Maybe dumb, but how do you open a car mockup in real size?
We photograph the vehicle, measure it and work in full scale.
Those store bought things have gotten really close to screwing me on a couple occasions.
Not to mention the 12 different versions of the Transit Connect, holy cow!!!
Cool trick. One point I should have made is to be aware when taking the image to be straight on to the vehicle, square or ruler, perspective can be an issue.
Nice Technique!
I use a green strip 500mm long and use dynamic dimensions to resize the car.
