Technical note

How ND2 and AVIF differ in practice

ND2 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. AVIF 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. A scientific camera records 16 bits per pixel, and the signal of interest often occupies a narrow slice of that range, while AVIF shows 8. Conversion applies a display mapping, so two acquisitions that look identical afterwards can hold very different underlying intensities. Treat the AVIF output as something to look at and publish rather than something to measure.
