THE IMAGE QUALITY WORKSHOP

Your 4K AI Image Has Three Hidden Tests

A café hero-image workshop that separates more pixels from a picture you can actually use.

A beautiful café image can look finished in the chat window and fall apart the moment you put it on a website. The cup disappears behind your headline. The pastry turns into an impossible knot. The wide crop cuts off the one thing you wanted people to notice. More pixels will not repair those decisions.

How Jennifer Aniston’s LolaVie brand grew sales 40% with CTV ads

For its first CTV campaign, Jennifer Aniston’s DTC haircare brand LolaVie had a few non-negotiables. The campaign had to be simple. It had to demonstrate measurable impact. And it had to be full-funnel.

LolaVie used Roku Ads Manager to test and optimize creatives — reaching millions of potential customers at all stages of their purchase journeys. Roku Ads Manager helped the brand convey LolaVie’s playful voice while helping drive omnichannel sales across both ecommerce and retail touchpoints.

The campaign included an Action Ad overlay that let viewers shop directly from their TVs by clicking OK on their Roku remote. This guided them to the website to buy LolaVie products.

The campaign helped drive a big lift in sales and customer growth, helping LolaVie break through in the crowded beauty category.

THE SHORT VERSION

Build for the final layout first. Then check the downloaded file, inspect the important details, and try the actual crop. Today’s brief gives you one café image and three clear reasons to keep it or start again.

Give the image a real job

Imagine a small coffee shop needs a homepage banner for its morning menu. The image has to feel warm and appetizing, but the left side also has to hold a dark headline. That makes a pale, quiet background valuable. A spectacular composition packed with props is less useful if there is nowhere to put the words.

Use the prompt below in an image tool you already have access to, such as ChatGPT or Gemini. Choose a landscape format in the interface if that control is available. This is an original practice brief, so the business does not need a name, logo or invented customer. Keep the scene simple enough that every visible object earns its place.

Know what the 4K label tells you

Google’s current Gemini image documentation includes 4K output for supported models through the API. That is a specific capability, not a promise that every Gemini interface, mode or download uses the same dimensions. Read the settings in your actual tool and inspect the downloaded file’s width and height in its properties.

Also keep resolution and quality separate in your notes. Write the pixel dimensions on one line and the visual defects on another. A larger file can still contain melted cutlery or a misshapen cup. If you enlarge a smaller export later, record that step instead of treating it as a newly generated native-resolution result.

COPY THE CAFÉ BRIEF

Create a landscape editorial photograph for a small café’s morning-menu homepage. One cream ceramic cappuccino cup on a matching saucer sits in the right half of a pale limestone counter. Place one clearly formed butter croissant behind the cup and one folded oatmeal linen napkin beside it. Warm window light enters from the right. Show a believable contact shadow, a clean cup rim and a simple heart in the milk foam. Keep the left 40 percent of the frame pale, calm and largely empty so a dark headline can be added later. Use natural food texture and a welcoming morning atmosphere. Show the complete cup and saucer, with comfortable space around them. Avoid people, signs, lettering, logos, cutlery, extra pastries, fog and dramatic lens effects. Create one finished image, not a collage.

Run the three tests

First, open the file at 100 percent and inspect the cup rim, saucer edge and croissant folds. Look for broken curves, duplicate edges and detail that dissolves into decorative noise. Do not reject natural softness in the background. Judge whether the objects that carry the story remain believable.

Second, place the image in a temporary banner and add the real headline in your layout editor. View it at phone width. If the text needs a dark box just to become readable, try a quieter left side before adding more design. Third, crop a square version. Can it still tell the café story without awkwardly amputating the cup?

Keep the original download, the final crop and one sentence about the most useful correction. For this exercise, success means a credible coffee scene with usable headline space and a clean secondary crop. The winning image is the one that survives its job. A resolution label is only one item in that decision.
