A nature photography tour of Madagascar part 5: Isalo and Ranomafana


Previously in this series, I talked about my visits to Andasibe NP, where I shot lemurs and chameleons, and to Tsingy Rouge NP, where I shot beautiful formations made by erosion. I also talked about shooting sifaka lemurs and baobab trees in Kirindy Forest reserve and about visiting several secluded stops on my way to the southern part of Madagascar. This time, I’ll talk about two short but fruitful visits: one to Isalo National Park and the other to Ranomafana National Park.

Isalo is a National Park in the Ihorombe region of Madagascar. It is a sandstone landscape dissected by wind and water erosion into rocky outcrops, plateaus, extensive plains and up to 200 m (660 ft) deep canyons. The park was created in 1962 and has been administered by the Madagascar National Parks authority since 1997. It includes landscapes considered part of the subhumid forests ecoregion. This ecoregion is home to numerous endemic species and has been given Critical/Endangered status because only small areas of native habitat remain, and most of those are highly fragmented.

As you’ve seen in previous articles, this fragmentation of ecosystems and, thus, the endangerment and rapid decline of endemic species is, unfortunately, very typical of Madagascar. Ecotourism is thus a most powerful and important tool to preserve what’s left of the fragile habitats and beautiful species of this poor country.

Isalo might not have infinite landscape photography attractions, but it does have some nice locations with fantastic rock formations, the principal of which is the famous rock arch. As with many locations in Madagascar, this arch is very crowded at sunset with tourist groups and locals but surprisingly empty during sunrise.

The arch can be photographed from both sides. The easier eastern side is basically connected to the road and is thus harder to shoot when it’s crowded, but getting to the shooting spot on the western side requires some agility and a bit of climbing and is thus much emptier, even during sunset. Thus, I chose to shoot the arch from the west during sunset and from the east during sunrise.

The western side a few minutes after sunset, under a strong post-sunset glow. This phenomenon happens when the western horizon is clear of clouds. The glow is surprisingly red and reflects beautifully off of brighter surfaces such as the rock arch.

Apart from the arch, there are eroded rock formations nearby, surrounded by fields where termites build huge mounds, which can serve as nice foregrounds.

As for wildlife, Isalo has a small variety, including the sportive lemur and the red-fronted brown lemur, which I had already seen and photographed. It also has a decent-sized population of the ring-tailed lemur, perhaps the most famous of this primate family.

Getting to the ring-tailed lemurs was a bit of a challenge, and it took some precarious rock climbing to get to the point where they were hanging out. Still, nothing extreme. Upon getting to the lemur group, I got plenty of interesting poses by the lemurs, which were super cute and fun to shoot.

“Why hello there!” It seems like this lemur was a top model in a previous life!

I intentionally left some negative space on top of the frame since that’s where the lemur is looking.

I will talk about ring-tailed lemurs much more extensively in the next article, but for now, I will say that it’s not only their beauty but their wonderful behaviors that make them a joy to shoot. One such behavior is licking the branches for a taste of pheromones. Both male and female ring-tailed lemurs have scent glands that secrete pungent substances, which some lemurs find irresistible!

Like other lemurs, this species relies strongly on their sense of smell and territorial marking with scent glands, providing communication signals throughout a group’s home range. The males will participate in stink fights by dousing their tails with their pheromones and ‘wafting’ them at opponents. Additionally, lemurs of both sexes will scent-mark trees, rocks or other objects by simply rubbing their faces and bodies onto it. I guess the eyes say it all.

What I’ll talk about next wasn’t the next stop in my trip after Isalo. That stop deserves its own article, so for now, I’ll skip it and talk about the very last stop – Ranomafana NP. The park protects more than 41,600 hectares (161 square miles) of tropical rainforest at elevations ranging from 800 to 1,200 m (2,645 to 3,937 ft) and is home to several rare species of plants and animals. Out of these species, I had a really good time shooting the golden bamboo lemur, a medium-sized lemur endemic to the area.

Golden bamboo lemur. These guys are super fast and jump around constantly, but once in a while, they’ll stop and allow a shot or two. I think they’re absolutely beautiful!

This was the second bamboo lemur I shot (the first was the gray bamboo lemur in Andasibe (see the first article in the series), but it was the most photogenic, and by far the harder one to shoot. I had to run across narrow trails through thick vegetation, sometimes only to find out the lemur had already gone away. But I was very happy with this final shot: a golden bamboo lemur inside a heart-shaped leafy frame.

It’s hard to beat cuteness in a heart-shaped frame. This was a difficult shot technically, as it was very dark inside the thick vegetation, and my camera found it hard to focus. Only a few shots turned out good, and this is my favorite. You may remember framing as one of the methods I discussed in my landscape composition series—I would say it’s even more useful in wildlife photography!

How one photographer turned a DIY dream into a full-frame reality

How one photographer turned a DIY dream into a full-frame reality


The Sitina S1

Here at DPReview, we love DIY photography projects, and one recently came to our attention that we just had to share.

Boston-based engineer and photographer Wenting Zhang has been experimenting with DIY electronics for over a decade and also loves taking photos, so building his own camera was a natural extension of these interests.

