This iOS 17 setting lets you take 48MP photos on your iPhone 15 — how to enable it

 To enable 48MP photos on your iPhone 15 with iOS 17, follow these steps:

  1. Open the Settings app.
  2. Tap on Camera.
  3. Tap on Formats.
  4. Under Photo Capture, turn on the toggle next to Apple ProRAW.
  5. Make sure the ProRAW Resolution setting that appears is set to 48MP.

Once you have enabled these settings, you can take 48MP photos by opening the Camera app and tapping on the ProRAW button. This button is located in the top-left corner of the screen, next to the flash button.

To take a 48MP photo, simply tap on the shutter button. The photo will be saved to your Photos app, where you can view and edit it.

Additional notes:

  • 48MP photos are much larger than standard 12MP photos. As a result, they will take up more storage space on your iPhone.
  • You may want to consider using a cloud storage service such as iCloud or Google Photos to store your 48MP photos.
  • It is recommended to use a tripod or other stabilizing device to prevent camera shake when taking 48MP photos.
  • Make sure that your subject is well-lit.
  • Use a faster shutter speed to capture moving subjects.
  • Experiment with different ISO settings to find the best balance between noise and detail.

What is an Antenna ?

 An antenna is a device that transmits and receives electromagnetic waves. Electromagnetic waves are a form of energy that travels through space at the speed of light. They include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Antennas are used in a wide variety of applications, including:

  • Radio and television broadcasting
  • Cellular and mobile communications
  • Satellite communications
  • Radar
  • GPS
  • Wi-Fi
  • Bluetooth
  • RFID
  • Wireless security systems
  • Microwave ovens

Antennas come in many different shapes and sizes, depending on their application. Some common types of antennas include:

  • Dipole antennas: These are the simplest type of antenna, consisting of a straight wire or rod. Dipole antennas are omnidirectional, meaning they radiate and receive signals in all directions.
  • Yagi antennas: These antennas are made up of a dipole antenna plus one or more reflectors and directors. Yagi antennas are directional, meaning they radiate and receive signals in a specific direction.
  • Dish antennas: These antennas are parabolic in shape and are used to focus signals in a narrow beam. Dish antennas are often used for satellite communications and radar.
  • Omnidirectional antennas: These antennas radiate and receive signals in all directions. They are often used for indoor applications, such as Wi-Fi and Bluetooth.

Antennas work by converting electrical signals into electromagnetic waves and vice versa. When an electrical current is applied to an antenna, it creates an electromagnetic field. This field travels through space in the form of radio waves. When an electromagnetic wave hits an antenna, it induces an electrical current in the antenna. This current can then be amplified and processed by a receiver.

The design of an antenna determines its frequency range, directivity, and gain. The frequency range is the range of frequencies that the antenna can transmit and receive efficiently. The directivity is the direction in which the antenna radiates and receives signals. The gain is the measure of how well the antenna amplifies signals.

Antennas are an essential part of many modern technologies. They allow us to communicate with each other, access information, and navigate the world around us.
