Underwater macro tips for Catalina Island


  • Nudibranchs are most prevalent in March - June, in 50-120ft of water.
  • The Two Harbors area, especially Ship Rock, will have the best nudibranch selection.
  • Also look on the bow of the Valient Wreck, deep at the West end cove, at Farnsworth banks and at Little Farnsworth
  • A 60mm lens with a 1.4x teleconverter, or a 105mm lens with a wet diopter are great setups.

Great photos Scott! Looks

Great photos Scott! Looks like conditions were good. I love the first blue-banded goby shot. I know shooting with the 105 is challenging!
