I bit the bullet (0.35 calibre obviously.....) this morning and downloaded some brushes for Lightroom. There are different sets of brushes for portraits, landscapes etc and at the moment are available at a seriously discounted price of $27. I know you can make up your own brushes, I've done that myself but for $27 why would you bother? The offer is limited and is due to end very soon so if you are interested the website is www.kelvindesigns.com
