Monochrome is a photo editing software designed from scratch to be a photographer's digital darkroom, a tool for visual interpretation of images. As such, it is also an experimental workbench for photography-centric ideas in digital imaging.

Several innovative features are included in the current beta, and more are on the way. Here is a partial list of features:

• Nondestructive editing: Source images are never touched, and there are no sidecar files.
• Location-independent database of edits: Monochrome edits are associated with image identity, not image location, so you are free to open your images from any storage location.
• Resolution-independent: Work on sized-down copies on your netbook, then sync and open full-size images on your workstation and continue editing session.
• Multiple image versions: Make different interpretationsof an image, such as color and black-and-white. Each version maintains its own editing history.
• Full undo from first edit of an image.
• Cloud sync: Work on multiple computers. As long as you have a copy of the same image, at any resolution, you can sync and continue your editing session.
• Cloud image editing: Open and edit images directly on cloud image galleries such as SmugMug, Picasa and Flickr.
• High-precision unclipped floating point mode: With tone maps for high dynamic range editing (experimental).
• Layered image editing model with filters, brushes, shape masks and color masks
• Supports very large images using even moderate amounts of memory (current file size limit is 2GB limit due to TIFF file format limitation).
• Support for JPEG and TIFF image file formats (the most common TIFF formats are supported)
• Fully color managed workflow from input to editing to output.

Monochrome is currently a non-commercial software in beta-testing. To join the beta program, go to the Beta page.
