Technical note

How ND2 and BMP 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. BMP 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 BMP shows 8. Conversion applies a display mapping, so two acquisitions that look identical afterwards can hold very different underlying intensities. Treat the BMP output as something to look at and publish rather than something to measure.

This online converter works perfectly for small batches of files. I occasionally need to convert BMP to JPG, and it doesn't make sense to install software for such simple tasks. It's much easier to just visit the site, click a couple buttons, and get the same quality result in seconds.

FAQ

ND2 to BMP 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 BMP files?

The BMP or Bitmap file format is a popular raster graphic format, compatible with a wide array of image processing software, both on PC and Mac computers. BMP files store grids of pixels and detailed information concerning color tones and shades, and are highly appreciated for their ability to provide increased quality images. However, due to the lack of any compression algorithm in storing pixel data, BMP images can often be very large in size and thus difficult to store or transfer.
