Godox AD-S9 Snoot Overview:

• It can converge the light to a smaller lighting area, highlighting the details and reaching a transitional nature.
• Both can be used in combination in producing a clear boundary of the shadow.

• Model: Godox AD-S9
  Concentrates light in a small area and highlights product details. Border areas fade into the dark. Good for shooting ear rings, watches, glasses, mobile phones, etc.What is a snoot ?A snoot is just a funny name for a piece of equipment, generally a tube or similar objects such as a conical, cylindrical, or rectangular shape, that fits over a studio light or portable flash. It allows you to control the direction or area of coverage of the light. Basically, it makes the light more focused and concentrated by directing your light and focusing it. This makes the coverage very narrow and the light falls-off very sharply giving you a harsher or harder light.
• Adding a Grid
  Personally, I like the snoot and grid combo because it produces a very tightly controlled beam of light, which comes can come in handy in certain shots. It’s great for moody or editorial shoots and in a pinch can function as a hair light. The grid also softens the light by making into many small lights instead of single-point source and that makes it a little more gentle. A grid and snoot are some of my favorite things to have on hand. I love using it as a hair light for a portrait session.
