Newbie color qustion

Post by masmit »

Hi, I'm new to ImageMagick in particular, and image processing in general. I apologize for what may be a foolish question:

I'm using Magick from the command line on a Mac OS X G4 laptop, and what I'm seeing is that many of the magick filters seem to be altering the colors of images when I wouldn't expect them to.

For instance, using the median filter with a radius value of 4 on a photo image, the blurring effect is what I expect, but the image is left with a marked overall blue tint. If I apply the median filter to the same iamge in Photoshop Elements - I get the same blurring effect, but no blue tint.

Is there a setting I need to make to avoid/correct this?

Many thanks for any help,

Mark

We do not see this problem. Could your input image have a color profile?

I'm afraid I really am a newbie at this - how would I find out if an image has a color profile?

Thanks,
