MergeHDR vs Photomatix Pro

MergeHDR detects exposure-bracketed photos in a library and merges them into HDR images after approval. It identifies three-, five- and seven-frame groups using metadata such as capture time and exposure values. Users can select alignment and one of four deghosting levels, then switch tone-mapping presets without repeating the merge. The app reads and writes through Apple Photos; its App Store listing also says it can connect to an FTP server to merge brackets directly from a camera. Listed inputs include Canon CR3, Sony ARW, Nikon NEF, Fujifilm RAF, Olympus ORF, Panasonic RW2, DNG, Apple ProRAW, HEIC and JPEG. Merged images can be saved at full quality or compressed to HEIC. Merging and previewing are free; the first 10 exports are free, with a limit of five free exports per day. Unlimited saves cost $9.99 a year or 19.99 USD once, with Universal Purchase for iPhone, iPad and Mac. Processing runs locally and offline, according to the maker, and the stated privacy label is Data Not Collected.

Photomatix Pro combines bracketed photos into HDR images, bringing out detail in both dark and bright areas. Version 7 offers six HDR methods, including Tone Mapping and Fusion, with advanced tone-mapping controls. Automatic alignment handles hand-held shots, and ghost-removal tools address movement between frames. Batch processing includes previews; presets and tools are also provided for real estate photography. Lightroom and Capture One plugins let users process photos and return the HDR image to those applications. The trial has no time limit, but trial-mode images carry a watermark. Photomatix Pro 7 costs $99, paid once; its license is a one-time purchase for one user and does not expire. The Pro Plus Bundle costs $129, paid once. PhotomatixCL offers command-line merging, processing, alignment, ghost removal, and JPG, TIFF, or EXR output; its free plan includes 100 credits per month. Photomatix Pro is listed for Windows and macOS, while the CLI runs on Linux and Windows.
