This tutorial demonstrates Layer Blending Modes and explains how Blending Modes operate.
Understanding Layers
Blending Modes, how they function here.
To be able to utilise Blending Modes, you need at least two Layers open in the Layers palette. Blending Modes work by altering an image’s pixels depending on the Blending Mode and the image beneath it. For example, if you were to apply red-coloured type over a photograph, the type will automatically be applied to its own Layer - as illustrated below.
Undo Note You can step backwards at any time by clicking the top menu’s Undo Tool.
Please Note: Elements 8’s Orange Horizontal Bar The following Orange Horizontal Bar is exclusive to Photoshop Elements 8. Please link here to read my comprehensive Understand Elements 8, 9 and 10’s Workspace tutorial.
Blending Exercise 1 To work along with this first exercise, you are welcome to download the Flower Image I am working with Here. Unzip the file and open it onto Elements’ workspace.
Tip To centralise your image - snap it to the top menu’s orange horizontal line by dragging it towards it.
Now, activate the Horizontal Type Tool.
And apply red text of your choice over the Yellow Flower Image, as illustrated below.

To alter the way the type’s pixels react to the pixels of the Layer beneath; click open the Blending Mode list, and change its default (Normal) Blending Mode to Difference. The red type’s pixels will immediately react (Blend) with the yellow and blue pixels of the flower image beneath it - and as a consequence, the red type pixels will change colour. 
Take a little time to familiarise yourself with different Blending Modes and discover how they can change the top image’s colours.
1/ Blending Exercise 2 Close the Flower/Text image. Then download the image I am working with Here. Unzip the file and open the Portrait onto Elements’ workspace.
2/ Now, Duplicate the Background Layer by left-clicking and holding: then dragging the Background Layer over the Create a new layer icon found at the foot of the Layers Palette - as illustrated below.
3/ Working on the Duplicated Layer: from the top menu, choose Filter then choose Blur then choose Gaussian Blur. Enter a Radius of around 23, then click OK.
4/ Still working on the Duplicated Layer: change its Blending Mode from Normal to Overlay.

Note Changing the Blending Mode to Vivid Light - and lowering the Layer’s Opacity to around 84%, produces the following result.

