📷 Camera

Marso has been designed and developed with professional & prosumer cameras in mind, such as DLSRs, mirrorless cameras, and some smartphone cameras.

If you are capturing with multiple cameras, they must all be the same model. Marso can only work with one camera model for each capture.

Ensure that you can

Save images in a Raw file format
Set manual exposure (shutter speed / ISO / Aperture)
Disable any image stabilization, either on the lens, camera or both.

Info
If shooting with an iPhone/iPad, the Halide Mark II - Pro Camera app is recommended to shoot in RAW.

A high aperture number will offer better results, by keeping more of the object in focus

See Supported RAW Formats.

🔎 Lens

We suggest use a lens around 28mm (wide). Marso requires the whole object be kept in frame.

Ultra-wide and telephoto lenses are not recommended, due to the increased distortion making a photogrammetry solve more difficult.

💡 Light(s)

Usually the best option for lighting is the on-board flash, either on your DSLR camera or smartphone. If you don’t have an on-board flash, or wish to use an existing light setup, see External Light Sources.

Capture Scene

Ambient Lighting

Ideally the scene would have no ambient light at all. Failing this, the flash must be powerful enough to overpower any ambient light

Background

In addition to reducing the ambient lighting, it is also important to reduce any bounced or reflected light. This is quite easy to do by ensuring that you are shooting against black, or by avoiding too much white in your surrounding area.

Markers

Markers are recommended to improve the accuracy of the photogrammetry solve.

Marso also requires the solved scene to be accurately scaled, so it is a good idea to have at least two markers and measure the distance between them, as this can be used to scale the scene.
