Flat design is quite popular, at least, the style has been for several years. Flat style serves as a counter to skeumorphism, a design style meant to mimic the real world in the digital space. Flat graphics emphasize typography and content, and are often employed in UI designs so as not to distract users from important functions.
While flat aesthetics have their place, they’re often criticized as lacking depth. Since flat style eliminates depth-perception elements, such as shadows, the designs may appear lifeless or boring to some. I made this digital illustration of my Nikon FM10 35mm film camera to show that flat design can have depth using tones and shades instead of gloss or shadows. I used Adobe Illustrator to create this vector art piece. I hope you see that flat graphics needn’t lack depth entirely.
