Infrared Digital Negative File
The IR Image format that uses the file extension .idn is a format created to archive older infra-red image formats due to them no longer being supported by infra-red cameras available today.
IDN files contain
» Embedded image metadata
» Analysis tools and results stored in the image
» Colour pallets
» Compression/Decompression algorithms
» Lossless data compression
» Interpolated Images
To overcome this problem the Professional Thermographers Association and Ford the Motor company have funded a development program to help solve this program by creating a cross platform format which will make it easier to convert and upgrade older infra-red image formats, the result of this development is the Infra-red Digital Negative which is now becoming the standard format for archiving IR Images from multiple infra-red cameras.
