Panning is a fundamental camera technique in cinematography and photography, where the camera swivels horizontally from a fixed position. The speed at which the camera pans is crucial to achieving the desired effect. A faster panning speed can create a sense of motion and energy, while slower panning can provide a more stable and detailed view. The shutter speed, frame rate, and other factors also play a significant role in the outcome of the image. Ultimately, the aesthetics of the panning shot depend on the creative vision and the mood of the scene.

The rule of thumb is to pan no faster than a full image width every seven seconds
Panning refers to swivelling a still or video camera horizontally from a fixed position. When photographing a moving subject, the panning technique is achieved by keeping the subject in the same position of the frame for the duration of the exposure. The exposure time must be long enough to allow the background to blur due to the camera movement as the photographer follows the subject in the viewfinder.
Photographers use aids such as tripods and monopods to help with panning, making it easy to swing the camera along one plane while keeping it steady in the others. The rule of thumb for panning speed is to pan no faster than a full image width every seven seconds. This rule is based on traditional theatrical viewing at 24 fps with a 180° shutter angle. However, this is not a strict limit, and images will not become unwatchable if they exceed this limit. It is just a good starting point, and other factors may also modify the effect.
The shutter angle controls the balance between stuttered and blurred panning. Larger angles cause panning to appear smoother but more smeared, while smaller angles cause panning to appear crisper but choppier. The frame rate can also impact panning. Capturing at a higher frame rate (e.g., 48 or 60 fps) can smooth high-frequency camera movements if played back more slowly (e.g., 24 or 30 fps). Alternatively, high frame rate playback can reduce the appearance of judder or other artefacts without decreasing the panning speed.
In addition to panning speed, shutter angle, and frame rate, other factors may be important, such as variable panning speed. The panning rate may need to vary, especially when tracking a subject that passes near the camera. In that case, the rapid pan when the subject is closest typically doesn't need to be held to the same standard as constant panning. Ultimately, what matters is whether the panning looks good to the viewer and fits the mood of the scene.

Shutter speed: slower speeds create a greater motion blur, faster speeds minimise blur
When panning a camera, the shutter speed plays a crucial role in achieving the desired effect. Adjusting the shutter speed can create either a motion blur or a crisp, clear image.
Slower shutter speeds allow for a greater motion blur, which is ideal for capturing a sense of movement in an image. This technique is often used to keep a moving subject sharp and in focus while creating a streaky, blurry background. The amount of motion blur depends on the speed of the subject, the focal length of the lens, and the distance from the subject and background. For example, photographing a fast-moving F1 car may require a shutter speed of 1/250 second to achieve a blurred background, while capturing a running person at the same speed would result in a much blurrier background.
Faster shutter speeds minimise motion blur and are useful when you want to capture clear, sharp images of fast-moving subjects. This technique is often employed in sports photography or when photographing race cars, where a higher shutter speed, such as 1/125 second, can effectively freeze the action.
It is worth noting that the panning speed and shutter speed are closely related. A faster panning speed may require a faster shutter speed to avoid excessive motion blur, while a slower panning speed can accommodate a slower shutter speed, allowing for a smoother, more fluid effect.
Additionally, the shutter angle also influences the appearance of panning. A larger shutter angle will result in a smoother but more smeared image, while a smaller angle will create a crisper but choppier effect.
Ultimately, the choice of shutter speed depends on the desired effect and the subject being photographed. Experimentation is key to finding the perfect balance between shutter speed and panning speed to achieve the desired level of motion blur or clarity in your images.

Frame rate: capturing at a higher frame rate can smooth detrimental high-frequency camera movements
Frame rate, expressed in frames per second (fps), refers to the number of frames a camera captures in one second. The higher the frame rate, the smoother and more fluid the video will appear. This is because a higher frame rate results in more images being captured in a given time frame, providing a higher level of detail in the motion.
For example, a video with a frame rate of 30 fps will display 30 still images per second, resulting in a smooth video. However, a video with a frame rate of 60 fps will appear even smoother. The human eye can process up to 5 individual images per second and perceives approximately 40 fps. Thus, higher frame rates create a more realistic and smooth viewing experience.
When it comes to panning a camera, the frame rate can significantly impact the result. Panning refers to swivelling a camera horizontally from a fixed position, creating the effect of the view "passing by" as new material appears on one side of the screen and exits from the other. A higher frame rate can help smooth out detrimental high-frequency camera movements during panning. For instance, capturing at 48 or 60 fps can reduce the appearance of judder or other artefacts when played back at a slower frame rate, such as 24 or 30 fps.
Additionally, a higher frame rate allows for more flexibility during the editing process. It is worth noting that the decision of frame rate depends on the specific application and the available bandwidth and computing capabilities. While higher frame rates are ideal for capturing fast-moving subjects or high-speed actions, they may not always be necessary or feasible, especially at extremely high resolutions.
In summary, a higher frame rate can smooth detrimental high-frequency camera movements during panning by providing more detailed and fluid footage. This can enhance the viewing experience and allow for more flexibility in editing. However, it is important to balance the frame rate with other factors, such as resolution and available bandwidth, to ensure optimal results.

