Painting outdoors on this shore means working against two clocks at once. The sun moves the shadows, and the tide moves the subject: a bar of sand that anchored a composition at the start of a session can be under water before the session ends, and the light bouncing off that water changes with it. Shoreline painters answer with short sessions, small panels and a palette decided before the first mark goes down.

This section documents those habits instead of prescribing them. What a field kit holds once it has to be carried over soft ground. How a session window is chosen, and what happens to the plan when the wind gets up. Why the gray half of the year teaches faster than the bright half. Tide predictions for the Maryland shoreline are published by NOAA Tides and Currents, and these pages send readers there for the numbers rather than repeating them second hand.
