Taking screenshots of eReaders

.

I often take screenshots of my stable of eReaders to show clients how documents actually appear. Software previewers are often wrong to very wrong. Also they do not show the actual user experience, like menus and links, on the device. The one problem with device built-in screen captures is that they show you what the device thinks it is displaying (the contents of the framebuffer) instead of the display quality. What you actually see is affected by many factors – lighting, eInk ghosting, brightness, etc. Photographing all of the different screen technologies properly is very difficult.

Many websites show how to take screenshots for specific devices but not all of them in one place, nor where the screenshots live on the device. After you are done taking screenshots, connect the device via USB and (almost) all will present themselves as a storage device.

DeviceMethodNotes
Kindle 1Shift-Alt-gThere is no confirmation that a screenshot is taken. My K1 has an SD card which mounts as Untitled. GIFs are in Untitled (root directory), named screen_shot-xxxx.gif.
Kindle 2Shift-Alt-gScreen flashes once. GIFs are in Kindle → documents, named screen_shot-xxxx.gif.
