At first, I really loved this image, but I realized I hadn’t perceived it correctly. I thought it was one photo with two different color schemes, but it turns out to be two separate images: In the upper photo, it's the sea and the sky, and in the other one, we see the man looking at the sea as well, but in black and white.
The thing is, I keep seeing them separately; to me, those two photos aren't really merging into each other; they don’t seem to share the same concept that would unite them.
In this ad design, I would change just one small thing to suit my taste: I would crop out the sea in the upper photo. I can explain what difference this detail could make: it would create a different association.
Now it's as if the man were looking up at a different world, a different sky above him, where he sees something new and fresh—something that has not yet been seized (and the two different color schemes make us perceive the duality of the worlds). Maybe that other world seems far away, but there's something for him up there, in the blue sky, and that's the type of association I would like to create.
Below I made 3 slightly different versions without the sea in the upper picture, and the photo of the sky can also determine the specific mood that we might've wanted to convey, but I think the overall concept would be infused together better this way. It starts with one and ends with another without breaking the flow in the photo, if you will.
Now it gives me a slight association (though not exactly) with 'The Wanderer Above the Sea of Mist' by Caspar David Friedrich, but in this case, it would be an actual sea instead of the sea of mist as a metaphor.
I'm sure the original design had a different intention to convey than the one I am talking about, but since I saw a different potential in what else it could have meant by altering small details, I decided to share my point of view as well and lead the idea in my own direction.
