All could benefit from tutorials in the "develop" area of Lightroom, as many of the controls are familiar from Photoshop. Julian methodically worked through the different sliders and controls using cleverly picked photos which demonstrated the exact image adjustments. Never has the "clarity" slider been so clear!!
Julian has his own flickr stream - julian_r "the rousey" and also can be found giving a fuller exploration of lightroom at royal photographic society London regional workshops (next one 23rd November): http://www.rps.org/region/london/events/view/3292
