grumble that 200 million pixels are useless if it is blurry. Let’s have a look at a 1:1 crop of a small piece a couple of kilometers away in the midst of the image. How many DSLR cameras on tripods with wide-angle lenses can seize distant objects a few kilometers away with larger clarity?
Photo by John Fan 2. Drones usually are not meant to be used as a shortcut to onerous work, they usually can’t substitute the photographer’s on-location expertise of the scene and the inventive inspiration that comes from it. Simply flying over a scene might allow you to capture it, but it won’t necessarily lead to a great shot.
3. High viewing angles might not always be the best choice for a specific scene. Aerial photography (including helicopters and drones) may be the worst composition alternative for some scenes. For instance, when making an attempt to seize a towering mountain, the shortage of foreground components might result in a flat image without depth. It might be higher to stay on the bottom and use a special perspective to capture the scene. Conversely, for a flat and featureless landscape, looking at it from above with a drone can reveal many textures and patterns not ordinarily seen by human eyes. Remember, a camera is just a tool, not the only device.
Even an ordinary water flow can reveal one thing distinctive when seen from a different angle.
Photo by John Fan 4. Finally, it could be very important emphasize that there are different laws concerning drone flights in different nations, and you will want to understand peak restrictions and no-fly zones. It is not price getting in bother. It is best to avoid flying over people’s heads in crowded areas and avoid causing resentment towards photographers.
