Part of my clientel are a number of garden photographers and as is known amongst this group that Canon cameras (unlike Nikon) tend to make green garden foliage a little too yellow.
Thankfully Adobe have released ACR 4.5 with better support for external camera profiles. If you have Photoshop CS3 and its fully up to date then download this beta profile I have made and put it in one of the following locations:
On Mac OS X:
On Windows 2000 / XP:
C:Documents and SettingsAll UsersApplication SupportAdobeCameraRawCameraProfiles
On Windows Vista:
The profile gives more accurate garden greens for the UK.
Download the profile here
Once the profile is copied, restart Photoshop and open a raw image taken on a mkII. Select the camera icon on the raw converter tab, then from the NAME dropdown select the profile.
Let me have any comments.
