Technical note

How ND2 and JP2 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. JP2 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. ND2 stores pixels without compression loss and JP2 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.

FAQ

ND2 to JP2 Conversion

What are ND2 files?

ND2 is the native image format of Nikon NIS-Elements microscopy software. The name refers to N-dimensional data, since a single file can contain multiple channels, focal planes, time points and stage positions along with the acquisition metadata.

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
