Clean Up Outdoor HEIC Photo

I have a single iPhone-shot HEIC image that I need manually retouched in Photoshop—absolutely no generative-AI tools, plugins, or filters. Between three and five people have to disappear from the scene, and the area they occupy is an outdoor, natural background (grass, trees, sky, a few distant objects). After removal I want the environment reconstructed so no trace of editing is visible, preserving natural light, colours, and texture continuity.

Deliverables
• High-resolution, flattened HEIC (and a JPEG for preview) with all edits applied
• Layered PSD showing your non-destructive workflow

I will review the file at 100 % zoom; seamless blending and zero artefacts are required for approval.
