He is wearing a blue t-shirt and is holding a chalk in his right hand. On the chalkboard, there is a mathematical equation written in white chalk. The equation reads "Power dissipates of a rate and a distance". The man appears to be giving a presentation or explaining the equation.</caption><caption><image_176>The image shows a man standing in front of a green chalkboard. He is wearing a blue t-shirt and is pointing towards the chalkboard with his right hand. On the left side of the image, there is a blackboard with white chalk writing on it. The writing on the blackboard appears to be a mathematical equation or problem. The man seems to be explaining the equation to the viewer.</caption></video> twice the distance right it has to travel from the ring to the marker and then from the marker to the camera so you have double the distance so one possible improvement is to just put the light directly on the markers right if i can directly light the markers i've cut the distance in half right so that means i should be able to move the markers further away and get the same amount of brightness in the camera if i don't mind putting batteries or whatever i need or this has to be plugged into a separate source if it's
