Seacam Seaflash 250 strobe, underwater TTL test
Underwater photographer and Wetpixel friend Stephen Frink has posted an underwater TTL test from his most recent Digital Master class in Key Largo, Florida.
Basim Nasr showed up with a brand new Seacam housing for a Canon 1DMKIII and a pair of Seacam Seaflash 250 strobes… If TTL works, then the light on the exposure slate should be the same. As an aside, I have rarely seen a digtial TTL test that truly worked underwater. This one did.”
Check out the test. It’s pretty impressive—the slate retains the same exposure while the background gets darker and darker (as expected when working with a proper TTL system).
