Resolution DPI

I'm new to Aperture and have a question I can't seem to figure out. It may be a camera setting even but how do I shoot into Aperture so that the Master/RAW image is opened at 300dpi. I'm using a Nikon D80.
Sorry if the answer is too obvious.
Thanks in advance

I am opening my images in Adobe Camera Raw and they always open in 240 dpi. There is an option to change the dpi there but if I increase it to 300 is that a bad thing? I thought that increasing the dpi loses information.
Until the final step of sending an image to a hard copy print device, all that matters is the total number of pixels. If we reduce the total number of pixels we do lose information. And if we increase the total number of pixels from the original capture we do not really add image information, so we are creating a sort of false resolution.
E.g.300 pixels x 600 pixels is 180,000 pixels, whether at 300 ppi or 100 ppi. When sent to final print 300x600 pixels @ 300 ppi will print a 1"x2" print; when sent to final print 300x600 pixels @ 100 ppi will print a 3"x6" print (but at the lower 100 ppi resolution).
What is risky is arbitrarily increasing the number of pixels ("uprezzing"). E.g. in the 300x600 original pixels example we may want a 3"x6" 300 ppi print. So maybe we reset the image data to (3"x300 ppi = 900 pixels) x (6"x300 ppi = 1800 pixels), which equals a new total of 900x1800=1,620,000 pixels. That is an arbitrary 9x increase in image data!
Interestingly, unlike with film scans, for printing purposes we often can get away with uprezzing well shot DSLR images by 2x or sometimes even more. However uprezzing is definitely something to be avoided except in very specific, controlled situations.
There are no dots in digital files, only pixels, so dpi is a misnomer until the file gets to a hard copy output or input device.

Ideal resolution (dpi) for standard 24"x36" posters?

There has long been debate at the various studios I worked for regarding ideal poster size resolutions.
For 24"x36" posters, some studios work in full 300dpi. Others find that resolution too demanding on the computer, and work at half-size (150dpi). Then I was told printers will print movie posters at 72dpi so anything above that is wasted anyway.
So I come to the experts... what resolution are most 24"x36" Hollywood posters done in?
Thanks!

If it goes to a sheet fed press, probably never. Most color printing is done in China now, and though they do remarkable work in the high resolution area, I suspect 175 would be a fair working resolution. I say this as one previous poster here stated 150 was fine for him. But he did not state if that was as a designer or if it was as printing company. At 175, this may be the line count the poster is printed at, and a possibly good match for both party's needs. And if the poster prints at a lower resolution, then both parties have a higher quality file than can be lowered for printing. Thus, you have a very good chance of a win-win situation at this point, and everyone is happy.
If I remember right, at 8 bit, 2' x 3' in 300 ppi is around 150 mgb. So the lower resolution makes the file a lot more managable before the CMYK separations are done.
I hope all goes well with the poster design.

Sorry, my bad for not being clearer with my question.
What I wanted to know, essentially, was if there was any point working in a document that was 24"x36" @ 300dpi? In other words, is it likely that I will EVER be printing the poster at that size and resolution? Because PSD's can get ridiculously big very fast at those settings.
Without knowing what the printing method will be in the end... heck, the client may want to handle the printing himself... my question pertains more to the working file and how much resolution is considered overkill.
Has a movie studio ever printed a 24"x36" poster @ 300 dpi?

Display resolution (dpi)

Hi,
I was doing some scaling from my private pictures and wanted to fit the size perfectly on my mbp display.
So, I knew, I have a native resolution of 1680x1050, but there is a third factor: The dpi.
The "standard" is 72 dpi for all pictures you want to see on a display, but I know, the display of the mbp has got a much higher resolution than 72 dpi.
Is there anywhere a page with the exact data of my screen?
I've read something about 120 dpi, but I dont know, if this is right.
Thank you

Good memory! 1680 pixels / 14.5625 inches (the width of my display) = 115.36 dpi.

