How to photograph a sick plant for a diagnosis

Three photos are enough: the whole plant, the worst leaf up close, and one more angle. Shoot in daylight, keep the shots sharp, and include the pot and soil — that's most of what separates a confident diagnosis from a guess.

The three shots

1. The whole plant. Step back far enough that the whole plant and the top of its pot are in frame, in daylight, without backlight. This shot carries the species ID and the overall pattern — which leaves are affected, and where on the plant it starts.
2. The worst leaf, up close. Fill the frame with the most affected leaf, sharp and evenly lit, with both the damage and some healthy tissue in view. Edges, spots, and undersides are where causes separate from each other.
3. One more angle. The next most useful thing: the soil surface, the stem base, or the underside of an affected leaf. If the soil looks constantly damp or the base looks dark or soft, this is the shot that shows it.

Lighting and framing tips

• Daylight beats lamplight — indirect window light shows leaf color honestly, and color is evidence.
• Avoid backlight (a bright window behind the plant turns it into a silhouette).
• Hold still or lean on something; a blurry close-up hides the detail that matters.
• Include the pot: drainage, pot size, and soil surface are part of the diagnosis.
• Photograph the plant as it is — don't remove damaged leaves first. The damage is the chart.

Why photos change the answer

Plant Doctor's confidence tracks photo quality. Clear, well-lit shots of the whole plant plus a close-up of the worst leaf give the best results; when confidence is low, the app says so and suggests a better angle instead of bluffing.
