Frequently Asked Questions
RAW files contain 16-bit of color data per channel. Converting to TIFF applies professional dcraw processing. Lossless output preserves all processed image data.
dcraw automatically applies the camera's recorded white balance settings from your Phase One RAW file. For creative control over exposure and color temperature, use dedicated RAW software like Lightroom first.
The web interface handles one file at a time. For batch processing, use the authenticated API (/v1/convert) which supports automated workflows.
Your Phase One RAW file is uploaded via encrypted TLS, processed using dcraw, and automatically deleted immediately after conversion. We never store or analyze your photos.
The web converter accepts files up to 25MB (Pro: 500MB). Most RAW files from consumer cameras fit within this limit. High-megapixel cameras may produce larger files suited to the API.
Phase One RAW files from Phase One medium format digital backs require specialized software: Phase One Digital Photo Professional, Adobe Lightroom, Capture One, or RawTherapee. ChangeThisFile uses dcraw for server-side processing without requiring any software installation.
Phase One RAW captures full sensor data with 16-bit per channel, preserving maximum detail and dynamic range. Unlike in-camera JPEG, RAW files let you adjust white balance, exposure, and color in post-processing without quality loss.
The conversion focuses on pixel data. EXIF metadata (camera settings, GPS, date) from the original Phase One RAW file is not carried to the output. Keep the original RAW file if metadata preservation is needed.
RAW processing with dcraw typically takes 5-20 seconds depending on file size and server load. Large 16-bit RAW files require more processing time than standard images.
