Do anyone know how to make a ortofoto brighter? The ortofoto I am currently working on is a bit to "dark" lake it`s taken in the evening.

Try RGBBrightnessContrastAdjuster from the FME Hub

Thank you :)

If you want to learn more about manipulating raster pixel values yourself, I'd recommend starting at this very helpful article that demonstrates several use cases for the RasterExpressionEvaluator: https://community.safe.com/s/article/simple-examples-using-the-rasterexpressionevaluato
