Event agency seeks photo software

We are an event agency and are looking for new photo software – photos only, no videos – for cropping photographed people. We offer photo services and event photography, e.g. for trade fair appearances, promotional campaigns, children's birthday parties, or company celebrations. Our service portfolio also includes galleries and reviews.

The software should meet the following requirements:

• Green screen
• with different layers, e.g. foreground, background, overlay
• Subsequent editing (e.g. effects, retouching)
• Color and black and white
• Add text
• Various settings (keys)
• Save projects (including layers)
• Image must be imported into the software
• Export (e.g., for emails, printing)
• Runs on a MacBook with macOS

One software workstation is planned.
