I dont' think there's any way you can bend the shadow so it fits a photo - only way is to model that sidewalk IMO. You can lighten the shadow with the Shadow blur radius and probably change the colour by adding some coloured spotlights - I've seen it done but I'm not really sure HOW to do it myself Great effect btw, it looks very believable in that photo. I don't think anyone would notice the "non bending at the sidewalk" thing unless you point it out.

The poser 5 shadow catcher would probably work with an object made to look like the road and sidewalk shape.

Yowza, this looks terrific. cheerio lululee

I fought with the shadow color. All I could get was only grey and dark grey. I needed to get a dark blue for a shadow.

Looks like parking enfocement in my part of town. Looks really nice. Shadow catching in P6 has not worked at all for me, too contrasty and not enough coverage... I have used an old fashioned shadow catcher I saw in someone tutorial for how to composit images, she put scaled white ambient black refection box props whereever masses were in the image.. in this case, road and curb, this shadow can then be color manipulated in a layer over the main or background image in an image editor. It is a cool and surprising image.

I discovered that changing "Properties", Parameters", "Others", "Shadow" of a particular light to a lesser value that 1.0000 will change the intensity of the shadow to a lighter shade of grey, but changing the actual colour of the shadow... now that's a duffy!

momodot's suggestion works best.

Render one image without shadows. Render a second image with shadows, and with "Shadow only" enabled in your render settings.

Layer the two images together in your paint program, using Multiply on the shadow layer. You'll have complete control over the hue/saturation/intensity of the shadow layer. They do that sort of thing all the time for movies like Jurassic Park.

What I did is have one IBL AO, and the other infinite. I noticed IBL AO have problems with shadows, unless someone can post otherwise about it. I used the infinite to give the suns position so I could get the proper shadow dimension. I did keep changing the shadow dial to get it darker, then lighter. I had it at about 3.500 which is shown in Pic above. It was very difficult to get a color to match the other shadows in the photo. For example the left side of road (Light pole shadow, and trees), then the building on left how the shadow has a blue to em.

Their are other dials when using infinite, I am not sure what they do. I haven't seen anyone chat about it. These are in "Depth Map Shadows": Shadow Blur Radius and Shadow Min Bias. Also I am not good in material room with lights.."Specular" and "Diffuse".

You can use a tool such as Eye Candy's "Perspective shadow" to bend a shadow to your whim in Photoshop...