“I initially had the idea of building my own camera during middle school. Back then, I wasn’t allowed to use my parents’ camera and couldn’t afford a real camera. I naively thought it would be possible, and cheaper, if I just built one myself,” Zhang told DPReview. His initial attempt didn’t go well, and he eventually saved enough to buy a used Nikon D90, but the itch to build his own camera stayed. Whenever he saw someone posting about a DIY camera project, he thought, “If other people can pull that off, I should be able to as well.”

In this recently published video, Wenting Zhang walks through assembly of his current prototype camera.

Zhang says he started the project in 2017, and it’s not finished yet. “Engineers are usually bad at estimating how long things will take. I am probably particularly bad at that. I expected this project to be challenging, so it would take a bit longer, like probably one year. Turned out my estimation was off,” he says.

He makes clear to point out that this is a hobby project, purely for fun, and that his camera isn’t going to achieve the level of image quality found in commercially available products from established companies. Despite that, his project provides a fascinating look into what’s involved in building a camera from the ground up. What’s more, Zhang has open-sourced his entire project on GitLab for anyone else who might want to build upon it.

Zhang took this photo with a monochrome version of the Sitina, which uses the same sensor but without the Bayer color filter array.

Although CMOS has become the dominant sensor technology in consumer cameras, owing to factors like speed, lower power consumption and cost, Zhang’s camera is built around a 10MP Kodak KAI-11000CM CCD sensor with a global electronic shutter, which he selected for a rather pragmatic reason: it was easy to source. “Most manufacturers (like Sony) aren’t going to just sell a sensor to a random hobbyist, so I have to buy whatever is available on eBay. This 10MP CCD turned out to be available,” he explains.

The choice of sensor has a useful benefit. As he explains in one of his videos, designing and building a mechanical shutter is complicated and beyond his area of expertise, so his DIY design is based on using an electronic shutter. For similar reasons, he chose to use an LCD screen as a viewfinder rather than a prism-based optical design, resulting in a mirrorless camera.

Zhang wanted his design to be compatible with existing lenses. His mirrorless design, with a short flange distance, provided a great deal of flexibility to adapt different lenses to the camera, and he’s currently using E-mount with active electrical contacts.

And that’s just the start. Zhang also needed to integrate a CCD signal processor with an ADC (analog to digital converter), a CPU, battery, an LCD screen and buttons. He also designed and built his own circuit board with a power-only USB port, flash sync terminal, power button and SD card slot, and create the software and user interface to tie it all together.

In order to build his camera, Zhang had to design and print his own circuit boards.

Finally, everything fits inside a 3D-printed enclosure that, to my eye, looks rather attractive.

As for the camera’s name, the Sitina S1? “I simply put the word ‘silicon’ and ‘retina’ together to form the word ‘sitina’. I don’t have any better ideas of naming the camera model, so I simply call it the ‘Sitina S1’, he explains. “But the name may change in the future if I ever have better ideas.”

Zhang was kind enough to share some photos from his DIY ‘for fun’ camera.

Now that he’s built his own camera, Zhang has an appreciation for how much work goes into the design, development and optimization of a modern consumer camera. “I would imagine it would take an army of designers and engineers of various disciplines to build a modern consumer camera,” he says. “There are so many different components but few ‘off the shelf’ parts.”

“On top of the hardware, we still have layers of software. There’s no standard camera operating system (like Android or Windows) so each vendor is developing its own OS. On top of the OS, you have image processing algorithms where each vendor probably has their own secret sauce for better color, lower noise, etc. I think it’s quite incredible that camera vendors are able to do all these things in-house.”

In this video, Wenting Zhang dives into the technical details of what’s required to design a working camera.

Zhang is still working to address issues in his current prototype. “I think in another year or two it could reach a state where it can be a useable and useful camera. I do wish to sell the camera either as a kit people can put together or as an assembled machine. Not for profit, but so people can play with it, and my effort on this project won’t go to waste.”

If you’re curious to learn more about how a camera is built, I encourage you to watch both of Zhang’s videos in their entirety as he goes into great detail about the process. And, if you have the technical skills and interest to try this type of DIY project yourself, his open source project could be invaluable. I’ll be the first to admit it goes beyond my level of engineering know-how, but I would be first in line to order a Sitina camera DIY kit if the opportunity arose.

Fujifilm says X-H2/S and GFX 100S II will get AF improvements and new F-Log2 C mode



Today, Fujifilm announced an upcoming firmware update for the X-H2, X-H2S, and GFX 100S II that’s meant to improve the cameras’ video capabilities.

In a YouTube video, the company says the update will improve the stability of autofocus subject tracking while shooting video. It’s also adding support for Ambient’s wired Lockit timecode synchronization devices and introducing a new F-Log2 C mode, which the company says will provide a much wider color gamut than the traditional F-Log2 that the cameras already had.

F-Log2 C uses a wider color gamut than the standard F-Log2.

The company says it’s currently “considering further enhancements” and that people should stay tuned. There’s clearly an appetite for more updates among Fujifilm users: currently, the video’s comment section is essentially wall-to-wall people asking why the update isn’t also coming to the X-T5 and the X-S20, and saying that they’re still hoping for additional improvements to autofocus performance in those cameras’ stills modes as well.

The updates for the X-H2, X-H2S, and GFX 100S II are expected to come out in November. We’ll be sure to let you know when they’re officially released and ready to be installed on your camera.
