Technical note

Before you convert CZI to JXR

CZI is an N-dimensional acquisition rather than a picture. One file can hold several fluorescence channels, a stack of focal planes, a time series and a mosaic of stitched tiles, each recorded separately by the camera. JXR is a flat image format, so those dimensions have to be resolved into ordinary pictures, and which result is the right one depends on the work: a merged colour composite suits a figure or a presentation, while separate greyscale planes are what quantification needs. CZI stores pixels without compression loss and JXR does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.

Needed to convert my professional photos to JXR for long-term storage and was pleasantly surprised by reaConverter's handling of this format. The compression maintains exceptional dynamic range while reducing file sizes significantly compared to TIFFs. The batch processing saved me hours of work, and the quality preservation is outstanding - perfect for my HDR photography archive.
