Questions

Can I edit RAW photos online for free?

Yes. Open your RAW file, develop it and export it. Editing is free; to save, create a free Culacc account or log in.

Which cameras are supported?

RAW files from Nikon (NEF, NRW), Canon (CR2, CR3), Sony (ARW), Fujifilm (RAF), Olympus (ORF), Panasonic (RW2), Pentax (PEF), Samsung (SRW), and DNG.

Is it like Lightroom?

LightCraft develops photos the same way: sliders for light and colour, curves, crop and masks, without changing your original file.

Are my photos uploaded?

No, not while you edit. They stay in your browser until you choose where to save.

LightCraft is new and gets better every week. For important work, keep a copy of your original file.
