Photography Question 

Deb Koskovich
 

Reflections will be the death of me...


 
 
I used a polarizer here and rotated it until it looked like all was well. This was the best of the several that I took of this particular shot. I know shooting cars in bright sunlight is asking for trouble, but if the car show is on a bright day, and the car you are interested in happens to be in the brightest spot -- what else could I have done to improve my chances?

  Just do the best you can. Sometimes that's not much. I had an owner tell me a while back that he didn't like it when there were no reflections..said it made the paint look dull..go figure.

  Polarizers don't remove every reflection.
When you rotate it you remove reflections from different areas as you rotate.
You pick the best overall result.

  I learned from NY Institute of Photography that polarizers only work on glass and not on metal objects.

  Carry a black reflector and put it on top to cover the reflections. In this case it would have worked because you only photographed a portion of the car.

  Along with what Debbie said, you can get a 5 in 1 reflector with diffuser. You can either use the black reflector to block the light, or the diffuser to filter the light (if you need more light). Something like this.

You can use a stand, or just bring a friend along to hold it.

  Thanks so much for the wonderful tips. I will be buying the 5 in 1 reflector right away.

  Be sure to shop around for the size and shape you want. There are many different varieties, and prices. The link I posted was simply one out of many, just as an example.

  Polarizers work on painted metal. And there's other surfaces besides glass.

  Hello Deb,

withoug going into a particle physics discussion, (heh-heh)...Polarizers do exactly what they are intended to do; polarize or (re-polarize) light.

There are many types and sources of light; many visible, most invisible.

A polarizing filter is totally (angle and refractive dependent.) So depending on the time of day, (vertical & horizontal sun position) and also clouds, dust etc, you will get varied results.

In your example, what you are seeing can not be completely defined as (polarized light.) You have some of what is known as (specular) reflections. No amount of polarized filtering will eliminate these.

  Hi Pete -- wow, my head is spinning LOL. But I do get what you mean. By specular reflection, do you mean for example the reflection of the headlight mount that shows up directly under the headlight? I see what you mean about that not being affected by a filter and actually that particular reflection doesn't bother me -- it's the dang trees on the fender! But obviously if I'm going to continue shooting at car shows I will either get better at eliminating them as much as possible, or go crazy trying. I'm definitely going to try the great suggestion of using a black reflector held by a friend (actually, an extremely patient and supportivie husband.) Thanks so much for your input, I really appreciate it.

  Yes,

The headlight mount has a specular reflection...Moreso within the headlight itself.

If you've ever seen a commercial setup for shooting automobiles, you will notice that they are almost ALWAYS shot inside with MANY light modifiers...not just strobes...You'll see many (30-40) scrims, gobos, panel diffusers etc. Even if you see a auto advertisement that appears to be shot outdoors; it probably was not.

In your example, using a diffuser will probably not work due to the shape of the fender..convex AND concave in shape, so what will probably occur is you will see the shape of the diffuser and/or black card being used as a blocker. It WOULD work IF you had a big enough diffuser.
Photographing an automobile so it is aesthetically pleasing presents a extreme challenge..building a good one, even more of a challenge..Just ask Ford..heh-heh..Just kidding; I think? LOL

  Well, I'm a born & bred metro Detroiter and I come from a long line of GM employees on my father's side, so I concur with your assessment of Fords. I've only ever owned one, and it self destructed at about 55,000 miles, LOL. I mentioned buying a Toyota when I was about 22 and I was threatened with disinheritance, thus I drive Chevies to this day...
