What Lightsmith does

Lightsmith (Beta) is Radbin's live light studio for Adobe Photoshop. It reads your photo once (its depth, its shape and where the subject ends), then computes studio light on it in real time, on your own computer. No AI model redraws the picture, so everything the light does not touch stays exactly as shot. Start from a setup built round the face it finds, such as Rembrandt, Low key or Backlight, or from one for products (Three-point, Spotlight) and rooms (Window light, Golden hour, Evening lamps, Night). Then drag the lights, move them in front of or behind the subject, and give each one a modifier (softbox, beauty dish, grid, snoot), a colour temperature, a gel and a softness. Your own setups can be saved, and they land round the face on the next photo too. Trying lights is free. Applying a result costs 2 credits and places it as one layer, or as one layer per light.

How it works

1Open a portrait, a product shot or a room in Photoshop. Select an area, or nothing for the whole image
2On the Enhance tab, find Lightsmith and click Open the studio. Pick a setup, then drag the lights and change their modifier, colour and softness
3Click Apply. The light lands as one layer, or one layer per light, and one undo removes it

Questions

Lightsmith, answered.

Is Lightsmith generative AI?

No. AI reads the photo once, to measure its depth, its shape and where the subject ends. The light itself is computed live on your computer and no model redraws your picture, so faces, skin and detail stay as shot.

Which Photoshop do I need?

Photoshop 2025 (26.0) or newer, on macOS or Windows, and an active Radbin plan, like the other Enhance tools. The rest of Radbin runs on Photoshop 23.3 and newer.

Does it work on products and rooms?

Yes. Lightsmith tells a portrait from a product or a room by itself, or you can choose. Products get setups like Three-point and Spotlight; rooms get Window light, Golden hour, Evening lamps and Night.

How long does it take?

Reading a photo takes a few seconds, and up to half a minute for the first one after a quiet spell. After that the lights move live.

What lands in my document?

One layer with the new light, or a group with one layer per light so you can fade each light on its own. One undo removes it all.

How is it different from Relight?

Relight chooses the light for you and an AI model relights the whole scene in one click. Lightsmith hands you the lights: you place each one and see the result before you spend a credit.
