    My ipad is nearly full. The biggest culprit is my camera roll, with nearly 4Gb. I have only around 30 pictures. This seems like a massive amount of data usage. Can I change the resolution of the camera or do something else to relieve the storage pressure?

    Welcome to the forum, something is definitely wrong. I have an iPad 2 with 540 photographs total using only 302 Mb. As far as I know the camera resolution cannot be changed. You don't say which iPad you have. The resolution of the forward facing camera is 960x720 on a 2 but 2592x1936 on an iPad 3. We need more information please. ;)

    Hi thank you for your reply. I actually have around 100 pics not 30, but I still think the memory's too high. It's an iPad 3.

    Is it possible to reset the camera resolution to take smaller photos?

    Hi Eveready - welcome to the forum! :)

    Your iPad 3 has a 5 MP camera and is saving the images as JPEGs - below is a table (from a web search) showing the file size for such a camera - note that a 100% quality compressed JPEG is just 1.5 MB, thus if the 100 pics that you noted above were all acquired by the iPad's camera, then that would suggest their total size should be 150 MB only.

    Now you need to tell us if you are 'importing' images into the iPad from your digital camera(s); if so, then what is the MP size of the camera(s) and are you importing RAW images? As you can imagine, this practice would greatly enlarge your photo storage.

    Finally, you might want to look at the metadata of some individual images on the iPad regarding their size - I use Photogene for this purpose, but other photo apps likely offer this feature. Please post back regarding these questions - good luck!

    Hello thanks for your message. All the pics are taken with my ipad, except one or two which have been downloaded from Facebook. Each pic is between 600kb to 1.8Mb. Why do they vary so much in size?

    Is it possible that the data regarding storage use in my settings is erroneous?

    I also have a few short videos which total around 20 minutes. Is this the problem? I can't work out how to check the size of the video files. Sorry for being so thick...

    Possible, not very likely, but possible. Why not connect your iPad to iTunes on your computer and see what the usage reported there is.

    Now you are talking...videos are memory hogs and 20 minutes will be a lot of memory. ;)

    Ah ok. I'll try getting rid of them and see if that helps. Thank you all

    JPEG is a lossy compression codec that can be set for different levels of quality (the lower the more information lost) - the lossy algorithms will eliminate information differently from each image taken based on its complexity, so depending on the latter & the quality level chosen, the final image size will be reduced and will vary between pics; e.g. just take a photo w/ the iPad of a solid colored piece of paper and look at its size.

    The iPad3 is capable of 1080p HD recording, thus like a HD DVD - although this will vary, a 2 hr HD movie is about 4 GB in size, so I suspect that your 20 mins or so in that video mode would be under 1 GB.

    Probably not as already stated, but worth doing a reset and then rechecking - directions below:

    When an app (or several) are misbehaving, I usually go through the following steps:

    1. Force Close - open the multi-tasking bar (double tap the 'home buttom' or use multi-gesturing and swipe up); press & hold an app until all begin to 'jiggle'; find the offending app(s) and press the 'red circle w/ minus sign' - return to the home screen & try again.

    2. Restart - press & hold the 'Sleep/Awake' (a.k.a. power) button until a red slider appears (may take a few seconds) - move the slider to turn off the iPad; then press & hold the same button until the Apple logo appears - wait for a restart.

    3. Reset - press & hold the 'Power' and 'Home' buttons simultaneously until the Apple logo appears - this may take a longer time, so have patience; the iPad will 're-boot' - NOTE that none of these maneuvers will alter your apps, files, or settings.

    Good luck & please post back your results - Dave :)

    An additional note about JPG sizes.

    Besides the quality setting, JPGs size will vary depending on the content of the picture. The algorithm is smart. A picture that contains few elements, or mostly elements that look alike (color, luminance, etc) will be smaller than a busy picture containing many visually distance elements. For instance, a picture of a blue sky with a few clouds will be smaller than a picture of the crowd at a sporting event.

    Hi T poet!

    Can you please explain how I can discover the file sizes of the photos in the Camera Roll?
    I use iPad 2.
    I can see the file size of photos in Dropbox, but still I want to see the sizes in Camera Roll.
    Thanks in advance.
