Exporting smaller size JPEGs

In managing a library of thousands of scans of LP record covers I typically save one very large .psd file. I save a 2nd cropped reduced .jpg for use in FileMaker and iTunes and possible web use.
Now with Aperture I don't need to save an additional copy of the smaller file. But a resaved JPEG from GraphicConverter at 300x300 is approx. 45k. The same cropped version exported from Aperture is about 245k. I'm wondering if this is because GConverter allows me to save without a resource fork. Or is it all because of the quality of the preview chosen in Preferences?
Does exporting for email reduce a file size more than a version export?

The curious thing is that when I try to export full size jpegs through the email function,
Do you mean exporting through the e-mail the EXACT SAME photos that you were discussing above?
Have you done any cropping of the photos? What is the size, in pixels, of one of these photos according to Lightroom? What is the size, in pixels, of the corresponding exported photo, according to your operating system?
Can you show us screen captures of the export dialog box?
At this time, I am not going to deal with the print at A4 size being pixelated, as printing introduces a lot of other places where something can go wrong. To see if the problem is in the export, I want to know if you look at the exported photo outside of Lightroom, does it appear pixelated or not?

  • Exporting full size Jpegs from DNG converted files

    Hi there
    I imported some RAW files into Lightroom 4, which I then copied/converted to DNG, then edited them. I now want to export them as full size, high-quality jpegs but I only seem to be able to export them at a maximum of about 800kb, which is far lower than full-size. Is this to do with first the conversion to DNG from RAW on the import? Am I best copying them from raw and not converting them to DNG at all? Next question is, will I have to import the original RAWs again and re-edit them to be able to export as full-size high quality jpegs or is there some way to not have to do them again? Many thanks, Sophie

  • 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 small size images (for may web galleries thumbnails)

    Hi,
    when I export versions whith the preset I create (jpg 100 pixels) the lower size file created is 50KB!!!??? also with "0" JPG quality (max compression) and a very small quality (not usefull for me). If I try whith the same images version exported to "Aperture web gallery", the thumbnails are exported in 4-8 Kb size for 100x62 pixels and a good quality!!!
    But I have my ASP pages and DB on the web and every week I have to publish 3-4 new galleries and 2-3 slide show. All is presetted, and I only have to export thumbnails and large images and upload them via FTP on my web server.
    I bought Aperture in order to be able at the end of my workflow, to export in a folder and directly upload my images and thumbnails without using another application like now! Any experience?
    (Master files are Canon .CR2 and export is setted at 72 DPI, 100 x 100 pixel, without adjustement, only file are renamed vith a 3 digit counter.)
    I also whould like to know what is the requested knowledge to realize a plug-in with Aperture SDK?
    Many thanks.(sorry for my english language)

    Hi,
    after posted my first question, I have noticed that a very strange things occurs to the aperture exported jpg files. I'm veryy new with MAC and i'm working on both MAC and WIN systems; when I copy from Mac to Win the folder where file were exported from Aperture, I see a double serie of file: the first one is the regular namefile.jpg and a second kind of file named "._namefile" (012.jpg and ._012).
    The first can be used and distribute also in win systems, and is very smaller in size than the orginal created by Aperture; the second is always around a size of 50-60 Kb and is not know by win systems. The sum of the two files seem to be the size of the original MAC/Aperture created file!?
    So, in win sys, a 150x100 pixel file is about 6-8 Kb (exactly what I'm expecting from it), and on Mac the same file is 60 Kb!!?? A MAC file of 480 x 320 pix at medium quality is about 140 Kb, but it is 80-90 Kb when copied on a win system (the correspondant ._nomefile is always around 50-60 >Kb size.
    You know why and how can I obtain optimized files for web from Aperture?
    Many thanks.

  • HT1152 When exporting photos to file they are being downsized even though i export as origonal jpeg size

    When exporting photo files to new folder my computer downsizes them even though I export as origonal jpeg size

    Could you please give an example with specifics.
    Right click the original and select Get Info. Size is the second line under General.
    Do the same for the file after it is moved to the folder.

  • Export file size is different from the original raw size

    Could someone explain to why, when the original size of a raw file in a folder is about 11mb. But when in Lightroom is shows about 7.1mb. When I export it to a jpeg the size becomes around 3.5mb.
    I know that sRAW1 file is 7.1mb as stated in the book. But why does it go down to about 3.5mb when exported to jpeg.
    Is there a way to export it to the a higher size? Like 7.1
    I used sRAW1 in a canon 50D.
    Thanks,
    Ray

    The "actual" size of you images file is measured by this basic formula, 8-bits is one byte. Each pixel has one byte for the Red, one byte for the Green, and one byte for the Blue colour channels. So, we have 3 bytes per pixel. Multiply the total number of Mega Pixals of your camera's sensor by 3 and you have the true size of an 8 bit image file.
    How this image will end up in a final file size depends upon the amount of compression you choose to apply.
    The more complex the image, the harder it is to compress without some degradation of image quality. So the original size of an image will not always be a guide to its size when compress. For instance an image with little or no sharpening applied will compress to a much smaller size than the same image with a large amount of sharpening even though the same compression settings were used on export.
    If you wish to resize your images on export from LR in specific megapixals (and therefore MB's) then LR/Mogrify has this functionality.
    There is a nice simple explanation of this here

  • Original size Raw to JPG export not exporting correct size

    I'm having a problem with the export of RAW to JPG at original size. I have raw images of 4941 × 3295 (125mb), when I export selecting "JPEG-origional" size I get resulting jpg's of 800 x 533 (95kb) 
    If I select JPEG-50% of original size I get correctly exported images of 2471 × 1648 (589kb)
    Why would the original size export not work?

