I chose to write about the iPhone 14 Pro Max's camera app because it is an app I'm very familiar with and it's one of the few with which I can meet the breadth of this discussion forum's requirement. The camera app on the iPhone is also the ultimate mobile app as it allows one to take photos while on the go. As should come to no surprise, camera phones greatly outsell stand-alone cameras today.
The iPhone's camera app allows one to control the camera's hardware. The app goes beyond just controlling the hardware, however, in that it allows for the many features that can be applied to photos both before and after these are taken.
The iPhone's camera app allows the user to take portrait, slow motion, panoramic, landscape, cinematic, and square photos. The picture modes can be found just above the shutter by swiping right-to-left or left-to-right. The most innovative of these photo types are the panoramic and cinematic types. The panoramic mode allows the user to take a photo that extends outside of the viewfinder, the iPhone's screen. To take a panoramic shot, select pano found just above the circular shutter at the bottom of the screen. Then, tap the shutter and move the phone in the direction of the arrow found on the viewport. After you have captured all the subjects and/or landscape that you desire, tap the shutter again to take the picture.
The cinematic mode made possible by the app allows a subject you focus on to appear normally and the background to become blurry. This feature works mainly by adjusting the camera's focal length. The software also allows you to select a square picture mode, a mode necessary to place a selfie on Instagram. A user can switch between the front-facing camera for selfie mode and the rear-facing cameras for all other photographs, by selecting the circle containing within it both a clockwise and counterclockwise arrow. This soft button is found at the bottom right of the screen. An interesting feature of selfie-mode is the front-facing camera creates a depth map of your face, allowing for facial recognition, which is one of the ways the phone can be unlocked.
Another feature of the iPhone is the ability to zoom in or out by the photographer pinching his or her index fingers together or by spreading his or her index fingers apart, respectively. A better way to obtain complete control over the degree of focus, though, is to select either the 2X or 3X soft button found above the picture modes near the bottom of the screen. With the selection, the user is able to use a spin wheel to adjust the zoom more finely.
Another interesting feature the camera app offers is live photo mode, a mode that can utilize the ultra-wide, wide, or telephoto lens. This mode can be activated by pressing the glyph, the soft button that appears like a bullseye at the far upper right of the viewfinder. Live mode captures a second to a second-and-a half of video both before and after the shutter is selected. A similar feature offered by the software is burst photography. The camera takes approximately ten photos when the user places his or her finger on the shutter and very quickly moves said finger to the bottom of the screen in landscape mode or to the left in portrait mode. The photographer must be quick as too long of a depressing of the soft button will result in the camera going into video mode.
Many features are available only in portrait mode. One such feature involves the changing of the lighting. One can change the lighting by choosing one of the buttons directly above the portrait mode. The photographer can select from natural light, studio light, contour light, stage light, stage light mono, and high-key light mono. It is best to play around with these settings to find which one works best for the photo you are going to capture. As the name suggests, both mono modes shoot in black and white.
The iPhone also possesses features that are necessary to shoot in low-light settings. The user can use the flash by toggling the lightning bolt icon at the top left of the screen from off to on to auto. An even better option for some situations is to enable dark mode, a mode that can be turned on by selecting the moon icon also at the top left of the screen. Night mode utilizes both the hardware and software to take better photos in mid-to-low-level light. This feat is accomplished basically by slowing down the shutter to let in more light in these poorly lit situations.
Another feature used by the iPhone to create high-quality photos involves the use of HDR photography, namely, high-definition range photography. The camera takes the best of separate exposures and merges these exposures to create the best possible photo. If you are not satisfied with the iPhone's rendering, you can go into photo settings and view all the different exposures and select one that is more to your liking.
As demonstrated by the features noted above, and these certainly do not encompass all the features, the camera app gets the most out of the camera's hardware. The software, though, would benefit from an explanation of what each icon is designed to accomplish while hovering over the icon with the mouse pointer. Too many of the icons are vague, in that it is difficult to discern from the icon what its purpose is. The camera app would also be better served by saving users from having to venture back and forth between the camera settings and the view finder to tinker with the available settings.
Apple would definitely frown upon this suggestion, but I believe an instruction manual focusing on taking different types of photos should be included with every iPhone purchased. Not everyone is as familiar with photography as I am.
Photo one is illustrative of a simple portrait photo, while photo two is taken from the same position using panoramic mode. Photo three is taken in a room essentially void of light, illustrating Apple's incredible night mode. Photo four is shot in the same pitch black room utilizing the flash and achieving a much poorer result.
