Love the look of a black and white image presented in among the chaos. Makes it stand out like calm in the clutter.
By why is this so? What diverts our attention to focus on this feature? Is it the crispness of the outlines, the attention to detail within the image, or the sheer delight in the contrast of only two colours (non colours)? Does it make us immerse deeper into the subject? Are we spellbound and captivated by the content? Can we read the visual message quicker? It could be all of these things, or it could just be because it is different. It stands out.
And so we stare.
Consider this use within the social media space. A difference, the contrast is noticed. Use it wisely. Use it well. Bring on the spell.