    Have you checked the "JPEG original size" preset? Select the preset on export, then switch to "Edit" and see, what is selected. Sometimes this preset is redefined to a smaller size.
    When you edit the preset, the "Size To" pop-up should be set to "Original size". If it is not, set it back.

  • Exporting RAW to JPEG and TIFF

    Evaluating LE to hopefully improve some workflow. I noticed however, that when export to a JPEG or TIFF format the file size seems much smaller that I'm accustomed. A D100 9.5MB RAW file converts to appx 2.7Mb JPEG at 100% and appx 7MB in TIFF. Currently when I convert I get a 17-20MB JPEG. I'm I missing something in the setup or is this the larger file size LE produces.
    Murray Edwards

    Excuse me Lightroom. I currently use Portfolio 8 to review and tagged a large number of images for production. They have a conversion process that allows you to convert a NEF file to JPEG or TIFF. When converting to from a NEF file that is appx 9.5MB in size to a JPEG at 100% @300DPI which is what my clients require, it produces a a JPEG file that ranges from 17-23MB depending the amount of information. But I still have to pull that image into editing SW to do some cleanup or slight exposure adjustments. It was my hopes that by using Lightroom, I could slimline a couple of these processes. But if LR only provides a exported JPEG file size of what I've seen thus far, then I would unable to accomplish this.
    Is this better clarification of my question?

  • Export original size not original size

    The native RAW resolution of my camera is 6016x4016. When I try to export jpegs as original size, they come out 1798x1200. If I export as TIFF, they come out full size (but 20x as large a file as jpeg.) If I export at 50%, they come out 50%. This is only happening on my iMac, not my MacBook Pro. How do I get aperture to let me export a full size jpeg again?

    Open the Image Export Preset and make sure that the settings for the Image Export Preset that you are using match the description.
    If that's not it, post back.

  • Exported image size

    I shoot a canon 30D which produces RAW files about 7mb. When I export the versions as full size Jpegs, they get knocked to around 250kb! What is going on? That seems like an extreme amount of compression to me. Any ideas as to what I am doing wrong? Thanks
    HPL

    Go into the export presets and have a look at both the output dimensions and the compression settings.

  • How to compress unedited movie to smaller size?

    I was wondering if theres a way to compress the existing imported video file that is unedited to a smaller size. I ahve a good size hardrive but I don't have time to edit all the camcorder movies I take so I leave them untouched in their folders in the meantime. The problem is that the unedited copy in imovie is 12-15GB and it sure adds up if you have more than one video.
    I know I can export it to a smaller size but it will combine my video into one which I don't want due to editing purposes in the future.
    Please let me know thank you.

    which I don't want due to editing purposes in the future
    If you mean that exporting will join your project into one clip, that's usually not the case. Clips are usually preserved as true clips when you export to the camera, then import them back to iMovie.
    Try it to see how it works for you. If it works the way you want, then that's a good way to reduce the size of the project. (If the original video was imported as a single clip, that may be problematic.) If nothing seems to work, try adding a black slug between clips before exporting. Or a title over black.
    Otherwise, there's no good way to save the project in a compressed format and also preserve all the quality.

  • Any experience with small size text?

    I'm creating an iPhoto book as a birthday gift and want to include a time line of historic events over the past 50 years. I'm using Adobe Indesign to create the time line and will convert to a jpeg image to include in the book over two pages.
    My smallest font size will be 7pt Ariel. Has anybody had experience including text in an image at a small size, and if so, how well did it reproduce? I can print this out on a laser printer at home and it prints perfectly well, I'm not sure if the print method Apple uses will reproduce text in the same way. At the end of the day I can insert the pages by hand with the laser versions, but curious to know if the iPhoto book printers can save me the hassle.

    Hi, Tony. Printing the document directly from InDesign and printing it after it's been converted to a .jpg file may yield radically different results, particularly where very small text is concerned. Create a sample document using the font and size you intend to use in the book, then save it as a .jpg at various resolutions and print each of them from Preview on your own printer. This will give you at least a rough indication how high a resolution is needed for the compressed and rasterized type to be legible. Generally speaking, it's a lousy idea to include type, especially small type, in any raster image. By extension, it's probably not a good idea to use a raster image as a vehicle for adding type to a book, as you propose to do, and as iPhoto's book production standards require you to do if you want to use the iPhoto book service and include your text. But by experimenting at home with resolution (and perhaps with the level of jpeg compression that's applied) before placing your book order, you may be able to make the result look acceptable.

  • IMovie Reduce Exported Video Size

    I am super new to iMovie. I am using iMovie 10. I added a video clip of size 90Mb in the iMovie. I did some slight editing like adding some text and an image. I exported it using the Share file option with the lowest SD quality option and the file size is more than 500Mb. I imported this 50Mb file in the iMovie again, did some editing and exported using the HD option 720p and now the exported file size is more than 1.1Gb.
    I did some searching and realized that there was an option to export it as a QuickTime movie which gives many compression options. But looks like that option was in iMovie 9 and has been removed from iMovie 10.
    Is there any way i can reduce the file size or is there any option to export the file size with minimum file size?? Thanks!

    There are less options that there were in iMovie 9 but Share to file produces a Quicktime movie and you can choose the resolution.  Obviously there is no sense in choosing a resolution higher than the original clips.  Lower qualities produce smaller files.  The other share target options are tailored to the target - the smallest movie is obtained by sharing to e-mail but of course the quality is very poor.  For details see:

  • Is there a way to make the Toolbar Icons small size?

    There is an option in almost every app to make the tool bar icons small size. My suppress is this is not the case with AP3.
    Hard to believe.

    nope.
    all versions prior to a3 had it but for some reason they removed this option with aperture 3.
