If you’re projecting onto a dark surface, like a burgundy stage curtain or a black wall, darker colors won’t be visible. Even making the image slightly smaller can significantly increase brightness. As a rule of thumb, by shrinking the projection size to half, you gain four times the brightness. To brighten your image, try moving the projector g closer or zoom out to achieve a smaller image. Fortunately, there’s a simple solution for increasing brightness. It’s sorely disappointing when your projection is too dark to see. Glass gobos also help ensure a higher quality image that stays true to your original design. Stick to bold block lettering and remove any unnecessary design components like filigree. The best solution to this problem is to simplify your design. This means it can become very difficult to make out small details, even with a strong projector. ![]() The uneven surface easily distorts delicate patterns. These are both common issues with uneven surfaces as well as large-scale projections. Why are the details of my gobo getting lost in the final projection?Īre smaller lines and patterns blending into the rest of the image in your final projection? Or perhaps your cursive lettering is difficult to read. This is challenging, however, because it requires your gobo manufacturer to know your exact setup (including the projector’s projection lens, distance from the projection surface, and elevation) to calculate the geometry. We call this process keystone correction. Most gobo manufacturers can also pre-distort the image on the gobo in the opposite direction to correct for the angle. If you can’t raise the projector, try increasing the distance to reduce the angle and minimize distortion. When you’re projecting from a sideways angle, however, the opposite is true. When your projector is positioned at an upward or downward angle relative to the projection surface, a landscape format artwork will appear less distorted than a portrait format. If you can raise the projector closer to the level of your projection, your image will be less distorted. The steeper your angle of projection, the more distorted the image becomes. So how can you avoid this image distortion? Often, however, you’re forced to set-up the projector at ground level, resulting in an effect called keystone distortion. Sometimes, you can place your gobo projector perpendicular to the projection (for example in the window of an adjacent building). Often, outdoor projection surfaces are high above the onlooker’s vantage point, like a cliff-face or skyscraper. ![]() Below are some of the most common gobo projection questions answered by our projection specialists. Common image projection challenges (and how to fix them)įor most uneven surfaces, there are a few common projection challenges you need to overcome to achieve a bold, crisp image. To help you expand your marketing canvas, we’ve answered your most common gobo projection questions about working with nontraditional surfaces. Each of these surfaces, however, is not without its challenges. It can also make a bold statement to project an image onto water, or other unexpected surfaces like a cliff face or a tree’s foliage. While a flat surface ensures the crispest image, clearly visible from multiple angles, you don’t always have an untextured, or even solid, surface to work with. Part of the fun of gobo projections is that you can display an image on almost any surface.
