Looks great but ... blue? Is the Nex5 only sensitive to OIII or something?

Looks good Philip, a bit more processing and it will be a ripper, looks like the OAG is a good set up for you.

Hi Chris,
Have had little time to try processing in photoshop , this image was processed in DSS only. The nex5 does seem to have a blue bias , will try processing in ps and resubmit image. Am between two houses at present and finding it difficult to find time.
Thanks for the comment regards philip
