TL;DR
What did u/Few-Profession421 use Gemini for?
A detailed prompt turns any uploaded landmark photo into one 3:4 poster: the real photo on the top half and a geometric illustration of the same building on the bottom half, with the skyline lined up across the middle. They shared several posters made this way, and commenters planned to try it or vectorize the results.
What they did
They upload a photo of a landmark and use a prompt that asks for one vertical 3:4 poster split into two equal halves. The top half keeps the photo with light color grading and no changes to the building. The bottom half redraws the same landmark from a few large shapes in a palette taken from the photo, with paper grain and a screen-print texture. The prompt also asks to line up towers and rooflines across the split and bans text, logos, borders and collages.

Using the uploaded photo of [landmark] in [city], make one 3:4 vertical poster split into two equal halves. Top half: the photo, with the building's shape, materials and light unchanged and only gentle color grading. Bottom half: the same landmark redrawn with a few large rectangles, circles, triangles and arches in colors taken from the photo, with subtle paper grain. Line up the main towers or rooflines across the middle. No text, logos, borders or extra landmarks.
