Digital booths
Why a phone camera’s JPEG is more than sensor data
Demosaicing, denoising and tone adjustments shape the ready-to-share image.
A smartphone JPEG may look polished straight from capture because the camera pipeline has already transformed raw measurements. This matters when comparing devices or recreating a consistent strip style.
Trace the rendering stages
A digital camera pipeline can demosaic filtered sensor data, reduce noise, sharpen edges and adjust white balance, colour and tone before saving a processed image. RAW capture preserves more opportunity to render those choices later, when the device supports it.

Compare like outputs
Use the same subject, light and print size when comparing phone models. A default JPEG may contain different noise reduction or sharpening from another camera’s default, so compare the final booth result rather than treating pixel values as neutral sensor readings.
Lock a repeatable style
Record the device, camera app, processing mode and export profile. An operating-system update can alter image processing even if the booth layout is unchanged. Keep a reference strip and rerun a short comparison after meaningful camera changes. These stages are not always separately controllable in a phone camera, so record the final rendered output as well as settings.
