access the content of the sd card through a usb cable plugged into the camera as if it were a mobile

Is it possible to access the contents of the sd card via a usb cable plugged into the camera on a canon eos550D? I ask because I need to change the name of the photo as soon as I take it, and I can't go around removing and putting the card so many times to change the name. It would be something like with a mobile phone.

dostoyevski,

Your 550D has a USB port, but what is the other end of your USB cable going to be plugged into?

a computer? or a mobile phone?

You'll need some kind of transfer software. On a computer, you might look at EOS Utility. That's a Windows program.

If you want to download to a phone, you might look at Canon's Camera Connect.

If you want to change the name of the file and upload it back to your camera, you'll need to follow the camera's file structure and numbering protocol

ok, thanks! I already did it by usb. But, can it be done by wifi? (without wires) (on a computer)

dostoyevski,

Apparently you can use EOS Utility to send images from the camera to the computer wirelessly.

Here's a set of instructions for doing that with the Canon 90D.

While some of the steps may be a little different for your camera, the basic procedures should be about the same.

I do not know about reversing the process and sending images back to the camera.

I am not a computer person, and my knowledge is very limited.

None of the cameras I've had so far actually required a transfer program when USB-connected. The program just theoretically (to some degree or another) streamlines the transfer process by hopefully keeping track of what's been transferred before and what's new.

All my cameras just show up as a storage device when I plug them in. You can usually specify how they're to appear - As a camera, drive, whatever. They're "drives" and I just copy from them. I've never had a reason to copy anything back to the camera, though.

Len,

If I understood dostoievsky correctly, he wants to transfer or copy an image from his camera to a computer or mobile device on the fly, so that he can rename them and then transfer them back to his camera without ever taking the memory card out of his camera.

I don't know how you could rename the files in camera because there are no keys to input letters and numbers.

I personally think that the easiest way would be to take a bunch of photos, take the card out of the camera and put the SD card into a card reader plugged into a USB drive on your computer - but that's not what he seems to want to do.

You could create a new folder on your camera, and transfer all those newly re-named files back into your camera in your newly created folder, but I think you have to adhere to Canon's file numbering system in your re-naming process.

dostoievski needs to read up in his manual about how to create new folders on his camera, and how Canon uses a sequentially numbered file structure in their storage process.

I personally don't know why a person would want to undertake this kind of laborious process, but that's just me.

dostoyevski,

Yes, you are partially right.

Canon EOS 550D (EOS Rebel T2i / EOS Kiss X4) Specs

Connectivity

USB

USB 2.0 (480 Mbit/sec)

HDMI

Yes (HDMI mini)

Wireless

Eye-Fi Connected

Remote control

Yes (E3 connector, InfraRed)

Eye-Fi was a company based in Mountain View, California, that produced SD memory cards with Wi-Fi capabilities. Using an Eye-Fi card inside a digital camera, one could wirelessly and automatically upload digital photos to a local computer or a mobile device such as a smartphone or tablet computer. The company ceased business in 2016

You'd have to buy Eye-Fi cards on the used market like ebay or something.

I have no idea how Eye-Fi works and have never used it.

But i don't know if it requires any configuration or any software for conecting it to the computer, and the manufacturer does not specify anything either

I used it once, before I bought cameras making hotspot. 550D is unable to do it.

EyfeFi card is just a SD card from camera’s point of view.

To download pics to the PC maybe phone, you need a proprietary tiny free SW, from the card vendor.

Not sure, if this project is still living, check their web.

There was also another vendor, I think Fuji or what.
