## What is Grejn?

Grejn is built for photographers who want more control from the iPhone camera. Capture in Apple ProRAW, choose the lens that fits the shot, adjust exposure, and keep your workflow focused on image quality from capture to export.

Fine-tune the look of every photo with detailed controls for contrast, highlights, shadows, clarity, sharpness, saturation, vibrance, white balance, color grading, HSL adjustments, bloom, vignette, and grain. Save your own presets, switch between looks quickly, and create a consistent visual style without leaving the app.

Grejn also gives you practical controls that matter while shooting. Tap to focus, lock focus with a long press, choose quality or balanced capture priority, set maximum resolution, and export styled HEIF images in 8-bit or 10-bit. On supported devices and lenses, you can also save the original RAW DNG separately for more flexibility in post.
