A Lightroom developer is responsible for managing and editing digital images using Adobe's Lightroom software. They adjust parameters like exposure, contrast, and saturation to enhance photo quality, and use features like spot removal, radial filter, and upright tool for specific adjustments. They also organize images using the software's cataloging system, and may add metadata for easier searchability. They can create and apply presets to streamline workflow, and export the final images in various formats. Their goal is to ensure the final images meet the desired aesthetic and technical standards. They also troubleshoot any issues arising within the software.
