An Image That Fits the Layout
Centred hero shots are the default and the wrong shape for real work. Specify canvas, placement and named empty space.
What it is for
Front-loads the decisions a layout imposes — canvas shape, subject placement, and empty space described as a real surface — so the generated image survives being placed. Use it for anything going into a banner, a cover, a slide or an ad with copy over it. It prevents generating nine good pictures that all have to be cropped through the subject.
The skill
The default is a centred, symmetrical, dramatically lit hero object. That is a fine picture and the wrong shape for nearly every job it will be used in, because you need somewhere to put words and a frame that fits the slot. Decide three things before you write a word of the prompt: 1. Canvas shape — square, wide or tall — chosen from where the image will live, not from what looks good in the chat. Cropping a square into a banner later removes exactly the part you wanted. 2. Where the subject sits and how much of the frame it fills. "The subject occupies the right third; the left two-thirds is open sky." State the fraction. "Off to one side" is ignored. 3. The empty area you need, described as part of the picture rather than as an instruction: "a wide expanse of flat, evenly lit wall across the top half with no detail in it." That is something it can draw. "Leave room for text" is not. Also state these, because otherwise the default decides for you: - Camera distance in plain words: wide establishing shot, waist-up, macro. - Eye level, or it drifts to a heroic low angle. - Depth of field, if type has to stay readable over the background. - Whether anything may cross the frame edge. Objects touching the edge break the moment the image is cropped for a second placement. Test it where it will be used, at the size it will be used. Nine images viewed at 40 percent of their final size all look acceptable. If it still centres the subject, describe the empty side FIRST and the subject second. Order changes what gets built around what.
How to install it
1. Open the tool and start a new conversation, project or template. 2. Paste the text below wherever the tool keeps standing instructions — usually called system prompt, instructions, or persona. 3. Save it so it applies to every run rather than a single message.
