Sataya is an outer reef that you can reach on a day snorkelling trip from Benerice south of Marsa Alam in Egypt home to 80+ doplhins in at least 3 pods
I went there with my family and whilst my daughter was finning around I was shooting video
I took few stills all breathholding to a depth between 0 and 10 meters those are the outcomes, as I was carrying an ND8 filter to avoid the shutter to go to fast at the surface the deeper shots are at ISO 1000 but still look good on the GH5
