Muslin Backdrop vs. Chroma Key Paint
Chroma key can use a muslin backdrop or green paint to create a space that can be shot against. A professional green screen studio is a room that is painted green. There are benefits and advantages to using muslin or paint. Which is best will entirely depend on your circumstances and budget. As long as the material is being used properly, then a professional effect can occur.
There is special paint manufactured specifically for chroma key. The vast majority of the paint is green, though it is also available in blue. These two colors are used frequently because they are most different from skin tones. For chroma key effects, only chroma key paint should be used. This special paint is completely matte and will not reflect any light.
Light reflection is one of the biggest problems with chroma key. Normal paint will have many different green shades within the one color. Chroma key will only have 1 shade. This paint is typically expensive but worth the extra cost.
Green muslin backdrops are frequently used for screens when only a small background needs a green screen effect. Muslin can be great the first or second time you use it. However, when the screen is washed, it will shrink and become wrinkled. Muslin is one of the best fabrics to use because it does not have a sheen and will not reflect a lot of light. Ironing can take care of any wrinkles. Additionally, this fabric is strong enough that it will not move should a breeze blow.
It is also very easy and inexpensive to build your own screen. Muslin can be found at a local fabric store, and all the supplies needed to create the backdrop are at the local hardware store. Muslin is frequently only found in a white or cream color. To get the right color, then painting muslin with a chroma key is a great option. This produces a great backdrop that can easily be moved to get the most out of your studio space. This is a great way to get the best from chroma key paint and a backdrop.
Chroma key is used to replace a backdrop with an additional image. The actor will be filmed standing in front of the green screen. In post editing using software, the green color will be replaced with another image. Anything that is the green color of the background will be replaced with the new image. Therefore, it is best to ensure that the costumes do not contain any green, or if green is used, then it's a very different shade.
Using Green Screen
Green screen is normally associated with movies and effect shots. They can be used by professionals and amateurs alike. However, many photographers are using green screen behind portraits. While it is possible to build or create your own green screen, it is also possible to rent a green screen studio or backdrop. Renting can be a good option for those that do not use this backdrop often. Much of what you will use will depend on your circumstances and budget.
