Picture resolution question - newbie

Hello,
I am making a 10 feet by 10 feet (8640 x 8640 pixels) panel. I am using a stock photo that is 4360 x 2912 pixels. I will of course make the picture bigger to fit the panel. My question is: How will the picture look when I have the panel printed at a professional printer? Will it be pixelated?
Thanks for your help.

10 feet by 10 feet is one thing. 8640 pixels is another and they have nothing to do with one another.
>The stock picture is 4368x2912 pixels and is at 300 dpi.
"300 dpi" is incorrect. Image resolution is measured in ppi for Pixels Per Inch. But 300 ppi is also incorrect because the output size is not 14.6 x 9.7 inches, but 120 x 120 inches. Assuming you crop off some of the sides, the final image resolution will be 24.26 ppi. That's pretty low for your purposes. Try to get a higher resolution source. If you can't, then you should explore plug-ins for Photoshop that resample to higher resolution. Genuine Fractals is the one I am familiar with.

Picture resolution question

I am trying to increase the resolution of my pictures to fit a canvas print 100 x 75 cm. Is it possible to do this in Photoshop 10 Elements?

You can also increase the resolution of the image using "Image Menu>Resize>Image Size" dialog box. For more help refer here http://helpx.adobe.com/photoshop-elements/using/resizing.html#main-pars_heading_0

Which setting should I have my apple tv set for picture resolution/quality it takes like a whole day for a movie to download before we can watch it

Which setting should I have my apple tv set for picture resolution/quality as it can take a whole day to download a movie before we can watch it??

The video/audio display settings should set automatically for the best your TV can handle (720p AppleTV2, 1080p AppleTV3).
The download resolution for rentals or playback of purchases from the cloud is set in settings for iTunes store.
Sounds as though you have slow internet. For near instant streaming of video from iTunes store you need around:
Standard Definition     2.5 Mbps
720p HD                    6 Mbps
1080p HD                  8 Mbps
Any slower for a given quality setting and the movie has to buffer as it can't keep up in real time. This might be a few minutes if close to the rated speed or many hours, even overnight.
As pcd251s suggests you could test internet speed (speedtest.net on a computer for example). If that is fine, sometimes the LAN if on wifi can be extremely slow in certain locations - ethernet connections would troubleshoot that.
Slow internet is the common issue here. AppleTV does not have permanent storage and using it to play other content or browse trailers while a rental is buffering can reset the buffering process.   In such cases you might be better off planning in advance, renting in iTunes, letting the whole thing FULLY download and it will then be available across teh LAN to stream from computer to AppleTV under Computers>iTunes library name>Rentals.

Picture resolution or message size restriction

I have an iPhone 3G and am trying to receive picture messages via MMS. I keep getting a message that says, "The media content was not included due to a picture resolution or message size restriction." Is this happening because of my iPhone or because of my cellular carrier? Is there a way to fix this? Thanks!

Your carrier.
Is there a way to fix this?
Sorry, no. All carriers/ISP have size restrictions.

IPhoto Picture Resolution Sizes.

I am wondering if someone can help?
Is it posible for a picture resolution to reduce when stored in iPhoto,either by diliberate means or otherwise?
When reviewing my photos I feel they have smaller resolutions than when downloaded from the camera.
Could this be possible?
Many Thanks.

colin:
Thumbnails will be 360 x 270 pixels in size and you can check that right in iPhoto's Info pane at the bottom of the Source window.
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.

In Elements 8 if I create a Photobook how can I maintain picture resolution?

If I create a Photobook in PSE8, the picture resolution is reduced by PSE so that the resulting print is of poor quality. Is there anyway that I can get around this and/or is this different in PSE9?

Another resolution question.....sorry

Thanks to Zac and Bogie for helping me out with the whole resolution questions but I do have one more....sorry. Do I need to log and capture in FCP in order to import the file into compressor to change the codec or is there another way? Maybe direct from the camera so it doesn;t get any more compressed than it is?
Thanks again for putting up with me
Rick

If you shot on DV, for example, capturing it isn't compressing more. It is what it is. You shot it DV, it is DV. What's on the tape isn't "better" than what gets captured to your hard drive.
Anyway, yes, you have to capture or ingest the footage or have some sort of existing movie file to put it into Compressor. You can't take it from the camera directly.

