The D610 was first supported by Camera Raw 8.3 which is only compatible with Photoshop CS6 or later.

- Join the CCPP, or
- Free: download the free Adobe DNG converter, convert all Raw files from the D610 to DNGs then edit the DNGs in CS3
Photoshop Help | Digital Negative (DNG)
That explains why the RAW plug-in doesn't work!
However, as mentioned above CS3 won't recognise DNG files either.
How can I get round that?
Are you using the DNG 8.3 converter or later versiom?
I'm at work right now and will need to check at home this evening - I think it's the 8.3, which is the only one I could see.
Do I need the later version for CS3?
Many thanks so far
