Topaz Glow introduces a new kind of tool designed to electrify your imagination by illuminating the contours of your images to reveal the hidden life in each moment you capture. Glow 2 gives you the power to create stunning neon effects, or subtle ethereal glow.

New features in Glow 2 Include:

- Over 30 New Presets (for a total of over 100 included effects)

- New Masking Module: You no longer need a host editor such as Photoshop to create masks on your images! Now, you can open Glow 2 and mask areas of your image directly from the application using luminosity, color selection, a spot mask, or a traditional brush mask, and it’s color aware!

- Unlimited Undo/Redo: As long as you don’t close the program you can now undo or redo to your heart's content (as far as your system memory will allow)

- Topaz Community Integration: Topaz Glow 2 is the 3rd of their products to include the Topaz Community, an easy way for users to search, save and share custom-made presets with other Glow 2 users around the world. Surf an ocean of hand crafted presets, then download and apply with a click

- Automatic Preset Backup: As long as you’re signed into your account when you save a preset, that preset will be privately uploaded to the community, then synced on any other machine you sign into.

NEW SYSTEM REQUIREMENTS
Glow 2 requires Windows 7+, Mac OSX 10.9+, and a GPU with OpenGL 3.3 or higher (this replaces the older requirement for OpenGL 2.1)
