Get Exposure Time from MetaData

[Ofra Golani]

Hi,

I'm reading a DeltaVision file (.dv) using LOCI bioformat importer.
Each image was taken using different exposure time.
I want to normalize each image by its exposure time, which is written in the metadata.

I want to write a simple macro that does this automatically for all the images in the file.
How can I extract  the exposure time from the metadata in order to use it later for dividing my image by this value ?

Thanks,
Ofra Golani

This macro retrieves the timestamps and exposure times for each plane,
for files in any format supported by Bio-Formats:
