Cover resolution-image size

I have no access to the iTunes Store because I'm not in the US and don't have a US credit card.
Now that iTunes comes with Cover Flow I would like album artwork to look gorgeous on my 17" Flat CRT Dell. I'm trying to find an optimal resolution (dpi) and image size for cover art.
I've made some tests with jpeg 500x500 pixels at 105 dpi and with png and psd. Also with 600x600 at 127 dpi. When in the viewer they looks OK but it seems Cover Flow blurs a bit the image when in Full Screen. Any ideas?
Thanks a lot

"You don't have to live in the US to view the US iTunes Store. You can't buy anything from it, but you can still browse it."
What I meant was I don't have access to the ITunes artwork.
But back to my question, don't you feel that when in Full screen mode the image is blured a little?

APPLEWORKS PAINT DPI AND RESOLUTION / IMAGE SIZE

I am struggling to make a 10" x 10" design in appleworks paint using at least 288 DPI. But the max resolution is 2000 pixels x 2000 pixels. This gives me a tiny square, not 10" x 10". The print shop I want to submit to dictates the size (10 x 10) and wants at least 200 DPI. Is there not some way for me to choose a DPI other than 72, 144, 288, 300 or 360??? I love appleworks paint but this is frustrating.
I did a 7.5" x 9" design, using 144 DPI @ 1010 x 1300 pixels and it SEEMED to come out fine, but they want higher DPI, and when it was opened as PNG (in an email) it turned out huge.
What am I doing WRONG?

Hi,
Give this a try and see if this works.
1. Create a custom page size 11x11 using page setup. The extra inch gives you some play with the margins.
2. Create a drawing document then under the Format menu select the Show ruler command.
3. Create a paint frame. Activate the paint frame and change the resolution to 288 dpi.
4. Resize the paint frame to 10x10 by dragging using the frames handles and using the ruler as a guide.
5. When you have completed the drawing save it as a pdf instead of jpg. If you save it as a jpg the resolution will revert to 72 dpi. If you save is pdf, the paint resolution should be maintained at 288 dpi. To save it as pdf use the print command and use the save pdf under the pdf button. Most print shops should be able to handle pdf.
Hope this helps.

Pan and Zoom/Image Size

I have tried the pan and zoom (Ken Burns Effect) in iPhoto 08 but have been struck by the following problems:
1. With the image slider moved all the way to the left, I cannot move an image left-right/right-left to isolate a particular area for a pan start or finish. I can solely move an image up and down.
2. In order to do any panning, I have to zoom into the image. What this means is that to pan I have to do some zooming, i.e., I have to start with a close up of the subject(s) right from the git-go and starting with a close up eliminates areas of the original image. This is not good.
2. My images in the editor (monitor)are complete large in size, i.e. they take up a good portion of the monitor real estate. I thought that reducing photo resolution/image size to 640x480/72dpi would solve the problem but it didn't. I am still encountering the same limited pan ability.
I build very large and extensive slide shows and I now know the limitations regarding music and sound inherent in iLife but I was not expecting a limitation in image presentation capabilities as well.
Just for comparisons sakes, I have used Photoshop Elements 6 (the Organizer) to build slide shows and have not encountered these problems at all.
At any rate, am I doing something wrong in iPhoto 08?
Thanks in advance for any words of wisdom.

Thank you both for your replies. I will definatley try both suggestions.With the cropping, panning and zooming what i am trying to do is this. On a image in previous version of photo elements you were able to select cropping when making a slide show. What I would do is select the image, select cropping. Then I would select a square or rectangular area where the image would start appearing. Then the next select area (square or rectangular) would be where the image would end up at in that. Its was kind of a start & end point for an image. Then to add to this affect you could fade in to the first "cropping selection"so to speak and then fade out in the second "cropping selection". Then your slide show moves to the next image. All in all the transition between photos are a fade in & out affect, whilst the cropping feature let you pick areas of the photo that you wanted to highlight. You could select a small square or rectangle and the image would fade in "out of focus" but the second selected cropping point would be larger and the image ends up in focus.
I hope this makes sense!!! Anyway Steve I will try your suggestion and see how I go!
Thank you

Image Sizes and Resolution standards?

are there any standards for image sizes and resolution for mobile games specifically: backgrounds and backdrops?
i will be porting my game for various cell phones and i'd like to resize images to fit perfect on all cell phone screens, so what would be the best way to do this and what should my image attributes (height, width) be?
i've tried researching on google to see if there were any standards and couldn't seem to find any. if these standards are non-existent what image sizes have you used that you found worked best on various mobile phones?
thanks
Edited by: sassy on Jun 2, 2008 1:49 PM

Google's right, there are no real standards for screen sizes. Some are more common than others, but there are dozens of common screen sizes.
The most common are...
176x208 (same as 176x220, but with no status bar)
240x320
176x220
[Getjar resolution stats|http://www.mobref.com/statistics/world/gDispResolution]
Unfortunately, many phones are slightly more or slightly less than those. If you cover those, you're fairly well off though. If you can make your game resolution independent, that's your best option, though with intricate overlays it may be nearly impossible to do.

