ToolBox lenses
Five ToolBox lenses for reading a source.
The homepage shows one example from each lens.
In ArtDeck, each lens contains several tools you can adjust over the same source.
Color
Extract a palette, map temperature and saturation, and inspect how color is distributed.
Composition
Overlay grids, test a crop with the viewfinder, check symmetry, or make a thumbnail sheet.
Read
Squint, group large shapes, map detail density, and reveal the edge hierarchy.
Measure
Place plumb lines, read an angle from three points, and compare two lengths as a ratio.
Non-destructive studies
ToolBox leaves the source unchanged.
Save a snapshot back to the board or export it when you want a separate study.
