I've been using Aperture3 for a few months now but only recenly got into more serious post-processing, especially using quick brushes including sharpening. I have just noticed that my sharpening adjustments are not transferred into exported copies, be it jpeg or tiff. I am working with RAW files from Panasonic FZ-150 converting them to tiff in order to apply noise reduction with Topaz plug-in and after that I apply all other adjustments including quick brushes in Aperture. Then I export from Aperture using JPEG - Original Size with Quality 12 and sRGB profile. The resulting JPEG files are not comressed (appx 9MB in size) but the images definitely lack sharpening. This is not a compression issue; if I turn sharpening off in Aperture the images turn identical to the exported copies. So this is definitely a problem with export.


Here is one example where the difference is especially noticeable because the original image was not very sharp in the first place. Yet selective sharpening seems to give very good results in Aperture; however the export version on the left does not contain any signs of sharpening.


I have found a few old threads about this issue but without any solution. I hope Aperture technical gurus are reading and responding on this forum and will be able to help. Has this been fixed? I really like selective sharpening in Aperture but what's the point if I can't share the results. Hope somebody can provide the solution.

    "... In other viewers ... " is the key part.  You are using the Preview program to make your comparisons. I suggest redoing the test with whatever final (Web) destination you will use.


    You probably used 12 for your JPEG quality in order to eliminate that as a variable in your test. In practice, there is often no discernable difference between 10 and 12; 8 is regularly used for Web posting.


    Whatever your results, sizing the file you make by exporting, for the use to which that file will be put, is recommended.

    Andy  you probably know this alread.    KirbyStated.... Stated it well.  But saying it another way... what ever viewer you use view the image at 100% size.
