Check the Lens First: A smudge or fingerprint on the camera glass is the #1 cause of blurry, hazy, or low-contrast iPhone photos. Wipe the lens with a microfiber cloth before shooting.
Set Photo Capture to 24MP: Go to Settings > Camera > Formats (or Photo Mode) and choose 24 Megapixels instead of 12MP. This provides a noticeable boost in fine detail and texture without making file sizes unmanageable.
Turn Off "Prioritize Faster Shooting": Go to Settings > Camera and toggle Off Prioritize Faster Shooting. Leaving this on forces the phone to rush image processing when you tap quickly, which heavily compromises sharpness and detail. Disabling it allows the phone the extra fraction of a second needed to properly clean up noise and stack computational clarity.
Choose Your Format Wisely: Select High Efficiency (HEIF) if you want optimized files that support advanced lighting and HDR data. If you notice weird compression artifacts or want absolute accuracy when moving files to a computer, switch to Most Compatible (JPEG).
