Images sizes for DPS and Retina

It says that images should be no larger than 1024x1024px however the retina display is 2048x1536px. So if we are to use 1024px images they will appear lo-res on the retina? Is this correct?

That's an old tech note that should be updated.
The best way to target both SD and HD (retina) devices is to create 1024x768 folios in PDF image format. See Creating multi-rendition articles. Another option is to create both SD and HD renditions, but even if you take that approach, we still recommend sticking to 1024x768 source documents.
For image size, feel free to use high-resolution images for non-interactive images. When the articles are created, these images and all other non-interactive page items are downsampled in the article's image format: JPG, PNG, or PDF. For images in overlays, you'll want to understand the difference between overlays that are resampled (slideshows, scrollable frames, buttons) and overlays that are passed through without compression (pan and zoom, image sequence, and panoramas, along with video and audio). For images in pass-through overlays, create JPG or PNG images in the exact dimensions; avoid scaling. See Best practices for creating overlays.

Calculating image sizes for ibookstore submission

I have the new ipad...so all my graphics look great, but I am having a hard time finding the exact method for determining image size for a book I am submitting to ibookstore. Can anyone point me to a way to calculate the best and largest images for ibooks

For all those who are still confused by Apples image restrictions / requirements...
In the new Template chooser after the recent updates is "Antique". This template has a Chapter background image ( the olde world print of sailing ships in blue litho print style ). This print when opened in PS is 2771 x 1506 @72ppi. 2771x1506=4,173,126 pixels.This implies Apple supply a book which does not comply with its own requirements!
Higher image resolution applied to printed photo inmages, make the image sharper. If for example you wanted to print a wall poster 45inches wide, the image needs needs a higher resolution to cater for the size, BUT the same image used for a 45" poster will print 4.5" wide print on your own printer!
iBA full page is deemed to be 1024 x 748. resolution from Apple is 72ppi. An image with those specifications will be OK in iPad & iPad 2 - but not so sharp on a Retina display especially if zoomed larger on screen
Now it seems 2048 x 1496 - double the original image size is suggested for Retina.
You can change an image in PS i.e. 1024 x 748 and change resolution to 144. PS will double the pixel size as you change the resolution. OK, just change pixel sizes back to 1024 x 748 and reolution is now 144.
That indicates a sharper image which will be suitable for retina display and in fact all current iPad models.
Today my 11th photo book was notified as available in the iBook Store, all my images were pre-formatted at 2048 x 1496 @ 150ppi. ( 2048 x 1496 = 3.063,808 pixels!)
During delivery there were no issues flagged and after delivery no tickets.
So I suggest all those folk pondering images sizes follow my example, which is now proved to be accepatble!
One thing puzzles me though, I dont use all images as full page and they can be masked down to - say - 250 x 200. Should just make an image to fit the size I want to display ??

Recommended Image Size for Contact Pictures?

Hi All,
I want to edit up some family members to attach thier images to my iPhone contacts... Does anyone know what the preferred resolution size is for the iPhone for optimal appearance?
I've tried to do this with outlook before, and I hate the way it dithers the images to a low quality.... I'm hoping that the iPhone doesn't do this and so I wanted to experiment with how they would appear...
But instead of making the images just any random size, I wanted to crop them to the preferred image/pixel size so that my photoshopped images look like what I expect them to show up like...
If you could advise with the documented or known pixel resolution size used by the iPhone it would be appreciated!

Thanks, but I don't believe that the contacts come up full screen do they?
Usually there is a optimal image size for certain things like contact photos and I am just trying to help ensure that all my photos are the same size and don't vary...
I might be a little carried away with how I am formatting them, but just hoping someone already knows this answer!

Photo image size for letterpress card

I'm trying to create a simple card in iPhoto 11 and am having some difficulties.
The various card themes have several layout options. Each option requires a certain size image (or sizes - some layouts are for more than one image).
How am I supposed to know what size of image will fit in each "layout box"?
Am I supposed to just play with the size of the image by resizing a JPG until it fits? Too time consuming - I've tried and I just can't get it to fit. Obviously I missing something simple if this is to be an "easy way to quickly make a card". I cannot find the required image size for the various layouts anywhere, so I'm clearly missing something.
http://support.apple.com/kb/ht1035 tells me recommended resolutions, but they are too big to fit into a card.
NOTE: I'm not talking about cropping an image or resizing it, which I can do.
I just need to know the size these card layouts require! Where is this information located, or what am I doing wrong?
Am I confusing DPI and pixels and resolution and ....?
Thanks in advance for any help!
Best,
Kurt

I'm not clear on whatyou are not clear on
You simply drag photos to the enpty photo frames in the template - there are move and pan controls if you want to change the position of the photo - you can reight click on a photo and select "fit to frame" in most themse if the photo ratios do not match teh frame ratios and yo are losing parts of the photo
the only "resolution" concern you have is that the photos are at least 180 DPI and if they are not you will get a warning
"Note: A yellow warning triangle with an exclamation point in the center may appear if the resolution is too low (below 180 DPI)."
The article you referenced gives Minimum pixel sizes for various uses - if your photo are that size or larger you are fine
The pixel size is shown in teh info window for a photo

Lightroom 1.4.1: Reducing File/Image Size for Web/E-Mail

This should be a simple thing.
I need to reduce my file size to upload it into various things on the web and e-mail and what not. Sometimes it asks for a specific size.
Right now, I'm using the Export function to do this, which means I have to reset the Image Settings each time in order to get to the size required.
Isn't there and easier way to do this, like just type in the image size you want and have the program reset the image proportionately?
Is there a ratio chart for this, like 1000 x 1400 = # of bytes?
This is a function used all the time--I can't believe it's this cumbersome.

