How to Use the IceCap 18000K and 20000K Magnetic Mobile Lens Filters

User Instructions:

Step 1: Attach the Lens to Your Phone

  • For MagSafe iPhones (iPhone 12 and newer): Snap the magnetic filter ring directly onto the back of your iPhone®, aligning it so the lens completely covers your main camera.
  • For non-MagSafe phones: Attach the included adhesive magnetic plate to the back of your phone or phone case first, then snap the magnet mount lens onto it.

Step 2: Choose the Correct Filter Ring

If you purchased a multi-lens kit, swap out the glass filter rings based on your aquarium lighting:

  • 20,000K (Yellow): Use this if your aquarium lights are a mix of white and blue (10K to 14K look).
  • 18,000K (Orange): Use this if your aquarium lights are set to a heavy blue/actinic spectrum (15K to 20K+ look).

Step 3: Adjust Your Camera Settings

For the best results, don't rely solely on your phone's automatic mode. Adjust these settings manually in your camera app:

  1. Turn off the flash: External lighting will cause reflections on the aquarium glass.
  2. Lock your White Balance: If your camera app allows manual white balance, adjust it until the background sand or rocks look white/grey, not blue or overwhelmingly orange.
  3. Lower the exposure: Tap on a bright coral and slide the exposure brightness down slightly to prevent "blowing out" the neon fluorescent colors.

Step 4: Line Up the Shot

  • Get close to the glass: Hold your phone camera flat against the aquarium glass to eliminate glare and room reflections.
  • Shoot straight on: Avoid shooting at sharp angles through the glass, which can cause distortion and blurriness.

Pro Tips for the Best Photos

  • Reduce deep/royal blue and cool white channels, and increase warm white
  • Hold the camera perpendicular to the glass
  • Turn off ambient room lights
  • Keep auto white balance ON
