Microscopy images
Huygens Everywhere reads with high precision nearly all mainstream microscopy file types. See File Formats for all imported and exported file types.
The best file format for saving image to is ICS2, because this format is also used by many other software packages, does not compromise data quality, and stores the image metadata and dimensions correctly. HDF5 and OME are also widely used. See File formats (https://svi.nl/fileformats).
Various parameters should be taken into account when acquiring images. The two important ones being sampling and clipping. Consult our Nyquist Calculator for the best possible sampling advise and clipping can be prevented by avoiding too much light. In general, avoid zero and maximum intensity values. See also: Acquisition Pitfalls.
Huygens can recognize and correct a broad range of imaging issues. You can read more at the Huygens Imaging Academy. For direct information on image acquisition, see this webpage: Acquisition Pitfalls.
