Alien Skin Blow Up 3.1 for Mac
Mac Photo & DesignAlien Skin Blow Up 3.1 for Mac is an image enlargement plug-in made for photographers who need a small file to hold up as a large print. Instead of simply stretching pixels, it analyses edges and detail so posters, canvas wraps and exhibition prints stay crisp and natural.
Blow Up was created by Alien Skin Software, the company now known as Exposure Software. This 3.1 release is the mature Blow Up 3 generation, sold as a paid plug-in rather than a free tool. The same technology now lives inside the current Exposure X7 Bundle, so Blow Up 3.1 is a legacy version for older workflows.
Key Features
- High-quality enlargements designed to keep edges sharp without obvious halos or jagged artefacts
- Crop and Resize, Resize, and Stretch modes for exact print sizes and paper proportions
- Print-ready presets for common paper, canvas and photo sizes with output sharpening controls
- Grain control that can add a natural texture to very large enlargements
- Works as a plug-in for Adobe Photoshop and Lightroom, and as an external editor from Exposure
How to Download
- Download from the official site
- On the Exposure Software page, look at the current Exposure X7 Bundle, which includes the Blow Up enlargement tools, and its trial or purchase options.
- Install the software, restart your host app if needed, and open Blow Up from the Filter or Automate menu.
Is Alien Skin Blow Up free?
No, Blow Up was a paid plug-in, not a free full version. Exposure Software offers a free trial of the current Exposure line, which is the official way to test the enlargement tools today.
Does Blow Up work on its own?
Blow Up is designed as a plug-in and does not run as a normal standalone editor. You launch it from Photoshop, Lightroom or Exposure and apply your output size there.