Subject distance: nearby objects transit the frame faster than the background
When panning a camera, the subject distance, or how close or far the subject is from the camera, can significantly impact the resulting image. Here are some key considerations and techniques to keep in mind when dealing with subject distance:
Nearby Objects Transit Faster Than the Background
With a constant horizontal pan, nearby objects will move across the frame much faster than the background. This phenomenon is due to the difference in relative distances from the camera. As a result, you may need to make creative and technical choices based on the location of the subject and the desired focus. For example, if the subject is in the foreground and you want them to remain in focus, you may need to adjust your panning speed or use specific camera settings to achieve the desired result.
Panning Speed and Shutter Angle
The panning speed and shutter angle can greatly affect how nearby objects and the background are captured. Slower panning speeds and smaller shutter angles are typically used to capture landscape details and create a smoother, more fluid effect. On the other hand, faster panning speeds and larger shutter angles can be used to achieve a dreamlike, dynamic feel, with nearby objects creating a strong sense of motion as they move across the frame.
Focusing Techniques
When dealing with nearby objects, focusing techniques become crucial. If you are unsure of the subject's distance or are a beginner, autofocus is your best friend. Set your camera to continuous focusing mode (AF-C on Nikon and Sony, AI-Servo on Canon) to ensure the camera continuously focuses on the subject as it moves. If you are confident about the subject's distance and path, manual focus can be used. Identify the subject's position and pre-focus on that point, then simply pan your camera along and capture the shot.
Shutter Speed
The shutter speed plays a vital role in capturing nearby objects. A faster shutter speed is required to freeze fast-moving objects clearly, while a slower shutter speed can introduce blur. The shutter speed needed will depend on the speed of your subject—the faster the subject, the faster the shutter speed. For example, a shutter speed of 1/1000 is suitable for most sports, while 1/2000 to 1/4000 is recommended for capturing sharp images of birds in flight.
Artistic Expression with Blur
While the goal is often to capture clear images of nearby objects, don't underestimate the artistic value of blur. Blur can be an excellent way to convey motion and speed. For instance, car advertisements often use blur to suggest speed. Experiment with different shutter speeds and panning techniques to create artistic images that showcase the motion of nearby objects.

Swish pans: used for snapping quickly between subjects, rendering almost everything blurred
Swish pans, also known as whip pans, are a unique camera technique that involves rapidly transitioning between subjects or scenes, resulting in a brief blur effect. This technique is often used to create a disorienting or dreamlike effect, transporting the audience through time and space.
To achieve a swish pan, the camera is rotated quickly on the x-axis, usually beginning and ending with the camera at rest. This rapid rotation causes the image to blur, creating a striking visual effect that immediately draws attention. The speed of the pan can vary, but it is typically performed faster than the traditional rule of thumb, which suggests panning no faster than a full image width every seven seconds.
When performing a swish pan, it is important to maintain a consistent direction of rotation. Combining two swish pans in the same direction can create interesting effects, such as simulating a clone or doppelganger, while transitioning from scene to scene. Additionally, swish pans can be used in the middle of a scene, rather than simply as a transition, to reset the orientation or break the 180-degree line.
The success of a swish pan depends on several factors, including the panning technique, shutter angle, and frame rate. The panning technique should be as even and continuous as possible, with smooth manual panning achieved by initiating and completing the pan before reaching the desired start and end points. A longer handle on the tripod head can also help extend hand motion, while switching to a fluid or geared tripod head can optimize tension and minimize sticking.
The shutter angle and frame rate can also impact the appearance of the swish pan. A larger shutter angle will result in smoother but more smeared footage, while a smaller angle will create a crisper but choppier effect. A higher frame rate, such as 48 or 60 fps, can help to smooth out high-frequency camera movements when played back at a slower speed.

Frequently asked questions
The rule of thumb is to pan no faster than a full image width every seven seconds, otherwise, judder will become too detrimental. This rule applies regardless of camera lens, model, or sensor size. However, this is not a strict limit, and the quality of the image will depend on other factors as well.
The shutter angle and frame rate will influence the optimal panning speed. A larger shutter angle will cause the panning to appear smoother but more smeared, whereas a smaller angle will make the panning look crisper but choppier. A higher frame rate will also help smooth out high-frequency camera movements.
A slower shutter speed is generally recommended for panning shots as it creates a motion blur effect. A good starting point is 1/30th of a second, but anywhere between 1/15th and 1/200th of a second can work as well. A faster shutter speed will freeze the subject and minimize the blur.
Photographers often use tripods and monopods to stabilize the camera while panning. This allows for smooth and steady camera movements.