IPhoto Calendar Cover - Image size

Does anyone know the preferred size, resolution, and/or aspect ratio for images to be properly displayed on calendar pages and covers? Specifically, I am having trouble with the cover image for the "Modern Lines" template. I can't get my image to fit properly; in most cases it is too large and I can't reduce it any further using the iPhoto contextual menu that appears. But if I reduce the size of the image in Photoshop, then iPhoto still blows it up too large, and it again cannot be reduced sufficiently.
Some documentation on recommended image sizes and resolutions would be appreciated!!
thanks

Nancy:
That particular frame is about 13.4 x 10 inches. I wasn't about to determine the exact size but that gets you very close to including all of the cropped image when the Fit Photo to Frame is not selected. You don't need to crop it in Photoshop, just crop the original in iPhoto to a Custom size, 13.4 x 10.
As far as resolution is concerned the larger the image the better, pixel wise. So always set your camera to the largest size and quality level possible. You can always downsize but you can't upsize.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

New Image Size and Resolution in CC

Hi there.
Ok, maybe i'm missing something, but how do i reduce the ppi's of a given image in the Photoshop CC? Changing it in the image size, in the Resolution field, it acomplish nothing. It logs an entry in the History panel, but nothing changes in the picture. Did Adobe changed how this works, or it's just a bug?
Thank you.

Try setting to real-world measurement, like inches or cm.
Hi Charles, i think that change in cm/mm/in it's the only way to change the image ppi (in my case save/resample it to 108ppi). Can you confirm that this is correct?
Anyway when i go to image size (new panel of CC) the w/h are:
1) grey and always set in pixel with resample flagged.
2) always set in inches with resample NON-flagged (also if my ruler unit is in Pixel).
(and actually that is not new behavior. CS6 behaved same way when width and height were set to percent)
In CS6 and CC i never seen w/h in percent - where is my error?
Many thanks!

Finder Cover Flow image preview size is small, cannot be adjusted and showing empty blank previews in Mavericks

When using Cover Flow the image preview in the main window (not the thumbnail list at the bottom) images appear but only use about 1/2 of the window space available. It is also showing black/blank preview images as I scroll through the files even though they are cached.
I enlarge the Finder to fill my 27 inch display, slide the size adjustment handle (three lines under the file name preview) all the way down as far as I can. The preview only enlarges to a certain point leaving the upper half of the window unused. I wish to enlarge the cover flow preview images to use this window space even if it affects the overlapping or number of cover flow images avaialble in the window. I am assuming this is becasue of the nature of cover flow showing the two previous and two following images to the left and right of the previewed image. As I scroll left and right occsionally one of the upcoming images will appear as and empty preview as well. It's all goofed up.
Hoping for any suggestions.
I have seen articles about using terminal to adjust "flow height" but never anything substainial that seemend like an informed solution.

I also would like to know if there is an answer to this. My landscape photos always display with a third of the cover flow window as blank empty space (matching your screenshot). This seems like such a waste. Is there any way to change the "padding" between the top of the finder bar and the cover flow preview?

IPhone app image size and resolution?

The icon and image creation guidelines specify all of the custom icons and images that I need to create for my app in two sizes: one for the iPhone 3 screen (and earlier) at 163 pixels per inch; and one for the iPhone 4 screen at 326 pixels per inch. While this guideline specifies the image sizes in pixels, I am unable to find any reference to the required resolution in pixels per inch. Should I save the images at 163 and 326 pixels per inch respectively?

As I said it makes no difference to viewing, all things being equal, only to downloading the resultant image if needed for printing.
If you were concerned with print quality you would probably save on maximum image quality -12 in resizing - but up to 90% - save for web - would make hardly a noticeable difference, except for file size.
You can reduce image quality to optimize file size using the slider in save for web and by looking at the before and after preview.
If using jpeg, it’s also possible to select progressive, which loads from top to bottom, without the user waiting for the full image to load.
There really is no point in using 1000 dpi which only blows the pixel dimensions way beyond even the best HD monitor, capable of displaying 1920 x 1080p

Image size and resolution question.

