How to create AI images: a beginner’s guide

To create an AI image, decide what the picture needs to communicate, describe the scene in plain language and choose a model. Set the format, generate a first version and check it against your brief. Improve one problem at a time instead of repeatedly changing everything.

Open Deepnia Image and choose Nano Banana 2 to follow the method step by step.

You do not need a long list of technical phrases to begin. You do need a clear purpose and a way to recognize a usable result.

1. Decide where the image will be used

Start with the destination: a blog cover, social media post, presentation or product page. Those are different design jobs. A blog cover should make the topic easy to recognize. A product image must accurately represent what someone would receive. A presentation background needs enough quiet space for readable words.

Write a one-sentence brief before opening the generator: “I need a warm café image for a social post announcing a new seasonal drink.” Then identify the one thing that must stand out. In this example, it is the cup, not the furniture or the view outside.

Choose your intended crop at this stage. If you will later add a headline, decide where it will sit. Leaving space deliberately is easier than trying to squeeze text over a busy image. Keep important objects away from edges that may be cropped on another screen.

2. Choose text generation or a reference-based workflow

Text is a sensible starting point for an invented scene. A reference image may be more appropriate when you need to preserve a particular object, face or arrangement. These are not interchangeable requirements: asking for “a red bottle” does not identify your actual bottle. Deepnia Image accepts reference images for both generation and editing.

Use an image you are entitled to upload and modify. Remove unrelated private details, and keep an untouched original. For this exercise, a fictional cup is enough; there is no need to use a customer photograph. Write down which details are flexible and which must remain unchanged.

3. Turn the brief into a visible scene

Describe what someone could actually see: the subject, setting, framing and light. “Make an amazing professional picture” leaves almost every important decision open. “An ivory ceramic cup on a wooden table beside a window” gives you something concrete to evaluate.

Add only the details that help your purpose. A crowded shelf, several pastries, a newspaper and a vase might all be attractive, but together they can compete with the drink. For a first exercise, simplify the scene rather than asking the generator to solve a complex layout.

Example prompt:

Create a photographic-style image for a fictional café announcement. An ivory ceramic coffee cup sits on a warm wooden table beside a window. Frame the cup on the left, with clear empty table space on the right for a headline added later. Use soft morning light and a restrained cream-and-brown palette. Keep the setting simple. Do not include lettering or logos.

For readable lettering, see readable text in AI images.

4. Choose the format and the model

Choose the aspect ratio in the Deepnia Image settings. Asking for “vertical” in a prompt describes your intention, but it is not a substitute for checking the actual output settings. Each generation returns one image; Seedream v5.0 Lite Sequential returns a series of 1–15.

Then pick a model, such as Nano Banana 2, GPT Image 2 or Nano Banana Pro.

5. Judge the first result against the job

Look at the image at its intended display size first. Can you immediately recognize the subject? Does the composition leave enough room for the message? An image can look beautiful at full size yet become confusing in a small social preview.

Then inspect details more closely. For the café image, examine the handle, rim, liquid surface, shadow and contact with the table. Look for repeated or disconnected shapes. Do not mistake a polished photographic style for evidence that the scene is physically plausible.

Use three decisions: keep, make one targeted correction, or change the approach. If the cup is convincing and the headline space works, another generation may not add value. If the cup is malformed, fix it with an edit in Deepnia Image rather than regenerating everything.

6. Make a focused revision

Suppose the first image has a good cup but a busy background. Your next instruction should name that problem and protect what already works:

Keep the cup, its position and the warm window lighting. Simplify the background to an uncluttered café interior with no decorative objects competing with the cup. Preserve the empty area on the right.

Apply it as an edit to the existing image in Deepnia Image. Starting another text-only generation may produce a different composition. Keep the previous version so you can compare rather than relying on memory.

Avoid changing the cup, camera angle, colors and background in the same revision. If the result improves, you will not know which change helped. If it gets worse, you will have several new problems to diagnose. A small written revision log makes the process easier to repeat.

7. Prepare the image for its final destination

Download the selected output and inspect the exported file. Check its dimensions, crop and appearance in the actual layout. Do not approve it solely from a small preview inside the generation interface. A headline added later can change how balanced the composition feels.

Give the file a meaningful name, such as “fictional-cafe-coffee-window-light,” rather than leaving it as an unexplained sequence of numbers. Keep the prompt and model information with your project notes.

If the picture represents a real offer, separately verify the product, wording and any figures you add. For a real product, start from its photo in Product Shooting for packshots and lifestyle scenes.

Your first-image checklist

• I know where the image will appear and what it must communicate.
• I have one clear subject and a suitable crop.
• My reference material is appropriate to upload, if I use any.
• I have chosen a model and a format.
• I have inspected both the overall composition and small details.
• I have reviewed the exported file in its final layout.

Frequently asked questions

Do I need to know how to draw?

No. For this workflow, the useful skills are describing a scene, choosing priorities and spotting mistakes. Drawing knowledge can help, but a clear brief and careful review are enough to start practicing.

Will the same prompt always produce the same image?

No. Save the output you like and record the settings you used. If consistency matters, add a reference image or see keeping a character consistent.

Which AI image model should I start with?

Open Deepnia Image and start with Nano Banana 2; if the image must contain text, use GPT Image 2. For a matching series, choose Seedream v5.0 Lite Sequential.
