Look at the frame
Notice the horizon, reflections and the edge of the water. Describe these in plain language. A beautiful image does not prove depth, weather, access or a local fishing result. Known circumstances belong in the caption; unknown ones should remain unknown.
Choose the picture carefully
One broad view and one different detail can be more useful than many near-identical images. Protect other people’s privacy when making your own photographs. For a borrowed image, keep the photographer, original page and conditions of use with the file.
Write two lines
Use one line for confirmed context and another for a personal impression. This simple separation keeps the note readable without inventing an experience. A photograph may inspire an outing, but practical decisions still require current information about the intended destination.
