Alien Skin Exposure X4 4.5 for Mac is a non-destructive RAW photo editor and organiser from Alien Skin Software, the company that rebranded as Exposure Software shortly after this generation. It was designed as a fast, complete home for a photo shoot on macOS, from browsing and culling through to detailed edits and creative film looks, all without a catalog import step.

Version 4.5 is a later point release in the X4 line, now a legacy edition; today's Exposure X7 is the version Exposure Software sells and supports. X4 was paid software on a perpetual licence, never a free full version, so go to the official site for the current trial and price.

Key Features

  • Catalog-free photo organising with smart collections, keywords, ratings and fast culling
  • Non-destructive RAW processing with colour grading, sharpening and noise reduction tools
  • Layer-based effects and brush masking for applying looks to selected parts of an image
  • Extensive preset library of realistic film simulations and modern creative looks
  • Standalone workflow plus plug-in use with Adobe Photoshop and Lightroom

How to Download

  1. Download from the official site
  2. Choose the current Exposure X7 free trial or purchase, as X4 itself is a legacy version.
  3. Install Exposure, point it at your image folders, and sign in or enter your licence to activate.

Is Exposure X4 free?
No, X4 was a paid editor sold on a one-time licence, not a free full version. Exposure Software provides a free trial of the current Exposure release, which lets you test the full workflow before paying.

What did X4 add over X3?
The X4 generation refined the organiser with smarter collections and monitoring, improved masking and layer handling, and faster performance. Those ideas were carried forward and expanded in X5, X6 and X7.
