Aperture Photo JPEG Export Size

I have a question regarding the file sizes of photos exported from Aperture. When exported the photos seem to be almost double the file size of the original photo imported to aperture and the size shown in Aperture. For example, I have a photo that is 2736x3648 sized at 3.51MB in Aperture. I export with JPEG set to original size, JPEG quality is set to 12. The resulting file size exported is 7.1MB. The resolution of the exported photo is also 2736x3648 so I don't think it's a DPI issue. I've done some experimentation with the JPEG quality and the results are still strange. 10 gives me a 2.2MB file, 11 gives me a 2.6MB file and 12 as mentioned previously is 7.1MB. Seems like a huge jump so I suspect I'm missing something. The other sizes being smaller than the original also seems strange.
I've looked at the exported photos at 10,11&12 and can clearly see the detail lost. The darker parts get darker and drop the detail in the photo. I'm very reluctant to lose quality so ideally would go with 12.
I know there are a few questions like this on here already but none of them seem to have a good answer. Just wondering if anyone has figured it out?
Thanks in advance.

Terence, you've helped me on a lot of things, so I guess I am going to further ask for clarification....
I have recently been trying to use Aperture solely (and pretty much abandon iPhoto.). But, when I say export a file to jpeg (whether it is currently a RAW or JPEG file, I am concerned about my settings-- by default, the setting "export jpeg in original size" has settings as 72 dpi. I have changed that to 300dpi. Is this why I have 15-20MB files? Is this the correct setting? I don't want any printer to have a false representation of how much data is there. Nor do I want to lose any data either.
I could theoretically take any photo and probably even say 4500dpi, and the file would be exaggerated that much more. I go to print, and the print center sees there is plenty of resolution there, but in reality, there is no more data there than the extent to which the file provided. You can't create resolution that is going to improve on what your camera or the minor adjustments you do to it to improve it. I say export it at whatever maximum dpi it has or multiply that dpi by 100, and no matter what, the image is going to print the same no matter how much data (or how large the box is).
Also, if I open my library in iPhoto and tell it to export the photo at original size, the file is smaller than the file exported via Aperture (thus my concern I am providing more detail than what is really there) and providing an exagerrated resolution. Your help is greatly appreciated. I am providing a disk to someone, and this is affecting whether I give them one or two disks due to the file sizes. (And, of course, as is, the file sizes are harder to work with if you want to email. So, if they don't have an email program that auto-condenses, they may be frustrated not having smaller files if they choose to email any.)
Thanks in advance!

Jpeg export size and quality issues

aloha,
I use a lot of photos in articles on the web and size them to about 250 x 166 pixels. I just tested Aperture, Photoshop CS2, Fireworks 8, and Graphic Converter at levels of low, med, high or 30, 60, 80 or 4, 6, 9.
The best quality in terms of sharpness, clarity and color was PS CS2, with Aperture second. But Photoshop's files were 12, 24 and 36 k respectively, where the Aperture files were 72, 74 and 88k. In fact even at quality 0, the Aperture-generated jpeg was 64k. Fireworks were 4, 8 and 16k but surprisingly poor quality. Graphic converter was 116, 120, and 124k, with decent quality.
It appears that Adobe's engine is more adept at re-sizing and compressing (not entirely surprising). It leaves me with a bit of a workflow issue, since opening the files from Aperture into CS2 leaves me with a gigantic .tiff in Aperture I don't need.
Full size jpegs could be exported from Aperture to a folder, then opened in Photoshop, resized, and saved for the web. I can automate the Photoshop part of it, but would need some help automating the whole process.
Any information and suggestions folks have would be appreciated! I am curious as to why there is a floor on the Aperture jpeg sizes. Maybe I need to turn some option off? I'd love to keep my workflow within a single program.....
mahalo,
paul

What we need are the clip properties & sequence settings in Final Cut Express. Your screenshot is from a Finder window.
It would appear you have a clip with nonstandard frame size (1366x768) in an H.264 file. FCE cannot edit this material. FCE is limited to specific codecs and frame sizes. You need to convert your clip to QuickTime/Apple Intermediate Codec. If it's highdef widescreen then convert it to QT/AIC 1920x1080i. Try using MPEG Streamclip to convert the source clip.
You also need to be using a matching Easy Setup in Final Cut Express. If your source media file is QT/AIC 1920x1080i then you should select the AVCHD Apple Intermediate Codec 1920x1080i60 Easy Setup in FCE -AND- then create a new sequence before importing your clip into FCE and placing it in your sequence (timeline)

JPEG file size

I have been using both Lightroom and Aperture, and have noticed that Aperture's JPEG exports are much larger files than those produced by Lightroom. I have been using what are seemingly equivalent JPEG quality settings (say, Aperture's #8 out of 12, and Lightroom's #60 out of 100).
Why is this so?
Thanks.

