Do
- Use neutral, consistent lighting
- Keep the original file unchanged
- Record broad location, date, species and crop stage
- Use a hygienic scale reference only when safe
- Note sensor position and calibration status

How to photograph a crop problem
One close-up is rarely enough. Capture pattern, scale, a healthy comparison and environmental context—without contaminating the crop.
6-photo technical set
- 01
Whole room or bed
Establish the scale and distribution of the problem before moving closer.
- 02
Affected rack and layer
Show the exact rack, layer or bed zone and its relation to airflow and work paths.
- 03
Affected cluster
Record the affected group without selecting only the most dramatic specimen.
- 04
Close-up with colour fidelity
Preserve colour and morphology; avoid filters and exaggerated saturation.
- 05
Healthy comparison
Use the same stage and similar lighting so the comparison is meaningful.
- 06
Relevant sensor or equipment
Include the reading, position, time and unit—not only the instrument display.
Do not
- Apply colour filters
- Stage symptoms or move contamination
- Expose faces, plates, addresses or client boards
- Name a disease from colour alone
- Submit precise GPS unless intentionally required
