If your camera supports Bluetooth, which is likely the case for most modern cameras, setting up both Bluetooth and Wi-Fi connections is advisable. The camera tends to connect more seamlessly through Bluetooth, and if greater bandwidth is required, it will automatically switch to Wi-Fi. This approach offers improved reliability and faster performance.

Initially, I was skeptical about the usefulness of wireless connections between smartphones and cameras. However, my perspective has shifted, particularly after extensively using them for remote live view photography. This functionality proved indispensable in such scenarios. There was, however, one challenge, establishing a stable Wi-Fi connection.

The main objective of the receiver is to collect as much as possible of the incoming signal and to couple it either to a photodetector or an optical fiber. Therefore, the design of the receiver tends to be more crucial than the design of the transmitter. An important aspect is its alignment tolerance, i.e. how much the receiver is allowed to deviate from the optical axis.

Feel free to share your experiences and uses of wireless connections between cameras and smartphones or other devices in the comments below. I'm eager to learn about your insights.

While not all the available wireless connection options are equally beneficial, having these choices at your disposal is valuable. Even if you personally don't find them useful, others might find them indispensable. Ultimately, the presence of these options provides flexibility without imposing an obligation to use them.

Personally, I can’t see the benefit of transferring captured images directly to a smartphone. Storing raw or JPEG files on a limited smartphone memory doesn't make much sense. If you have valid reasons for doing so, I'd be interested to hear about them.

In my opinion, this functionality is genuinely useful. You need to keep the effective range between the smartphone and camera in mind, because there is a limit. If that becomes an issue, a wireless radio trigger serves as a more practical alternative. On top of that, it's easier to use, potentially quicker, and requires less attention to find the trigger button. Nevertheless, there are situations where the built-in wireless connection's convenience shines.

Transferring photos to your smartphone is another possibility. Both raw or JPEG files depending on the app, and some cameras even support FTP connections, enabling you to save images on a server, computer, or smart device. However, beyond studio environments, I struggle to see the benefits of wireless file transfer options. Even for studio photography, there might be more efficient alternatives for transferring images, like tethered shooting.

For those who've never used their camera's wireless connectivity before, the question of its benefits might arise. I myself had these doubts initially, but I've come to realize that it can indeed be quite useful, sometimes even essential. However, there are instances where alternative methods might be more convenient.

I like Cascable app. I tried with cable to my iPhone. That’s my choice, and Capture One in studio, with cable. Both offer support wireless.

Thankfully, improvements in smartphone apps and camera software have made the process more streamlined than ever before. Even so, setting up a wireless connection can be challenging nevertheless.

I’ve heard similar complaints by photographers using Sony and Nikon cameras. While I'm more acquainted with connecting my smartphone to a Canon camera, I've encountered some peculiar issues with it as well.

The main purpose of the transmitter optics is to produce a suitable beam divergence matching a desired beam diameter at the receiver. Without transmitter optics, the beam divergence would produce a beam too large to be of practical use (around 200m a distance of 500 m). Moreover, a desired feature of the transmitter optics is that it should add a minimum of aberrations (specially spherical aberration).

One step up from a simple remote trigger is remote live view. There are instances when I need to control the camera remotely, such as when it's mounted on a pole at a height of two to eight meters. This is when I find the remote live view function of the Canon app invaluable. It allows me to preview the shot and adjust exposure settings as needed.

I only use the wireless connection as a remote trigger, combined with live view when trying to shoot insects on flowers and not scaring them away with my presence ( the insects not the flowers ) And just purely as a remote when I place my tripod in the water and don’t want to make ripples in the water with my movement.

Combining Bluetooth and Wi-Fi turned out to be a great solution, provided your camera supports both. Unfortunately, good documentation on wireless connection setup is often lacking, and discovering the most efficient and user-friendly way to connect your smartphone and camera requires some research.

To calculate the actual contact angle, surface roughness and contact angle are to be measured simultaneously to get the roughness corrected contact angle.

I used the app on my iPad when travelling to go through the images and select the images to be deleted. In the meantime my eyesight changed so I now use the backside screen of my cameras without glasses, because it's much simpler. As the Leica Q2 doesn't have an articulating screen for selfies I once used the app, but it's ... rather stupid, so I went back to using my smartphone.

On the downside, FSO communication is affected by the mentioned atmospheric effects, which limits sensitivity and achievable data rates

My experience with the Fujifilm X100T has been somewhat challenging. Establishing a connection between my smartphone and the camera via Wi-Fi often required a considerable amount of effort. Even when successful, there was no guarantee that the connection would work smoothly a second time around.

Almost every modern camera comes equipped with some form of wireless connectivity. Manufacturers are even making them a prominent selling point. But just how valuable is this feature in reality? In this article, I want to dive into the possibilities and their value.

Do you know if it’s transferring the RAW files or just tiny preview jpegs? I think for a long time it only did the later but maybe it’s better now.

I've gotten used to making connections to Sony cameras. Not as streamlined as these connections should be, but not bad after you have done it a few times. Olympus isn't too bad. My one Panasonic camera is a pain. I go through the steps and the app says it is connecting, but takes a long time, assuming it ever connects.

Enabling the shutter remotely via a wireless connection is a great option. This is particularly true when you want to include yourself in the frame. With this feature, you're no longer bound by the 10-second self-timer for positioning yourself. Additionally, the 2-second or 5-second self-timer options provide enough time to conceal the smartphone out of sight.