You would have to run a test with
i identical
images because a Jpeg's file size will vary considerably dependent upon the subject matter.
If there is a significant difference between two identical files, both saved at maximum quality, it will be because one program is saving more metadata than the other.

Quicktime Photo JPEG on Premiere Pro CS5

My current version of Premiere Pro CS 5.03 does not have the Quicktime Photo JPEG export option. It should. Must this be downloaded from somewhere? Thanks for the help.

Aperture won't export full-size jpegs

I'm trying to export full-size jpegs, but Aperture is sending out 24 KB images. I'm selecting the edited versions I want, then going File>Export>Version. I have the dialog set to JPEG - Original Size. Still, what comes out is a thumbnail.
Aperture 3.4.5
OSX 10.8.5
MacBook Pro
2.4 GHz Intel Core 2 Duo
4 GB Memory

Check, if your export preset "JPEG - Original size" is still set correctly.
In the "Export" panel set the "Export Preset" pop-up to "Edit".
In the "Edit" panel make sure, that "Size to" is set to "Original Size", and the quality to a high value, at least 10.

Export size from aperture to photostream

Is there any way of configuring what size of image is uploaded to the photostream?
As a DSLR user using large RAW files in aperture, when I tested the photostream option it doesn't give you an export size, it seems to copy the full size image over which took an absolute age for 4 images.
If it's going to take that long, it kind of defeats the object of having it in the first place, as I wanted just small versions to be able to view and show people on my iPad.
Any help would be appreciated.

As I have read from MacCreate.com and as I have tried and tested, Photo Stream on Aperture 3 uploads the native files to iCloud. So if you import RAW only files, it uploads RAW and pushes it to your devices. I imported some RAW photos on my iMac yesterday, when I open up my MacBook this morning it downloaded the same RAW files.
MacCreate suggested though if you import RAW + JPEG into Aperture, it will only upload the JPEG version.

I am having problems exporting my time lapses from quick time pro i need to save my files as photo jpegs but the standard video compression window will not open fully,

i am having problems exporting my time lapses from quick time pro i need to save my files as photo jpegs but the standard video compression window will not open fully, it just keeps my mac (old 1.6Ghz 2.5 GB sdram G5 still good for most stuff i need) spinning for ever but i can see compression type H.264 selected and the other setting but i can not select any other options as it still thinking but never opens! why is this happening how do i get round it?
my work flow is: 300 images shot on a 5d mark II medium jpegs opened in Light Room cropped to 16:9 then exported and opened in quick time i can save a .mov H264 giving me files sizes of 14 mb for a 16 second time lapse, mp4 9 mb. the only way i can get large files is saving as a self contained movie then i get 300mb files.
i need to save my files 1920 x 1080 photo jpeg codec as i want HD quality.
i am sure there is a simple way round this?
thanks guys!

It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.
How large is your hard drive and how much hard drive space do you have left?

Why would I want to change JPEG quality of photos when exporting them from iPhoto?

Why would I want to change JPEG quality of photos when exporting them from iPhoto? Changing the quality of the print changes the size of the saved file and thus impacts the speed at which it is moved on the internet. But other than size of the file, what is the advantage of changing the quality?

I have no idea why you would want to do anything
Some people want lower quality to reduce file size for different reasons
It is an option - if you do pot want to do that do not use that option

Can a photo be exported from aperture in CMYK profile

Can a photo be exported from aperture in CMYK profileas TIFF jpeg PSD etc .?

Yes, in the export dialogue panel pick a TIFF or PSD setting, and then set the colorsync profile selector to a cmyk-profile,
You need to have installed cmyk-profiles, however;
most of my colorsync profiles were installed by photoshop.
You will find the cmyk-profiles in the system library:
/Library/ColorSync/Profiles/

When exporting versions (from DNG-to JPEG org size) they get very smal?

when exporting versions in aperture (from DNG-to JPEG org size) they get very smal? Why cant they stay the same size and kvalety as the DNG?

How are you exporting? If you are dragging the image out of Aperture you get the preview, you are not exporting the version.
If you are exporting then the most likely reason for what you see is the setting on the Quality slider. Remember JPG images are compressed and you will always see a difference between the original and the exported JPG.

Aperture JPEG export observations

I exported 3 jpegs full-size with the following compression quality number (1-12):
10 resulted in a file of ~ 2.5 MB
11 resulted in a file of ~ 3.5 MB
12 resulted in a file of (incredibly!) 10.5 MB !!
Why is there such a big jump from 11 to 12?
And yes there is default noise reduction enabled and no changes were made between the 3 exports.

