A computing device obtains a digital image of a color calibration target for a product; obtains product information for the product; determines image adjustment information based on the digital image of the color calibration target; obtains a digital image of the product based on the image adjustment information; and transmits the image data of the product and the product information to a backend product computer system. Obtaining the product information for the product may include scanning a graphical code, such as a QR code or a bar code, or obtaining information from the product via short-range radio-frequency communication. The method may further include receiving a response from the backend product computer system, which may include additional product information. The color calibration target and encoded product information may be included in a QR code having three or more color regions.
