Does auto-enhance resize photos?

I was editing and emailing photos to myself through the photos app and noticed that the max photo size changed. I clicked "edit" then "Auto-enhance" and then "Save". When emailing the photos the "actual size" option is now smaller (800k vs 2 MB) and the resolution is lower. I had not heard about this before and was not aware auto-enhance resized the photos.

Any time you encode, or edit, a jpeg file, which is a type of picture file, it reduces the quality of the picture and to make up for the loss the resolution is lowered

Why does Auto-enhance reduce resolution?

I noticed when I apply auto-enhance to pictures taken on my iPhone 4S, the resolution in the EXIF data shows just over 3MP. I did a before and after and saw a huge drop in resolution. 3264x2448 without auto-enhance and 1536x2048 with auto-enhance used. No cropping was done. The only edit applied was auto-enhance. Why does the resolution get reduced fom 10mp to just over 3mp?

Scanned images, borders, cropping and "auto enhance"

Afternoon.
I'm converting old slides / negatives to digital, and am aiming to store the results in aperture.
I'm still fighting through the manuals etc. and trying to work out a workflow that works for me between Silverfast and Aperture. One of the decisions to make is where / how to do the first pass "auto improve" steps. I'm keeping the "raw" scan (HDRi, 64bTIFF etc.) to reprocess the ones I'm really interested in later, but I'd like as automatic / quick a process as possible to actually get the images into Aperture, and looking OK, first.
Many of the images have some black or white borders from the edge of the slide holder / curved corner of the slide being included in the original scan (the "autocropping" in Silverfast is kind of rubbish).
How does "auto enhance" work with regard to this non-photo information? Do I need to crop before hitting "auto enhance" (so it's not factoring in the edges?)? Can it be automatically "refreshed" after cropping? Any other advice?
I know some of the manuals on silverfast mention needing to crop this stuff out before using their "auto enhance" like features, but it's another time consuming process, and something I'd rather be able to undo (i.e. uncrop if I decide later I want the original curved corners / edge detail back).
Hope that made some sense.
Thanks.

I'll correct my answer. It's simpler than I thought and works well.
In Acrobat X I can use Tools/Recognize Text/ Aa In This File which will deskew and process page(s) for OCR, i.e. make it a searchable document. When I do this on a multiple manually scanned document which has pages upside down,
the deskew rotates them 180 degrees, that is corrects the manual scan orientation.
This worked with pages of both landscape and portrait, but haven't tried with 'sideways' manual scan.
All the incorrect pages were upside down. There's also a selection to do this with Aa Multiple files, which I haven't tried.
The deskewing in the others I've tried with this menu choice have all been accurately straightened and the text of all kinds remarkably is not only searchable but can be copied and pasted into other documents/applications with Control C and Control V.

When I "enhance" a photo, it does not show up in slideshow, it is just black

When I "enhance" a photo, it does not show up in slideshow, it is just black. I am using Iphoto. I also can't email these "enhanced" photos.

There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?

Can't transfer any photo edited with Auto Enhance.

Ok...I have a TOTAL love/hate relationship with my iphone 4s. I love the Auto Enhance feature, but once I have enhanced a photo, I am unable to transfer the EDITIED photo to the cloud or to my PC! Why Not? This totally seems to be against the Apple advertising which states "you can edit something here, and it appears There" and so on and so forth. That's just not happening. Apple has tricked us, I'm afraid!!! I spend a bunch of time cropping and editing photos and then the only place I can view them is in my iPhone? I'm so frustrated! I've been looking for weeks on end online for a solution, even local iphone experts don't have an answer! come on !!! HELP! I'm using a Windows PC with Vista. If you can give me the right answer, you will be the smartest person I know! Unbelievable!!!

For your laptop, a lot of computers don’t provide enough power to their USB ports to charge the iPad at a sufficient rate - it may still be charging slowly, and should be a bit quicker if the iPad's screen is off (if you leave it for a while and then disconnect it from your computer you may find that it's battery percentage has gone up). The wall charger is usually the most efficient way to charge the iPad.
If your iPad's wall charger is also not charging it then have you tried a soft-reset to see if it charges after the iPad has restarted ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
If not then have you tried a different charger and/or cable ? Do you know anybody else with an iPad so that you can try their charger and cable and they can try yours ?

I accidentally touched the auto enhance icon in iPhoto and now the program is stuck at "Updating photo." How do I make it stop?