Again, experiment with different Blending Modes, (and Opacities), and see how they change your image’s pixels.
Quickly Change The Blending Modes Tip To quickly change the Blending Modes; first left-click to highlight a Blending Mode of your choice.
Then immediately tap any one of the following Keyboard Arrow Keys.
The following list explains each Blending Mode’s function.
Normal Edits or paints each pixel to make it the final colour. This is the default mode. (Normal mode is called Threshold when you’re working with a bit mapped or indexed-colour image).
Dissolve Edits or paints each pixel to make it the final colour. However, the final colour is a random replacement of the pixels with the base colour or the blend colour, depending on the opacity at any pixel location.
Behind Edits or paints only on the transparent part of a Layer. This mode works only in Layers with Lock Transparency deselected and is analogous to painting on the back of transparent areas on a sheet of acetate.
Clear Edits or paints each pixel and makes it transparent. This mode is available for the Shape tools (when fill region is selected), Paint Bucket tool, Brush tool, Pencil tool, Fill command, and Stroke command. You must be in a layer with Lock Transparency deselected to use this mode.
Darken Looks at the colour information in each channel and selects the base or blend colour, whichever is darker - as the result colour. Pixels lighter than the blend colour are replaced, and pixels darker than the blend colour do not change.
Multiply Looks at the colour information in each channel and multiplies the base colour by the blend colour. The final colour is always a darker colour. Multiplying any colour with black produces black. Multiplying any colour with white leaves the colour unchanged. When you’re painting with a colour other than black or white, successive strokes with a painting tool produce progressively darker colours. The effect is similar to drawing on the image with multiple marking pens.
Colour Burn Looks at the colour information in each channel and darkens the base colour to reflect the blend colour by increasing the contrast. Blending with white produces no change.
Linear Burn Looks at the colour information in each channel and darkens the base colour to reflect the blend colour by decreasing the brightness. Blending with white produces no change.
Lighten Looks at the colour information in each channel and selects the base or blend colour - whichever is lighter - as the final colour. Pixels darker than the blend colour are replaced, and pixels lighter than the blend colour do not change.
Screen Looks at each channel’s colour information and multiplies the inverse of the blend and base colours. The result colour is always a lighter colour. Screening with black leaves the colour unchanged. Screening with white produces white. The effect is similar to projecting multiple photographic slides on top of each other.
Colour Dodge Looks at the colour information in each channel and brightens the base colour to reflect the blend colour by decreasing the contrast. Blending with black produces no change.
Linear Dodge (Add) Looks at the colour information in each channel and brightens the base colour to reflect the blend colour by increasing the brightness. Blending with black produces no change.
Overlay Multiplies or screens the colours, depending on the base colour. Patterns or colours overlay the existing pixels while preserving the highlights and shadows of the base colour. The base colour is not replaced, but mixed with the blend colour to reflect the lightness or darkness of the original colour.
Soft Light Darkens or lightens the colours, depending on the blend colour. The effect is similar to shining a diffused spotlight on the image. If the blend colour (light source) is lighter than 50% grey, the image is lightened as if it were dodged. If the blend colour is darker than 50% grey, the image is darkened as if it were burned in. Painting with pure black or white produces a distinctly darker or lighter area, but does not result in pure black or white.
Hard Light Multiplies or screens the colours, depending on the blend colour. The effect is similar to shining a harsh spotlight on the image. If the blend colour (light source) is lighter than 50% grey, the image is lightened, as if it were screened. This is useful for adding highlights to an image. If the blend colour is darker than 50% grey, the image is darkened, as if it were multiplied. This is useful for adding shadows to an image. Painting with pure black or white results in pure black or white.
Vivid Light Burns or dodges the colours by increasing or decreasing the contrast, depending on the blend colour. If the blend colour (light source) is lighter than 50% grey, the image is lightened by decreasing the contrast. If the blend colour is darker than 50% grey, the image is darkened by increasing the contrast.
Linear Light Burns or dodges the colours by decreasing or increasing the brightness, depending on the blend colour. If the blend colour (light source) is lighter than 50% grey, the image is lightened by increasing the brightness. If the blend colour is darker than 50% grey, the image is darkened by decreasing the brightness.
Pin Light Replaces the colours, depending on the blend colour. If the blend colour (light source) is lighter than 50% grey, pixels darker than the blend colour are replaced, and pixels lighter than the blend colour do not change. If the blend colour is darker than 50% grey, pixels lighter than the blend colour are replaced, and pixels darker than the blend colour do not change. This is useful for adding special effects to an image.
Hard Mix Adds the red, green and blue channel values of the blend colour to the RGB values of the base colour. If the resulting sum for a channel is 255 or greater, it receives a value of 255; if less than 255, a value of 0. Therefore, all blended pixels have red, green, and blue channel values of either 0 or 255. This changes all pixels to primary colours: red, green, blue, cyan, yellow, magenta, white, or black.
Difference Looks at the colour information in each channel and subtracts either the blend colour from the base colour or the base colour from the blend colour, depending on which has the greater brightness value. Blending with white inverts the base colour values; blending with black produces no change.
Exclusion Creates an effect similar to but lower in contrast than the Difference mode. Blending with white inverts the base colour values. Blending with black produces no change.
Hue Creates a final colour with the luminance and saturation of the base colour and the hue of the blend colour.
Saturation Creates a result colour with the luminance and hue of the base colour and the saturation of the blend colour. Painting with this mode in an area with no (0) saturation (grey) causes no change.
Colour Creates a final colour with the luminance of the base colour and the hue and saturation of the blend colour. This preserves the grey levels in the image and is useful for colouring monochrome images and for tinting colour images.
Luminosity Creates a final colour with the hue and saturation of the base colour and the luminance of the blend colour. This mode creates the inverse effect of Colour mode.
Lighter Colour Compares the total of all channel values for the blend and base colour and displays the higher value colour. Lighter Colour does not produce a third colour, which can result from the Lighten blend, because it chooses the highest channel values from both the base and blend colour to create the final colour.
Darker Colour Compares the total of all channel values for the blend and base colour and displays the lower value colour. Darker Colour does not produce a third colour, which can result from the Darken blend, because it chooses the lowest channel values from both the base and the blend colour to create the result colour.
