FTS to EXR conversion is the process of transforming image data stored in FTS (Flexible Time Series or FITS-like telescope science) file containers into the OpenEXR (.exr) high-dynamic-range image format. This conversion maps multi-channel, high-precision astronomical or scientific pixel data and metadata from FTS into EXR's floating-point channels so the imagery can be used in HDR compositing, VFX, or scientific visualization workflows.

The FTS file format typically uses the MIME type application/octet-stream and is common in spectroscopic data storage. EXR files use the MIME type image/extra and support multiple codecs such as OpenEXR's PIZ and ZIP compression for efficient storage. FTS conversion to EXR is ideal for visualizing scientific data in high dynamic range environments for detailed analysis and editing.
The EXR (.EXR) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like FTS.
While specific technical details aren't available here, EXR files generally serve the purpose of storing image effectively within their domain.
Convert your FTS files to EXR format effortlessly using our online converter. Designed to provide fast and accurate file conversion, our tool supports the popular scientific FTS format and the high-dynamic-range EXR image format. Whether you are working in imaging, scientific research, or graphic design, converting FTS to EXR has never been easier.
FTS files are primarily used in scientific applications for storing spectral data, while EXR is a versatile, high-dynamic-range image format commonly used in visual effects and professional imaging. Unlike FTS, EXR supports multi-channel data and greater color depth, making it ideal for advanced image compositing and manipulation. Converting FTS to EXR allows you to leverage the powerful features of EXR for enhanced image processing.
Keep original precision: when preserving scientific detail, convert FTS floating-point channels to EXR float/half rather than 8/16-bit integer to avoid data loss.
Optimal file sizes: for most workflows use half (16-bit float) EXR to balance precision and file size; expect EXR files to be 2–6x larger than compressed FTS depending on compression.
Batch conversion: process multiple FTS files with a scripted tool (ImageMagick + OpenEXR tools or custom Python/astropy scripts) to preserve headers and apply consistent channel mapping.
Quality preservation: if your FTS contains multiple extensions or WCS metadata, export extensions to separate EXR channels or save WCS in sidecar metadata to retain scientific context.

Format limitations: EXR is ideal for HDR and multi-channel data but is not a replacement for specialized FITS metadata support; some astronomy-specific headers may not map directly into EXR and require sidecar files.
