Behind the shot: Tambora Sandwich


Today, I’d like to tell you a nice story about mistakes, drone crashes, coincidences and one very cool shoot in which I took a panorama of Tambora Volcano in Indonesia.

Tambora is a volcano on the island of Sumbawa. In 1815, Tambora produced the largest volcanic eruption in recorded human history, which spewed 37-45 cubic kilometers (8.9-10.8 cubic miles) of rock, weighing about 10 billion tons, into the atmosphere. This left a caldera measuring 6-7 km across and 600-700 m (2,000-2,300 ft) deep. The eruption caused a volcanic winter, with 1816 being the second-coldest year in the northern hemisphere since around 1400. Now, doesn’t that sound like something you’d want to visit?

But first, let’s go back in time to a few days after the beginning of my trip to Indonesia in April last year. After taking a few days to do some formalities and get my work permit to allow me to guide my workshop a few weeks later, I used the rest of my time before meeting my participants to do a bit of shooting by myself. I took a short ferry from Bali to the small Penida Island (Nusa Penida), where I settled for a few days in the southwest of the island, where I could shoot some nice beaches with my drone. Unfortunately, this plan went south quickly when I crash-landed my (previously) trusty DJI Mavic II Pro into a tree, followed by it falling to the side of a cliff without any chance of recovering it.

It always hurts losing a drone. Not only are they expensive, but I was now lacking one of the most important tools I have as a nature photographer, and I still had over a month of shooting ahead of me. Luckily, I had invited Noah, one of my workshop participants, to arrive in Indonesia 10 days early to do some shooting together, and he was scheduled to arrive a few days after I lost the drone. I immediately asked Noah for help, and he gladly agreed to have a new drone shipped to him and bring it to me when he arrived. And so, I got a sparkling new Mavic III Classic. The accident and its consequences would greatly affect the upcoming Tambora shoot.

Noah and I traveled to our first shooting location: Moyo Island, specifically the spectacular Mata Jitu waterfall. A short motorcycle trip from our lodge, Mata Jitu is a wonderful gem located in a valley. It boggles the mind to think that in the distant past, people found this waterfall hidden deep in the middle of the jungle without any aids or roads. The waterfall features cascading pools of turquoise water created over the millennia due to the minerals contained in the flowing water.

Mata Jitu is fed by a beautiful stream, which is so serene that it’s almost always reflective. I took advantage and took an image of the stream and surrounding trees. For a longer exposure, I used an ND filter and a polarizer, which I positioned in a way that didn’t hurt the reflection. The high humidity condensed on my front element, enhancing the magical feeling in the image.

After wrapping up the Moyo Island shoot, we took a 2-hour police boat (that’s what we found, don’t judge!) to the main Island of Sumbawa. We spent the night in a local hostel and prepared for the main event: the climb to Tambora.

Tambora Volcano is one of the most famous Indonesian volcanoes and one that produced the largest volcanic eruption in recorded history back in 1810. Before the eruption, it was a conic volcano, standing 4500m above sea level. Today, it’s less than 2500m. Imagine an eruption so monstrous that it exploded through and destroyed 2km of solid rock. If you’re not scared, you’re not imagining hard enough.

Anyway, today the volcano is quite dormant, and you can easily climb up there, even scaling most of the way up with a 4×4, albeit in a crazy, hellish drive. The journey up the volcano begins next to the sea, in comfortable plains, but this quickly changes to denser and denser vegetation and alternating climate zones: fields, rainforest and finally, the barren wasteland you learn to expect when ascending a gigantic monster of a volcano. Our 4×4 was well-suited for the drive but kept overheating, which added some anxiety to the mix.

Our Tambora camp. Much better than nothing!

After finally arriving at camp, we turned in as early as we could since a very early rise was awaiting us. We were up at 2 a.m. to have a quick breakfast and start our climb. The night was rainy, and it wasn’t at all certain we would be able to get up there or even see the landscape, which was a bit discouraging. But the weather gods smiled upon us, and 2 hours’ trailless climb later, we were standing on top of Tambora with plenty of time to go before sunrise. The sky was luckily (and surprisingly) clear.

I hiked around a bit to get behind a large peak on the rim and prepared my drone for liftoff. When I sent it away, I could see a wonderful cloud inversion on the far side of the caldera. Having the Mavic III meant that I had the reception and battery capacity to fly almost 5km (over 3 miles) away and shoot the caldera with the cloud inversion surrounding the drone’s point of view from below. This definitely made the shot and made me feel very lucky to have lost my previous drone, even though I had to go through a lot of stress to get the new one. All is well that ends well.

Tambora’s volcanic crater is so gigantic that I had to get creative. I put on the wide-angle lens adapter and positioned the drone in the best vantage point I could find. This meant having the entire bottom of the image filled with the cloud inversion. I then proceeded to shoot a 3-row, 18-image panorama to cover the entire subject (with some margins for error).

Compositionally, it was important to include the clouds on both sides of the crater, as well as the bottom of the image. This is done to show the extent of the cloud inversion, which made even the huge caldera seem relatively small. In addition, note both the large cloud located slightly off-center to the left and the smaller clouds inside the crater. These subjects’ positions in the frame meant I had to have more compositional weight on the bottom right as a counterbalance. Luckily, the cloud inversion was thicker on the right, in addition to the prominence added by the light coming from the right side.

Noah and I, tired but satisfied on top of Tambora. Coffee was well-deserved.

