Download Photoshop version of Clari-Fi Pro

The Photoshop version of Clari-Fi Pro is a Creative Cloud plug-in, which should work on both Mac and Windows versions of Photoshop. In order to install this, you will need to have both Photoshop and Adobe Creative Cloud (which is free).

The Clari-Fi Photoshop plug-in is downloaded as a zip file. This zip file also includes a separate plug-in for measuring the contrast difference between foreground and background, using the Accessible Perceptual Contrast Algorithm. Find out more about APCA.

The current version of the Clari-Fi Photoshop plug-in is 1-2. See version history

The APCA plug-in is free to use and does not require a licence key. The Clari-Fi plug-in will initially run in ‘free demo’ mode, which will add watermarks to the images. These watermarks can be removed by entering a licence key, which can be purchased by contacting (prices are shown opposite).

A PowerPoint version of Clari-Fi Pro is also available, and this uses the same licence key.
