The Power of Luminosity Masks with Sean Bagshaw

Event info

This talk is an introduction to the power of luminosity masks.

The more fine control we have over image adjustments the better we are able to create high-quality results and achieve our creative vision. In Photoshop, how skilled we are at creating masks largely determines how much control we have over our adjustments. Pixel-based masks, such as luminosity masks, represent the highest form of mask making. In this presentation, Sean Bagshaw will provide an introduction to what luminosity masks are, how they are made and ways they can be used to make very fine, nuanced and natural image adjustments.

Sean Bagshaw is a landscape and travel photographer, photography educator and experience junkie based in Ashland, Oregon, USA. His full-time photography career started in 2004 and before that was a middle school science teacher. He began taking photos in college to record and share his adventures on rock climbs and mountaineering expeditions. Over time his photography evolved from being documentary to creative. Now he spends a lot of his time chasing light, sleeping in a van, eating bad food and avoiding showers.

Photography has provided Sean with some wonderful opportunities. At the top of the list are being a member of the photography team, Photo Cascadia, and working with Tony Kuyper, the luminosity mask pioneer.  These talented folks are his travel companions, business partners, close friends and constant inspiration.

His previous career as a science teacher makes photography education a good fit so when he's not creating Sean enjoys teaching and sharing what he knows about photography and image developing with others. He teams up with fellow Photo Cascadia members leading workshops around the world. He also teaches digital image developing classes, lectures and offers Photoshop video tutorials through his website and YouTube channel.
