Make the cleaned imagery safer for automated feature extraction by running a mild noise reduction that preserves edge contrast, combine with a selective curve lift in shadow bands, and export a 100% crop for the analyst to confirm no faint features were lost in denoising.

Retouching Tools

Photoshop's Retouching Tools help you fix imperfections, remove unwanted elements, and enhance details in your images.

    In the Layers panel, select the layer containing spots or objects to remove.

    RecommendationDuplicate your image and make layers to avoid permanent changes.

  2. 2

    In the Tools panel, select the Spot Healing Brush tool.

    NoteLong press on the Spot Healing Brush to reveal other tools like the Clone Stamp.

  3. 3

    In the Options bar, set the brush Size and other parameters.

    Best practiceUse Spot Healing Brush tool modes like Lighten and Darken for specific adjustments.

  4. 4

    Click or drag over the area you want to retouch.

    NoteThe Spot Healing Brush automatically samples surrounding pixels.

  5. 5

    For more control, select the Healing Brush tool from the Tools panel.

  6. 6

ActionsRecorded series of commands that can be played back to automate repetitive tasks in Photoshop.ExampleYou can record a set of Photoshop actions to apply the same effects to many images.
LayersStackable, transparent sheets that hold different elements of an image, allowing independent editing.ExampleYou place a text layer above a background image layer, so the words appear on top of the picture.

Questions people ask

honest answers

Because you rarely think 'I want the redaction tool'. You think 'I have to share this without leaking the client's details'. Start from the need, and the feature finds you.

Real. Every job here was drawn from what people in real roles were actually seen doing in Photoshop — not a feature checklist.

No. Each page gives you a ready prompt you can paste into an AI assistant, plus the plain steps to do it yourself. Start with either — the goal is the finished job, not the tool.
