F11 is the bare minimum. F13 and F16 are necessary sometimes and who cares about diffraction 😀 On these macro shots a tripod is mandatory. What NLE are you using? On Davinci Resolve, the Midtone details tool makes miracles. It's a micro-contrast tool that sharpens or softens areas with high edge definition. Ciao

I like the editing idea. The blenny watching what happens around it. At least that is how I understood it. Nice. I love videos that are not just simple slideshows of nice pictures. In general, macro images seem very soft to me, maybe too much. The focus almost always seems ok to me. On these little creatures we should always be careful to have the focus on the head, and preferably on the eyes when they have them. Maybe it depends on the aperture used? Here you really need F11 and beyond. And if you are at 50/60p you must be at least at 1/100 or 1/125 shutter speed. If you want to get a darker background, raise the shutter even more. The 180-degree rule is not so important underwater. Well done.

They are amazing. It's the so called Golden Kelp (https://en.wikipedia.org/wiki/Laminaria_ochroleuca) and it's present on both shores of the strait but it's deep. It starts form 65m/213ft. The colony on the Sicily shore is the best (the ones filmed in this doc). Roberto Rinaldi filmed the Laminaria with his Canon C500 MKII. P.S. A tragic note. The researcher speaking in the video is Lorenzo Bramanti. One of the top experts on mesophotic systems in the Mediterranean and a researcher at the French CNRS. Unfortunately, Lorenzo died suddenly at the age of 52 in his home in Banyuls-sur-Mer, France, at the end of June 2026. https://reporterre.net/Lorenzo-Bramanti-chercheur-et-defenseur-des-forets-animales-marines-est-mort

Out of curiosity: what's the meaning of shooting @240fps?

Do you have some clips showing the focus problem?

Close-ups at 0:41 and 1:41 are shot with the Inon G165.

IIRC this video of Vincenzo Striano was shot with the Inon G165. Try to reach him on YouTube, I'm sure Vincenzo will be glad to give some feedback.

I agree that in the hands of a professional it can get interesting effects, but in general having a wide lens and not being able to focus beyond 2.5 meters is a big problem. Inon and AOI will be forced to redesign their lenses, or this Mission 1 will be forgotten in a short time. The swan song of a company on the brink of despair. In the coming months we will see if these companies want to invest money in this project. The situation with close-up lenses is interesting. I have an AOI UCL-03 that I used for a project. Looking back, I should have bought the Inon, which is much more flexible. The AOI has a focus range of 4 to 8 cm, while the Inon has 10 to 25 cm. It is much more versatile. If the reduction of the focus range also applies to these lenses, my AOI becomes unusable. Inon, who knows. With the GoPro 11 I had to use a brush where I had marked the focus range with colored tape. I used it for time-lapses of gastropod mollusks.

Ciao Beppe, Welcome aboard! We hope you will enjoy the forum. Ciao

Kintsuglue or Sugru.

Unfortunately all those devices (using the 555 timer) work only if the powered device is on. So, in this case if you shut down the camera the keep alive device doesn't send the pulse. As tou wrote he could connect the keep alive on another port but it need a minimum resistance load as a small led or a resistor. Edit: Another test to be done is using the camera sleep functionality instead of powering it off. """Maybe"""" the small amount of current drawn is enough to keep the power bank awake.

Impossible to know. I have everything Nauticam and I use their lubricant. I only noticed that Nauticam one looks exactly the same i use on my O2 cleaned regs and rebreather.

In 15 years, I have never had to buy any grease for O-rings. Every housing and every Nauticam port comes with a tube inside, and you need so little of it that they are practically infinite. IIRC, in the past, at some trade show, I even scrounged a couple of tubes from the Nauticam importer by threatening him 😁 Having done technical diving for over 20 years, I can confirm that it must be a lube with a percentage of PTFE. Nauticam lube is practically identical to oxygen-compatible lube . Christolube is terrible because it leaves dry residue, unlike other apparently unbranded types that I use.

A dreamlike setting... Very nice video. Thanks for sharing

Hei @atus any news on your Med BW?
