5. (Optional) Use Photoshop to convert the image to grayscale. The simple way is to go to the
Image menu and select Mode > Grayscale.
Alternatively, you can go to the Image menu and select Adjustments > Channel Mixer, to choose
the percentage contribution of each color channel to the grayscale image, as follows:
a. Check Monochrome.
b. Drag any source channel's slider to the left to decrease the channel's contribution to the output
channel or to the right to increase it, or enter a value between -200% and +200% in the text
box (for example: 30% Red, 59% Green, 11% Blue). Using a negative value inverts the source
channel before adding it to the output channel.
c. Drag the slider or enter a value for the Constant option. This option adds a black or white
channel of varying opacity: negative values act as a black channel, positive values act as a
white channel.
d. Click OK.
