IPhoto switches resolution for slideshow

I'm using a Viewsonic widescreen monitor with my Mini G4 which works just fine at a resolution of 1600x1050. When I start a slideshow from iPhoto, however, the display switches to 1280x960, and the photos appear stretched horizontally.
I've read elsewhere about issues with certain monitors and the 'coherent' display problem, but I can't see why this problem should only manifest itself during iPhoto slideshows!
Any insight into this would be much appreciated.

Same problem here, but using a different external monitor. One post elsewhere recommended rebuilding the library, which I tried. Didn't help, but it took a long time. I'm using iphoto 6 on an ibook g4.
I'm about to switch to version 8 with a macbook. Can I hope the problem will be solved with that version?

HD resolution for slideshow?

Hi there,
I've been creating photo slideshows for some time and I knew this was going to happen sooner than later: a question about HD.
I've already explained to the client that the DPI doesn't matter for a TV, but he asks again:"
What DPI resolution do you suggest to best view them on my DVD player and T.V. (I plan to buy a high definition large screen set next year). I understand that there are 1000-2000-4000 etcetera. DPI resolutions; I want the images to be as close as possible to the original slides without going too crazy on this issue as they will be for viewing only (no prints or enlargements or archiving). "
I explained that the photos will look amazing, as close to the originals as possible, but do i need to consider anything for HD?
Cheers,
Keebler

Hi David,
In honour of that post and to reflect my lack of proper searching, I'll call myself a postidiot
I should've seen this, but thanks very much for the link.
Onward I read!

I am using Lightroom on my MAC where I import the finalized JPEG-pictures into iPhoto to create a slideshow (for instance in combination with films). When exporting the slideshow with a 1080p resolution to iTunes I experience difficulties (missing slides and black transitions). When using JPEG-pictures directly from the camera there are no problems, so the manipulation in Lightroom seem to cause corrupt files. Does anyone recognize tje problem and could it have anything to do with the introduction of the Yosemite software? Is Lightroom already Yosemite-proof?

In iPhoto 11 the Originals folder is renamed Masters.
IPhoto menu -> Provide iPhoto Feedback and report the bug.

Using Photoshop Elements to scan but iphoto for slideshow

I use an Epson V600 to scan old photos, which runs on a Photoshop Elements program. I am creating a slideshow for my grandmother's 90th birthday party, and I prefer to use iphoto for the slideshow. What is the best FORMAT for the photos as they are scanned, and how do I transfer to iphoto? Thanks for the help!

Welcome to the Apple Discussions. Scan the photos and save them in a folder. When you're finished scanning import that folder into iPhoto. This will give you just one Event with the photos in it. If you import each photo after it is scanned you'll end up with a separate event for each photo which can be a bit of a pain.

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.

Does iPhoto alter images when importing from camera ?(+ tip for slideshow)

I came across the following article:
http://www.andrewburke.orconhosting.net.nz/mac/builtin.htm#photo
The claim here is that during import iPhoto alters images in some way. The iPhoto experts, Terence OldToad, LarryHN and others, could you please comment, what's your opinions on this ?
Resize Images for iPhoto Slideshows
If you are running a slideshow in either Preview or iPhoto, you want the image being shown to be exactly sized to your screen. Images from almost all modern cameras are much larger in pixel dimensions than your Mac's display, so they will be interpolated down to fit. When they are resized on the fly through interpolation they never look as crisp or pristine.
When I import images from my Nikon to the Mac, I keep them outside of iPhoto and at their original size, as an archive from which I might eventually produce some prints. From there I choose the best examples that I want to display onscreen and copy those out of the archive for processing. Each one of those favorites that I've chosen is then tweaked in an image editor (I use Gimp Shop) and the final step before sharpening is to resize it down to match the dimensions of my display.
My iMac is 1440 by 900, so if an image is narrower than that ratio I scale it so the height is exactly 900; if it's wider I scale it so the width is exactly 1440. After these tweaked and resized images are finished I import only those into iPhoto. Then when I run a slideshow they are displayed exactly at their original size (not stretched or shrunk to fit the screen) and the difference is stunning.

