I was just sitting in a coffee shop, sheltering myself from the cloudburst
over Tokyo a few minutes ago, and I couldn't help but overhear the
conversation between to girls beside me.

They were talking about mobile phones, apps, and were showing each other
pictures on their phones.

One of the girls said:

> SDカードに映{うつ}す

`映{うつ}す` means to reflect, or project, and I'm only familiar with it in the
sense of a film projector projecting an image on a screen. However, it seemed
they were talking about copying pictures to their SD card.

Is `映{うつ}す` extended in use to mean copying data to a disk? As in, the bits
are reflected on the disk? What are the nuances of `映{うつ}す` that make it
applicable here?

Is this a recent usage of `映{うつ}す`?

question
word-choice
Does 映す also mean "to copy" in some sense?
As far as I know,
[`写{うつ}す`](http://dic.yahoo.co.jp/dsearch?p=%E5%86%99%E3%81%99&stype=0&dtype=3)
is generally used for "copy (homework/data etc)"/"take a photo", and
[`映{うつ}す`](http://dic.yahoo.co.jp/dsearch?p=%E6%98%A0%E3%81%99&enc=UTF-8&stype=0&dtype=3)
is generally used for "reflect/project", but that `うつす` can mean "copy" with
the right Kanji.

Also note a third way of writing with
[`移{うつ}す`](http://dic.yahoo.co.jp/dsearch?enc=UTF-8&p=%E3%81%86%E3%81%A4%E3%81%99&dtype=3&dname=2na&stype=0&pagenum=1&index=00372700),
which means "move/remove/transfer" etc.
