PhotomatixCL vs SNS-HDR

PhotomatixCL is a command-line interface for adding HDR image processing to automated imaging workflows on Linux, macOS, and Windows. It merges exposure-bracketed photos into HDR images and processes them with tone mapping or exposure fusion. Image alignment, ghost removal, HDR presets, and JPG, TIFF, or EXR output are included. Inputs can come from a computer or local network, or be downloaded from a web server. Each run handles one bracketed set; the bundled PhotomatixCL-Driver can process folders of sets in batches. The CLI is designed for automated workflows on cloud or local servers and does not require API integration code. Linux downloads include Ubuntu, a statically linked universal build, and an ARM build for Debian; the universal build omits lens correction. Free-plan tracking requires internet access, and the CLI fails during outages unless used in trial mode. Trial runs do not use credits but add a Photomatix watermark to output images. The listed plans include free use and paid options; paid pricing is listed from $39 one-time.

SNS-HDR processes photo sequences into HDR images and can also process single images. It reads JPEG, TIFF, RAW files including DNG, OpenEXR, and Radiance HDR. For sequences, it can align source exposures and reduce ghosting and chromatic aberration. Editing tools include masks, presets, project saving and restoration, and batch processing; the software also supports 360° panorama processing. Its controls and presets are intended to produce natural-looking results. Listed outputs include JPEG, TIFF, TIFF-8, TIFF-16, SNSX, HEIC, and HEIC-10, with HEIC output available on macOS. It runs on Windows and macOS, requiring Windows 10 64-bit or newer, or macOS 14 or newer on Apple Silicon. It integrates with Adobe Lightroom Classic as a plug-in or external editor, but not cloud-based Lightroom. SNS-HDR Lite is freeware with a commercial license. Home costs €30 a month for a non-commercial license; Professional costs €85 a month for a commercial license. The Home Lightroom plug-in handles one series at a time, while Professional adds series splitting and quiet mode; batch processing is a Pro feature. A Pro demo is available to try before purchase.
