Step 2<\/strong>: Follow your chosen projection distance down the column for the desired projection size. This is the diameter of the projected image and is typically between 3 and 8 feet for indoor projection and 6 to 40 feet for outdoor projection.<\/p>\n Step 3<\/strong>: Select a projector (aka your Model in the chart) that shows your desired image size with sufficient brightness. The brightness or illumination values are the colored rows (green to red) directly beneath the gray image size. Note that each color represents a different level of brightness based on the type of environment you plan to project in. See Diagram 1 below for examples of which levels of brightness are for which environments.<\/p>\n Diagram 1:<\/em><\/p>\n Before we go through a detailed example together using the chart, let\u2019s look at three examples of projection variables and what type of lens you would need for each.<\/p>\n \n Long distance projection<\/strong><\/p>\n For projecting a gobo over large distances you’ll need the right projector first, but you’ll also need to use a lens that projects a tight, narrow beam between 5 and 15 degrees. This is best for use at outdoor festivals or events where you want to shine a gobo image on a building or landscape in the distance.<\/p>\n Short distance, large image<\/strong><\/p>\n Indoor uses, such as theater stage projection or at a club, require a completely different approach. You’ll have a broader range of projectors to choose from, but you’ll need to select a lens with a much wider beam angle, typically higher than 20 degrees.<\/p>\n Brightness<\/strong><\/p>\n How bright you want your image to appear will also factor into the lens angle, not just the bulb and projector used. The further the distance, the larger the image and the darker the projection. The image size has a huge impact on the resulting brightness. For example, if you double the projection size by doubling the projection distance, you end up with only a quarter of the brightness. Likewise, if you need a brighter projection, move the projector closer or use a narrower lens.<\/p>\n <\/p>\n Let\u2019s look at three different lighting environments and figure out what lens you would need for each scenario to project an image that\u2019s approximately 6 feet across from a projection distance of 18 feet.<\/p>\n For the first example, let\u2019s say I need to project a logo onto the inside wall of a dimly lit cocktail bar. If we look at our projection chart, we can see an option for 18 feet under projection distance. If we follow that column down, we see quite a few options for projecting an image with a diameter of 6 feet. To narrow down our options, we need to think of our environment: a dimly lit bar. According to Diagram 1<\/a> above, we should be looking for orange under the brightness row which leads us to the below combo:<\/p>\n Best lens option<\/strong>: 70mm lens combined with the ES-LED10 projector for 11fc brightness. (Note that this lens has a beam angle of 15 degrees which is just within the optimal beam range for long-distance projection noted above).<\/em><\/p>\n We now are in a much brighter environment, so let\u2019s start with our projection distance (18 feet) and look down the row in search of a 6 foot diameter image size that\u2019s yellow, according to Diagram 1<\/a>. In the restaurant, you need to switch lenses and projectors for optimal brightness:<\/p>\n Best lens option:<\/strong> 100mm lens with the ES-LED-B40 projector for 43fc brightness.<\/p>\n When you have a space with large windows and lots of natural light, you\u2019ll need to increase the brightness of your image for it to stand out. For this environment we\u2019re looking for the color lime-green:<\/p>\n Best lens option:<\/strong> 140mm lens with the ES-LED-B90 projector for 202fc brightness.<\/p>\n As you can see, depending on the environment you will need different lenses, and in some cases different projectors, to achieve the desired effect for your gobo image.<\/p>\n Ready to order your lens?
