Getting the best results from your rock identifier depends largely on how you photograph your specimens. Here are photography tips for optimal rock identification.
Lighting is the most important factor for rock identifier accuracy. Natural diffused daylight provides the most consistent results for the identification algorithm. Mid-morning or late afternoon light tends to show rock features without harsh shadows or glare.
Your rock identifier performs best when the rock fills most of the frame. Get close enough that the stone occupies at least 70 percent of the image. This gives the algorithm maximum data to work with for accurate identification.
Clean surfaces make better rock identifier subjects. Dirt, moss, and lichen obscure the features that the identification algorithm uses. If possible, clean the rock surface before photographing it for your rock identifier.
Multiple angles improve rock identifier accuracy significantly. Take photos of different rock faces, especially a freshly broken surface if available. Many rock identifier apps including Wonder Rock allow you to provide multiple images for more thorough analysis.
Moisture affects how a rock identifier sees a rock. Wet rocks appear darker with more saturated colors, while dry rocks show their true texture. For initial identification with your rock identifier, photograph dry surfaces when possible.
Background matters less than you might think for a rock identifier. The algorithm focuses on the rock in the foreground. A neutral background helps, but do not stress about it. Your rock identifier is designed to ignore background distractions.
Follow these photography tips and your rock identifier will deliver more accurate identifications on every outing. Good photos equal good results.
