Is there a plugin or function in QGIS that allows for RGB raster color adjustments to enhance visibility of specific features captured on a map?
I'd like to enhance contrast and saturation of high resolution orthomosaic to make drainage system (below the soil) more visible and easier to vectorize. Output raster is less saturated (but better color balanced) than original photos from which was made so it makes harder to spot all lines.
It can be obviously done in i.e. Photoshop but due to file size limitations and potential loss of georeferencing I prefer to use QGIS for that.