What he says is +"you want the image being shown to be exactly sized to your screen. Images from almost all modern cameras are much larger in pixel dimensions than your Mac's display, so they will be interpolated down to fit. When they are resized on the fly through interpolation they never look as crisp or pristine."+
The title of the piece is +"Resize Images for iPhoto Slideshows".+ He is talking about you resizing photos before you import so they will match the screen size during the display of a slide show on the screen - not iPhoto changing anything during the import of the photo but during the display of it - This is a bit like the cropping during printing questions - if you want to control exactly have is being shown (or printed) rather than use a generalized scheme to make photos fit a non native size then you much do the changes yourself
I'm sure that he is correct but since I use iPhoto as a photo library manager which lets me show quick and easy slideshows, I have no problem - *my original, unaltered photos are there in iPhoto* and available for use as I see fit - the degree of modification that takes place in the display of a slideshow has never even been noticeable to me - but then I do not see iPhoto as a single purpose slide show viewer - in fact that is a very minor feature for me

Screen resolution for iPhoto

Screen resolution for iPhoto-I keep getting the message when I open iPhoto,"screen resolution not optimal for iPhoto". How do I find what is the optimal resolution?

Iphoto: resolution for 4x6

I am trying to upload photos to Walmart to make an online calendar. When I select the photos in Walmart's calendar program, I get the message "not a recommended resolution for printing". I've never had this issue in the past several years, but new camera, and new mac, so I'm not sure where the problem lies. Can you tell me what resolution is recommended for 4x6 prints, and what I have to do in iphoto to change to that?

Pretty much depends on what Walmart consider a good resolution. But a rule of thumb: 300 dpi is often considered good. For that you will need a snap of 1200 x 1800 pixels. (Think: 4*300 x 6*300) What size images do you have?

Updated iPhoto could no longer use the music from iTunes library for slideshow

Anybody checked if you can still use your music from iTunes library for slideshows?
After updating both iPhoto and iTunes to the latest version in Mavericks, all music links in the iPhoto's slideshows became invalid. Tried even to re-establish the music links, but it seems like the iPhoto would not play any music from the iTunes library. Only the sample music from iPhoto is usable. The iTunes works fine by the way.
Thanks a lot!

I think I found a workaround that seemed to correct the problem. In iTunes, go to the File menu and choose Library. Then select Organize Library. Next choose Reorganize files in the folder "iTunes Media". Click OK.

IPhoto 9.1.1: slideshow images are zoomed into blurriness

New Mini 2.4, new Acer HD widescreen display, iPhoto 9.1.1 bundled. The mandatory library "update" on startup corrupted my library. Found a fix here to trash the iPhoto plist and reload the app. My old slideshows are gone, and when I select a range of photos and click "slideshow", I get the whole range in mini-thumbnails along the bottom; that's nice, but...when I play the slideshow, the images are so zoomed out that every last one is blurry. It looks like a nice photo in Preview after you hit "zoom in" about 5 times; it starts to pixelate, but this is just plain blurry. I posted another topic today about display size, and I wonder if these two flaws are related. The display puts a ridiculously small snapshot on the display, and full-screen simply puts the same dinky image on a field of black.
The subject images are, admittedly, mostly 1.3mp and 3.5mp. A few I took with my new 18mp Canon behave pretty much like they all used to. I've tried changing the monitor resolution from 1080p down to 720p, but it doesn't make much difference. The older ones looked fine and were zoomable without pixelating on my old Acer 1914 LCD monitor, so I didn't expect such a radical degradation of quality simply by upgrading to an HD monitor. The older photos (99%) of my library, are pretty much useless for slideshows now.

