Dynamic Photo HDR vs HDR-Merge

Dynamic Photo HDR is Windows software for merging exposures into HDR images or creating an HDR-style result from one image. It supports RAW files and provides tone mapping that ranges from smooth, natural treatments to dramatic or painterly effects. Source images can be aligned automatically, manually, or with auto-assist. An anti-ghosting mask lets users paint over moving objects in source shots, while batch processing queues images and can align them automatically. The editing toolkit includes effect layers and effects such as Orton, Sepia, Black/White, Vignette, and Mysterious Light. Real-time preview and advanced denoising are listed, along with Match Color for matching a tone-mapped image to another photo or painting. Output formats include JPG, PNG, BMP, TIF, Targa, 16-bit TIFF, and layered PSD. The product page identifies version 6.1, build 14/11/2017. It is described as a 64-bit Windows application, with a 32-bit version also linked. The listed price is $59 as a one-time purchase.

HDR-Merge is a web platform for AI HDR photo enhancement and 360° stitching. It detects exposure sets, combines bracketed images, and applies tone mapping automatically. Each HDR merge accepts three to nine exposures, and the service supports both RAW and JPEG files. Optional AI processing adjusts color, contrast, and detail. HDR images can be stitched into 360° panoramas in the cloud. HDR-Merge also describes bulk processing for hundreds of bracketed sets, with batches of 1,000 or more images. The browser-based service requires no installation or GPU and works on any device with a browser. AI-enhanced outputs are listed at 4K or 2K. Plans start at $27 a month, with no free plan but a free trial. Starter includes 150 credits monthly; Pro includes 400 and bulk processing; Agency includes 1,800, unlimited bulk processing, and 24/7 phone and email support.
