<p>Look into film emulator plugins, such as VSCO, which you can use with photoshop, lightroom, or on your phone and get one click results, or search for film emulation tutorials for photoshop if you want to do it yourself. There are many different ways to achieve that type of look but much of it can be done using curves and levels on the individual RGB channels to get the color scheme you want as well as to get the contrast and faded look, then desaturate it to taste.</p>
