What are the best setting to use to correct shadows especially ones cause by bright backlight.. Some photo software has a shadow adjustment slider.

Thanks

All high-end colorists and their tools use a combination of lift and gamma to correct for this, normally push the controls in opposite directions -- such as increasing gamma while reducing lift. We don't have a shadow fix function, or a high light recover has you might see in LightRoom or other photo tools (most video CC tools don't have those,) but those functions can all be achieved though the Primaries corrections control panel in FirstLight.