Is an image at W 48.667 x H 32.444 inches at 72 res the same as an image that I could convert in photoshop to 300 res and then the with "Resample Image" clicked off would be W 11.68 x H 7.78 at 300 res for printing purposes? I'm asking this questions because after exporting 200 images from Lightroom 1.4, putting them into an wedding album I realized the images were not at 300 res but the first size listed above. I'm trying not to have to rebatch and have to put them back into the album. I sent the question to NAPP and got this back"
"If you do the math you'll see that the answer is "no."
48x72=3456 pixels; 32x72=2304 pixels
11.68x300=3504 pixels; 7.78x300=2334 pixels."
I did the math and it comes up to 5760 vs 5830. Pretty darn close. So would an image printed out with both settings print the about the same quality or am I missing something?
Thanks
Bob

Bob's question is a common one. And one of the first that most of us struggled to understand. Let's see if I can shed some light to help clarify the matter.
o The image starts out with a given number of pixels from the camera, scanner, or whatever was its source. The resolution only matters when it comes time to print the image.
72 dpi was once a common resolution for displaying on a computer monitor. Today 90 dpi is more common monitor resolution.
o Let's assume that the image is 3504 x 2336 pixels (which I got from his size @ 72 dpi).
o In "image size", if you do _not_ have 'resample image' checked, all you are doing is _rescaling the image. The image resolution is whatever you enter ...
For example, if you enter 360 dpi -- the native printing resolution of many Epson printers -- you get a print size of 9.733 x 6.489 inches
o Let's say you want to print this image at 360 dpi in portrait on 13 x 19 inch paper with a one inch border on the sides. That would make the short dimension of the image 11 inches and the long would work out to 16.5.
To do that you need to _resample_ the image to change the size. More pixels will be made. The resolution stays at 360 dpi. So check the 'resample image' box.
After resampling to get the print size and resolution you want, the pixel dimension goes to 5960 x 3960 (from 3504 x 2336). Those new pixels came at a price, but that is a matter for another thread and a lot of personal bias.
Hope that helped.
P.S. The answer to your question, Bob, is yes. With resample off in PhotoShop, your original images should have gone to 11.68 x 7.787 inches @300 dpi.
In looking at the rest of your original post, it seems that the export didn't work the way that you wanted. Do I read right that the images turned out to be 11.68 x 7.787 @ 72 dpi? Can't help with that as I don't do Lightroom.

Image size and resolution....just when I thought I understood!

I couldn't find this question anywhere else, but I can't be the only one who's come across this:
I have an image in a folder...finder/explorer tells me that it's 638px X 479px, and 234KB.
I open it in Photoshop and go to Image Size. PS says it is indeed 638x479pixels, but that it's 5.4" x 4.06" at 300pp and the "pixel dimensions" add up to 895KB?
(Then, when I place it in InDesign, at 100%, it measures around 2.1" x 1.6"? What's going on? If I input those dimensions into the Image Size dialogue box in PS, without resampling, it would have to be 750.25ppi. Obviously it's not.)
How big is this file really? Which program do I trust...windows explorer or photoshop?

The ppi resolution is simply a number stored with the file to indicate how large to display the image. The height and width in pixels are part of the image data itself. So the pixel dimensions are always the number to trust.
You can open an image in Photoshop and in Image Size change the resolution (ppi) and if you don't check Resample Image the actual image data don't change at all, only the number stating the pixels per inch.
The reason the Pixel Dimensions size in KB is different in Photoshop vs. Explorer is that the file is likely a Jpeg, which is compressed. When Photoshop calculates pixel dimensions, it does this based on an uncompressed file (each pixel=3 bytes for an 8-bit RGB image.) When Jpeg compression is used, a pixel can be much less than 3 bytes, and the actual number varies depending on the image quality and how detailed the image is.
To see this, save your image as an uncompressed Tiff format and the size will very closely match the pixel dimensions. But if saved as a Jpeg, it will be smaller but still the same height and width and the same ppi.
If you are using CS3, it automatically uses a form of lossless compression if saving in PSD format with "Maximize Compatibility" disabled. So in this case the file size will also be smaller than the pixel dimensions number, but if saved in Tiff, it will match that number instead.

How do you change the image size and resolution in photoshop everytime I change the width the height changes my measurements will not stay

Can someone assist me with changing image size and resolution. each time I change the width the height changes and vice/versa?

