Familiar interface with clear-cut options
Fusion is wrapped in a clean and intuitive GUI made from a regular window with a neatly organized structure, where you can import image files with the RAW, JPEG, TIFF or BMP format. An important aspect worth mentioning is that the app is capable of processing multiple photographs at once.

Easily create HDR photos
These can be previewed within the main frame, along with their histogram. It is possible to add extra images for processing or remove existing ones from the batch list, zoom in and out, as well as to start the summation and tone mapping operators. Just keep in mind that all selected pics must have the same dimension in order for the HDR conversion procedure to work.

Customize image preferences
As far as configuration is concerned, you can adjust settings pertaining to the tone splitting, quality, histogram bounds, contrast, color saturation, and temperature. Changes can be previewed in real time before committing them, while the project can be saved to file and resumed at a later time.
