I have recently moved from iPhoto to Aperture.

When I import photos from CD they are full of noise. It doesn't happen when the photo first launches... it seems to render it and suddenly goes really grainy (in a digital way). The photos are fine in iPhoto.

 

Any ideas?

    They are also fine if I leave Quick Preview checked....

    Unfortunately I couldn't find anything helpful here.

    It seems to be something to do with Preview Mode.

    The images are JPG...

     

    I might be about to jump ship to Lightroom as it seems to be able to render the photos fine.

    Hi,

    Do all photos do this, or only the ones you're importing from CD?

    How did you import them?

    What settings do you have for the Previews in the Aperture Preferences?

    Only the photos from CD

    They are taken on a Lomo, so are pretty grainy. But in Aperture the grain goes very high contrast and digital.

    The preferences are set to:

    Photo Preview: Half Size

    Photo Preview Quality: Half Size

     

    I have just imported a new CDs worth and the same thing has happened

    Nope...

    Are you importing from CDs output from a photo development or an archive of digital?

     

    It is a bit of a mystery especialy as they are fine in iPhoto

    p.s. drop me a line if you find solution....

    Yea had my Ilford B+W film developed at Jessops. so when i got them back they were on disk, a straight import to aperture give me the same problem you have with " in Aperture the grain goes very high contrast and digital" its a killer! even tried dropping them on desktop first and importing + i know there cant be a probalem with them ebcuase they work in finder and the prints look perfect =/ Might hit up the apple shop

    Just a guess here but my guess would be that the images are very high resolution on the CD - if so then I would venture to say that the re-sizing algorithm being used to display the whole image on the screen inside Aperture is the culprit due to throwing away the smooth/similar tonal info and keeping the higher contrast grain when squashing it down to fit on your screen. The quick preview eliminates this due to the way it works based on what info is available to Aperture when it is used.

     

    This re-size algorithm "issue" is the same thing that was causing all the controversy about a year ago with people thinking that sharpening was not being exported even when it was - long story but the short version is that Aperture, iPhoto, and preview appear to have different downsizing methods when crunching down a full res image to fit on a screen - hence they look different.

     

    I shoot A LOT of film and can say that dealing with the scan resolution/grain aliasing/digital resizing equation takes a bit of experience to get right. The good news is that this shouldn't actually be an issue in prints output at 300dpi at all.

     

    If you have an full size example image online somewhere I can probably tell you exactly what is going on here.
