HDR – or High Dynamic Range – is a digital photography technique using multiple levels of light intensity to make the most of these exposures. HDR images can record a great range of luminosity levels.

HDRinstant is based on state-of-the-art image processing technology inspired by astrophotography techniques.

From a video sequence, the software creates long exposures by stacking images, thus enhancing the quality of the photo by increasing the signal-to-noise ratio.

HDRinstant is currently available on Windows (64 bits) and macOS (from 10.13).

Yes. You can download a free trial of HDRinstant on this page. The free trial does not expire but adds a “HDRinstant” watermark to your final results when exporting.

For best results, we recommend you to use :

• A high-quality video: 4K, UHD or HD.
• A video with a high number of Frames Per Second (or FPS). This will allow you to easily select the image you want to process.

HDRinstant processes video of various exposure levels. However, our technology will work even better with underexposed video.
