Elf color corrector is a tool that helps to make the colors in your image more accurate and natural. It works by correcting the color tones, shadows, and highlights to match the original colors. You can use elf color corrector in two ways - by adjusting the sliders on the right side of the app or by using the eyedropper tool. The eyedropper tool allows you to select a specific color and automatically adjusts the other colors to match it. You can also apply different filters and effects to your image for a more creative look.