I accidentally touched the auto enhance icon in iPhoto and now the program is stuck at "Updating photo." How do I make it stop?

Try to quit iPhoto from the Home Screen - the recent app section.:
Double click the Home button to reveal the recently used apps.
Then tap and hold on the iphoto for ios icon until it wiggles. It will show a "minus" sign in the corner.
Now tap the minus sign to quit the app.
Click the screen above the row of recent apps to return it to normal.
Now restart iPhoto and see if it back to normal.

IPhoto had a auto import folder. does this exist in photos for mac?

I used image capture to get the photos from my iPhone, so that iPhoto didn't open every time i plugged in. there was an auto import folder in iPhoto which i could dump my photos in, then when i did open iPhoto it would import everything in that folder. is there a folder that will import everything in that folder whenever Photos for Mac is opened?

What does iPhoto do with photos as they are imported?
What you tried was a very complicated and unsupported way to import from one iPhoto library to another.
The safest way would have been either
to use iPhoto Library Manager to export a new library from the old one
or to export the original files using iPhoto and to import the exported files.
But pasting the Masters folder into a temporary "Importing" folder put your photos at risk. The Importing folder is a temporary cache that will be emptied, when an Import has finished.
It started to get very slow and sluggish, so I decided I would move the photos to a new library on the same drive.
It would have probably sufficed to repair or to rebuild the library and safe all your edits and albums, instead of migrating the photos to a new library.
Since you do not have a backup, and your Masters folder got erased, I recommend to stop using the drive with your library immediately and to try data recovery software, for example Disk Drill. It has a free trial mode.

Aperture 3.3 auto enhance not working properly

I am having issues with auto enhance, having decided to go back and reprocess some older RAW files. It changes the picture which is currently being displayed, however although I can see it regenerating the thumbnail, the thumbnail stays the same as before. Then if I move through a few more pictures auto enhancing them, and return to the first one, the picture is back how it was before auto enhancing it (although all the effects settings say otherwise). If I auto enhance it again, I can see there are no changes to the effects settings, yet it replaces the picture with an auto-enhanced version again. But it never sticks. To summarise in case I am not being clear:
Suppose I have pictures A, B and C:
Auto enhance A - appears to work, picture changes, effects settings change, thumbnail is regenerated incorrectly (still looks like before auto enhance)
Auto enhance B - appears to work, picture changes, effects settings change, thumbnail is regenerated incorrectly (still looks like before auto enhance)
Auto enhance C - appears to work, picture changes, effects settings change, thumbnail is regenerated incorrectly (still looks like before auto enhance)
Return to picture A - picture shown is prior to auto enhance, yet effects settings are from after auto enhance
Return to picture B - picture shown is prior to auto enhance, yet effects settings are from after auto enhance
etcetera
Things I have tried:
Revert to original, and reprocess
Regenerate previews
Regenerate thumbnails
Repair database
Rebuild database
Remove plist file
Nothing has made any difference.
If I use some other auto setting, e.g. auto curves, then everything works exactly as it should. Therefore, it does appear to be some sort of bug with auto enhance. I was wondering if anyone else has seen this. And I thought I would mention it just in case anyone is reprocessing a series of pictures and hasn't noticed that although the effects setting changes are sticking, the actual previews and thumbnails are not updating correctly.

I've just noticed that this behaviour is not consistent. It seems to be that some projects work but others do not, even when the RAW masters were from the same camera. i.e. either all photos in a project work, or none work.

How do i resize photo attachment in icloud mail

How do I resize photo attachment in icloud mail. The resize button does not appear as it did before.

Using iCloud mail online via a browser does not offer the option to resize the photo. It's only available when emailing from iPhoto so iPhoto can do the resizing as it adds the image to the email. Safari or whatever browser you're using doesn't have that capability.

How to save resized photo in the event

I am having trouble saving my resized photo in my event. When I open an event, choose the photo I want to resize, and use the export feature, I am unable to choose my event as a place to save to. Any suggestions. What I end up doing is saving it somewhere else I don't want to based on my limited choices in the drop down and moving it to the event. This is a hassle.
I also tried to resize the photo using the preview program and saving it to my event. THis way I at least got the option, but the saved file doesn't show up in the iphoto event, only in the finder when I view all of my photos.
Any suggestions. In a perfect world I just want to upload photos from my camera, iphoto creates an event which is great. and now I just want to resize them and have the original and the resized photo in the same event visible in iphoto. Is this possible?

