I wish to advise to the phantastic product SLEEKLENS wich has very good presets for Lightroom and cuts down the editing time during processing the pictures. Sleeklens is a Danish design company dedicated to the field of professional photography. Author of Lightroom / Photoshop products for keen photographers.
I work with Lightroom since several years and I am really happy to use Sleeklens.