Change picture resolution

Is there a way to change a pictures resolution in iPhoto? So far, I have been opening the photo in Photoshop to decrease the resolution. My image files are too big after importing them. I know I can change the settings in my camera, but for the pictures already taken.
Thanks

Hi Adam,
I just posted a ? which I think is similar to yours... If you go into "Export" you can pick the size of sending photos to another folder on your computer. jpg, tiff etc, plus if you wish to post them on a website you can also change the pixel size to make sure they are small and not able to be duplicated. However, once they are exported, the photos cannot be used by Pages, iMovie etc until they are re-imported.
I am hoping that in the next 'upgrade' something will be added to make iPhot even more savy for us RAW pic people.
cheers, Diya

Resolution, audio, alpha channel, and backup questions (newbie)

Hello!
Well, after a few weeks of fidgeting around with FCE, I've come up with quite a few questions:
Image/Audio questions
A. What is the best still image size for import to a NTSC DV movie? Is it the 720x480 px (3:2 aspect ratio) standard of the DV image, or the 4:3 ratio of your generic CRT TV?
I know it depends on pan/zoom. This brings up the next question:
B. I have a still image - literally a blue and black two-color image - that I'd like to zoom. It will start out with a very close shot - and zoom out until it takes up around 10% of the screen. The ending frame (the DV size) will be about 10-12 times smaller than the original image. Does this mean that I should make the original 10-12 times bigger (in both directions) than a DV frame?
This clip is essentially an imitation of the opening of the movie "Home Alone", where the screen begins blue, and as it zooms out, you see it's a stylized house, which zooms out to a tiny size. That's essentially the effect I'm going for.
Audio/Video sync issue
C. Some of the clips I've imported from old iMovie projects are a little out of sync. It's not a conversion issue, but an issue with bad editing on my part . So, I have a still image that's about 1.5 seconds too short - it cuts to the next still, which is 1.5 seconds too long. I've added edit points at both ends of the out-of-sync clip, so that I have a 1.5 second clip, with its own audio and video.
The problem is that the audio is perfect, but the video is bad. So, I need to replace the video, without changing the audio. How is this done?
D. Sometimes, I'll end up with either audio or video that's not quite right after importing a movie. However, FCE locks them together. Is there a way to unlock them so that I can change either? Essentially, is there a way to change the audio and video from one clip into two seperate clips?
E. Can I export a single clip or two only? (eg - the same as the "Share selected clips only" check box the iMovie's share menu)
Alpha channel/marquee question:
In one idea I had for this short, I have a still image (and some video) where I'd like to highlight a small area in one part of the image. In one part, it's a small object in the background that I'm highlighting. If you've seen a documentary where they have a group photo, and highlight the face of one particular person, that's the effect I'm going for.
I've made some Photoshop images that can achieve this effect - using a transparent background, a black top layer (at ~40-80% opacity), and an eliptical marquee for the highlighted portion. I then import it, and fine tune the location/size. It works, but it takes a lot of time to talor each shot. Is there some way to do this IN Final Cut Express? A filter perhaps?
In addition: (alpha-video)
is there a way to turn part of a video into an alpha channel, so that it's transparent in the final movie? It's not so much a solid color (as the bluescreen/chroma key technique would need), but more of background. For example, I would like to take some footage of my family walking in front of trees, remove the background, and place an entirely different video/still in. Is that possible?
Backup: FInal question:
I have my source media organized fairly well on my external drive. However, if my drive should die, It would be incredibly tedius to re-link all the files. (I do have a fairly current backup of the external files). Not to mention finding the orignal capture files, re-timing the project, and so on. The project file itself is probably the easiest to back up.
So, how do you back up EVERYTHING? Some projects may have hundreds of files, all over my external drive. Is there some easy way to back up all the files into a single place, like a single folder or DVD, so that if my drive should fail, all the files are in one spot?
I can export them back to a miniDV tape, but I don't have that many, plus they're $5 a pop. I can do this with Toast, but I'll likely end up missing some out-of-the-way files. If only .Mac's Backup had a Final Cut preset.....
I know that's a BUNCH of stuff up there, so if you can help with any of them, i'd be appreciative.
Thanks,
Daniel

