Aperture Vers. 3.6 Vignette issue

Have you checked, if the intensity slider for the vignette is set to a negative value?

With these settings the vignette will lighten the borders instead of darken them:

I have the same problem, using a Mac Pro 2008 with El Capitan. Probably a lack of support issue now... it appears vignetted in Aperture, but turns white on export, whether I have the intensity slider in negative or positive. Very frustrating!

Do you have any other adjustment enabled, perhaps Straigthen or Curves?

For me, the vignette is working well, but I have not tried all combinations with other adjustments.

The problem may be related to the "Straighten" problem, where a combination of Straighten and Curves is giving random results at export.

I did have crop enabled, but not straighten.

As a test, I reverted to original, applied only the vignette, then exported. What appears as a black vignette in Aperture gets exported as a white one... so I'm still none the wiser.

Try to export with a different color profile. make sure it is standard profile, for example AppleRGB.

I am not able to reproduce the problem, whatever I try when exporting JPEGS. Are you exporting at a different image format?

Okay - I've got it!

I needed to go to 'Export' rather than just drag and drop a copy of the photo into a folder.

I have been drag-n-dropping photos for years, but only recently I've noticed the white vignette on export issue. However, this does seem to be the solution, so thank you!! (I think my color profile was always AppleRGB anyway...)

Merci Léonie 🙂

Good to know, that this is the issue.

But drag&drop should be working. It is exporting the standard preview image according to your preview preferences in Aperture. The previews should be o.k. as well. When I drag&drop, the vignette remains black.
