I bought a flashair which is an SD card made by Toshiba. It has a high function that we can connect to it from our smartphones or PCs. We can download photos on the SD card so as not to unplug it. Photos by a camera are more beautiful than ones by smartphones, but I usually use smartphone since it is the very easy way. I think we can use a camera easily by using the flashair. I hope I will use a camera and take many beautiful photos.
