Culling

Keep the sharp one. Numa knows which it is.

Came home with four hundred frames? Numa measures the sharpness of every one, groups your bursts and points at the best frame of each. It asks whether someone's eyes are closed, and puts two frames side by side at the same magnification when you can't decide.

Clipping

Swipe up to pick, down to reject. Stars, flags, albums and smart filters for the rest.

Masks

The sky, your subject, a person. In one tap.

Numa looks at the photograph and offers what it finds: sky, subject, person, water, greenery. Tap one and it's a mask — with its own light, colour, curve and grade. Click a thing to add it, subtract what you don't want, or draw your own with a brush, lasso, linear or radial mask, or a colour or brightness range.

The models run on your device. Your photograph goes nowhere.

Colour

Colour you can trust, and looks you can dial.

Camera profiles make a RAW look like your camera meant it; lens corrections straighten what the glass bent. For Fujifilm, profiles fitted against the camera's own JPEGs. Then make it yours: Numa's looks come with a Strength slider, a grade wheel for shadows, midtones and highlights, a colour mixer, and your own LUTs (.cube, .3dl).
