Gradient Black Headshot Backgrounds

I have three freshly shot, high-resolution headshots—one of me. one of my husband, and one of us together. All I need is a background swap: replace the current setting with a clean, professional black that carries a very light, center-outward gradient. For my headshot, please remove any flyaway hairs, and fix my hair on the bottom left side. For my husband headshot, leave his body and face completely untouched and only edit the background. For the picture of us together, please edit my nailpolish and perhaps my under eye bags so they’re not that visible.
Otherwise, Please leave our faces, clothing, and body contours completely untouched; the retouch should mainly affect the backdrop.

You may use Photoshop, Affinity Photo, or an equivalent pro-grade editor as long as the final files retain full resolution and look seamless when zoomed in at 100 %.

Deliverables
• 3 high-res JPEGs (sRGB) with the new gradient black background
• 3 layered PSD or TIFF files so future tweaks remain possible

Acceptance Criteria
• Background reads as pure black (#000) at the edges, feathering smoothly toward a slightly lighter tone around the subjects
• No halos, color spill, or sharp masking lines when viewed on a calibrated monitor
• Facial features, skin tone, clothing texture, and overall crop remain exactly as in the originals

Once you confirm, I’ll send the RAWs or full-size JPEGs right away. Looking forward to seeing your clean, professional touch.
