Why photographers switch
- No subscription. One price per year, no matter if you edit 5,000 or 500,000 photos. Nothing renews automatically.
- Your clients’ data stays on your PC. No uploads, no cloud – important for GDPR and for your clients’ trust.
- Built by a wedding photographer. ConstantLight was developed by a full-time wedding photographer for his own workflow of 40–50 weddings a year.
- Works with Lightroom Classic. ConstantLight writes standard XMP settings – you keep full control and can fine-tune everything in Lightroom.
How it works
- Choose the folder with your Sony RAW files.
- Pick a style – or let ConstantLight learn your own from finished Lightroom catalogs.
- Click “Apply style” – the Constant AI agents even out exposure image by image.
- In Lightroom Classic: select all → Metadata → Read Metadata from Files. Done.