LCD Projection & photo resolution / DPI

I am creating a slideshow from some older photograph which I intend to show with an LCD projector or through a standard TV set. I am scanning the photos into the computer. Is there an ideal resolution that I should use or at least a general "rule of thumb" that I can apply for this sort of end use?
Thanks

So, there is no reason to go through the extra step of resizing the photo to 300 dpi before moving it into a 300 dpi document? Photoshop Elements does the resize for you without losing image quality?

Urgent Question about Photobook resolution & dpi

I'm here trying to create a photobook 11" x 8.5", i notice the minimum requirement for a 11" x 8.5" photobook is 2010 x 1558 with 180 dpi, the images i have are 2560 x 1920 with only 72 dpi(look up from photoshop) , when i put the images into the photobook template there is no warming symbol (the triangle logo), does that mean that my images are o.k? if i want to add something to the images by using photoshop and set as 180 dpi, would it effect to my images quality?

Welcome to the Apple user discussion forums
Ignore the "dpi" of your photos - dpi really have no menaning until you actually print an image - if you are interested in details read +The myth of DPI+
I would not change the dpi in Photoshop - the 72 is the resolution of your screen and has no effect on the printing - the dimensions of the page and the size of the photos is what is important and your are fine - it will print at 225 dpi and crop just a hair off the 11 inch direction

What is the recommended image resolution (dpi) for best result in a A0 (plotter) printing?

Is the 300 dpi resolution good enough (images>24bit>1680X1050 pixels) for best printing result in A0 (plotter)?

It sounds almost a trick question. 'How can I use a pen plotter with bit map images?' sort of thing. Plotters are designed for vector artwork, and more suitable for use with Autocad than Photoshop. However there are apparently workarounds, but the question might be more like 'how to convert bit map image for pen plotter?' rather than what resolution you need.
Is there a particular end use for this graphic that requires a plotter? Like laser etch, wood cutter etc. or is it just that the pen plotter can manage A0?

Resolution/dpi of safari?

With the new rMBP capable of displaying something around 220 dpi, what is the top resolution or dpi that Safari is able to produce? Is it site specific or does the browser eventually scale down images?
Basically if you upload an image to a site at a resolution of 220 dpi, will it show up as 220 dpi on any display that can support that resolution?
Thanks for any help or info about this.

Do you know of any display which can display at 220 dots per inch. For many years most displays were about 3 dots per mm but I am not sure if this has changed.
Do not confuse the stated screen resolution with the capabilities of the display.
In general images are so many pixels wide and they normally (not always) contain extra data about the width they should be displayed at.
Browsers try to combine this with user preferences. In general they will scale to reduce an image to screen/window width or less if directed by HTML or CSS in a web page.
Proper web servers do not alter images.
Browsers display images better and faster if they don't have to scale them but you may want to use a higher resolution if the images are going to be printed.
What are you trying to do?

How do I increase the resolution (DPI / PPI) of a scanned image on my iMac?

How do I increase the resolution of a scanned image. i currently am using a new All in one HP Photosmart 5512, I've installed all the proper drivers have a usp cable connecting the AIO to my iMac. I am running OS 10.7.4.
The HP Utility icon only allows me increase the file size (image quality) not the PPI/DPI
Thank you in advance for any help
This question was solved.

Hi,
You may change the Resolution using the HP Scan application as following:
Click HP Scan at the top and then click Preferences.
Within the launched windows select the required Resolution.
close the Preferences window and perform the scan.

Pages resolution, dpi, RGB, CMYK

I've been doing some ebooks etc. with Pages, getting lovely results. I started to use it instead of Photoshop or Illustrator\InDesign to make CD and DVD covers. But with different replicators, different requirements... some are now printing in RGB, some in CMYK (a problem with Pages I'm thinking).
Has anyone tried to use Pages as a replacement for the Adobe apps? I'm trying to figure out what the actual resolution is, and if there is some way to export a PDF that will be printer friendly across the board. (I know this is probably fantasying, but if one doesn't ask...)
I've noticed that exporting as a PDF gives a good PDF if opened by any Mac app., but Adobe was opening it in CMYK and there were weird things happening, black bars appearing, odd things.
Any suggestions about how to use Pages to do graphics (mainly DVD or CD covers) that a traditional printer won't sneer at, I'm all ears ...
Ben