(a) How do I know I am selecting the correct pixel size for e-mail? Just keep hunting and pecking until I find the right mix or is there a number combination that works consistently? And if the latter is correct, what is that number combination.
I just can't believe that reducing the MP size to get it in shape for an e-mail "thumbprint" photo is this tough. Even with the 'preset', I'd have to set up a preset for every picture because they vary by MP and the scaling seems to change.
There is no "standard" size for sending images via email. Just make it small. There is a save for email preset in recent releases of Lr. You can download the demo and see what that entails.
You don't have to create a preset for each picture. I don't know what you would say that. Yes, the amount it compress varies with the information in the image, but this has always been the case with JPEGs. You don't have to make an image that is exactly some size. You just have to make it small enough for most MTAs and MUAs to handle. Since there is no real standard for this, just make it small enough for you.
Something like 800px on the longest side, 70-80% quality should do it to find the JPEG compression sweet-spot.

How does one change the font size for folders and/or file lists in the Bookmarks Library?

How does one change the font size for folders and/or file lists in the '''Bookmarks''' Library?
Since the upgrade to version 9.0.1 of Firefox, the Bookmarks feature changes are confusing me. They seem to be confusing themselves as well. The list of bookmarks has changed. The font size is so small that my aging eyes cannot read it without fogging the screen with my breath. Some folders are out of alphabetical order (where I know they were previously good), and some are missing altogether (folders to which I frequently add references).
As for missing or deranged files or folders, was there something that I should have done or now need to do to recover those after the upgrade (or before)?
With regard to font size,
1. there is no “Edit Bookmarks” or like option to edit the list in this version
2. the “zoom” option in the “view” list of functions is greyed out when in “Show All Bookmarks” window
3. expanding the browser window has no effect on font size
4. “Preferences” settings for font size has no effect in that window either, including advanced settings
5. “Help” offers none that I can find.
Can any of you Help?!?

Maybe this extension helps:

What is theoptimal file size for stills, and dpi?

what is theoptimal file size for stills, and dpi?

In video dpi is not relevent. What counts in video is pixels. In FCP most recommendations I have seen is to size your stills so they have no more than 3 times the pixels in your project aspect ratio. For example if your project is 1280x720 then stills should be no more than 3 times the 1280x720. This allows you to crop the stills and still have good resolution. If no cropping is anticipated then they could be the same size as your project.

Skinning and Image size for android devices

I am building a mobile application for both Android and iOS devices. I am using images in 3 different resolutions sets.
The images have been made in such a way that the complete all screens were first designed for 640x960 resolution with 320 dpi. Then I created 3 different sets of images where the images were reduced to 75% and 50% of the 640x960 image size. The images I have now work fine for iPhone 3GS and iPhone 4 and 4S devices. But the 75% one's don't work correctly. This is because the size of say background of view at 75% would be 720 pixels while the size of the Android device's screen is 854px or 800px.
How can I address this issue?

Any help on this?

Calculating max image size for PNG inside an app?

This should be simple, considering that Apple has published a formula for the max image size that an iPad will display. Here are the details ...
I'm creating a "zoomable" image for use in an app. The PNG is fed into the app via an iframe. It's zoomable because the dimensions stated in the HTML are smaller than the real image dimensions. The person looking at the app uses the "finger spread" method to make the image expand. Sounds odd, but it works. Base image resolution is 264px for retina displays.
Yesterday I tried an image that was 2768 x 4221 pixels and the app simply refused to display it. When I changed it to 1000 x 1525 it displayed fine. Problem is, that should not have worked. Apple says the max pixels for an image on iPad cannot be more than "width x height = 3 x 1024 x 1024" That base formula works out to 3,145,728 pixels. Using Apple's math, my image that displays fine has a total size of 4,575,000.
So I'm confused about how to calculate the correct max image size. Apple's formula looks pretty simple but I apparently broke their rule and got away with it. Help?

Arggg.-
The multiplier "3" is only applied on the "1024 x 1024" side, not also on the side where the developer's image width and height are multiplied.

How to set image size for importing photos from a digital camera

I'm using Iphoto 6 and am a novice user of my new digital camera. The camera is set to HQ image quality. Initially when I imported photos from the camera into IPhoto, the images were very large (over 1 meg) and produced good quality 4X6 prints. Now when I import photos from the same camera still set to HQ image quality, the photos are very small (less than 100 kb) after being imported into IPhoto. I think I must have changed some kind of setting in IPhoto that affects the size of an imported image, but I can't find where that is or how to change it back so that the size is not changed when imported. Can someone please help me with this? Thanks!

