How do I convert MEF to EXR using the LetsConvert tool?

Upload your MEF file, select EXR as the output format, and adjust optional settings like bit depth (16-bit or 32-bit) and color space. Click Start Conversion and download your EXR file. The tool automatically demosaics the Mamiya raw data for HDR output.

Why should I convert MEF to EXR instead of using JPEG or TIFF?

EXR stores linear-light data with high dynamic range, unlike JPEG's lossy 8-bit or TIFF's limited dynamic range. This makes EXR ideal for compositing, HDR rendering, and archival workflows where retaining maximum luminance and color detail from the MEF raw sensor data is critical.

How does the conversion handle color depth, white balance, and metadata from MEF?

The converter demosaics the MEF sensor pattern, applies white balance, and encodes the image as a linear scene-referred OpenEXR with lossless compression (like PIZ). You can choose 16-bit half-float or 32-bit float output. EXR doesn't embed camera metadata (ISO/shutter), but you can attach color transformation matrices to preserve accuracy.
