20 unique examples of light effect in graphic design
Light effects in graphic design are a way to give keenness to images creating a strong contrast between light and dark tones. These effects, an actual trend, give the best result when they are used in images really dark, so to highlight a particulate on which user attention should be attracted.
Some graphics, like Boss Logic and Pete Harrison, make lights and lightness a fundamental key for their works. What shall be considered using these elements is that light effects create shadows, areas to be made brighter and others to be made darker. It's not enough to download the picture of a lightness and set the layer to screen. Personally I like more light effects, even if used in an excessive manner.
Today I made a selection of 20 examples that can be used as source of inspiration for your next work:
