Feb 25, 2025 am 08:06 AMUnlock the Full Potential of Your iPhone 15 Camera: Mastering 48MP Photography
The iPhone 15's (and 14 Pro/Max's) rear camera boasts a powerful 48MP sensor, but its default setting limits you to 24MP images. This article reveals how to unleash the full 48MP capability and capture richer, more detailed photos. While there are trade-offs, understanding the available modes will elevate your smartphone photography.
Understanding iPhone 15 Camera Functionality

By default, your iPhone 15 uses pixel binning to combine pixels from the 48MP sensor, creating a 24MP image. This reduces file size and improves light capture for better image quality. However, switching to 48MP provides greater flexibility in post-processing.
While offering more detail, 48MP photos require more storage space. Professional photographers often prefer this higher resolution for enhanced editing control.

Key Differences Between iPhone Models:
The iPhone 15 and 15 Plus feature a slightly less advanced 48MP sensor compared to the iPhone 15 Pro and 15 Pro Max, despite the same pixel count. The Pro models also support Apple's ProRAW format, offering maximum control but significantly larger file sizes and requiring more advanced photo editing skills. The iPhone 15 and 15 Plus capture 48MP images in HEIF or JPEG, offering a compromise between 24MP and ProRAW.

The iPhone 15 and 15 Plus, lacking the processing power for RAW, offer 48MP photos in HEIF or JPEG. These are compressed, reducing post-processing control but significantly lowering file sizes. This option provides a middle ground between 24MP and ProRAW.
Enabling 48MP Photography: A Step-by-Step Guide
- Navigate to Settings: Open your iPhone's Settings app.
- Access Camera Settings: Tap on "Camera."
- Choose Image Format: Select either "High Efficiency" (HEIF) or "Most Compatible" (JPEG). HEIF offers smaller file sizes, while JPEG boasts broader software compatibility.
- Enable 48MP Resolution: Activate "Resolution Control" (iPhone 15/15 Plus) or "ProRAW & Resolution Control" (iPhone 15 Pro/15 Pro Max). Pro models also allow choosing between HEIF Max, JPEG Max, ProRAW 12MP, and ProRAW Max. File size information is provided for each option.
- Activate 48MP in Camera App: A 48MP option will appear in the camera app. Tap to enable it and select your preferred format (HEIF Max, JPEG Max, or RAW Max). On Pro models, press and hold to switch between HEIF/JPEG and ProRAW. Note: ProRAW is unavailable on iPhone 15/15 Plus.
- Preserve Settings: To keep the 48MP mode active, go to Settings > Camera > Preserve Settings and select either "Resolution Control" or "Apple ProRAW & Resolution Control."
Important Note: The camera will revert to 24MP for Live Photos, macro shots, Night mode, and flash, regardless of your settings.
By following these steps, you can maximize your iPhone 15 camera's potential and capture stunning 48MP images. Remember to consider the trade-offs between file size, image quality, and processing time when selecting your preferred settings.
