simple black & white


#1

In photoshop 5.5, how do I export a color picture black & white?


#2

image->mode->grayscale.

Do it in a copy of the original before you accidentally hit “save” and loose the color version.

Beware: grayscale jpegs don’t show up in internet browsers.

You could also use image->adjust->desaturate. Since it’s not really grayscale, wouldn’t those show up in internet browers?


#4

yes offcourse, or convert it to grays and than back to rgb again :wink:

Another method:

Convert to lab color
Select Lightness channel
Duplicate Lightness channel into a new document
Convert this document to grayscale

The difference is not big, but converting this way results in a somewhat better conversion to grayscale (especially with flesh tones).

Grayscale images do show up in the browser (at least in mine :slight_smile: ), and they are smaller too. CMYK images certainly do not show up in the browser…

Another method, and one which allows you to do a lot of fine tuning, is to go to Image --> Adjust --> Channel Mixer and select the “monochrome” option. This way you can really spend hours balancing how the individual channels contribute to the final grayscale.

My mistake :wink:

My favorite method:

  1. Add a Curves Adjustment Layer and leave it alone.
  2. Add an HSB Ad-Layer and bring Sat all the way down.
  3. Go back to Curves Ad-Layer and play with individual channels to manual adjust contrast.

Great trick. Works wonders for converting fleshtones to greyscale.
