The event held by Apple on October 31st attracted attention as all videos were filmed with the iPhone 15 Pro Max. Film producer and cameraman Stu Masivitz catches attention by explaining how Apple filmed the event video with the iPhone 15 Pro Max. Apple filmed the product announcement event with the iPhone 15 Pro Max and is disclosing the equipment used and the footage taken. At the Apple shooting site, the photos were taken using the same equipment used by professionals, such as a high-performance camera rig and a crane. Apple’s explanation that it was filmed with an iPhone does not promise that you can film it that way too. However, using good equipment is not necessarily necessary to shoot great videos. At the Apple filming site, high-end camera rigs and rails were used. However, such equipment is necessary to take smooth videos using a heavy camera, and is not necessary for light cameras such as the iPhone 15 Pro Max. If you are taking pictures of people in a downtown area at night, simple equipment such as two portable LED lights and a gimbal and DSLR camera are sufficient. You can also take crane shots by attaching a long stand to the gimbal and holding it. The gimbal suppresses hand shaking as much as possible and allows you to capture high-quality video. To take various shots with the iPhone 15 Pro Max, equipment such as a gimbal or tripod may be used, but basically, general sale items are sufficient and high-end large-scale equipment such as the one used by Apple for event filming is not necessary. Additionally, Apple used a free app called Blackmagic Camera, rather than the stock camera app used on the iPhone 15 Pro Max. Blackmagic cameras allow detailed settings for shooting resolution, codec, color space, etc., so Apple event videos were filmed in Apple Log. The Blackmagic camera is significantly different from the stock camera app in that it allows you to take log shots while applying LUT, a color grading preset, to the preview. Another outstanding feature of Blackmagic cameras is that shutter speed can be expressed as an angle, just like a cinema camera. Camera shutter speed usually refers to the exposure time on film and is expressed in seconds, such as 1/60th of a second or 1/200th of a second. However, because film cinema cameras rotate the shutter in a semicircle, the shutter angle is used in the film industry to measure how many times the shutter rotates per frame. Shutter speed setting is also important when shooting continuous video. For example, when shooting video at 24fps, if you set the shutter speed to 1/48 second, the shutter angle becomes 180 degrees. In the video industry, there is a rule of thumb called the 180-degree shutter rule, which states that a shutter angle of 180 degrees is just right. It is said that if the shutter angle is larger than 180 degrees, the image shake increases, and if the shutter angle is smaller than 180 degrees, the image shake decreases. In other words, it is important to have the skill to adjust the shutter angle according to the image you want to capture. Video exposure can be set to three settings: lens aperture, ISO sensitivity, and shutter speed. The iPhone 15 Pro Max lens does not have a variable aperture, so you can adjust ISO sensitivity and shutter speed to control exposure. Apple revealed that while using huge lighting equipment, the work itself was filmed at a low level. Normally, an ND filter must be used to limit the amount of light entering the lens, but it is pointed out that Apple has not been seen using an ND filter. Therefore, it is presumed that Apple prioritized image quality, avoided using ND filters, and took photos with a low ISO sensitivity setting. Lowering the ISO sensitivity reduces screen brightness but reduces noise. If you want to maximize the dynamic range of the iPhone 15 Pro Max, ISO sensitivity of 110 to 1145 is said to be optimal. Still, it is assumed that Apple lowered the ISO sensitivity because it prioritized low noise over dynamic range. Of course, Apple’s method of shooting in low light is not the best way to shoot video on the iPhone 15 Pro Max. You can create impressive images simply by setting the ISO sensitivity appropriately or adjusting the direction or color of the light. It requires expertise not only in lighting, but also in balancing light sources. Of course, if strong light is shined through a large lighting device, lens flare or ghosts will occur. To prevent this, Apple is equipped with a fairly large matte box. To summarize this expert’s advice on shooting video with the iPhone 15 Pro Max, use the camera equipment first. However, it doesn’t have to be luxurious. Use lighting correctly. Use a camera app that allows detailed settings, such as Blackmagic Camera. Use a shutter angle of 180 degrees if possible. Use a matte box or black tape to prevent light from entering the lens. Perform log shooting while applying the LUT to the preview. After filming the log, they hire an excellent color editor for color editing. Related information can be found here.
