Blending Modes - an explanation
I created a three layered image top layer is a Celtic Cross, the middle layer is the moon and finally a background layer (which is the original Celtic Cross photograph) Normal mode the pixels of the moon layer are unchanged and the moon appears as it was in it's original photograph 
In Dissolve mode the feathered edge of the moon has created a splattering effect but the main unfeathered part of the moon remains unaffected 
Darken mode selects the darker tones of both layers - lighter pixels replaced darker ones stay the same. 
Multiply mode is similar to when you overprint an image or colour over a picture with a felt-tip pen the image will darken the colour of the underlying layer however the light parts of the moon layer have caused no changes to the underlying pixels. 
Color Burn mode merges the darker colours of the upper layer, white has no effect. 
Linear Burn mode darkens the luminosity of the lower layer 
Lighten mode selects the lighter tones of either layer as the final colour - darker pixels are changed while lighter one remain the same. 
Screen mode has the opposite effect of Multiply it lightens all the darker tones. 
Color Dodge has the opposite effect of Color Burn, uses the blended layer to add colour and brighten the colour of the base layer. 
Linear Dodge Lightens the luminosity of the lower layer. 
Overlay mode is similar in effect to Multiply but holds onto the the base colour's highlight and shadows producing a more contrasty appearance. 
Soft Light mode a more subtle version of Overlay but if the blend colour is lighter than 50% gray it will lighten and if darker than 50% gray it will darken. 
Hard Light mode Adds colours together and like Soft Light darkens tones darker than 50% gray and lightens tones lighter than 50% gray but has a much harsher effect. 
Vivid Light mode increases the contrast even more creating bright white and deep black areas. 
Linear Light mode appears to dodge the tones to give a more brighter overall effect.
Pin Light mode changes the transparency of the tones of the blending layers according to how near 50% gray they are, painting with a brush at 50% gray will be 0% opacity - totally transparent. 
Hard Mix mode has a posterising effect. 
Difference mode alters a tone to the inverse tone giving a negative effect. 
Exclusionmode similar to Difference except of a lower contrast. 
Hue mode comines the colours including the luminance and saturation of the base colours and the hue of the blending colour. 
Saturation mode takes the hue and luminance of the base colour and mixes it with the saturation of the blending layers. 
Color mode retains the luminance of the base colour and mixes it with the hue and saturation of the blending colour. 
Luminosity mode has the opposite effect of Color mode mixing the hue and saturation of the base colour with the luminance of the blend colour.  |
