Adobe has released an update to its Photoshop Touch app for the iPad and Android tablets designed to optimise the product for smaller tablet devices, in particular those with 7-8-inch displays such as the iPad mini and  the Google Nexus 7.

Photoshop Touch is a tablet app with a workflow and toolset drawn from the full desktop version of Photoshop – though its interface has been designed around gestrue-based tablet conventions. It enables users to edit photos and artworks with layers, effects and a subset of its big brother's tools.

The latest update makes the interface more accessible on smaller devices, and introducers new sharing functionality through Facebook and Twitter.

This release also introduces native stylus support for three pressure-sensitive stylii: the Pogo Connect, Jot Touch and the Jaja.

Photoshop Touch 1.4 is a free update for current owners. For new users, it costs £6.99. It's also available through Adobe's Creative Cloud.