Dave, thanks for clarifying Toad's response for me - I was just too ignorant to connect the dots from his responses. As you said, there were 2 versions - 1 in the original folder and 1 in data; the original folder had the photos that were 1 mb. We must have pulled from that folder previously to print photos not realizing they existed in 2 places. So when we found these thumbnail photos, we just thought they were the real thing. Where can you go to learn about the struction and hierarchy of the photos in terms of what Iphoto does to an image when you import it? Is it in Iphoto help somewhere? Thanks so much for your help with this, and you too Toad for leading me down the path.
If you're getting the size from Finder, I think Old
Toad's question makes a lot of sense. Is the file
you're looking at, somewhere in a folder called
"Data" in iPhoto Library? That 56k sounds about the
right size for a thumbnail.
If you do a search for the image name, both the
actual photo and the small thumbnail are stored with
the same image, e.g. abc.jpg

Image size for ibooks author

Hi
I am making a book using iBooks author. It will be image heavy. (40-50 images)
I have a few question on images.
1. I do not want the file to be huge or take an age to download so an Apple rep informed me that the images should ideally be no more than 500-600kb per image saved at 72dpi
Forgve my ignorance but can someone eplain to me what this means in terms of pixels? What size (height and width) and resolution (pixels per inch) should I save images so that they can be seen at their best but not be overly large?
The finder window when I try to resize images gives me some standard options. Should I take these? Also if I click on 1024 x 768 pixels as a standard size, the width and height boxes do not change.
I'm a little confused.
Many thanks

This thread is over 12 months old now...perhaps you posted here by mistake. Your problems have slready had rep,ies in another thread, however to answer your question..
No, iBA does not seem to change image size....which is why you see posts about tickets for images size in books held back by the review team.
Consider that Apple gave you free use of iBA. Pages, inDesign and others come at a cost.
If you intend to create other books with a high photo image content, you really need to consider investing in suitable software.
I suggest you search the net for "photo image editors" or similar, dont wait for iBA updates..I doubt Apple will address image sizing and "cropping" can effectively be done using the image mask.
As in all projects be it eBooks, making kitchen tables or building a tree house...its sensible to gather all your assets and ensure they are suitable for the planned use....before starting the construction process.

Image size for playbook wallpaper

What is the image size supposed to be for the wallpapers on the playbook?
I have been tinkering with wallpapers, and read where the image needs to be 1024x600. I have tried files of this size and the playbook cuts off the edges.
I have ended up creating images that are originally 1024x600 and then just expanding the canvas to 1300x1300 to get the image to look correctly. And these only work in landscape. It is a whole different ball game in portrait,
I was able to get 1 image to work both landscape and potrait, but that was a simple circular logo originally scaled to 1024x600, then the canvas opened to 1250x1250. That one worked descently.
Also, an idea for RIM, allow different wallpapers in landscape and potrait. This way we can have an image that sits like we want it so we can see what we want. Just an idea. Thank you.

Optimum Image Sizes for iWeb 08?

I'm trying to find an optimum size for images for an online portfolio. . I have the photos in their native resolution, and I'm wondering what size should I downsize them to for the slideshow view. . . any and all suggestions are welcome and appreciated.

It really depends on how many photos you want to load and what quality you need.
You have to trade of these against the download speed of your webpage.
The iWeb Photos or Albums pages are not the best way to present your work.

Image size after calibration and IMAQ Learn Calibration Template VI in Vision 2012

Hi there
I'm trying to setup a calibration for our fluoroscope camera. I got some pictures of a grid and try to implement a distortion model now.
It works more or less fine. But there are still some problems and questions
1. All my Images are 1000x1000 pixel. After correcting them with the calibration they change their size depending on the Method(937x928 at the moment).
Thereby I lose some information, because some details at the border are cut off. Additionally I would have to increase the size of every image manually for the further processes. Does anyone know how i can implement that the corrected images are still 1000x1000 in size?
2. At the moment I'm using the "IMAQ Learn Calibration Template VI" which I found in an older example. In vision 2012 this vi doesn't exist anymore? Why is this, and how could I implement it now, with using current vi's?
Tried it with the "IMAQ Learn Camera Model" combined with the "IMAQ Calibration Target to Points - Circular Dots", a tresholding a
nd "IMAQ Correction Learn Setup". But the result is much worse this way.
Thanks for your help in advance.
Stefan

Thank you for your answer.
I tried it with changing the border size(tried different values), but the results are still the same (still 937x928). Do I have to set the image size anywhere?
What would be the best way to resize the image? Should I just copy it on a black 1000x1000 square?
And do you have any suggestions how I can build the "IMAQ Learn Calibration Template" with 2012 vi's? I tried it with the code of my first post, but the results are totally different to this: Why this block doesn't exist anymore? Seems to be much easier for me
