Understanding Grayscale In Elements











As you know you can turn your images or photos into grayscale via Elements. The grayscale colour mode uses an 8 bit pixel which is made up of the following (8 on/off light switches) to generate 1 black and 1 white and 254 shades of gray. One of the ways to use grayscale images or photos is via scanning, the reason being it's easier to scan in black and white.

You find now a days mainly because of the speed and the power of Photoshop Elements most photo restorers are switching to RGB colour space, and the main reason being because of it's versatility, because it can generate millions of colours, or in this case millions of shades of gray.

Despite the very big move to RGB the grayscale colour mode is still used extensively on nearly all black and white photos or images, this is because of the files size. Grayscale images are 2/3rds smaller than RGB, so this is a great help to all the newspaper and magazines because they lack the ability to produce the detailed images or photos.

Using Grayscale In Elements:

1- Open you editor and then open you image.

2- Next you need to click on the image menu, and then select point mode, and then click on Grayscale. You'll now see that you image has been converted into Grayscale.

3- You might be prompted, if so click Flatten or Merge, to merge multiple layers into one.

4- Next click OK to discard colour information.

Also you can colour a grayscale image. To do this you need to be in Editor, next convert your image into the RGB mode, next you need to create a new layer, this needs to be above your image layer. Next you then need to select your brush size, this can be found in the Options Bar at the top. You need to change the blending mode of the brush for this to work. Next just colour your image and the new colour you have selected will replace the gray.