Create a new test library, import some photos and see if the problem persists. If not then your original library is damaged. Backup the library and try the three fixes below in order as needed:
Fix #1
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/Library/Preferences folder.
2 - delete iPhoto's cache files that are located in your Home/Library/Caches/com.apple.iPhoto folder.
3 - reboot, launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding the the Option key. You'll also have to reset the iPhoto's various preferences.
Fix #2
Launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library. Select options #1, #2 and #6.
Click to view full size
Fix #3
Rebuild the library using iPhoto Library Manager as follows:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 -Download iPhoto Library Manager and launch.
2 -Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File->Rebuild Library menu option
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

I Need the correct resolution for images imported to iDVD

Maybe some kind soul can help me out. I took some photos with my digital camera. Made slides of them in Powerpoint, imorted to iPhoto then to iDVD slideshow and all was fine. No cutoffs of top or bottom and no black bars. Now I've tried for another project to take these sides from Powerpoint, import to iPhoto, set up a slide show with timings and sound. then export to iDVD, but it cuts the tops and bottoms of the pictures. I've read everthing I can find on proper resolution and ratio. I constrained them to the 4:3 inside iPhoto and still cutoffs of top and bottom. I put them into Photoshop and constrained to 640x480 as suggested and then after import to iDVD there are black bars on top and sides when it plays on a tv/dvd player but looks okay on the computer moniter. I need the slides to be full on the tv safe area and show full on a tv with no black bars or cutoffs. I've gone nuts trying to figure this out. Any help would be GREATLY appreciated. Thanks in advance.
Steve

Steve,
This sounds to be the REVERSE of a TV Safe Area problem. The usual problem is the images show correctly on the computer monitor but are missing edge information when played to a TV set.
640x480 works with the iApps through iLife '04. The iLife '05 apps expect NTSC images to be 720x534 pixels - using a 640x480 image will result in black bands on either side of the image. PAL is 768x576. Note that these are listed as standard size images when creating a new image in Photoshop.
The only way to get a slideshow to show everything on both a computer monitor and a TV set is to include the slideshow twice - once with no edge masking for computer use and once with the edges padded with black so everything will be shown on a TV set.
Edit: I just reread your original post and you may be seeing effects caused by the Ken Burns effect not being turned off.

Camera resolution for NetStream. Please help.

I'm developing a videochat app that should work on different network speeds. The idea was to switch to lower resolution if by some criteria delay becomes too noticable (say, delay is 2 seconds, or dropped videoMessage packet ratio is more than 20%). Or if on the other hand user has fast network connection then app should increase the resolution and thus providing better video image quality.
The problem: I can not find anyone done this before, thus I am comming to the conclusions that I'm doing something wrong here.
Is it possible that RTMFP is lowering the video image quality automatically when ever it thinks that delay is too huge? If this is the case, than should I set the video resolution for camera to 1600x1200 and feed it to the netstream and allow NetStream to take care of everything else, or there is some other magic numbers for resolution that I should set?
If this is not the case and RTMFP is not taking care of lowering/increasing video quality automatically then how can I measure the quality. I know there are NetStream.info and NetStream.liveDelay, nether of which for RTMFP connections provides valuable information to detect delay. For me liveDelay is going up to 20 and then fluctuacting there, but for info videoLossRate property is always zero, even if I set everything to max and lag is very noticable.
So how is RTMFP intended to use?

I agree. In fact, make it your workflow when sending this type of file to an online vendor. The importance of the 350ppi requirement is for any of your transparency or raster effects to match their RIP's output line screen. It's becoming an industry wide mistake to refer to file resolution in terms of dpi. Do yourself a favor and get familiarized with the terms dpi and ppi, what they really are and what importance they play in output. The advantage to PDF is the fact that you can establish the output resolution, color settings, and font embedding that will trim the variables that could go wrong on the vendor's end. Your job is to make sure you apply the correct resolution, color, and font settings in the original file and again when you generate the final PDF. If you are unsure, find a local print provider that knows what they are doing and can teach you how to setup a file properly. You may have to intern somewhere, take a good course somewhere, and/or buy a really good and accurate book on prepress file standards. Try your local book store or library. Use better keywords when searching on the web, take a look at some of adobe.com's resources ( i.e., A Designer's Guide to PDF or similar ). Now, you will need to learn more about Illustrator Color Settings and the Raster Effects Resolution Settings. These are two areas you should spend a little time getting to know how different settings will affect output. In the case of your business card, set the raster resolution to "High". That will cover you on their 350ppi requirement. Do not get discouraged by seeing their proof on screen. It's just a preview. Do not get too comfortable with what you see on your screen unless your entire workstation is calibrated and even then you have to be cautious.