Being able to shoot and have the images jump straight to a phone (wireless tethering, so to speak) beats shooting with the phone itself if you prefer the image quality a camera offers, and lets you share to social or elsewhere without the step of later connecting to the camera, browsing the tiny thumbnails in a sluggish interface, and then downloading only those you think you want (but might be out of focus, hard to tell from the tiny thumbs). Lightroom for mobile is full featured and a lot of people prefer the editing interface on their phone anyway. Yes, storage is obviously the big limitation, but if you’re okay with that the camera and apps should facilitate it.

The wireless capabilities of contemporary cameras are becoming increasingly sophisticated with each new model release. Personally, I've observed significant improvements in the way these connections operate, at least in the context of my Canon cameras. However, I must admit that I haven't extensively tested this feature with all the other camera brands I've reviewed so far.

FSO are communication systems in which the signal is propagating through the air or vacuum. One of the reasons why FSO are so attractive is because they offer great flexibility and relatively low cost to be deployed while providing high transmission data. For example, FSO networks can be configured for point-to-point, point-to-multipoint, multipoint-to-point, or multipoint-to-multipoint.

Stability of the connection is another factor to keep in mind. I've noticed that something as simple as a sleep mode or standby setting can disrupt the connection, especially with Wi-Fi. Also, if your smartphone detects a known Wi-Fi signal that has more signal strength, it might switch over without warning. If this happens, it might prove a lot of effort to restore the connection.

If you're interested in adding GPS coordinates to your photos, the wireless connection between your camera and smartphone enables the camera to gather GPS data, which is then automatically embedded in the image's metadata. Keep in mind that for this feature to work, your smartphone needs to remain continuously connected. Bluetooth is likely the best option, although a Wi-Fi connection could also suffice. While this could impact your battery life, the effect might be less significant compared to using a built-in GPS system.

In my experience with the Canon EOS 5D Mark IV, establishing a reliable Wi-Fi connection proved challenging at times. Particularly when a known Wi-Fi network was available, my smartphone seemed to prioritize that network over the camera's. However, when it did work, it worked flawlessly when I used the camera mounted on a pole.

Transferring images to your smartphone might prove useful if you intend to share them on social media or perform post-processing on your smartphone. Yet, this method strikes me as labor-intensive. The process involves taking a photo with your camera, switching to your smartphone, opening the image in an app, applying post-processing, and finally sharing the photo. Why not simply take the picture using your smartphone in the first place? It's a more straightforward, time-saving, and often a user-friendly approach.

You mentioned a good point. My cameras only take a single memory card. I knew that using the Sony app as remote would upload an image to the phone automatically. A little slow since the app pauses for the upload. Then I tried something different. I used the camera in the normal manner while connected to the app in remote control mode, and I found it still sent a copy of the file to the phone. Now my phone acts as backup storage.

This functionality proves beneficial for various photography styles, including macro photography or situations where the camera is positioned out of easy reach. For me personally, this is the most useful wireless connection feature.

So far, all I get is a 1616 x 1080 jpeg when it automatically sends to phone. Sending to phone afterwards I get a 6000 x 4000 jpeg, but my phone might not be able to handle a RAW file transferred that way. The app does say it will send RAW or HEIF if the phone is capable.

A previous post discussed underwater optical design. This week, we will review the diametrical opposite application – free-space optical communication (FSO). As with underwater optical design, one of the challenges facing FSO is the optical signal propagation through a highly variable medium. For example, atmospheric turbulence produces temporary pockets of air with slightly different indices of refraction.

When I need GPS data for my photos, I prefer using an external GPS logger. This could be a smartphone app or a standalone GPS logger like the Columbus P10 Pro. It offers additional functionalities, and adding GPS data to your photos is a straightforward process in software like Lightroom Classic.

These will randomly change the laser phase-front producing intensity fluctuations and different absorption and scattering. Another challenge is optimal alignment between the transceiver elements. This can be achieved using highly directional and narrow beams of light, tracking errors on the receiver, and generating signal feedback to adjust alignment.

A common solution for either element of the transceiver is to use a telescope-based configuration (either Galilean or Keplerian), replacing some of the single elements with achromats to reduce spherical aberrations. Most receivers may have multiple input ports. These multiple inputs help reduce the effects of atmospheric aberration and atenuations, as well as a way to make redundant paths and prevent blockage of the optical path.

Microscope lenses come in different types that vary based on the magnification's power. · Low magnification objective lens typically ranges from 2x to 20x.

With my Sonys if it doesn't connect on the first try it may take 10-15 attempts to connect. Then it will work unless something goes to sleep, the phone rings or a dog barks at a cat... It is a great idea but I can't use it on a job.

To properly design an FSO system, we need to define requirements including range, data rate, and price. In terms of wavelengths, most FSO systems operate in the near-IR wavelength range between 750 and 1600 nm. The reason for this is due to the lower absorption at those wavelengths, although additional development exists at longer wavelengths (>5 micrometers) .

If you’re concerned about battery usage while keeping Bluetooth active, activate the Airplane mode on your camera. This turns off all wireless connections at once, conserving battery life. The beauty of Bluetooth lies in its ability to re-establish the connection automatically once Airplane mode is deactivated.

For those whose cameras support wireless connections, I encourage you to explore this functionality. Establish connections, familiarize yourself with the setup, and learn how to make the use of them. At some point, you might find yourself in a situation where wireless connections prove remarkably advantageous or discover uses you hadn't considered before.
