Understand the choice
Use natural light when possible, show the label or brewing setup and keep your own notes beside the image. Check the background for addresses, order numbers and other personal details before uploading.
Put it into practice
Upload photographs you own or have permission to use. Captions should say what was photographed, including any older equipment version. Do not use a generic landscape as proof of a specific farm or cultivar.
Keep the conversation useful
Share your actual recipe or experience, identify the coffee or equipment and explain what changed. A clear question with measurements makes the discussion easier for others to answer.
