AI poster from your photo: a bold black-and-white manifesto poster
By GetStepSnap · Tested October 8, 2026
Black-and-white portrait in the middle, sliced repeats of it fanning out behind, a lot of white space, one bright block of color and a headline set heavy enough to shout. It's the look of a campaign poster, and this prompt makes it from an ordinary photo.
We wrote the template and ran it through Nano Banana 2.1 with a selfie, a street snapshot, a cat and a pair of shoes. Each result is the first one we got at 1K, resized and nothing else. The starting photos were made with the model, so no real person appears here.
The prompt
Fill in the subject, a headline of a few words and a short subtitle. With your own photo, put "Use the person in this photo as the subject and keep their face exactly the same." in front.
A manifesto-style poster about [your subject]. The subject, shot close, fills the center and lower part of the frame: a restrained, frontal pose seen slightly from below, with quiet dignity, cleanly cropped at the edges, holding a strong first-glance gaze. The background is bright, airy white space. Behind the subject, several tall narrow slices split off like image columns cut with a sharp blade, each showing part of the same subject (texture, outline, expression or a key detail) at different sizes and staggered heights, repeating, overlapping and crowding the figure in front. Behind the subject sits one block of saturated accent color taken from the subject's own mood, material or culture, used only as a small spark and anchor. Everything else is a clear light base, a dark main figure, a muted support layer and clean information color: bright, clear, calm and strong, with clean shadows and fine grain that never looks dirty. The headline "[HEADLINE]" in extra-bold sans-serif capitals sits under the subject, slightly overlapping the body, with the subtitle "[SUBTITLE]" in narrow uppercase as a tight band below it. It should look like high-contrast black-and-white photography, cut-paper collage and minimal ad layout in one, keeping the tension between the repeated slices, the central figure, the bright white space and the one accent color.
Four posters and the prompts behind them
BE YOURSELF
Use the woman in this photo as the subject and keep her face exactly the same. A manifesto-style poster about being yourself. The subject, shot close, fills the center and lower part of the frame: a restrained, frontal pose seen slightly from below, with quiet dignity, cleanly cropped at the edges, holding a strong first-glance gaze. The background is bright, airy white space. Behind the subject, several tall narrow slices split off like image columns cut with a sharp blade, each showing part of the same subject (texture, outline, expression or a key detail) at different sizes and staggered heights, repeating, overlapping and crowding the figure in front. Behind the subject sits one block of saturated accent color taken from the subject's own mood, material or culture, used only as a small spark and anchor. Everything else is a clear light base, a dark main figure, a muted support layer and clean information color: bright, clear, calm and strong, with clean shadows and fine grain that never looks dirty. The headline "BE YOURSELF" in extra-bold sans-serif capitals sits under the subject, slightly overlapping the body, with the subtitle "YOUR VIBE. YOUR STORY. YOUR WAY." in narrow uppercase as a tight band below it. It should look like high-contrast black-and-white photography, cut-paper collage and minimal ad layout in one, keeping the tension between the repeated slices, the central figure, the bright white space and the one accent color.
Her face, the slices, an orange block and both lines of text spelled right. The headline sits in a white band below her. She smiles instead of the cool stare; ask for "a serious, steady look" if you want that.
STAY CURIOUS
Use the man in this photo as the subject and keep his face exactly the same. A manifesto-style poster about curiosity. The subject, shot close, fills the center and lower part of the frame: a restrained, frontal pose seen slightly from below, with quiet dignity, cleanly cropped at the edges, holding a strong first-glance gaze. The background is bright, airy white space. Behind the subject, several tall narrow slices split off like image columns cut with a sharp blade, each showing part of the same subject (texture, outline, expression or a key detail) at different sizes and staggered heights, repeating, overlapping and crowding the figure in front. Behind the subject sits one block of saturated accent color taken from the subject's own mood, material or culture, used only as a small spark and anchor. Everything else is a clear light base, a dark main figure, a muted support layer and clean information color: bright, clear, calm and strong, with clean shadows and fine grain that never looks dirty. The headline "STAY CURIOUS" in extra-bold sans-serif capitals sits under the subject, slightly overlapping the body, with the subtitle "ASK MORE. BUILD MORE. LEARN MORE." in narrow uppercase as a tight band below it. It should look like high-contrast black-and-white photography, cut-paper collage and minimal ad layout in one, keeping the tension between the repeated slices, the central figure, the bright white space and the one accent color.
