error converting photo to grey

[nowen3]

Im trying to convert a colour photo to greyscale. The command im using is

convert "c:\photo.jpg" -colorspace Grey "c:\photo1.jpg"

the convert command keeps returning this error

Magick: unrecognized image colorspace `Grey' @ error/convert.c/ConvertImageCommand/993.

I've tried this on linux and windows and with a number of images and get the same results.

Try Gray

Also check "convert -list colorspace" next time.

Thank you very much. I feel so stupid making a silly mistake like that
