HT201493 Resolution on photos is bad

Resolution in photos is bad how do I fix

You would have to specify the final print size as it would appear in the yearbook. For example, if the print were to appear in print @ 3 X 2 inches, even at normal printing resolution of 300 DPI, this would be a smal file in overall pixel dimensions. 900 by 600 pixels to be precise. This would have to be down sampled heavily from a normal camera file of perhaps 2500 X 3800 pixels, (or thereabouts). A photo uploaded to the web is normally only at a resolution of 72 DPI ...!
Basically you would take the size of the image, in inches, as it will appear in print, then multiply those numbers by 300 (the DPI or PPI for print). A 5 X 7 inch print would of necessity be, a 1500 x 2100 pixel file.
You should probably copy a couple of photos and practice with the "image" > "resize" dialog box. A hint is when you have to resample down, set the method at "bicubic sharper".

  • Can anyone help me fix the resolution on photos?

    I need help with picture resolution immediately. I work the school yearbook and photo resolution is the only thing setting me back fron publishing pages. Photos saved in my computer don't have 300 resolution and i need them to be. When I changed a photo to 300 resolution the photo still shows up as unacceptable resolution and then I am unable to publish my yearbook pages. If anyone knows how to fix this problem please let me know.

  • 24"iMAC optimal screen resolution for photo processing

    I have a 24" iMAC (matte) and do mostly photo editing. What is the optimal screen resolution for photo processing work?
    thanks
    a/d/

    All Screens are 72 dpi (dots per inch- in reference to pixels) no matter what screen resolution you use. The only difference the screen resolution will make is the size of the photo when you are viewing. Higher resolution means the picture will take up less space in you work area, but you will most likely have to zoom in to edit finer areas. Lower resolution will cause the picture you are editing to take up more of your work space and to see multiple photos side by side you will have to zoom out of fron the photos. So, really the choice is up to you.
    When creating the original document, this is where you need to monitor the dpi. The higher the dpi, the clearer your photo will look in print. A high dpi also means more disk space is being taken up by the photo. Generally a good dpi for print is 300 dpi. Anything that is only purposed for a screen based project (i.e. internet logos) should be saved at 72 dpi. Why use disk space and cause your pages to take longer load if no one will be able to tell the difference on screen between 72 and 300 dpi?
    Hope this helps!

  • What is the ideal resolution for photos when creating a photo book in iphoto?

    Can you tell me what is the ideal resolution for photos I use to create a photo book from my iphoto library? 

    The DPI depends on the size of the image to be printed by the image file.  A 639 x 960 image could print a 3.5  x  5 photo at 180 DPI.  This website explains it further: The Myth of DPI.  
    So use the smaller photos only in the smaller frames on multiple photo layouts for best results.

  • How do I get full resolution from Photo Booth?

    My camera is 720 p but pics taken with Photo Booth are only 221 kb. Is this right? Is there a way to get higher resolution from Photo Booth?

    Yeah, that sounds about right for a camera of that pixel count.

  • What's best resolution for photos

    I take very high resolution photos, 1mg files with 2000 by 3000 resolution.  It's a hold over from when I worked in publishing.
    Is this overkill, or does this allow me to get the grain in a hardwood floor, details in a piece of masonary, detials that are in shadow ect. I know how to capture this with my 35mm film camera but I am using such high res to make sure I get the most detail, but I notice a lot of, well almost all photos I get else where are like 640 by 780 pixel with a 64kb file size. Am I comitting overkill or are they comitting underkill, or is the best answr somewhere in between?
    Isn't the more information you have the more detail you get and the more information you have to manipulate.  When I use to work in publishing we used as high resolution photos as we could. We would send low res photos with the files then send seperate high res files that would be swopped in before printing.
    I mean it does show up on the monitor and print but is it worth it in ink and memory? Or as I think, it is very subjective, once you pass a minimum resolution, which many people don't, I mean like 32k at 300 x 600.

