Image note
Three original interpretations of salt-water edges & mineral crusts, informed by Le Lac Assal. These images explore material and spatial ideas; they are not documentary views or measured reconstructions of the reference. The palette is drawn from the material portrait.

Artwork recordThree views of one material idea.
Lake Assal is a saline lake in central Djibouti, documented in the country’s UNESCO tentative-list submission. Its landscape offers a study of mineral deposits, water and sharply changing surfaces.

The edge where reflection stops
Lake Assal offers a sharp material contrast between water and mineral crust. One surface can return a broad reflection; the other breaks light into many small changes. The transition is more useful to study than an isolated white sample detached from the lake.
02 / From surface to space
Read the whole.
Then the edge.
A shoreline can be simultaneously a clear boundary in plan and a gradual change at close range. Compare the broad curve with the fine structure along its edge. The difference between scales prevents the white mineral band from becoming a purely graphic stripe.
Compare a salt crust’s fine texture with the broad edge of the lake. Study the transition from reflective water to a dry mineral surface.
03 / Colour in context
A palette you can work with.
Five tones drawn from the material portrait. Select a colour, compare it on paper and ink, or copy its value into your own study.

Make the observation tangible.
Place a matte, granular sample beside a smooth reflective plane. Light both from the same direction and observe their edges. Keep the palette interpretive and retain the source’s tentative-list status in any factual description.
Keep a view of the whole beside a close detail. Note the material, lighting and the one variable you changed.