I see the same behavior exporting D50 NEFs as JPEG with quality at 11 vs 12, and I have never seen a good explanation for this.
I find that high quality conversions from Nikon's own software give me a file size in between Aperture's Q=11 and Q=12 export results, which I find to be ideal. For many of my exports I feel that the Q=12 result is too large, and the Q=11 result too small, i.e. I fear that too much information has been lost due to compression if I were to want to make a large high quality good print.
Honestly, though, I can hardly tell any difference in the image between Q=11 and Q=12, even pixel peeping at full size.
I would love to see a export quality setting that produced a result in between what we currently get with Q=11 and Q=12. It does seems to be a large gap.

Aperture JPEG export behavior: How does it handle non-versioned JPEGs?

I routinely export Aperture images as 98% JPEG. I understand what this does for my RAW images and I think I know what Aperture does for JPEG originals that I've edited.
I wonder, however, what it does for my JPEG originals that I've not edited. I want it to simply export the original, but Aperture might instead decompress the original and recompress at 98% JPEG. This will usually increase the file size and reduce the image quality, it's clearly not a good strategy.
If I were working in iPhoto it would, in this case, follow the better strategy of exporting the original, untouched.
So what does Aperture do?

"Export as 98% JPEG except when there's no version and the original is JPEG. In that case, use the original JPEG".
Except that it's "when there's been no adjustments at all to the image, no keywords or other metadata changes, no time zone changes, the original JPEG is already in the correct colour space and has the pixel dimensions that I want."
There's no easy way of making an AppleScript that can find out all that information, particularly whether any image adjustments have been made, or if you have added metadata which isn't in the original file.
Ian
P.S. From your talk of 'versioned images' I'm assuming you've got the preferences set to make a new Version if you make any image adjustments? That might make an AppleScript possible, depending on whether you do anything with metadata, and how often you use Stacks.

Export to jpeg: Show jpeg file size prior to export

Photoshop save to jpeg dialog box shows the jpeg file size associated with each jpeg compression level (1 - 12). Lightroom export dialog box does not show jpeg file size. Showing the expected jpeg file size is useful when needing to limit file size while maximizing jpeg quality. For example, some email applications limit attachment file size; some photo hosting sites (e.g., Zenfolio) limit file size to 12mb. If I export a cr2 file at 100 quality, it may result in a file size of 14mb. However, I cannot determine this until after I export. Then I may try 90 quality and find that the resulting file size is only 8mb. So, I try 95 quality, and get a 12.5mb file. This iterative process is a waste of time. I need to se the file size resulting from each jpeg quality setting in the export dialog box.

I have tried trashing the plist file. The files look fine through the media manager when copied to the other profile. They look like they are suppose to. The small videos also look fine when played on that computer. Unfortunately our other mac pro computer doesn't have final cut so i can't open and play proress files and my laptop, due to the extreme resolution can't be played on my laptop with final cut studio installed. Tomorrow i'm going to install the proress decoder on the one mac pro to check the files and make sure the self contained is checked but i'm almost positive on that. Other than nuking the profile i don't know what else to do. This is really weird.

Aperture 3 problem export (or share) photos via outlook

I have Aperture 3.5.1; Outlook for Mac 2011 version 14.3.9
When I try to export (or share) photos via email using Outlook I can see the little wheel on Aperture spin saying "exporting" however it does NOT open a new email window and I cannot find out where the photos have gone. In Aperture preferences I have set Outlook; Tiff 8 and sRGG; 300dpi and medium size.
It used to work however I simply cannot figure out the problem. I can export to desktop and move them that way but extra steps and unnecessary. Any help great appreciated.
Thanks

There are some known problems with Outlook Mac 2011 in Mavericks 10.9.1 - see: http://www.macwindows.com/Mavericks-10_9_1-fix-OS-X-email-snafus-but-Outlook-not -mentioned.html
Since I don't use Outlook as Mail client, I don't know, if the Mavericks Update to Mavericks 10.9.2 fixed this. But it cannot hurt to update, since this update included bug fixes.

Aperture won't export all photos to Mail

Most of the time, Aperture won't export all my chosen photos to Mail. If I chose 8 photos, it may only export 4 of them and no matter what I do, nothing changes. Tried it on Entourage and it was exactly the same. Size is not the issue, I'm sending them in small sizes and the total attachment is about 1 MB. Anyone had this issue and know what to do? I do have NIK plug ins installed if that helps any.

I would suggest you do a library repair to see if that clears it up.
