We've colourised three archival photos this year and each time a client pushed back saying it felt made-up. Diagnose where our colourisation process loses authenticity, and recommend one research habit and one restraint rule I should adopt so future colour references honour the original photo and still support the campaign's palette.
when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

How to do it

The tool
Generative Fill

Generative Fill uses AI to add, expand, or remove content from your images based on text prompts.

  1. 1

    Open your image by selecting File > Open.

  2. 2

    Select the area you want to transform using a selection tool.

    Best practiceFor expanding the canvas, use the Crop Tool to extend the image boundaries first.

  3. 3

    Click the Generative Fill button in the Contextual Task Bar.

    NoteYou can also access it from Edit > Generative Fill, or Select > All then Edit > Generative Fill.

  4. 4

    Type a prompt describing the object or scene you want to generate in the text-entry field.

    NoteYou can leave the prompt field empty to have Photoshop generate content based on the surrounding image.

  5. 5

    Click Generate.

  6. 6

    Review the generated variations in the Properties panel.

  7. 7

    Select your preferred variation from the options.

  8. 8

    Save your image by selecting File > Save As or File > Save a Copy.

Generative Fill creates new content on a separate generative layer, allowing non-destructive edits.

Generative Fill functionality is integrated within Photoshop and is not directly exposed as a standalone API for external automation.

Questions people actually ask

with the jobs and tasks they touch

Sometimes, the AI-generated pixels don't have enough detail or proper blending, causing print quality issues at large scales.

Always review your extension at 100% zoom to see if the AI blended pixels smoothly. Fix any rough edges or mismatched areas before printing.

Use the 'Match Evening Mood' or 'Replace Sky' tools to better blend the extension with the original image. Adding subtle color adjustments helps too.

Relying on the AI to perfectly blend without manually checking or refining the extension can lead to visible seams or mismatched areas in large prints.

A photo editor or retoucher doing large-scale prints will notice these failures during final proofing or print setup.

AI can create a convincing extension, but for large prints, manual touch-up or blending is often needed to ensure quality at final size.

Yes, it's related because both involve creating or blending new pixels, but generated extensions focus on AI inventing missing parts for printing.
