Hi Zoe, Can you post an image instead of a PSD file?

What I would suggest with tires area, due to the shadow and the lighting that is already on car I would use the outline of the shadow of the car incorporated it into the tire area. When I blow it up I can see the entire outline (faintly) it's possible to get a better tracing of it but the simple route I would go with is grab the shadow and after you get your background decide what's slowly needs to be faded out.

In the original, a lot of the information seems to be lost in shadows. The problem with this is that there will be some assumptions that have to made about where a tire is.

Some like to follow and include the shadow line in their isolation instead of trying to guess at where the tire is supposed to be.

Since you did attempt to include the tires, the main issue I see is with the left rear tire.

I would go from here....


To here.....

Great minds iDad!

Kind of like this, but more time with selection and perhaps a feathering of the shadow area a slight pixel or a few

This is a good candidate for a vector mask instead of a layer mask IMO.

In cases where it is difficult to do a selection in the shadow areas, I'll often add a temporary "levels" adjustment layer, and pull the RH slider almost all the way to the left to bring out whatever detail is present in the shadows.

Often, this is all I need to do to make a decent selection in the shadow areas. For the most flexibility, I always save individual area selections separately.

Although this technique certainly works well with the manual selection tools (eg, pen, lasso, polygonal, etc.), I find it most useful and a tremendous time saver in that it allows me to use automated selection tools in cases where the automated tools would not work well on the original image. Examples of automated tools include quick select, color range, and even 3rd party selection plugins such as onOne's Perfect Mask, Topaz's ReMask, Vertus' Fluid Mask, Asiva Select, etc..

Of course, one eventually has to merge the selection made on the normal image with any selections made on the brightened image. For this, using the options under Select / LoadSelection, eg, "add to", "subtract from", "intersect with") can be very helpful.

Finally, I should add that often the problem is not in the shadows, but in the highlight areas, or in the midtones (eg, fog scenes). The same technique (ie, using a temporary levels adjustment layer) works just as well in these cases -- just move both black and white endpoints to develop contrast where you need it.

PS - I first saw this technique suggested on a video tutorial by onOne Software at least 4 or 5 years ago, and it has been incredibly useful in my masking work.

Here's a tip I can give you...

Duplicate the car layer and with the Exposure Adjustments, you can bring out the details in the shadows and save you from the guesswork in doing more accurate Pen Tool selection.....



Create the selection on the duplicate and when done, proceed as you would but on the original layer.

Hope this helps.....

LOL..... Didn't see tom's post.....

Many ways to do it Vee,(as you know) that's what's so confusing about Photoshop sometimes, but usually the ends justify the means. It is a nice concept Car.... I want one:mrgreen:

Same thoughts here, dad. But as long as you get what you're looking for, who cares if theres a 101 ways to do it?

Looks like a cross between a Fairlady, Mercedes' gull wing , and a Lamborghini front?

 

[iDad]

Not I, I am care free!... My well-maintained blood pressure can vouch for that:mrgreen:

edit: probably shouldn't of said that, now I'm probably go and have a stroke! just in case I do adios amigo!:mrgreen:
