A method comprising: obtaining video frames captured at one or more cameras during a video conference session, wherein each video frame comprises a digital image comprising a plurality of pixels; determining depth values associated with each pixel in at least one video frame, wherein each depth value represents a distance of a portion of the digital image represented by at least one corresponding pixel from the one or more cameras that capture the at least one video frame; and adjusting luminance values of pixels within captured video frames based upon the depth values determined for the pixels so as to achieve relighting of the video frames as the video frames are displayed during the video conference session.