Big thanks to Noah, who not only carried the new drone all the way from the US but also kindly allowed me to use his behind-the-scenes shots after my phone broke down during the trip.

Pentax K-1 and K-1 II firmware updates include astrophotography features (depending on where you live)

Yesterday, Ricoh quietly released firmware 2.50 for its Pentax K-1 and K-1 II DSLRs. However, the features you can expect to gain from this update may depend on your geography.

Ricoh’s English-language firmware pages for the K-1 and K-1 II state that firmware 2.50 delivers “Improved stability for general performance.”

However, astute Pentax users noted that Ricoh’s Japanese-language firmware pages (translation) indicate that the update also includes a limited feature called “Astronomical Photo Assist,” a collection of three new features designed for astrophotography: Star AF, remote control focus fine adjustment, and astronomical image processing.

Star AF is intended to automate focusing on stars when using autofocus lenses. Rather than manually focusing on a bright star and changing your composition, it promises to let you compose your shot and let the camera focus.

Remote control fine adjustment allows users to adjust focus without touching the lens and requires Pentax’s optional O-RC1 remote. Astronomical image processing will enable users to make in-camera adjustments to astrophotography images, including shading correction, fogging correction, background darkness, star brightness, celestial clarity, and fringe correction.

Astronomical image processing on the K-1 and K-1 II will enable users to make in-camera adjustments to astrophotography images, including shading correction, fogging correction, background darkness, star brightness, celestial clarity, and fringe correction.

According to Ricoh, Astronomical Photo Assist is a premium feature that must be purchased and costs ¥11,000 for an activation key (about $70 at current exchange rates).

Although these astrophotography features appear to be Japan-only for now, a Ricoh representative tells us, “Ricoh Imaging Americas confirmed that the premium firmware features for the PENTAX K-1 and PENTAX K-1 Mark II will eventually be available to US customers.”

Firmware update 2.50 for both the K-1 and K-1 II is available for download from Ricoh’s website.

On this day 2017: Nikon launches D850


When you use DPReview links to buy products, the site may earn a commission.

As part of our twenty fifth anniversary, we’re looking back at some of the most significant cameras launched and reviewed during that period. Today’s pick was launched seven years ago today* and yet we’re only quite recently stepping out of its shadow.

The Nikon D850 is likely to be remembered as the high watermark of DSLR technology. We may yet still see impressive developments from Ricoh in the future (we’d love to see a significantly upgraded Pentax K-1 III), but the D850 was perhaps the green flash as the sun set on the DSLR as the dominant technology in the market.

Why do we think it was such a big deal? Because it got just about everything right. Its 45MP sensor brought dual conversion gain to high pixel count sensors, meaning excellent dynamic range at base ISO and lower noise at high ISOs. Its autofocus system was one of the best we’ve ever seen on a DSLR: easy to use and highly dependable, with a good level of coverage. And then there was a body and user interface honed by years of iterative refinement, that made it easy to get the most out of the camera.

None of this is meant as a slight towards the other late-period DSLRs but the likes of Canon’s EOS 5DS and 5DSR didn’t present quite such a complete package of AF tracking, daylight DR and low-light quality as the Nikon did. With its ability to shoot at up to 9fps (if you used the optional battery grip), the D850 started to chip away at the idea that high megapixel cameras were specialized landscape and studio tools that would struggle with movement or less-than-perfect lighting. And that’s without even considering its 4K video capabilities.

In the seven years since the D850 was launched, mirrorless cameras have eclipsed most areas in which DSLRs once held the advantage. For example, the Z8 can shoot faster, autofocus more with more accuracy and precision, across a wider area of the frame and do so while shooting at much faster rates.

But, even though it outshines the D850 in most regards, the Z8 is still based around what we believe is a (significant) evolution of the same sensor, and its reputation still looms large enough for Nikon to explicitly market the Z8 as its “true successor.”

Nikon Z6III added to studio scene, making image quality clear

We’ve just received a production Nikon Z6III and took it into our studio immediately to get a sense for how the sensor really performs.

Dynamic range tests have already been conducted, but these only give a limited insight into the image quality as a whole. As expected, our Exposure Latitude test – which mimics the effect of reducing exposure to capture a bright sunrise or sunset, then making use of the deep shadows – shows a difference if you use the very deepest shadows, just as the numerical DR tests imply.

Likewise, our ISO Invariance test shows there’s more of a benefit to be had from applying more amplification by raising the ISO setting to overcome the read noise, than there was in the Z6 II. This means there’s a bigger improvement when you move up to the higher gain step of the dual conversion gain sensor but, as with the Z6 II, little more to be gained beyond that.

These are pushing at the extreme of the sensor’s performance though. For most everyday photography, you don’t use the deepest shadows of the Raw files, so differences in read noise between sensors don’t play much of a role. In most of the tones of an image, sensor size plays a huge role, along with any (pretty rare) differences in light capturing efficiency.

Image Comparison

As expected, the standard exposures look identical to those of the Z6 II. There are similar (or better) levels of detail at low ISO, in both JPEG and Raw. At higher ISO, the Z6III still looks essentially the same as the Z6II. Its fractionally higher level of read noise finally comes back to have an impact at very, very high ISO settings.

Overall, then, there is a read noise price to be paid for the camera’s faster sensor, in a way that slightly blunts the ultimate flexibility of the Raw files at low ISO and that results in fractionally more noise at ultra-high ISOs. But we suspect most people will more than happily pay this small price in return for a big boost in performance.
