We're very excited to finally reveal Helios Pro for cinematographers and photographers. Not only can you pinpont the position of the sun, the moon (and now) stars the way you can in Helios, we've also added Augmented Reality and light simulation magic into the alchemal mix. Now you can visualize exactly what shots will look like at any location, at any time of the year or day. You can see precicely how light will illuminate and the shadows will fall.


For landscapes we create a dynamic 3d mesh of the surrounding terrain and show how the light will change throughout the day across the hills, mountains and valleys.

For city photographers we download OpenStreetMap building data and render a 3d reconstruction of the buildings and streets. You can therefore see exactly how the light will strike the buildings throught the day.


New to Helios Pro are a number of tools to help with night photography. The new milky way section gives you three different ways of visualizing the stars at any location. It also includes a unique night-shoot planner designed to let night photographers plan Milky Way photography.

- Multiple tools to explore sun, moon, and star data.
- Light simulation on a range of virtual stand-ins.
- Scarily accurate alchemy and celestial mechanics.
- Night-shoot planner to see the optimum dates and times to shoot the Milky Way.
- Dynamically generated 3D models of landscapes, buildings, cars, trees (and of course, a dinosaur).
- Many tools will still work without reception.
- Multiple ways to export data.
- iPad and iPhone compatible

An awesome tool for photographers, too!

I used the app to plan a natural light shoot for one of our agency’s largest clients, knowing I’d have little access to the location beforehand, and only a small window to capture content the day of, as we were paying by the hour for the space. With Helios Pro, I was able to time our shoot down to the minute, and plan for the positioning of all our subjects, bounces, and cameras with a scientific degree of accuracy. Needless to say, the lighting in every shot came out perfect, just as planned. Though it’s mainly marketed to cinematographers, I’d recommend this app to anyone hoping to capture consistently beautiful, natural light photography. 5/5 stars would buy again. Side note: the customer service is amazing.


Excellent except for the clunky saving of pictures.

I’ve just started using this and after two days of experimenting I find that the saving the photos option is too slow. It’s a three step process for some reason and when you’re out in the bright light it’s not easy to see all the buttons.

That aside the 3 D model in Live view is excellent. If you’re shooting a car commercial this is a must. It’s as accurate as sun seeker which is pretty accurate when using the compass, but not perfect. If you have the sun already out you can calibrate from that and then it is an excellent tool.

I just hope they figure out the saving of the photos part, it’s the only thing I’m not crazy about with Artemis view finder too.

It’s the only reason I didn’t give it five stars.


Gets better and better

I direct feature films for a living. I have done so for forty five years. Like the camera technicians I work with we all care deeply about how our movies look, and Helios has been helping us make them look their best for years. It just got even better! What a great update and well worth the money.
