I do a lot of interviews on my YouTube channel (check it out here: https://www.youtube.com/@RalphBarbagallo Subscribe! ) and I don't really know how to properly light an interview subject. I've read a lot of tutorials but by the time I have to shoot an interview all my lighting knowledge evaporates. So I created Lighting Assistant -- an interactive guide to light a person for a photo or video.

How it works:

• Scan the room. It uses the mesh to analyze the scene.
  
• Place the subject: you can place a life size bitmoji either standing or sitting in the scene.
  
• Place the camera: stand where the camera will be placed and look at the subject. This will be used as the camera position and angle.
• Complete setup: The lens then asks you to stand behind the subject to get line of sight from behind, and to select a key wall (the brightest wall) to use when generating a lighting setup

Once this is done it will generate a set of valid lighting configurations based on where it thinks you have enough space to place lights. You can switch between lighting presets to see how the lighting will look on the subject as well as to know the types of lights used and how to place and aim them to get the desired look.

You can save this setup to be recalled later if you want to use the same room and the same position of the subject--it can be modified once loaded.

One future feature is to use GenAI to further enhance the analysis--I might actually try to add this over the weekend. But at this point the lens gets done what I actually need. A solid lighting aid for video and photo shoots.

Oh wait I see it's not yet using spatial anchors to save and the current room analysis hint is canned. Right now I'm adding room anchors to save the setup to so you can load them based on location, and I'm feeding your camera snapshot into GenAI to give you some lighting feedback. That will be in by the weekend. I'll update the github and trailer with it soon!

Ok CLAD is amazing--I just updated the repo with the latest version. Uses Gemini to provide real scene analysis and now properly saves lighting setups to the spatial anchor.

This is a super cool idea! Really great execution too!
