In this section you will also find the Baby Bop costume for toddlers. White materials are usually the best choice for when you have good control over the room lighting - for example if you are showing the screen in a basement with no outside lighting coming in the room.You may also select a Barney and Friends BJ Costume for toddlers. Grey materials are designed to provide higher picture contrast by lowing the black levels in the projected image. The colors are not as bright as they would appear on a white screen, but grey screens are great for making black in the projected image appear darker and is a great choice for rooms that have some ambient lighting present, since the additional contrast helps overcome image "washout" that happens when unwanted ambient light hits the screen. Our matte grey material does tend to look more dull than our matte white, simply because of the grey tint on the material - but there is very little color shifting since our factory keeps the tint in the grey range so that the colors themselves do not shift toward blue, red, or any other color shade. If you have good light control and you are looking for brilliant colors, then you should most likely choose matte white. It is by far our most popular screen material we sell because most people like the way it performs. If you do not have good light control or your projector does not have a lot of contrast, then you may consider matte grey. Some people use their projection screen at night to watch movies. Because the viewing of movies is mainly at night a white screen would be perfect for most situations. You may watch sporting events during the day. Sporting events are very bright and do not have deep black scenes during the game. Sporting events look fantastic on a white screen with some light in the room. Stenghths: Brighter colors and good reflectivity. Weaknesses: Washout more likely in cases of uncontrolled and ambient lighting. Strengths: Increased ability to retain black level in cases of uncontrolled and ambient light. Weaknesses: Slight loss in brighter colors. Grey screens can be grey or high contrast screens. Adding a shade of grey to a projection screen material will lower the white levels and black levels equally. A high contrast screen will add the shade of grey but also be a little reflective. With the shade of grey the black levels are deeper, but with the extra gain or reflectiveness the white levels don't drop as much. This makes the levels of contrast higher than what a white screen can do. The grey projection screen material will absorb ambient light because any shade other than white begins to absorb light. A grey screen will absorb some of the light that hits it or reflects onto it better than a white projection screen. The goal of a grey screen should be to offer better contrast for most projectors. In some projection applications a screen with a shade of grey may be better because the projector is too bright for the size of screen being used in a dark room. In rooms that are not completely dark a grey screen begins to have its advantage. Projector and screen manufacturers recommend a white screen in completely dark rooms (unless the projector is too bright for the screen size and will light up the room). As the room gets lighter and lighter the darker the shade of grey the screen material should be.
