Brighten Artwork Photo for Print

I photographed one of my paintings, but the background came out slightly shadowed. I need it taken to a moderately brighter level so the final image reproduces accurately when I send it to the printer.

Alongside the light adjustment, please remove any visible blemishes—dust specks, tiny marks, or camera artifacts—so the piece looks pristine up close. All colours and brush-stroke textures must stay true to the original work; no heavy filters or stylistic changes, just precise retouching.

Deliverables:
• Print-ready file at the image’s full resolution (JPEG or TIFF)
• Correct colour profile embedded (sRGB or Adobe RGB)
• A brief note on the steps you took so I can reference them later

I typically work in Photoshop, so keeping the layers intact in a PSD copy would be a bonus, but it isn’t mandatory. Looking forward to seeing the artwork shine.
