The general reccomendation is a 3-2-1 Backup strategy, meaning you have 3 copies: 2 local, 1 offsite. Here's one way: Get a NAS appliance (like a Drobo) to protect against a single disk crash (or just an external disk, with no single disk failure protection) Add an Apple Time Machine to get your 2nd local copy. If Time Machine is not for you, get ...

Does downloading an image off a website when WiFi is strong result in a higher quality image on your device? Signal quality does not usually affect the transmission of data that is sent, though it might result in incomplete transmission. However... Websites often send different data to mobile vs desktop. Some sites do use scripting to send different data ...

TURN OFF WIFI. I struggled with this too but if you disable wifi and reconnect the USB you should be fine.

Luna 3 did something as complicated as you thought: It took photos on a film, processed it in a kind of onboard minilab, and then scanned and radioed it back home in analog way not unlike an old fax. Funniest part was that Soviets didn't have the technology of radiation-hardened film, but Americans did. They used it against Soviets in high-altitude spy ...

Perhaps I'm a bit old-school in this way, but I personally avoid storing my stuff on "somebody else's computer" (a.k.a. the "cloud"). I would just buy (at least) two external drives of sufficient capacity - storage is cheap these days. Back up all your images onto one, and then make a copy of that drive on the other, so you have two copies. Generate a ...

Amongst the myriad online pages documenting the Viking series, here's one which states clearly The Viking Lander camera design was very different from vidicon framing or CCD array cameras. The lander camera was a facsimile camera with a single, stationary photosensor array (PSA), and azimuth and elevation scanning mechanisms. A lander image was ...

I have no idea why someone would recommend this. I suspect it is just superstition. There generally isn't anything important or useful to you outside of the DCIM folder, and you certainly don't get any benefit in copying that folder vs. copying its contents — your computer does the exact same thing either way. Canon's MISC folder is explained at What is ...

If you are talking about JPEG files, then the utility jpeginfo is exactly what you're looking for. It can check files for different types of JPEG errors and corruption and either return an error code (the most useful thing for scripting), or just delete files with errors. I use this as part of my initial file transfer, to make sure everything copied okay ...

Even though the other answer here are already very good, allow me to give a different perspective: In general, no. When you download an image in your browser, it is very likely that this file (the image) will be downloaded through the Transfer Control Protocol (TCP). TCP will split up your image in little packets, and send each of those separately over the ...

You need to install Canon's EOS Utility in order to download the pictures directly from the camera. Canon DSLR cameras do not appear as generic logical drives like some other manufacturers' DSLRs. EOS Utility is included on the disc that came with the camera. Updates are downloadable at Canon's website (under the software tab, rather than the drivers tab), ...

It is not possible to transfer images out of the memory card faster than its maximum read speed. All you need then is a sufficiently fast card reader. With USB 3.0, there is enough bandwidth to exceed the transfer speed of the fastest current Compact Flash and SDXC cards. Lexar claims 500 MB/s top speed which is faster than Gigabit Ethernet (1000 Mb/s = 128 ...

The easiest and faster way to backup is an external drive. 400 Gb is not that much and 1 Tb hard drives are pretty cheap. You could backup on two external hard drives and store one in a different place like a family member, in case (let's hope not) something happens like a burglar. The other option is online storage, but 400 Gb is too much for a free ...

You must install EOS Utility to download pictures directly from the camera. Your computer will not recognize it as a generic drive. EOS Utility will also give you the ability to shoot tethered and control the camera from your computer. Your other option is to use a card reader instead. Does Canon not have a PTP/Mass Storage connection preference? Serious ...

With Amazon Prime you can store an unlimited amount of Photos incl. Raw Files! https://www.amazon.de/b?ie=UTF8&node=12153288031

Keep in mind that the memory card in the camera is just a standard removable data storage device, and the photos on the memory card are just standard files. You don't need any special software to transfer files like this. Take the memory card out of the camera and just use a card reader.

You could turn your device into a Wifi hotspot and then EyeFi can connect to the internet via your phone (or tablet). I don't have any experience with Eye Fi specifically, but presumably its programmed to scan for a list of known wifi hotspots. I would imagine you could program it to find your phone consistently and then once your device is enabled as a ...

Short Answer : you may be lucky ! As you supposed, it seems that you have indeed experienced some corruption(s) during the transfer. Technically speaking, a JPG is made of tiny blocks of pixels called "MCU block" (Minimum Coded Unit). In the case of your image, the MCU has the size of 16*8 pixels (regular sizes are 8*8, 8*16 and 16*8). As one can see in ...

USB mass storage is exactly what it sounds like: your camera presents its storage to the computer as a removable drive. This means you can poke around in parts of the storage the camera would really rather you didn't, re-format with the filesystem of your choice, copy files other than images to and from the camera, and in general treat the camera as a funny-...

Get Google Photos. It's free, it's easy, and once you set it up then future backups are automatic.

No, computers communicate on a bit-perfect level -- even a slight change during transmission might completely corrupt the data, and is protected against using checksums (and retries in case of errors). However, it's possible to have "progressive loading" of images, where e.g. a website might first display lower-resolution images as a quick placeholder (to ...

There are five possible methods that I can think of: Tethering to a Computer You can connect the camera to a computer via USB. However, this limits movement and can be inconvenient at times. This also requires specialized software. This is the cheapest option by far. You will still need a conection to the internet. An Eye-Fi card The second cheapest ...

This is not a bug. On the Canon 6D, USB file transfer is disabled when Wi-Fi is enabled. Try disabling the Wi-Fi first. Good Luck!

It sounds like you were shooting RAW images. These types of files are not directly viewable without special software that understands how your camera works and how to interpret the data from the sensor. They offer a lot of strengths over JPEG, such as being able to adjust white balance and recover from some over or under-exposure much more easily, however ...

The image was corrupted by random bytes of information being lost in the data transfer. You can tell because each time information is lost, the image shifts (because pixels end up missing as it fills each line). It's also not an even number of pixel information since some of the times that information is lost, it causes the color information to get shifted ...

I was searching for something similar and found this GitHub repository, which was someone's attempt to reverse engineer the wi-fi protocol with the Fujifilm X-T10.

Many digital cameras now have built-in WiFi but it is usually tied to the application provided which may be upgraded from time to time. What I suggest doing, if you are looking for such a camera is look at these applications and then read the list of compatible cameras. Most such apps are on the Android store which makes them easy to find. For cameras that ...

On android make sure your phone supports USB otg. Just do a search for usb otg in your app store. You can download an app and it should be able to tell you. Then buy an otg card reader. You'll probably need to find a file manager app that can access it. It's pretty safe to say that the most popular ones probably already have that functionality. No idea on ...

The other answers are correct (no loss in quality of images over WiFi), but I just want to point out: You may have seen that the quality of streaming(!) videos seems to degrade on 'weak' connections. This is however not caused by some of the information being lost during transmission(*): Most video streaming servers today maintain multiple copies of the ...
