The most important things to pay attention to when applying makeup for photographs:
Contour of the cheeks – In my opinion, this makes the most impact in a photograph. Highlighting bone structure is key! Your cheeks will not look as dramatic in pictures as they do in person.
Lip liner – The trick to a perfect pout is lip liner. For pictures I use a different shade lip liner to blend into the lipstick shade; almost like an ombré lip. Gives the perfect pop to any look.
Highlighter – A lot of people bypass this step, I’ve made it part of my foundation routine when doing any type of makeup. In photos, highlighter can make your face look completely different by effecting the way that the light is hitting your face. I heavily highlight the cheekbones (above your blush) and the t-zone of the face.
