Insulator Photography Tips

To ensure I can tell which insulator you have, please try to follow these 3 tips:

  1. Insulator should be in-focus. If your photos are turning out blurry, try moving the camera slightly further away from the insulator, or see if your camera has a macro (closeup) mode. Some cameras also allow for manual focus.
  2. Take the photo straight-on. Bringing the camera down to eye level with the insulator (rather than up above, or bird's eye view) is helpful for me to read the embossing.
  3. Please photograph the entire insulator. It's more helpful to me if you show the entire insulator, rather than a small portion of it. If there's a special detail or other feature you feel is important, you can use the third photo upload field titled "Embossing/Feature Detail".
