Guys... firstly, I'd like to tell that this is adapted from some place in the net i got sometime ago... This tutorial deals with a unique method of changing the color of a car... call it body painting Unlike traditional ways of changing a vehicle's body colour, this technique uses layer mask and various blending modes to preserve reflections making it extremely difficult for others to figure out if the image was digitally edited. 1. Open the image for editing, suppose: 2. Add a new "Hue/Saturation" adjustment layer (Layer> New Adjustment Layer> Hue/Saturation) and set the "Saturation" to "-100". Click OK. 3. Create a new layer as the top layer and fill it with the new colour of the car. 4. Set the current layer's blending mode to "Multiply" and add a layer mask (Layer> Add Layer Mask> Reveal All). 5. With the current layer's layer mask selected, use the eraser tool to erase the areas around the body of the car. 6. With the Hue/Saturation adjustment layer's layer mask selected, use the "Apply Image" tool (Image> Apply Image) to apply the following properties: Source: filename Layer: Layer 1 Channel: Layer Mask Blending: Multiply Opacity: 100% Click OK. 7. Duplicate the top layer (Ctrl+J), set its blending mode to "Screen" and invert the layer (Ctrl+I). 8. Make a layer of the current layer's layer mask (Ctrl+Click on the layer mask). Use the "Apply Image" tool (Image> Apply Image) to apply the following properties: Source: filename Layer: Background Channel: RGB Invert: Uncheckmarked Blending: Multiply Opacity: 100% Click OK. 9. With the current layer mask selected, use the "Levels" tool (Ctrl+L) and drag the black input slider right until the bleeding edges of the current layer is gone. Make sure that the "Preview" checkbox is checkmarked. Click OK. 10. Compare the this technique to traditional Hue/Saturation techniques. Rollover the image in this step to see the original image before this technique was applied.

Kindly bear with it.
