LOFIC: the 17 stops claimed by the Osmo Pocket 4P and the future of sensors
LOFIC: the 17 stops claimed by the Osmo Pocket 4P and the future of sensors

Davide DB · August 22Aug 22

There has been discussion recently about the new DJI Osmo Pocket 4P. DJI claims up to 17 stops of dynamic range on its new 1-inch sensor, and comparisons with cinema cameras like the ARRI Alexa quickly surfaced online. Looking at the numbers, it might seem plausible, but visually the situation is different. Waveform plot for the DJI OSMO Pocket 4P 20mm wide D-Log2 ISO1600. Image credit: CineD Spoiler: no, it is not a micro Alexa. PetaPixel confirmed after testing it that LOFIC improves both

Shooting a Snoot
Shooting a Snoot

TimG · October 30, 20232 yr

Shooting a Snoot Underwater photography is an absorbing form of photography. For some, it’s a technical issue of capturing fish portraits. For others an art form about capturing the beauty and mystery of the underwater world. Whichever you aim for, it presents unique challenges. Everything moves: you, the water, and the subject. Photography is all about capturing and controlling light. In the underwater world lighting and highlighting the subject is often impacted by either a

UWT Trigger for Nauticam/OM System OM-1
UWT Trigger for Nauticam/OM System OM-1

TimG · August 8Aug 8

Having recently written about installing the o-Turtle trigger into a Nauticam housing, I’ve now had a go with a UWT internal trigger for the Nauticam NA-OM1 housing. UWT describes it as the 11072-22-HSS TTL-Converter for NAUTICAM for OLYMPUS/ OM SYSTEM. The UWT trigger arrives in a bubble-wrap envelope in a small cardboard box. No frills functional. It consists of a small electronics board with two LEDs and a cable leading to a hot shoe connector. The manual explains that strobes are selected

Strobe Triggers for OM System/Nauticam: o-Turtle and a Fitting Tip
Strobe Triggers for OM System/Nauticam: o-Turtle and a Fitting Tip

TimG · August 4Aug 4

Having bought a Nauticam housing and OM System OM-1ii recently as the base of my new underwater camera setup, I needed an LED trigger to fire the strobes. Although I havn’t used TTL underwater for many years, I did want HSS as I often include the sunball when shooting wide-angle. This usually requires high shutter speed to avoid exposure burn outs. HSS options for an OM trigger seemed to boil down to the Turtle or UWT. The Nauticam flash trigger, although an attractive option, doesn’t provide

Nikon defends the patent it tried to destroy and loses anyway
Nikon defends the patent it tried to destroy and loses anyway

Davide DB · August 7Aug 7

Panasonic achieved a result that Apple, Sony and Nikon did not. The Japanese Intellectual Property High Court invalidated a major RED patent concerning raw video files. RED had historically used this patent to demand licensing fees and stop competitors. Nikon initially challenged the patent in court but purchased RED before a ruling and dropped the case. When Panasonic recently challenged the same patent in Japan, Nikon defended the claims it had previously opposed. The court ultimately rejecte

Liveaboards: A Word to the Wise
TimG · May 17May 17

You may have read or seen pictures of the fire that broke out in the Maldives on the Emperor Explorer liveaboard on 9 May. My partner and I were on it as part of a group of 25. Like many members, we’ve been lucky enough to have been on lots of liveaboards. During the pre-departure safety briefing we were given the usual advice: If an alarm sounds do not return to our cabins to collect stuff: head immediately to the muster station by the dive platform; put together a grab bag in case of emerge
