IPad 2/ IPad 3 image resolution

Hello,
I am wondering when preparing images for a book what will I have to take in account regards the different resolution of the IPad 1,2 display compared to the IPad 3 display? Would I have to optimize images for IPad3? Will they then be automatically rescaled for IPad 1 and 2 or would I have to make different publications entirely?
Thanks,
Sabine

Other people's threads? I wasn't aware that anyone owned a thread around here.
It's just there for completeness and reference.
- standard screen 72
- iPhone retina 132
- iPad retina 264
I don't know what a standard screen is, or how it would be relevant to the iPad or the OP's question. I also don't know how the iPhone would be relevant for books created with IBA.
At any rate, the pixel density of an iPhone with a retina display is 326 dpi; the pixel density of an iPhone without retina display is 163 dpi.
It's just there for completeness and reference. Who knows what readers may have in mind that stumble across this thread.
Would be good it were accurate then.

You already have my email address. I do not have yours.
Now, to answer the OP's question:
There is no need to create two versions of a book. High-resolution images will be scaled down automatically for display on an older iPad, and images with resolution of up to 1024 x 768 will be automatically pixel doubled on a new iPad, so the visual appearance is the same on either device, except for the amount of detail.
There is a thread here that discussed this at length.

  • Low image resolution in ipad

    I had the new iPad for 3 months now but recently when emailing photos taken with the iPad to friends has been changed from 1936x2592 to 240x320. I couldn't find any settings to change the image resolutions. I am not sure why the resolution is being compress while emailing to people.

    Thanks for your reply
    The issue is the pictures (e.g. employee photos) are saved in Database as BLOB data type.
    The report is loading employee photo into the report (e.g. employee card), but the loaded picture is coming up with much less quality than the original.

  • Handbrake and iPad 2 - image too stretched

    Hello,
    I am trying to convert some home-made DVD's (family etc) to video on the ipad.
    I have ripped using DVD Decrypter, but whenever I use Handbrake too convert to ipad, the image is too squashed (larger black bars at top and bottom).
    All I want it to do is take the original image and convert it into a file format for iPad. Can anyone help?
    James

    Thanks for help. I rip using DVD Decrypter first as I like to have the high quality VOB file for future use.
    In Handbrake, I'm selecting iPad preset. Next to 'source' the resolution is 720x436 so I am unable to change it to 480, however when exporting using these settings for some reason the widescreen file is squashed ie bigger black bars than the original.
    What should the anamorphic setting be?

  • I have photos on my iPad (the first apple device in our household) and then added an iMac and a macbook air. How do I get all of my photos on all devices. Myoriginal iPad has images not on my 2 newer devices and my 2 new devices do not share the same phot

    I have photos on my iPad (the first apple device in our household) and then added an iMac and a Macbook air to our network. We have an airport 2TB back up device.  How do I get all of my photos on all devices. My original iPad has images that my 2 newer devices do not have on iphoto.

    My original iPad has images that my 2 newer devices do not have on iphoto.
    How are the images stored on your original iPad? Are they in the camera roll, in events downloaded using the camera connection kit, or are they in albums synced to your ipad from a computer?
    If the photos are in the camera roll or in events downloaded from a camera, you can transfer them to your iMac and MBA by directly connecting the iPad using USB. Then you can download the photos to iPhoto like from a camera.
    Only, if your photos have been synced to the iPad from a computer, you will have to save them first to the camera roll; then you can download them by connecting the iPad via USB.
    What IOS version has your iPad?
    For new photos you might consider using Photo Stream to transfer your photos between the devices.

  • IPad and images in PDF's

    What's with the iPad and images in PDF's? I've tried a fair number (>6 & <12) and many of the photos, images, maps and graphs don't display except as white (blank) space. I've tried two PDF readers and Safari. I tried to find the specs., but those say the image formats should display. I'm open to suggestions.

    Sure, it's at:
    http://www.wsrphoto.com/web-files/CarbonRiverESA.pdf
    or at the bottom of the Web page at
    http://parkplanning.nps.gov/document.cfm?parkID=323&projectID=19729&documentID=3 6317
    When you extract the images, maps and graphs in Acrobat, many export as 8-10 horizontal or vertical (long axis) images. Acrobat on the Mac has no problems rendering it right, but on the iPad it's blank areas. I've tested other PDF with the same problem.
    On the working side with the iPad I've loaded entire geology guide at
    http://www.wsrphoto.com/mtdnrbook.html
    see link to the "Whole Book" in list of chapters. Every image, map and graph display fine (and make a cool carry along book for road trips).

    No, the site isn't Flash-based; it's a site I've visited on the phone dozens of times. This problem only started occurring a few days ago.
    I'm embarrassed to admit that the site is Popsugar.com, a celeb gossip site that I visit whenever I'm bored.

  • IPad golden image distribution on Apple Configurator

    Hi All,
    Appreciate if someone could shed some light on this.
    We are currently using Apple Configurator to supervise iPads using a "golden image" created from the master iPad.
    As our company expands, there is a need to supervise iPads on other sites using their own Macbooks.
    In this case, we are wondering if there is a way to distribute the iPad "golden image" to the other sites, so
    they could use the exact same iPad settings as ours.
    Thanks for any input

    I received a notice to update my ipad to the latest version of ios7 and when I did the ipad froze with a itune logo and an ipad connector image on the screen..i have turned it off several times but it remains frozen. anyone help with this?

    Unfortunately, your iPad went into recovery mode and must be restored now. There is no getting around this. You need to use iTunes to do this as well. Read this for more instructions.

  • Will there be a fix to the low image resolutions in Photostream between the iPhone?

