To add a bit more flavor to these other answers, here's several copies of a picture that I just took: Unikitty 1 - Resized ?x400px, no change in quality Unikitty 2 - Resized ?x400px Quality 50% Unikitty 3 - Resized ?x200px Quality 50% Unikitty 4 - Resized ?x200px Quality 5% On my computer I have stripped the metadata with exiftool --all=, and computed ...

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 ...

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 ...

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 ...

It is possible that you are viewing the images as they are being downloaded (photos stored on cloud app like Google Photos) or it is fully downloaded but the software you are using to view the image hasn't completed rendering - so you are seeing an image in progressive rendering mode. To answer your question, No the quality (i presume you meant the speed) ...

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 ...

No. Digital files, contrary to their analog counterparts, are always perfect copies, so the image either fails to download, or is downloaded perfectly, every single time. Same thing applies to transfering them between mediums (SD to disk, pendrive, CD, ...) or creating copies. Corrupt copies are possible, albeit very improbable, on some cases, but they are ...

What is the most likely problem? I'm thinking the cable has given up the proverbial ghost... Since your camera seems to be otherwise functional, the likely cause of your problem is, as you've already noted, most likely a damaged USB cable. This is a common problem, and the solution is to use a different cable. Even if the cable is not the problem, ruling ...
