May Double Feature: Understanding Focal Lengths, Depth-of-Field, Bokeh, & Masking |Technical Webinar

Updated: May 30, 2023



Join us for the May Technical Webinar Double Feature: Understanding Focal Lengths, Depth-of-Field, and Bokeh plus Masking in Lightroom with Tracey Rice and Bob Chadwick!


The May Technical Webinar speakers will be Tracey Rice and Bob Chadwick and the topic will be “Double Feature: Understanding Focal Lengths, Depth-of-Field, and Bokeh plus Masking in Lightroom”. The webinar is scheduled for Tuesday, May 23, 2023 at 6:30 pm.


Every photographer needs to have a firm understanding of focal lengths, and the relationship that focal length and aperture have to depth-of-field and bokeh (that dreamy blurred out background). Tracey will explain that whether you choose a prime lens or a zoom lens, your choice of focal length will differ depending on your subject matter, the distance you are from your subject, and the type of sharp or soft background you want. Once you have that understanding, you are the master in control of making your photo match your vision.


Adobe Lightroom has added some powerful new masking features that offer a variety of local

adjustment tools in an organized panel to help you make precise edits to specific areas in a

photo with the most creative control. Bob Chadwick is going to do a demonstration of

these new masking tools, and show you how it’s possible to touch up specific parts of a photo

with just a few selections. The Masking panel in Lightroom lets you work on any portion of an

image to make intricate and precise adjustments using masks like Brush, Background, People,

and more, topped by editing controls. You can access manual masks as well as masks powered by artificial intelligence.