    Photostream problems arise in the highly inadequate process Apple has currently set up. Once an image is taken by an iPhone they are automatically uploaded to photostream....
    ...This is where the troubles begin.
    Should you then download that newly taken/uploaded image to an iPad (iOs) via Photostream for the purpose of editing, it will have it's resolution reduced automatically (no choice of the user). Converserly, should you download that same newly taken/uploaded image via Photostream onto your desktop/laptop (MacOs), surprisingly it will be the original size in which it was taken w/ no reductions in the resolution.
    WHY?
    Apple, please fix this, otherwise this makes using photostream on my ipad for image transfer/edit (for larger screen real estate), totally obsolete!
    This is very frustrating as this is one of the main reasons why I purchased an ipad in the first place.

    IPhoto on the iPad does support RAW images by the way, and other apps too.
    That depends on what you are calling "support". If you read the iPhoto documentation carefully, you will see, that iPhoto does not do any more than import and store the raw files, but cannot edit the. For browsing the embedded jpeg preview will be displayed, and if you edt the raw image, the edited image will be derived from the jpeg preview. The raw file will never be developed.
    See: Using RAW images with iPhoto for iOS: http://support.apple.com/kb/HT5182
    When you import a RAW image to your iPad, iPhoto will display only the JPEG version of the image embedded in the RAW file. When editing a RAW image in iPhoto, the edits are derived from the embedded JPEG, and saved in JPEG format.
    You cannot email RAW images from iPhoto, but you can share unedited RAW images to iTunes:
    Tap one of the photos you want to share to iTunes.
    Tap the share icon, and select iTunes from the options that appear.
    Follow the prompts to select one or more images to send to iTunes.
    In iTunes, select your device, and choose Apps.
    Scroll down to File Sharing.
    Select iPhoto, and then your photos. Click "Save to...".
    If you made any edits to your image, iPhoto will send a JPEG version to iTunes instead.
    If you import RAW+JPEG images, iPhoto will display and export the JPEG version.
    Nowhere is stated, that iPhoto can process raw images.
    With respect to the photo stream - believe, I am not happy with it, as it is. My post was meant to support your statement.
    The IOS devices are computers, but not yet up to serious, high resolution image processing. Everything is reduced to smaller resolutions and only easy to navigate, if you only work with a small set set of images, not with a large photo library, which is o.k. for web sharing and emailing, but not for preprocessing the images for further edits on your computer.
    Just try to delete 500 images at once from the iPad, when you are running out of storage. You will have to select them one by one, to delete them.

  • Full image resolution in Safari

    Safari doesn't render images at their full resolution, so even zooming won't get you a 1:1 pixel mapping. It helps to "Save" an image to the picture roll and view it in the Photos app, but that's so much work.
    Isn't there a way to view only the image, like desktop Safari can? I just want to read a web comic, nothing huge.

    No, I know exactly what is going on here. Back in december I was away on vacation and was using my iPad to copy all the raw images from my camera SD cards over to a ftp at home. I after the first few attempts I was noticing I was "uploading" a 5kX3k image in resolution, but mobile safari would only have a greatly reduced image uploaded. Luckily I was able to check on a laptop and saw that all my EXIF data was being preserved with the original image resolution. What I believe is happening is that the Mobile Safari in iOS devices have a scaling function on images so that it will preserve some of the image quality without having to wait for long periods of time to load an image. Your images are still the same size as the original upload, it is optimizing the image for viewing because you should not need a 1:1 pixel representation of LARGE images in mobile safari, if you do then you should be using a different device.

  • Best practice for image resolution

    Although my source images files are high quality and look great in photoshop etc when they are viewed within a folio on the iPad the image quality drops. I'm using JPEG high when creating the folio but it still looks pretty blurry. It's OK, but nowhere near as sharp as i feel it could be.
    There seems to be something going during the conversion process that reduces the quality.
    Given that I have some nice, sharp hi-res masters, how should I be putting them in the folios to maximise image quality. I tried creating the folio at the highest quality and there was no difference. I've resaved the images at the size that they will appear in the folio.
    (*bangs head against the wall*)
    Thanks
    M

    I personally have always avoided the use of folders, maybe
    because most of my projects were large merged projects, which
    already contain multiple project "folders." Also, renaming/deleting
    these beasties later on can be a bear, as evidenced by many
    angst-ridden threads in this forum.
    Let RH place them in its own "virtual" Images folder and
    leave it at that. Unless...do you feel lucky?
    By the way, best practice (at least mine) is to name
    everything (projects, topics, graphics) with no spaces, very brief,
    and possibly with 2- to 3-character prefixes to more easily
    identify them (possibly application features, for example). Such
    as: sa_user_cfg.gif for a screenshot of the User Configuration
    window for System Administration.
    Good luck,
    Leon

  • How do I change the image resolution of a photo?

    Hi..,
         I am the beginner in Photoshop.
         I want to change one image resolution from 72 dpi to 300 dpi.
         So, I search and got one pdf for change the resolution of the image. In that they mention, take the "Printscreen" of the image and paste in the photoshop and change the mode(Index - flatten) and change resolution via the "Image -> image size -> Resolution".
         Like that i did, it changed correctly.
         After that I Open one already saved image file in Photoshop and do that same steps but the resolution was not changed.
    So, now how to change that saved image resolution to 300 dpi...??
    Regards.,
    VISWA

    Viswa,
    To find the current resolution of your image, follow these steps:
    With your image open in Photoshop, Image > Image Size (Like you've already done earlier).
    Check the resolution as shown above. If it doesn't show 300, enter 300, hit OK and 'Save' your image.
    Open the file and check again. If it still shows 72, post back with more details of the type of file you're trying to open in Photoshop and if possible, a screenshot so we can help.