Welcome to the Apple user discussion forums
If you want to have two different resolutions of a photo in iPhoto (and I can think of no reason to have this) you have to export the photo in the second resolution and import that new photo into iPhoto
You should never "save" anything into the iPhoto library - iPhoto is a database and you should never add or modify anything inside the iPhoto library

How does iPhoto organises the photos?

Dear fellow Mac users,
how are you! Tonight, my parents had a lot of fun taking photos of them using Photo Booth... awww. those love birds haha.. and i made a music slideshows for them. (too bad i dont know how to burn it into a VCD for them to watch on TV). I dont have a DVD RW.
My question is
1. How does Iphoto organises the photos? It seems like there are many dublicate copy of the same photo.... i am kind of confused. (There is .. Original Folder and Modified Folder) and worried that it will eat up my disk space
2. Is it possible for me to burn a slide show VCD?
Thank you soooo much!

StanB:
As PhillyPhan warned, you don't need to use the Finder to locate an image file for use outside iPhoto. You can either drag the thumbnail to the desktop to get a copy of it or use the File->Export->File Export menu route to export the file to the desktop. The second option allows you to resize it if desired. So there's no need to go rummaging around in the iPhoto Library folder to find a file.
Do you Twango?

Resizing photos in iPhoto 6

Hello,
I've been doing this in Photoshop for a long while now, but am curious as to how to resize photos using iPhoto 6. I don't seen an obvious way to do this, but I'm probably just missing it. What I want to do is take an image at 2816x2112 and resize it to 800x600, without cropping. How do you do this in iPhoto 6?

found the answer by doing a little more searching in the forums!

Batch Resize photos Larger than a certain size.

Is there a way to have a script that searches a directory and any image files that are larger than 1000 x 1000 pixels are resized to 500 x 500 pixels and then saved over righting the sources file?
I am asking because our server has over 40,000 photos all over the place and I would like to reduce the space they take on the server.

I don't think that getting the file's length is the best way to determine if the file needs resizing. Especially if the file is in a format that supports compression. I think you would end up either setting the test value too low and open a lot of files that don't need resizing or set too high and miss files that do.
Also using getFiles() without a file mask will get all files and folders in the source folder. You will need to make sure it is an image file before trying to open in Photoshop to resize.
I think the function below would be a better way to determine if the file needs resizing. It tries to get the XMPMetadata to determine width and height. If that fails because the file does not have metadata it gets the size from Bridge.
var file = new File('~/desktop/_SLP7637.jpg');
var resize = needsResizing( file );
var resizeStr = ''
resize? resizeStr = 'needs resizing': resizeStr = 'does not need resizing';
alert(file.fsName+" "+resizeStr);
function needsResizing( file ){
    try{
        loadXMPLibrary();
        var xmpf = new XMPFile( file.fsName, XMPConst.UNKNOWN,
                                   XMPConst.OPEN_FOR_READ );
        var xmp = xmpf.getXMP();
        xmpf.closeFile();
        var dim = xmp.getProperty( XMPConst.NS_EXIF, 'PixelXDimension', XMPConst.STRING)+','+xmp.getProperty( XMPConst.NS_EXIF, 'PixelYDimension', XMPConst.STRING);
        dim = dim.split(',');
        unloadXMPLibrary();
        if(dim=="undefined,undefined"){
            var dim = undefined;

            bt.target = "bridge";

            bt.body = myScript;

Auto exposure not applying when using the auto enhance function

I am on Aperture 3.6 and Yosemite. I use a Canon 6D and shoot in RAW. When I am doing the batch auto enhance to my shots, I find that even though in the adjustments preset Auto Enhance includes auto exposure, often it is actually not applied. Are there anyways to fix this? The images actually are a bit underexposed and I now need to go through picture by picture to click on the auto button under adjustment. Thanks.

Have you set your camera to use Canon's Highlight Tone Priority? Then most of the Raw files will be underexposed, because Aperture is developing the RAW file "as is" and not applying the in-camera settings. See Keith Barkley's user tip.

How do I resize photos to fit within Source or Program?

I was able to do so in Source or Program before but no longer able to. Using PP5.5. Just setup my editing system, using exact same equipment, after not in use for four months. I had edited other projects where I had to resize photos and was always able to resize within the Source or Program monitor.

Right-click any clip on the timeline and choose "Scale to Fit". Or set that up in Preferences (does not affect media already imported) so it is automatic. Can still be manually over-ridden on timeline on a per-clip basis. Easier than scaling a lot of stills one by one.
Thanks
