Photographers are often told that they need a specialized camera bag to carry their gear. There's certainly no shortage of options these days, with a long list of brands and styles available. And while it's important to keep your expensive camera gear safe even when out and about, a dedicated camera bag isn't necessarily the only way to do that.

Can you put a camera in a backpack?

Simply put, a dedicated camera bag isn't necessary for many people and situations. They are often bulky and heavy. They typically don't work well if you need to bring a lot of things other than camera gear, making them challenging to travel with. They can also be conspicuous, raising the risk of theft. Plus, it can be hard to get the fit right, and spending a lot of money on a bag just to avoid using it because it's uncomfortable is far from ideal.

Most people already have a backpack or bag that they like carrying around, and may have occasionally even used it to carry cameras that have been carefully wrapped in a jacket or other articles of clothing. While we wouldn't recommend that too often, and would strongly advise against just tossing your camera loose inside a pack, the bag you already have could serve your camera bag needs with a simple accessory. Instead of buying a new bag that can only be used with your cameras, you could buy a much more affordable camera insert that goes inside your favorite pack.

Many companies, including Peak Design, Wandrd, Lowepro, and more, make padded inserts allowing you to safely store your camera in any bag. They are easy to move around to different bags as needed, giving you much more flexibility. Plus, you can take it out and use your backpack or bag without any camera gear. Just be sure you aren't packing the insert at the bottom of your bag with a lot of weight on top; they offer padding for protection, but aren't crushproof.

If you only have a small compact camera, an insert is likely more than you need. As long as you carefully consider where you are packing your camera in your bag, you should be okay without a specific case. Just ensure it won't have too much weight on it and that it won't get hit when setting the bag down or moving around.

When should you use a dedicated camera bag?

Inserts in everyday bags work well for many people, but a dedicated camera bag is a smart move for some. Wedding and event photographers who need multiple bodies and a full kit of lenses, for example, should invest in a camera bag. After all, inserts are generally smaller and not made to handle a lot of gear.

All that gear will also be heavy, and you want a pack that will allow you to distribute the weight well, saving your back over time. Camera backpacks are typically made with that weight in mind (the good ones, at least), making them more comfortable when loaded up. That is especially useful if you'll be wearing the bag for long periods, too.

If you're a professional photographer, you likely need plenty of accessories when you head to shoots as well. You need to find a home for things like extra batteries, filters, a cleaning kit, flash and, of course, snacks. Camera backpacks often have better organization options than standard packs, helping you keep all your gear organized and easy to find.

Many dedicated camera bags have another advantage over regular bags with inserts: quick access. An insert inside a bag requires you to take the bag off your back and open two things, potentially with some digging involved. Dedicated camera bags, though, typically make it easier to access your gear fast. Some even offer side access to get your camera out without even taking the pack off. So, if you need to keep your camera tucked away but still have easy access, a dedicated camera bag is the way to go.

Consider how you'll be using the bag

Whether or not you need a dedicated camera bag depends on your gear, where you'll be using it and your preferences. For travel and casual day trips, a camera insert in a normal backpack is likely a good move. However, a dedicated, well-designed camera bag will make a significant difference in comfort and organization for those carrying a lot of equipment, especially for long periods.

How Ryo Minemizu captures the hidden wonders of the ocean at night

Digital Photography Review news -

Underwater photography is a challenging genre to tackle. But the complexity is significantly amplified when you add subjects that are only a few millimeters large, and pitch-black nighttime conditions. Yet that's exactly what photographer and diver Ryo Minemizu is doing with his nighttime dives, also called blackwater dives. Minemizu took the time to answer some questions while on a sailboat in the Pacific Ocean, providing insight into how he captures incredibly unique creatures in the ocean.

When Minemizu started taking photographs while diving, he simply wanted to capture beautiful underwater landscapes and life forms easily visible to the naked eye. Eventually, though, he became more interested in what wasn't obvious, seeking out things that were often overlooked and fleeting moments that didn't get attention. "I was drawn not only to their beauty, but also to the strength and skill required for survival, and the deep significance of life itself," he said.

To find those fleeting moments, Minemizu has to dive in locations and times when most aren't venturing into the sea. Night dives opened up a new perspective, allowing him to capture creatures in, quite literally, new light. Minemizu also decided to focus on creatures that don't typically get attention. But that makes for tricky photographic scenarios. "Blackwater dive photography is arguably one of the most challenging and relatively new frontiers in the world of underwater macro photography," he said.

The dark conditions are perhaps the most obvious challenge. Minemizu says that for blackwater dives, a rope with multiple lights attached is suspended beneath a buoy, but its main purpose is safety-related, not for photography. In fact, "lights suspended from the buoy should be as dim as possible to avoid any negative impact on the natural environment," he explains. Instead, he said that divers mainly search for subjects in complete darkness, only using handheld underwater lights as they find them.

When it is time to light up a subject, Minemizu relies on five lights: two Marelux Apollo III 2.0 strobes for ultra-high-speed flash photography, two RGBlue (Super Natural Color) lights with high color rendering for use as target lights and for video recording in the dark ocean, and one INON LE-250 light used to illuminate subjects that exhibit phototaxis (when an organism moves in response to light). He uses the maximum flash sync speed to freeze movement, since the tiny creatures are constantly in motion. But it's not a set it and forget it situation. "Both the exposure and flash intensity are manually adjusted on site to suit the transparency of each subject," he explains.

