I was watching a video and in the background, the guy was demonstrating his photoshop skills in a timelapse. I am trying to figure out how he achieved this particular blending effect. I went frame by frame through the video but it is just too fast. I included a photo of the image before and after. I spotted that he was using "blend layer" and "color overlay". Could someone explain to me or point me in the right direction as to how to achieve this particular effect. Note the original image is on the right.
