How did they do this ?

[gregorio!]

I found this incredible shot on the porsche website, and i wondered how they photoshopped it? I understand how you isolate an object then desaturate the colour from the background, but this shot looks like it was a little more complicated.
It can't have been a rig shot as its too far away - could it?
The shadow the car casts, looks fake to me. Was it taken trackside then the car selected, selection inversed to select the background then a motion blur added? Or was it a studio shot of the car, cleverly placed onto a pre-blurred Nordschleife track photo, Then some clever attention to the reflections on the side of the car?????
Any thoughts?!

rigs are quite long! Chase car is also an option (probable here). The shots are taken at about 1 mph. Lots of shopping gone on though.

Here's Matt (Gravy from this place) doing the rig thing on mine:





and the bottom 2 shots here are the results (rig & chase) www.stevecarter.com/astonV8.htm

I'd say that was a rig shot with a longish rig.

For an idea of how long rigs can be, check this thread on another forum (you might a few familiar names from these pages).

The Porsche shot is photoshopped, the reflections in the car are not burred as they would be with a rig. It was taken in situ but without that much motion. Much like this...

...only more work put into the blurring

I think Mr Beachbuggy is correct.

The reflections of the kerbing are a giveaway and the shadow looks far too sharp.

Not a bad effort but must try harder

After reading dobbo's dieselstation link, i'm impressed and surprised to hear that people use 10 meter rigs to take car shots

GetCarter, I've seen Gravy's site before but i didn't realise the aston was yours. Nice to have such a handsome car immortalised in those photos.

The non blurred reflections make sense for it being a static shot which was then shopped in a grantgb manner. Great tutorial by the way!

Thanks for the input all

Are you sure about that? The shadow moves with the car, so wouldn't it come out as sharp as the car, just like panned or car to car shots (I've never done a rigged shot)?

[poah]

its likely they took a picture of the car stationary then a motion one and shopped them together. gives you a sharp car pic with blurred background

Can i rephrase that for you:

My thoughts exactly. Thats why I didn't bother signing up over there and thought I'd ask my last question on here!

I've been lurking on DS for a few months now. You get some pretty frank feedback with no punches pulled. I wouldn't post my pictures there for fear of needing to put myself on suicide watch afterwards!

[poah]

You can do most of that in Photoshop. You do not have to strap the camera to the car.

you can do ANYTHING in Photoshop, but most still strap cameras to cars

Might be a dumbass question, but how do you black'n'white the background, but keep the colour in the target?

[trackdemon]

Few different ways, but one of the easiest is to desaturate then use th history brush to 'paint' back the colour.

Without sounding like a complete dunce, how would you go about that??

I learned how to desaturate, but the rest was a mystery!!!!!

[trackdemon]

History brush is in the tools pallet: 5th tool down on the right.

[jagdpanther]

Like this?

[poah]

I use layers.

top layer B&W bottom layer colour then use the rubber to remove area's from the top layer I want to see as colour