Ben...
Peter's right, and that Pages FAQ site looks like a terrific resource. The only help I can give you is to recommend you do a sample test with your printer...create a quick document that includes some of the pitfalls anticipated, and heed the advice about PDF/X from the other site. I too have run into quality issues with how drop shadows are rasterized.
Your success is COMPLETELY contingent on the type of printing you're anticipating doing (offset vs. digital), and even then, the PRINTING ENGINE/PRINT CONTROLLER used by your print shop to "rip" your PDF in order to print it. And working with them through a test document is the fastest way to determine how the workflow from Pages to finished deliverable will look.
So....do you test layout in Pages, export as a PDF, send it to the print shop, and they'll "rip" it, and can send you back an updated PDF...if they're local...ask for a sample hard copy. Compare the two digitally and/or hard copies before proceeding.
A secondary bit of counsel I can offer concerns the IMAGES you'll be using in your layout. If you're including any rasterized artwork (photographs, or rasterized logos and other artwork), you should convert ALL THESE IMAGES from RGB to CMYK before you proceed with your Pages layout. I think you can use AUTOMATOR to do a batch conversion.
Presuming your figure out a workflow with your print shop that doesn't cause them undo grief, and you're happy with the quality of your CMYK images and the test document, you should feel like you can move forward with confidence.
However, snags you might encounter would likely have something to do with the things Peter addressed by linking to the article at the Pages FAQ blog.

How to increase the image resolution dpi

Hi,
I am new with JAI, I am trying to increase the resolution of an image from 96dpi to 200dpi.
I founded "scale" operator, but this one resize affect only the with and the height of an image and the resolution remains unchanged.
Could you help me, thanks.

iPhoto has no way to do that. You'll need an external editor for the job. Not all have the capability. I know Photoshop has.
You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.

Hello! How change image resolution (dpi/inch) with Automator!

I have some images to combine in a PDF. The resolution of images is different so the PDF has different size of pages.
I need to modify the resolution using Automator but... how to do it?
Thanks Sterfano
PS sorry for my bad english language

Have you tried setting it up using "crop images" - you can specify the size.

What Print Resolution for Epson R800?

I wonder what the value for "Print Resolution" in the Printer module should be to print with an Epson R800 on glossy or luster paper at the highest quality settings (Photo RPM).
I would rather not have LR do any re-sampling... but given it asks for a resolution, I am unsure what is the best value to provide.

Antonio,
LR is limited to 480 dpi, not printer ppi:
"This number of ink drops a printer can put on paper is called the printer resolution dpi. So if a printer has a resolution of 1200 dpi but requires 16 drops of ink to display a color, the actual resolution is much lower. Since ink drops are used in both directions (length and width: 16 drops made up of 4 rows of 4 drops), you could say that the effective resolution would be 1200 divided by 4 (or 300) dpi. Practically this isn't entirely true since modern inkjet printer can spray tiny ink drops that overlap each other. Roughly you can say that the higher the printer dpi, the higher the print quality, but it also depends on how the printer forms the dots on paper."

Specific pixel size & dpi

Is it possible to set specific a combination of size (in pxls) and dpi? (in Illustrator CS5)
I need to create a .png document which is 16x16 px and 96dpi. The ability to chose the dpi size when setting up a new doc is very limited.
The only thing I've managed to do is create a 19x19 px 72dpi image, export it "for web" and then take it into photoshop and change the dpi to 96.
Is there a better, easier way? Also, we're considering upgrading to CS6 - are these features better in CS6?

