Converting to Black and White



There are three way converting your shot into black and white using photoshop.
  • Grayscale (go image>mode>grayscale)
  • Channel mixer (go image>adjustment>channel mixer)
  • Desaturation (go image>adjustment>Hue/saturation)
Grayscale
The Grayscale method is a straight away change the image into B&W by just
simply clicking on the grayscale button.This is the simple way of turning your
photos into B&W.But not much adjustment you can do when using grayscale.

Desaturation
This method also similar with Grayscale but not so very straight foward as the
grayscale way. By using the slider on the saturation. Slide it to the left Negative (-)
to desaturated the color. Using this method also you can control the RGB by changing
it on a drop down menu on top of the Hue/Saturation bar window.
Channel Mixer
The best way i've discovered in converting your shot into black and white
is by using Channel Mixer where you can still control the RGB event after it has been
converted into monochrome. You can adjust the Red, Blue and Green in making the
image more punchy B&W shot. When adjusting the RGB, make sure the number as
close as it get to 100. so that you will not blown so much on the highlight and also
the shadow.

Do a little bit of experiment then you will understand it better, just make you save it
as a new image in different file so that you will not change the original image.
