I am wondering if it just me and a couple of others who are seeing pixelated images in a Light Table in 3.1.1?


With Aperture 3.1.1 set to all defaults in Preferences, I create a new light table (either empty or with pre-selected images) and then drag images to the light table.

The images are small on the table. They appear to be lower quality than the images in the filmstrip to begin with. Resizing the images exagerates the problem and reveals unclear and/or pixelation.

I have done a clean install of Aperture 3 and updated to 3.0.3 and the issue does not exist. Light Table images are fine whether resized or not.

*What I have tried so far:*

1 - Clean install of OS X 10.6 and updated with 10.6.6 combo installer (repaired disk permissions once installed), then install Aperture 3 and updated to 3.1.1 (repaired disk permissions once completed). Import new images from Nikon D80 (both RAW and JPEG) and tested light table. Same issue. Then imported new .cr2 files from a friend's Canon, which all had the same issue.

2 - Copy APTS lesson files and library to drive > open with Aperture 3.1.1 (upgrade library when prompted). The existing images in that library behave correctly in Light Table, but newly imported images into that library display the image degradation / pixelation in light table.

3 - In all cases, I have tried to delete / generate Previews as well as Thumbnails. None of these have sorted the issue.

Note - it almost appears to me that the images used on the light table are actually small thumbnails that are low quality on the light table and any subsequent resizing pixelates the image.

Note #2 - the strange thing in all cases is that using the loupe tool and panning over the images in the light table shows high-quality image.

I am trying to determine if it is my machine (or procedure) specifically, or if there are others experiencing this in large numbers.

I have 8 GB RAM and the nVidia 8800 GT upgrade card in my machine. Whether just Aperture 3.1.1 is installed or with all my normal software, no difference in Light Table behavior.

Looking for comments as to whether users have no issues like this or any who do.

I have already sent a report to Apple.

Thanks in advance for any comments.

    I have exactly the same issue with the Light Table behavior -not sure whether this is as intended, or a bug though. Did you hear back from the customer support, or find a solution by yourself?

    In 3.0.3 the light table starts off smaller (with larger grid squares as if zoomed in) and dragging the images onto the table show the same quality image on the table as in the filmstrip. In 3.1 (and 3.1.1) the light table starts off much larger (with smaller grid squares as if zoomed out) and dragging an image from the filmstrip results in a smaller sized thumbnail showing on the light table at the lower quality.

    Haven't had a chance to try this out but....

    What if before you place images on the light table you zoom in to mimic the look in 3.0.3 then place the images. Does that change anything?

    I just upgraded to Aperture 3.1 and I'm having exactly the same problem described in this thread; very low resolution for pictures on the light table. Is there a solution now?

    I have exactly the same problem, using OS X 10.6.8 and Aperture 3.1.2. Light table is useless as is.

    Closing this thread as it would seem that almost no one else sees this issue.


    I think the reason for the low number of responses is that not that many people use the light table. 


    So I just tried it using OS 10.6.8 and A3.1.2.  I put two images on the Light Table and scaled one image up as large as the Light Table would allow.  Both images looked fine, but the scaled image did appear slightly softer than the image that was displayed simultaneously on the secondary monitor.  Interestingly, I saw the pixelation- only in the unscaled image- when I dragged Aperture's main window over to secondary monitor, but the image cleared as soon as I began to scale it.


    I'm wondering if there's a hardware common denominator among the users who are experiencing this issue.