Bidds, you are confusing DPI (Dots Per Inch) with PPI (Pixels Per Inch).
DPI is a technical specification of the output or input of hardware devices like a printer when you print, monitor when you display your digital image, scanner when you scan to make digital images, and etc. For printers DPI specifies the size of the ink drops when printing. For monitors, DPI specifies the monitor's resolution or in other words the size of the monitor's pixels. The term DPI for monitors came from the use of the CRT displays (those heavy monitors and TVs in the past with big tubes) which are no longer in production. These displays used guns to shoot light at the back of the screen with variable size dots and the term DPI perfectly described the monitor resolution used. Today there is only LCD displays on the market and thy use fixed cells which define the monitor resolution. Because the cells are fixed, for describing the resolution of LCD monitors, people mostly use the term Pixels Per Inch when they want to describe the size of monitors' pixels (cells). And this can cause some confusion that you are experiencing.
PPI is an attribute of a digital raster image. It specifies the output resolution of a raster image or in other words how large the pixels in the digital file will be output.
In Photoshop you are setting PPI not DPI.
Illustrator is a vector program. Vector graphics are resolution independent (have no pixels) and don't have PPI attributes. The PPI attributes are valid only when creating a raster image for outputting to devices like printers. Printers can print the pixels of your digital image with different size, and thus the image with the same number of pixels can be printed with different sizes. Monitors however don't use PPI settings of digital files to display images, instead they use the zoom level specified by the user using software, and by default the software programs (your browser for example) use 100% zoom which fits one image pixel to one monitor pixel. Because different monitors have monitor pixels (cells) with different sizes that cannot be changed on LCD screens, a digital image with the same number of pixels will be displayed at different size at the default 100% zoom on different monitors. Also have in mind that certain elements like software interfaces cannot be zoomed (changed) by the user.
So, the DPI mentioned in the link you provided does not mean PPI and it doesn't suggest in anyway that you should set PPI in Photoshop or any other program when creating images for the web. You got that wrong. It is only telling you that monitors with higher resolution (DPI) will display your image smaller so, you may want to make the image larger (with more pixels) and vice versa. The PPI settings in a raster image are simply ignored for display on monitors and thus on the web. That's why you don't have an option for PPI in Save for Web and devices. Whether an image with a certain number of pixels is 72, 96, 300, 1 million or 1 PPI (pixels per inch) this will not make any difference when displayed on the web.

Images: Different screen resolutions, howto ...?

As you might know, there are several screen resolutions, used by different devices (iPhone 3G/3GS/4, iPad). You might take a look at: http://stackoverflow.com/questions/2993006/designing-for-varying-mobile-device-resolutions -i-e-iphone-4-iphone-3g An example: If i would like to build a generic app, with optimized images for the iPhone 3G/3GS, 4 and iPad, how can i implement the images within my application with the use of different screen resolutions (dpi). 3G: image_low_res.jpg, 4: image_high_res.jpg etc. Is there a better overview for iOS devices showing the exact resolution (dpi)?

In objectiveC/XCode, you would have two images - one at standard size, and one at double resolution for the retina display. The double-resultion image has a '@2x' suffix just before extension. The OS automaticallt uses the correct image depending on the type of phone (i.e. it uses the @2x image on the iPhone4, and the original image everywhere else).
Of course this doesn't help us in Flash. I don't think Adobe have built this feature in to the packager?
Perhaps a good way to achieve the same results is to have the application detect the phone type on startup/constructor by checking the screen size (Capabilities.screenResolutionX/Y). Then, whenever you need a screen coordinate, distance or an image, you have a custom class (probably static methods) that you ask for this information.
It seems like a lot of work, but if you are really keen on supporting the retina display, this is probably your best bet!
Psuedo code:
// Two images in the library
// spriteA.png
// [email protected]
// All my coordinates are measured in original iPhone coords (320x480)
// I am now asking for a point in the middle of the screen
// If I am on iPhone4, the resulting point will be (320,480)
// If I am on iPhone, the resulting point will be (160,240)
var p : Point = ResHandler.createPoint( 160, 240 );
// Now I grab my bitmap
// If I am on iPhone, the resulting bitmap will be spriteA.png
// If I am on iPhone4, the resulting bitmap will be [email protected]
var b : Bitmap = ResHandler.createBitmap( 'spriteA' );
// Now place the bitmap
b.x = p.x;
b.y = p.y;
addChild( b );
// Now move the bitmap by 100 pixels.
// If I am on iPhone the resulting distance will be 100 pixels
// If I am on iPhone4, the resulting distance will be 200 pixels
var d : Number = ResHandler.getDistance( 100 );
b.x += d;
Hope it helps

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?