There's a chain link between width and height. The point is to keep the aspect ratio the same, otherwise your picture would get stretched.
You click on the chain-link to shut that off and you can adjust width and height separately.
Also could you give us your version of Photoshop, what OS you are running it on (Windows 7 for example) and what exactly you want to do with your document?
Resolution is the print term for how many pixels will be printed on an inch of paper. It doesn't apply if your image is intended for screen viewing.

Changing resolution and image size doesn't change result on screen?

I'm using Photoshop CS3. I am trying to change the resolution of several images that will be printed in a newspaper. So the current images are 72 ppi and really huge -- for example 36 x 27 inches (document size), and when I change them to 300 ppi, the image sizes shrink to about 8 x 6 inches, as I expect. But the image I see on the screen doesn't change. So, for example, when I open up the image originally, it's at 33% and the entire image is visible. After I change the resolution, and the image size has changed accordingly, the image still appears the same and it remains at 33%. Shouldn't the image shrink on the screen since its size has shrunk? Or if it remains the same on the screen, shouldn't the percentage shift? I mean if the document size is now 8 x 6, it should be able to be displayed at 100% and not fill my whole screen... I'm so confused. Thanks...

gradded,
The "Document Size" area of the Image Size dialog is just to indicate the size (in inches) that your document will be printed. The ppi adjustment has nothing to do with what is displayed on your monitor. Your monitor doesn't care anything about ppi. The monitor contains a certain number of pixels and after you change that ppi setting, the monitor will still have that same number of pixels.
As long as you leave the "Resample Image" box unchecked, your image size (Pixel Dimensions) will not change. You will see no change on your monitor. If you check the "Resample Image" box, then your image size (in pixels) will change.
Hope this helps.

Image Size reduction and gain resolution... Help?

I have searched the forums and seen plenty of talk of Image Size and resolutions but havent stumbled upon what I need.
Hopefully someone will be nice enough to help me or to link me to help?
I have a large photo (3456x2304) but it is at 72ppi.
I am trying to use it as a very small image (200px or so) but I need it at 300ppi.
I keep going into Image Size and reducing its dimensions to the size I need and marking 300dpi.
Problem is when it resizes it gets horribly pixelated!!!
I cant figure out how to use the image size and/or crop tool in order to reduce the dimensions and not lose quality.
Best work around I have found is to reduce it to about 750px 72ppi and then in illustrator contract the image to the actual print size while gaining resolution...
Any help would be greatly appreciated.

There is a relationship between image size and ppi (resolution) that can not be changed. Here is an example from the web titled "understanding resolution".
Let's say you have an image that is 9 inches wide and 6 inches high with a resolution of 240 pixels/ per inch (8.9mb file). If you change one of the values the other two will change (resample image turned off). In this example if you changed the width to 6 inches the height would become 4 inches and the resolution would become 360 ppi.
So if you are taking a large image and reducing the size the ppi has to go up. There are the same number of pixels in the picture, they are compressed into a smaller space. The article says this is because a digital image has no absolute size or resolution. All it has is a certain number of pixels in each dimension.
Hope this helps.

Image size & resolution

Why is that when I change the resolution under image/image size the width and height change?

Thank you so much, resample image was unchecked. I've never had that problem before, so I thought I might have clicked on something.

10.9.3 finder cover flow doesn't save image size

I went from Snow Leopard 10.6.8 to Mavericks 10.9.3. Everything went ok, but I have one annoying problem though.
Everytime I open a cover flow window in Finder I have to resize the image preview section. The Finder window size is saved,
but not the actual image size of the cover flow. It always goes back to a default, very small, size everytime I reopen the Finder window.
Didn't have this problem in Snow Leopard. It worked great. I just know one other person with the same problem. He just bought his MacBook Pro with Mavericks
and I am on a late 09 MacBook. So it shouldn't be a problem with just my Mac and Mavericks.
So my question is;
Will there be any solution to this soon? Maybe a program update to be released, regarding this issue?
Thank you for any feedback!

Ok, more information for anyone that might care. The wake-up seems to be the familiar dark wake in order to go into hibernate mode. Except now, it's a death wake. Looking at the logs, I see that it happens exactly 70 minutes after sleeping, even though hibernatemode = 0 (which shouldn't hibernate at all!)
So my power settings look like this:
Currently in use:
standbydelay         4200
standby              1
halfdim              1
hibernatefile        /var/vm/sleepimage
darkwakes            0
gpuswitch            2
disksleep            10
sleep                10
autopoweroffdelay    14400
hibernatemode        0
autopoweroff         1
ttyskeepawake        1
displaysleep         2
acwake               0
lidwake              1
standbymode is 70 minutes, what a coincidence. I'm going to try setting it to 0 and see what that does.
