David Bremner<p>My first attempt at black water photography was mostly unsuccessful (although the <a href="https://mathstodon.xyz/tags/dive" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>dive</span></a> itself was great fun). The main problem was getting TTL flash metering to fire the strobe without long delays after the shutter press. These days I mainly use manual strobe, so the screwups are mine, rather than the camera's ;).</p>