Photograph resolution [complete newbie] question

I don't think I'm quite "getting the concept," as they say. The presentations I'm planning to give are photographic, to groups of 10 to 50+ people (in rooms that fit as many). My company has a 2007 projector, 2000 lumens, 800x600 native resolution.
I'm so used to the idea that a larger [print] image requires higher resolution for best results. So, if I have a digital photograph that measures, say 3872x2592, and file size is reduced to 800x600 to match the projector's native resolution, won't the resulting image when spread on an 8 foot screen from 30 feet be anything BUT clear?
Thanks for your guidance.

Depends on the photos. Until YOU see it projected YOU wno't know if it's good enough.
If you'd like to see an example of what 800x600 looks like, open the Display settings in System Preferences, click Scaled, and pick 800x600.

PXI 6224 linear position encoder resolution question

Hello,
I am using Quadrature Encoder connected to the counter 0 of NI PXI 6224. As shown in the picture, the decoder is working at X4 mode, I set Distance per Pulse as 2. The measured waveform looks like the resolution is 0.5.
My question is:
Isn't the measurement resolution equal to Distance per Pulse?
Thanks,
JSI

It's a case of somewhat ambiguous terminology. I've never been real happy with their choice of the term "pulse" for configuring quadrature encoders -- I would prefer a term like "cycle."
The value you wire in should be the distance represented by 1 full quadrature cycle. (Since this will be the distance from rising edge to rising edge on one of the quadrature signals, you can kinda see how someone decided to refer to that span as a "pulse.") If you measure in X4 mode, you'll produce 4 increments of measurement per cycle. That's why you see the 0.5 quantization when wiring a value of 2.
Generally, when I find such ambiguities in meanings of inputs, I run little test cases to help me figure out how things really work. I've found this to be more reliable than counting on my memory.

Pictures resolution in InDesign

So I am not talking about resampling images in InDesign. But I have a question related to the resolution of pictures as InDesign sees it.
I have some photos in JPEG format I want to use in InDesign, not scaled, not anything. All same dimension (pixel resolution). 300 dpi. But one of them, even tough is having the same resolution, it has in the header 72 DPI setup. And InDesign, uses that information and places the pixelated image, scaled up.
The only solution I have found is open the respective JPEG, change its info resolution without resampling pixels, saving as TIFF and import it back in InDesing. Is there not something that would help me explaining InDesign to ignore the 72 DPI seting from the photo?
Thanks,
Romulus

Agreed, but basically I have two options:
a) scale by hand to attain 300 ppi
b) fireup PS to change resolution without resampling
I tought there's a way to shortcut any of these, by scaling without resampling somehow to obtain desired 300 ppi.

Image size related to screen resolution - Questions

Trying hard to get my head around picture dimensions vs quality vs screen/printer resolution, can anyone confirm if what I think I understand is correct.
My Canon RAW images are 3888 x 2592 pixels. If I export from LR a full sized JPEG (at 100% quality) I get an image that is 3888 x 2592 pixels in size. So the questions:
1) If I open the JPEG in something simple like Windows Picture Viewer and hit the 'Actual Size' button then put simply is each pixel in the picture lighting up a pixel on the screen ?
2) If I zoom out then presumably there are more picture pixels than screen pixels so some data is thrown away and there is some downsizing of the image ?
3) If I zoom in then there is not enough data and there is some intrpolation to upsize the image ?
What I'm actually trying to get to grips with is, if i want to post pics online or e-mail them, when to drop the quality a bit to save filespace and when to change image size.
Cheers

Downsample a LOT for email and quite a lot for web viewing. Not only might they not look as good as they should, people will not be happy waiting for a 3000+ pixel image to download to them.
A "full width"
Of course, if someone wants to print the photo, then you need to maintain the resolution and they should know it will take some time to download.
If you want to see what size others use for the web and can't estimate by looking at it on your monitor in a browser, you can find out the dimensions of a picture you are viewing. In Firefox and windows, right click on the photo and select properties.
flickr, for example, resizes to various sizes. Even though you can upload full size images to flickr, you might not want to do so to protect your full-size image from being used.