While light is necessary in pitch-dark conditions, it can also have negative impacts. "Each subject has its own unique characteristics and behaviors," Minemizu explained. "For example, some would close their fins and begin to swim away the moment a light is pointed at them or quickly vanish into the darkness." As a result, he has to anticipate the subject's next move, rapidly assess how it will react to light and how it might behave, and make on-the-spot decisions about lighting. "This involves choosing the right color tone, the best angle for illumination and the appropriate light intensity," he said.

The size of his subjects is another significant challenge. Minemizu is primarily focused on photographing plankton, fish larvae and other minuscule creatures that only measure a few millimeters to a few centimeters. To show them at a large enough scale, Minemizu has to get very close to them. But the water between the lens and the subject adds more complexity. "Even small currents created during movement can disturb the subject’s posture, especially when operating near the minimum focusing distance," he explained.

The constant motion also makes it difficult to find and track subjects. "One of the most important tasks is to find the subject through the viewfinder and keep track of it without losing sight," Minemizu said. To help with that, he explains that a standard macro lens with a shorter focal length (around a 50 to 60mm equiv lens) is more effective than longer lenses. Focus is also a unique challenge. Keeping an animal's eye in focus while it moves around on dry land can be difficult, but imagine keeping that critical focus on a tiny subject floating around in the dark while underwater. After all, both Minemizu and the subject are moving in the current, so he only gets a brief window to engage.

Naturally, there's the gear component to consider as well. Minemizu uses Nauticam housing and the Canon EOS R5 with the EF-EOS R converter. For lenses, he sticks with the EF-S 35mm F2.8 Macro IS STM and EF-S 60mm F2.8 Macro USM lenses. He's opted for APS-C lenses because the equivalent focal lengths are ideal for his subject matter, especially the 35mm lens. He says he's eagerly awaiting an "RF-mount standard macro lens that fully takes advantage of a full-frame sensor’s capabilities," however.

Minemizu says that on land, his setup weighs 14 kilograms (about 31 pounds). To manage that heft underwater, he adjusts the balance and weight using float arms so the camera is perfectly level and neutrally buoyant, meaning it isn't sinking or floating. Those float arms are attached to the top and bottom, making it easier to rotate the camera vertically.

Beyond all the technical challenges, blackwater dives introduce physical risk. For safety reasons, Minemizu says he limits his dives to 25 meters (82') at night, though most are between 10 and 20 meters (32.8 to 65.6'). Occasionally, the subject he's photographing will begin to descend to deeper water, and he'll need to decide whether to follow or not. "Following it too far can become dangerous," he said. "In such cases, I need to maintain discipline and accept that there are moments I must let go."

While Minemizu's images are beautiful, they also contribute to science. Some of the subjects he's photographed are entirely new scientific observations. "In order to recognize such cases on the spot, it is essential for me to have a broad knowledge of plankton, acquired through my own study," said Minemizu. He is working in collaboration with scientists from the Smithsonian Institution and conducting joint studies with universities and specialists studying jellyfish, cephalopod larvae, crustacean larvae and the larvae of various other invertebrates.

Panasonic S1II video stills: so many options

With the S1II, Panasonic continues the tradition of offering "open gate" recording that uses the entire sensor area, which, like with the S5II, produces a roughly 6K 3:2 image (though the S1II's rolling shutter is substantially faster). This mode provides great levels of detail and more flexibility in post; if you're working on a 4K timeline, you have a fair amount of room to reframe a shot, and you can use the same footage for both landscape and vertical output.

The camera also has a 5.1K open gate mode with a little less resolution and detail. That cuts down on its flexibility, but allows for a first for full-frame Lumix cameras: open gate recording at 60p. The 5.1K 24p and 60p modes apparently have the same level of detail.

The camera's 4K modes are all oversampled from 6K capture, and have similar levels of detail to those of competitors like the Z6III and EOS R6 II, even at up to 60p. The S1II can't quite manage full-width 4K 120p, but the mode only requires a 1.24x crop, rather than a 1.5x crop like with the Z6III. So while there's some reduction in detail compared to the slower framerates, it does capture a tad more detail than the Nikon, and will come with a smaller change to your field of view.

If you don't prefer oversampling, the S1II also offers a 16:9 5.9K capture mode and a 1.89:1 5.8K capture mode, both of which are available at up to 60p. The extra resolution offers a bit more detail and more flexibility in post, though not quite as much as the 6K open-gate mode.

Raw video

Like the S1RII, the S1II can record ProRes Raw internally, capturing a native 5.8K region of the sensor at up to 30p, or a native DCI 4K region at up to 60p. This mode may be useful for those on professional shoots that need the utmost control over their footage, but for reasons we explained in the S1RII writeup, Raw video isn't something that most shooters will likely find useful. In short, it doesn't offer the same benefits that stills shooters expect from Raw images versus JPEG ones, and it will require a lot of post-processing work, especially if you're using modern mirrorless lenses that have geometric distortion correction as part of their optical formula, as Panasonic's implementation of ProRes Raw doesn't embed them.

The S1II is absolutely bursting with video modes, so this overview is far from comprehensive. Our chart detailing them in our initial review covers 166 different options, and it isn't even a complete list of all the configurations you can have. However, our testing shows that it's very capable of producing high-quality footage, even at fast framerates. Combine that with all the video assistance features that Panasonic includes, and it's one of the most flexible hybrid shooters we've seen.
