I have to say, I do enjoy photographing vehicles. Not necessarily the fastest, sleekest sports cars either. I just like creating the best image I can for my client.

My client? Actually, on this occasion, my client is a marketing company, Moo Creations. They gave me an interesting, if very short brief. “We have a client who manufactures the refuse unit on bin lorries. Can you make it look sexy?”

Now, I'm more than happy to use a light painting technique, and have done numerous times previously. However, I'm also lazy. And if I can get a finished quality image in a quicker time, I will do so. (Between you and me, I prefer to use a quicker method if it means the shoot takes less time, as the client will benefit and that usually means more work.)

For the above image, I used two light sources. Frame left, I placed a 600Ws location light firing through a high intensity reflector. You can see the angle it hit the lorry by looking at the shadow of the front wheel, as it disappears under the vehicle. It was firing at full power.
Frame right was a second 600Ws location light firing at ½ power through another high intensity reflector. It was reduced to half power as I was able to place it nearer the vehicle without fouling the frame. The frame left light source on the other hand, needed to be much further from the vehicle to keep it out of frame, hence the need for full power.

The camera was set on a tripod and the base image was shot at ISO200 1/250th sec f16. A second image was shot at ISO100 1/250th sec f16, and a final image was shot at ISO400 1/250th sec f16
Basically, I bracketed the image using ISO settings.

I couldn't bracket using traditional shutter speed settings, as it would have effected the recorded ambient light. I couldn't bracket using the aperture settings because not only would it have effected the depth of field between each exposure, it would also have effected the recorded light from the lighting rig. Bracketing the images using the ISO effects the whole exposure, and allows the images to be combined in post. This gives greater detail in the shadows and the highlights, and when processed with a conservative eye, can produce appealing images for the client. (I prefer to manually blend my images, because.... well, I'm a masochist!).

Here are a few more images from other shoots for the same client using the same technique.

I'm always amazed at how you keep the highlight reflections off of the glass and other reflective surfaces.

Angle of incidence.
Just assume every part of an item is a mirror. Light travels in straight lines and if you can imagine you would be able to see your light on a section or panel, just move it to where you wouldn't be able to. Most times simply raising the light stand and having the head angle down towards the subject is sufficient to kill any flare.

Digital has made it much easier than the days of polaroids. A test shot will soon tell you if your assumptions regarding the positioning of lights is on the button.

Does that make sense?

I get the physics of it, just have had a harder time applying it. Do you find it harder to control reflections w/ using larger modifiers as oppose to smaller ones?

It's much easier with a smaller modifier. The high intensity reflectors are possibly 12 inch across at the business end. If I do get a reflection of the light source, it's much easier to remove a small source than say a 120cm Octa

And as always, thanks for taking the time to do these. It's always fun for me to see how people do their projects. I would have never thought to use the iso bracketing to achieve that kind of a look, but your explanation of why makes perfect sense.