IMac 24 inch resolution question

Hi there,
I'm considering buying a new iMac and can't quite decide which one to get. Basically I might (very occasionally) want to boot into windows (through Bootcamp) and play a few of the games I've collected. I know the iMac's not great for gaming but it would be nice if it could run reasonably (I'm using a 3 year old laptop at the moment so my expectations aren't that high)
Basically although I really like the look of the 24 inch screen I'm worried that the extra screen size might push games from "just about playable if it's not that new" to completely impossible at the native resolution. So, which resolutions can I select (in Mac OS X and in Windows) using a 24 inch iMac? I've searched far and wide but can't find any reliable information about this. Does the 24 inch iMac support the 1680x1050 resolution that the 20 inch version does? (I'm guessing maybe not, since the 23 inch cinema display doesn't, but it's obviously a completely different piece of hardware so I've no idea really) Which other resolutions? Is there any difference between the options in Mac OS X and in Windows?
Secondly, on my laptop at the moment in the display settings (in Windows for the Ati video card) I can choose to disable "panel scaling" - this means that if I run in a resolution below the native resolution it only fills the centre of the screen rather than the whole of the screen. This avoids the blurry image problem that you get from running at a less-than-native resolution on a flatscreen (obviously at the expense of a smaller picture)
Does Mac OS X support a similar feature? Would I be able to run in, say, 1680x1050 or 1280x800 and only use the centre of the screen or could it only be stretched to fill the whole screen? Finally would this work in Windows on the iMac as well? (It's dependant on the graphics card driver and I don't know what Apple's windows drivers behave like)
Sorry for the mountain of questions but I can't find any information about this at all - it would be really really good if someone with a new 24 inch iMac could have a look and see what choices there are!
Many thanks,
Matt

Hi Russell,
According to various internet sites, the chipsets in two cards available for the 24 inch iMac, the Geforce 7300 GT and Geforce 7600 GT, both support "floating point texture". I can't find any specific references to the implementation in the Apple 24 inch iMac Intel, but I would doubt it is delibrately removed.
So, what good that actually does you is anyone's guess, but yes, it seems to be in there.

Replacement MBP; resolution questions

My previous MBP (17" 2010-ish model) died a week or so back and I'm now in the process of looking into a replacement. I do have some questions I'd like someone to help me out on, all mostly resolution related.
So the first few are related to old software:
I have Photoshop/Premiere Pro CS5.5, which Adobe seems to have given me the finger over in regards to resolution compatability because it's not CS6 or above. Without having seen a Retina Display MBP running any CS5 software (and I'm unlikely ever to at this point) I'm unaware of how atrocious it supposidly looks running on such a machine. How bad/acceptable does it look on a Retina Display MBP? Slightly fuzzy or downright horrid?
Are there any third party plugins or software to bring it Retina support? Same questions applied to Office 2011 and stuff like Google Chrome. How a Retina Display MBP treats my old software is the biggest deal breaker as to whether I simply buy a Retina Display or pre-Retina Display model. I'm not interested in upgrading to CS6 simply because Adobe clearly hates their older customers.
Hardware:
IF the answers to the above are "no" or "you'll have to upgrade your software" and I went ahead and acquired an older Macbook Pro, for this example a 2011-12 15" (even refurbished) model at a 1680x1050 resolution, how does this affect output to an external screen?
Can the external screen display a 1920x1080/20 resolution on a system without a native 1920x1020 resolution like the 17" model did? Using the example machine's native resolution when using it by itself is not a problem for me, but not being able to get the desired external resolution when it's connected to another screen is.
I'd very much appreciate it if someone could help me out here. I don't want to pay a ton of money for something that doesn't apply to the above.

Your replacement came out of a warehouse not off the assembly line.
