Retra LSD Ultimate

Embrace light. Admire it. Love it. But above all, know light. Know it for all you are worth, and you will know the key to photography.

The Light Shaping Device is made for your underwater flash.

The Light Shaping Device (LSD) works like a projector which takes light from your flash and pilot light to create a beam with a sharp image at the focus distance. The LSD uses elements like a lens, mask and a diffuser to generate the light beam.

It's easy to use even on your first dive!

By turning on the pilot light you can see accurately how the image will appear before you press the shutter button. This way you can quickly find the right position for your LSD and start shooting.

You can shape light, sharpen it's edges or make them blurry.

Left image is with the light beam focused. The focus point is at 175mm from the edge of the LSD (in water!). Right image is with the light beam slightly out of focus. 

Illuminate two spots with the double hole mask.

Illuminating two spots was a mission impossible, with the LSD it's easy! You have to insert the double hole mask and find the right distance between the holes. Positioning is a breeze because you have the pilot light to show you where the projection will be.

Use the LSD for creative lighting. 

The strong directional and collimated beam of the LSD is perfect for playing with the position of your flash relative to the subject. Use it for side lighting or back lighting. 

Illuminate larger areas in wide angle.

The powerful LSD can also be used for wide angle shots. This is especially interesting once we get closer to the subject. 

If you change your flash, you only change the mounting module. Every LSD is made from two modules: the Optical tube and the Mounting module. They are connected via four screws and can be exchanged in a few minutes.