    Hard question to answer as it quite depends on what you want to do with the actual photos.
    Then you have to disentangle the file size (the 32k part) from the dimensions (the pixels part)
    Dimensions:
    2,000 x 3,000  isn’t very high resolution these days. That's 6 megapixels and phones come with that regularly now. Point and Shoots turn out at 14 megapixels, DSLRs start there and go up.
    Pixels are about acerage. If you print the shots, then the more pixels you have the better the quality of the output at larger sizes. If we use the 300 dpi 'rule-of-thumb' as a good quality setting for printing, your 2k x 3k shot will give a maximum print size of about 8" x 10" Ever print larger? If not, then you probably don't need more pixels.
    If you never print at all, then, what’s the largest screen you view on? Any pixels more than that are wasted.
    File Size:
    Given the numbers you mention (1 MB 64k, 32k) I'm guessing you're referring to Jpegs.
    I'm not sure where you're getting these shots at 64k etc, but they sound very very like material from Webpages and the like. These are very, very heavily compressed to make download times short. Every time  jpeg is compressed it looses data and a: these images will print very very small (using the same measure above 300 x 600 will give you  1" x 2" print) but more importantly, as they contain so little data they will print very poorly, bad colour matching, jpeg artifacts, dull, lifeless.
    On screen this is less of an issue but there is still a big difference between the data available in a shot with 1mb of data behind it and one with 32k of data behind viewed at the same size. And that is perfectly preceptible on an good quality screen. So, while the shot at 1mb may get the grain on the floorboard in your example, that grain will be blurred, the colour patchy, at 64k.
    Another issue to bear in mind is future proofing:
    We have no idea what our photos will be viewed on in 20, 50 or 100 years time. Or even now, when folks are viewing photos on enormous HDTV screens via various devices. It's does seem obvious that the more data you preserve then the more there will be for future users to work with.
    Other considerations:
    The value you place on the photos. If you're someone who snaps friends doing silly things at parties and uploads them to facebook, you might not place the same value as a serious hobbyist archiving their family history.
    What camera do you use? For me, the most important element in the quality of a shot is the lens on the camera. If you're going to use a $2000 lens and compress the image to 64k then send me the lens and use your phone for snaps
    Cost: How much are you prepared to spend on storage. Hard Disks are cheap but managing 40k, 50k, 100k photos takes time and thought.
    In the end, when you go through all of these you can only answer for yourself. My answer is that I shoot with a DSLR in Raw, output to Jpeg when needed and preserve the original files at all costs. The jpeg I output depends on the use I have for it - and I can export at different filesizes for different uses: X to email, Y to upload to a website, Z for printing at whatever size. My wife shoots  with a Point and Shoot at 14 mp, we preserve the original in exactly the same way and ditto with the output.
    The principle reason for this? Future proofing is important to us. We we're working on the basis that the more data we have preserved the better chance that it survives in a usable form for the next generations - of device and people.

  • How do I resize/change resolution of photos from iPhoto when used in iWeb

    I am shooting with a 7.1 Mega Pixel Canon to get enough quality to crop and print high quality pictures of my baby daughter and her adventures in the world.
    I have a website up made with iWeb, but when I select the photos in iPhoto and go Share / Sent to iWeb / photo page - I get a nice layout of the photos but at full resolution when the thumbnails are selected or the slide show is run. Although nice and sharp, this is a pain for anyone looking at the site even with high speed access.
    There must be some way to resize photos, but I have yet to figure that out with iPhoto, let alone iWeb. And as one photo at a time is a pain, there must also be a way to rescale a whole selection of photos that I want to use for a page - say her Disneyworld trip. I can't be the first person to run into this, but I have not found anything out there to point me in the right direction.
    Ideally I wold like to create a resized set from the originals - so I can still print and crop in high qulity. I also am not really sure what resolution would be best or easy viewing and download - that's probably subjective. 1200x800 comes to mind but I am open to suggestions.
    Perhaps resize is not the right term - changing resolution is probably more accurate, but there too I have not found an answer.
    Appreciate the help and suggestions.

    dan28088,
    Tried your site on two different browsers, using highspeed broadband; the site is, indeed, extaordinarily slow. We can dissect the thing down to the last file, but it won't change anything, as far as I can see. If it were me, I would host the site on another server. The .Mac servers are just plain slow, period. I think that is the primary problem here. Just my opinion, others may disagree.
    I created a new site this past weekend for a new project, and published it to .Mac. It contains a lot of jpeg files in slideshows (along with the usual png suspects!) . After reviewing it a few times, and not being satisfied with page-load speeds, I published to a folder and uploaded the site to space on 1&1 WebHosting.
    The page-load speeds TRIPLED. That's right...3X as fast page-load speeds. Even large, linked to files, 3MB+, load within a reasonable amount of time. (seconds)
    I still will keep a .Mac subscription, as I like and use all of the other features of the iDisk. But for serious website hosting, I think you will be better 'served' with a remote host. Your money with .Mac is certainly not wasted; the syncing services and other features of iDisk space that integrate with your local files are well worth the yearly fee. Again, only one user's opinion, based on experience.

  • Resolution of photos shared to  FB with IOS 6?

    Is there a way to specify the resolution of pictures uploaded directly to Facebook via the Share button in Photos on IOS 6?  I shared a photo to FB, and when I downloaded it from FB, it had a resolution of 960x717.
    When I shared the same picture via email to myself, I got a prompt when sending the mail, asking me what resolution I wanted.  I requested full-size, and the picture I received was 2592 x 1936.
    Does anybody know where the size is limited in the FB share?  Is the limit imposed by FB or IOS?  Is there a way to change it?

