Hello

 

I have some Colour images that I wish to make Black and White on Pages or using Preview.

 

How do I do this?

 

Thankyou,

 

Peter

    You can change them to appear B&W, but they will stay color no matter what in both Pages and Preview.

     

    Open them in ColorSync Utility > None > Output > Black & White > Save As > TIFF > compressed or otherwise

     

    Do not click on Apply. That will change your original, very unMac behavior.

    Thankyou Peter.

     

    I'm assuming that I can changer the colour then save as the newly created BW version.  Correct?

     

    Cheers,

    It does what it says.

     

    The filter converts your files to grey scale images strictly on the black plate.

     

    You need to save it to .tiff because .jpegs, pngs etc are all .rgb.

     

    You could save to .pdf as well and it would retain its black plate, but pdfs are well nigh impossible to determine their native resolution and color mode without doing extensive tests. Best to keep it where you can manage, control and determine what the file is.

     

    TIFFs can also be tinted in Pages, which would once again make them cmyk.

    Once again , thankyou Peter.

     

    I did, however have a play in Pages and found a much easier method.

     

    Copy and paste the jpeg image into Pages, then go to Image Browser (?) reduce the tint to zero and the image is now black and white. Press save as new.

     

    Cheers,

    I did warn you that is not black and white.

     

    It is rgb that looks like black and white.