It picked a deep blue for curiosity on its own. The white headline band runs across his lower body, and his T-shirt shows again below it.
NAP HARDER
Use the cat in this photo as the subject and keep it looking exactly like this cat. A manifesto-style poster about a cat who takes naps seriously. The subject, shot close, fills the center and lower part of the frame: a restrained, frontal pose seen slightly from below, with quiet dignity, cleanly cropped at the edges, holding a strong first-glance gaze. The background is bright, airy white space. Behind the subject, several tall narrow slices split off like image columns cut with a sharp blade, each showing part of the same subject (texture, outline, expression or a key detail) at different sizes and staggered heights, repeating, overlapping and crowding the figure in front. Behind the subject sits one block of saturated accent color taken from the subject's own mood, material or culture, used only as a small spark and anchor. Everything else is a clear light base, a dark main figure, a muted support layer and clean information color: bright, clear, calm and strong, with clean shadows and fine grain that never looks dirty. The headline "NAP HARDER" in extra-bold sans-serif capitals sits under the subject, slightly overlapping the body, with the subtitle "SUN. SILENCE. SOFT BLANKETS." in narrow uppercase as a tight band below it. It should look like high-contrast black-and-white photography, cut-paper collage and minimal ad layout in one, keeping the tension between the repeated slices, the central figure, the bright white space and the one accent color.
Works for pets too. The headline covers the bottom of the cat's body. In black and white the orange tabby turns gray; the mustard block brings back a little of its warmth.
RUN YOUR CITY
A manifesto-style poster about a pair of white running shoes. The subject, shot close, fills the center and lower part of the frame: a restrained, frontal pose seen slightly from below, with quiet dignity, cleanly cropped at the edges, holding a strong first-glance gaze. The background is bright, airy white space. Behind the subject, several tall narrow slices split off like image columns cut with a sharp blade, each showing part of the same subject (texture, outline, expression or a key detail) at different sizes and staggered heights, repeating, overlapping and crowding the figure in front. Behind the subject sits one block of saturated accent color taken from the subject's own mood, material or culture, used only as a small spark and anchor. Everything else is a clear light base, a dark main figure, a muted support layer and clean information color: bright, clear, calm and strong, with clean shadows and fine grain that never looks dirty. The headline "RUN YOUR CITY" in extra-bold sans-serif capitals sits under the subject, slightly overlapping the body, with the subtitle "EARLY MILES. EMPTY STREETS. NO EXCUSES." in narrow uppercase as a tight band below it. It should look like high-contrast black-and-white photography, cut-paper collage and minimal ad layout in one, keeping the tension between the repeated slices, the central figure, the bright white space and the one accent color.
A product with no photo at all. The headline sits below the shoes. It added the word "manifesto" and a line of tiny made-up text at the bottom; crop it or ask for "no other text".
Tips
- Short headline, short subtitle. Two or three words read best at this size; the subtitle works as three short sentences.
- Ask for the look you want. Our people smiled. For the cool, steady stare of a campaign poster, add "a serious, steady look into the camera".
- Choose where the headline goes. The prompt asks for it to overlap the body slightly. On the man and the cat it crossed the lower body; on the woman and the shoes it sat just below. To decide it yourself, try "the headline sits below the figure" or "the headline overlaps the lower half of the body".
- Watch for small print. The shoe poster got the word "manifesto" and a line of tiny made-up text at the bottom. Add "no other text", or crop it.

Questions
Can I turn my photo into a poster with AI?
Yes. Attach one clear photo, start with "Use the person in this photo as the subject and keep their face exactly the same," then paste the template with your headline and subtitle. In our tests the face, the cat and the text all came out right on the first try.
Will the headline be spelled correctly?
In all four of our posters, yes: BE YOURSELF, STAY CURIOUS, NAP HARDER and RUN YOUR CITY, plus every subtitle. Keep the headline to a few words and put it in quotes.
Can I choose the accent color?
The prompt lets the model pick it from the subject: it chose orange, deep blue, mustard and blue for ours. To set it yourself, replace "one block of saturated accent color" with "one block of red" or any color you want.
What shape should the poster be?
3:4 is a classic poster and fits a phone screen well; all four of ours are 3:4. Choose 2K if you'll print it; it still takes 1 credit.
How much does it cost on GetStepSnap?
Your first 1K image is free. After that a poster takes 1 credit at 1K or 2K, and 100 credits cost $9.90 (plus local tax where it applies), about $0.10 each. No subscription.