    Thanks Roaminggome ^^
    YES i ve checked for any restriction  and... No restriction on "camera" or if it s disable ... I ve no bloody idea WHERE it is and "WHEN" i did that
    Of course i ve searched on other pages and folders if the little icon have "jumped" somewhere else ... BUT no ...

    oldhoss:
    You mean you've not found out how to resize images with Photoshop? It's all in the Image->Image Size menu. Enter the pixel dimensions in the boxes and go from there. Also PS has the capability of saving for web. I can reduce a 1600 x 1200 jpg file from 1.7MB to 212 KB by selecting the Medium quality level (5) in the Save As window. However, using PS's "Save for Web and Devices" menu option, medium jpg option, it is only 112 KB and the image quality is outstanding.
    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 written 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. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

  • What resolution are photos optimized for ipod display? (post computer sync)

    From what I've read here, iPod touch forces photos sync'ed from a computer through a optimization step for display on the iPod (and TV). Full-resolution images can only be stored on iPods that have "enable disc use" mode (which iPod touch does not have), and even that mode on older iPods could not be viewed/displayed on the iPod itself.
    Just curious...
    1) what resolution finally ends up on the iPod side (not sure if it is the same as older iPods)
    2) if the zooming feature on the touch goes beyond the optimized photo resolution to the point of interpolation to fill in the blanks
    Thank you ahead of time for your insight.

    Anyone know?

  • Changing resolution of photos

    Hi I am a new user and hope someone can help with some information
    I would like to change the resolution of some digital photos to (640x480) by "downsampling" in IPhoto before importing to I Movie.
    Does anyone know how to do this and will this reduce the file size?
    Thanks in advance!
    GRF1

    GRF1,
    There is some great information in this page by Matti Haveri, one of the iMovie gurus: http://www.sjoki.uta.fi/~shmhav/SVCDon_aMacintosh.html#slideshow
    In this section about slideshows he discusses the math involved in figuring the pixel dimensions of still images to be used in your movie. Notice he says that if you downsize to 640 X 480 that your images may appear somewhat fuzzy, and that there is really no room to zoom in with the Ken Burns effect. If you do plan on zooming in, then you need to calculate for the zoom. For example, if you zoom in at 2X the picture size, then you need double the pixels in order for the image to look good during the close-up.
    Also notice his recommendation of a 3rd party application PhotoToMovie. He says it reduces flicker by slightly blurring the images. Many iMovie gurus have compared its slideshow capabilities to that of iMovie and iDVD, and have reluctantly come to the conclusion that it is better. Since your slideshow has so much architecture, it might be worth looking into. You can create the slideshow in PhotoToMovie and then place in into iMovie so that you can burn in iDVD.
    Another great source of info is Dan Slagle's Unofficial iMovie FAQ. He quotes another guru, Fred Shippey, who gives the pixel math involved in stills which will be zoomed. You can follow his link to Fred's quality test. Notice again the recommendation for PhotoToMovie, which Dan and Fred agree does a better job of rendering the slideshow.
    For more information about flicker and jaggies, read Karl Petersen's test here: http://discussions.apple.com/thread.jspa?messageID=2909799&#2909799 and here: http://discussions.apple.com/thread.jspa?messageID=2105598.
    Lots of homework, but I hope it helps.

  • Full resolution iPod photo option not available??

    I want to transfer my photos to my iMac using the Full-resolution photo option so I can then transfer them back to other computers. The problem is the full resolution option in the iPod options is greyed out. I have enabled disk access as per the iPod tutorial. What else do I need to do?

    Unless I misunderstand your question....
    The two places (ipod and mac) where you could view your library images are displayng two different sets of data.
    The iPhoto library was in one format and the iPod has only (ipod formated) thumbnails on it.
    The iPod thumbnails are kept seperate from your iPhoto Library. On my machine they are in my PICTURES folder in iPod Photo cache.
    Since this is not the same set of files you could not restore it.
    NOW IF YOU REALLY HAVE YOUR iPHOTO LIBRARY on your iPod you could move it back to your hard drive while in disk mode to the expected location but DO YOU REALLY HAVE THAT FOLDER or do you have the thumbnails of that folder?

  • Preview - low resolution on photos

    If I create a pdf document containing photos and open the same document in both Preview and Adobe Acrobat, the Acrobat always has sharper images. It seems like Preview works at a lower resolution. I have spent much time testing all different types of pdf files, saved at different resolutions. No matter what I do, the photos when viewed in Preview are less sharp than Acrobat.
    Has anyone else experienced this and is there a way to change Preview?

    Im makeing a photobook and the photos Im importing need a higher resolution, Can I do that in Iphoto?

    No - it is impossible to "improve" quality once you have a photo - you can change teh numbers but anything you do will at beat leave the quality unchanged and generally will reduce it
