TIPS | Graduated Neutral Density filters?

What is a Graduated Neutral Density (GND) filter? How would I use one?

GND filters are a square or rectangular filter.

They are 50% dark grey, and 50% clear.

The dark grey half will reduce the brightness over the area it is positioned, whilst maintaining an exposure for the clear part.

GND filters are useful for sunset photography as they darken out a bright sky…
