Lumen Tool vs set.a.light 3D: which one is right for you?

I occasionally see people arrive at Lumen Tool after searching for set.a.light 3D.

That makes sense. Both tools let you experiment with lighting before you build the real setup, so from a distance they can look like alternatives to each other.

They do overlap, but they are built around very different ideas.

So instead of trying to argue that one is “better”, I wanted to put the two next to each other and make the difference clear. If set.a.light 3D is the better tool for what you need, you should use set.a.light 3D. If Lumen Tool fits your workflow better, then that is what you should use.

The point is simply to know what you are choosing.

The main difference

The shortest explanation is probably this:

set.a.light 3D is a complete virtual studio for photo and film. Lumen Tool is a fast lighting workspace.

With Lumen Tool, you open the site and the simulator is already there. There is a head, there is a light, and you can immediately start moving it.

Change the angle. Raise it. Move it closer. Make it softer. Add Fill, Back or Hair Light in Studio. The result changes immediately.

There is almost nothing between opening the site and actually experimenting.

set.a.light 3D takes a much broader approach. It lets you build complete 3D sets, position models, add furniture and props, choose lighting equipment and modifiers, work with cameras and lenses and plan much more of the final production.

That gives it considerably more scope.

It also means you are working in a much larger piece of software.

Lumen Tool is built around speed

This is probably the biggest strength of Lumen Tool.

There is no installation. You do not need to download a large asset library. You do not need to create a room, choose equipment or prepare a scene before you can start looking at light.

Open the page and move the light.

For a portrait photographer, videographer or someone setting up a talking-head shot, that can be the entire point.

You may simply want to answer questions such as:

• What happens if I move the Key Light further to the side?
• Is this closer to Loop or Rembrandt lighting?
• How much Fill do I want?
• Would a Back Light help separate the subject?
• How does the setup change on a different face?

That is the kind of work Lumen Tool is designed to make very fast.

set.a.light 3D is built around the complete shoot

If your question is bigger than the lighting on the subject, set.a.light 3D becomes much more interesting.

You can construct an environment, add props and furniture, position people inside it, work with a large range of virtual photographic equipment and plan camera positions as part of the same scene.

That means you can use it for much more detailed pre-production.

If you are planning a commercial shoot, a complicated studio setup or a scene where the environment matters just as much as the person, that extra control can be extremely useful.

The Cinema side goes even further into moving cameras, models and scene elements.

Lumen Tool does not try to do that.

What Lumen Tool does instead

Lumen Tool puts nearly all of its attention into the lighting workflow itself: building a setup, comparing it, and keeping it around for later.

The Lighting Simulator lets you build and compare setups around different heads. Studio adds multiple lights, different views, setup diagrams, comparisons, exports and saved setups.

Reference Lab approaches lighting from the opposite direction: you start with a portrait, and it analyses the visible lighting to give you a suggested starting point for the simulator.

The Archive then gives you a place to keep setups, comparisons, photos and notes together and reopen them later.

So while set.a.light 3D expands outward into the entire virtual production, Lumen Tool expands around the process of understanding, developing, comparing and keeping lighting ideas.

Real equipment and exposure

There is another important difference.

set.a.light 3D contains a large library of photographic lights and modifiers and goes much further into physical equipment and exposure simulation.

If you want to work around particular lights, modifiers and measured exposure behaviour, that is one of its major strengths.

Lumen Tool takes a more general approach.

It does not pretend that moving an intensity slider to a certain value means your real flash should be set to exactly the same number.

Your real exposure depends on the actual lamp, modifier, power, room, camera and subject.

Instead, Lumen Tool concentrates on the visual relationship between the lights and the subject: direction, distance, softness, colour, contrast and shadow shape.

The idea is to arrive at the real shoot already knowing roughly where the lights should be and what they should be doing, then fine-tune the actual output with the equipment in front of you.

The learning curve is different too

Lumen Tool is deliberately difficult to get lost in.

Most controls are visible immediately and the relationship is straightforward: move something and look at what happens.

That makes it useful not only for planning shoots, but also for learning lighting in the first place.

set.a.light 3D gives you far more things to control. For someone who needs those controls, that is a major advantage. For someone who only wants to explore portrait lighting for ten minutes, it may be far more than necessary.

Neither approach is automatically better.

It depends entirely on what you are trying to do.

Side by side

That table probably explains the difference better than anything else.

Which one should you choose?

If you want to build complete virtual shoots, work with specific equipment, construct sets, add props, position models and cameras and plan a production in detail, set.a.light 3D is probably the stronger choice.

That is exactly what it is built for.

If you mainly want to understand and plan lighting around a person, experiment quickly, compare ideas and keep those setups without installing another large application, Lumen Tool is probably the better fit.

That is exactly what I built it for.

There is also no reason the two could not exist in the same workflow. Someone could use set.a.light 3D for detailed production planning and still use Lumen Tool when they simply want to test a portrait-lighting idea quickly.

They solve overlapping problems, but they do not solve them in the same way.

Try it yourself

The easiest way to know whether Lumen Tool makes sense for you is simply to open it.

The basic Lighting Simulator is free and does not require an account, so you can see within a few minutes whether the workflow suits you.

If you want the additional lights, heads, setup tools, Reference Lab, the Archive and the other Studio modules, you can see what is included in Lumen Tool Studio.

And if what you really need is complete virtual set building and detailed equipment simulation, set.a.light 3D is likely the more appropriate tool.

Choose the one that actually makes your work easier.
