There are many different ways to emphasize the "focal point"
Change the colour of what you want to emphasize:
This is a good representation of using colour to create a focus point. The model's skin and the background don't compete with the neon pink lips which is why it the first thing the viewer looks at. This technique is good because it is simple and direct.
Yes these "art" principles and elements do apply to typography.
Without the colour you might have read shoulder x4
^ thought it was kinda cute.
Use framing to draw attention to your subject.
J'ADORE. J'ADORE. J'ADORE.
This photo both FRAMES the model and uses the makeup tools as LINES to draw attention to her face and EMPHASIZE her makeup. (did i really just put all those important words in one sentence >? YEESS !)
which brings me to the next point...
Use of lines - to both create more interest and create "focal point" !!!
Lines do not have to be literal. The rocks on either side of the model serve as lines to both FRAME and draw the readers attention.
Play with PROPORTION
at least for this picture... KANYE IS THE MAIN SPOTLIGHT. sorry taylor swift :P
PLAY WITH SHADOWS...
Nothing is made more important than THE HAIR in this picture...although, I could do with out the visible jeans though...but thats for another day...MOVING ON !
I have no doubt in my mind that there are probably better examples or more points... but thats for you to figure out - not my issue.
THE MAIN THING IS REMEMBER ABOUT EMPHASIS IS:
BE DIFFERENT AND STAND OUT
BE BIG & BE BOLD
GO HARD OR GO HOME!!!
