Yousuf Karsh was a photographer who captured portraits of prominent 20th century figures from various fields. He aimed to capture their emotions and poses in an off-guard manner to create more interesting, storytelling images. Karsh typically photographed his subjects up close to draw attention to their facial and bodily expressions, without including much background scenery. This allowed viewers to focus on the subject and imagine the context. His portraits used techniques like medium shutter speeds and rule of thirds to create depth and interest. While the images have less definition due to the era in which they were taken, this adds character relative to more defined portraits.
