This guide will help teach you everything you need to know about using green screen and digital backdrops in Simple Booth HALO.<\/p>\n\n\n\n

Good To Know<\/strong>:<\/strong><\/b> The terms “green screen” and “chroma key” are often used interchangeably. However, there is a nuanced difference.

Chroma key<\/em> refers to the process of removing a color and leaving a transparency that can be replaced with something else. Green screen<\/em> refers to the same thing, but suggests only a green color. We call the feature Chroma Key in Simple Booth apps because Simple Booth supports either green or blue<\/em> for the background.<\/p>\n\n\n\n

Gather your green screen equipment<\/strong><\/h2>\n\n\n\n

To use the Chroma Key feature in Simple Booth HALO, you\u2019ll need the HALO app and an active subscription<\/a>. We also recommend using HALO hardware,<\/a> but it’s not required. HALO hardware features a large, soft light source that smooths out shadows from the backdrop.<\/p>\n\n\n\n

Aside from that, you’ll need a few additional items for a flawless green screen experience. Let’s go over those now: <\/p>\n\n\n\n

Use a green or blue backdrop<\/h3>\n\n\n\n

Simple Booth HALO supports either a green or blue screen, the choice is up to you. We recommend using the traditional green screen backdrop in most cases.<\/p>\n\n\n\n

The reason we recommend green is because green contrasts more with skin tone than blue, so it tends to get a cleaner image. To achieve a seamless green screen effect, the color of the background needs to contrast with the subjects in the photo. <\/p>\n\n\n\n

Also, people are typically less likely to be wearing green than blue\u2013unless it’s Saint Patrick’s Day or the Green Bay Packers are playing! With that in mind, we’ll be referring to the physical backdrop as a “green screen” from here on out.<\/p>\n\n\n\n

Lastly, when shopping for a green screen fabric or paper, check to make sure it is wrinkle-free for the best results. The green screen needs to be as pure green and bright as possible. It also needs to have a matte finish, not shiny or glossy.

Source a quality mounting system<\/h3>\n\n\n\n

You\u2019ll need a way to mount your green screen that will stand tall for as long as you need. This is commonly done by stretching the green screen fabric across a set of aluminum stands.

The stands in the photo above can be purchased directly from Simple Booth. They are stable, portable, easy to use, and will give your activation a professional look. <\/p>\n\n\n\n

In some cases, you may be able to mount a green screen directly to the wall. If so, ensure the fabric is stretched taut enough to keep it completely flat without any wrinkles or drooping fabric.

Lighting is key to green screen results<\/h3>\n\n\n\n

One reason Simple Booth HALO is popular for green screen is because its large luminescent ring light eliminates hard shadows that can be problematic for green screen. HALO users don\u2019t typically need any extra lighting for green screen. <\/p>\n\n\n\n

However, if you\u2019re only using HALO app without HALO hardware, you will definitely require additional lighting. In that case, we suggest adding fill lights on both sides. Your environment and the time of day can make a big difference in the lighting that will be required to get quality images.<\/p>\n\n\n\n

Find backdrop images<\/strong><\/h2>\n\n\n\n

It’s not hard to find photos online, and you can use just about any JPG or PNG as your digital backdrop, but make sure that you have the proper rights or license to use an image. This is especially true for businesses using images for commercial use.<\/p>\n\n\n\n

In some instances, you may need to purchase a license to use an image. Luckily, there are a few sites in which professional quality images can be found free of charge for commercial or personal use. <\/p>\n\n\n\n
