Distorted Thumbnails

you’re maxing out your ram

"Dennis Hughes" wrote in message

I am running into a number of my jpg thumbnails in Bridge being distorted, as if they are being viewed through wavy glass. When they are opened in PS CS2 they are just fine. A "save as" results in another image that has a good thumbnail.

I’m running XP Pro and this is happening to maybe 1% of my images.
Any ideas?

I don’t know if what Canongirly is saying is right. I can imagine it can be because the resizing doesn’t using any resampling. Maybe you can post a screenshot somehwere?

Here is a page where I have posted two examples of jpgs that open just fine, but are badly distorted in the CS2 Bridge.

Thanks,

Dennis

Hmmm, are the images the actual images or screenshots? Also, the screenshot that is shown directly on the page is downsized, so it is impossible to see what has happened to the actual image.

But if image 2 ( http://www.partyarchesllc.com/images/p1010266.jpe ) is the result of displaying the image through Bridge, than anti aliasing (or better: the lack thereof) really is your problem. Notice the rigid edges on the roof of the car in front and the grill of the car behind it.

Good luck,

I just discovered a very interesting fact about this issue; The thumbnails are distorted in PS CS2 Bridge, but in PS CS’s browser they look normal. My second computer still has CS on it and I checked just for the heck of it.

The links on the web page http://www.partyarchesllc.com/imageissue.htm are to the actual image files. The screen shot is from the CS2 Bridge.

Think I might send this to Adobe.

Anybody know enough about the inner workings to comment?

Could you post a full-size version of this image (just cause i’m curious)? But I don’t think aliasing will be the issue.

If you click on the link to "image 1" it will open the original image.

Strange, there seem to be different screenshots than before… These ones are very usable.

Although I can’t confirm this right now (mainly because I don’t have Adobe Bridge), I have a pretty good idea on what’s happening.

JPEGs can store thumbnails in their headers, more specifically the EXIF header. Camera’s often do this, because these thumbnails (160×120 pixels in dimension, if I’m not mistaken, and apart from being smaller they are also fairly low in quality) are much faster to load than the full image, which makes your life a lot easier when previewing the shots you made.

It appears that Adobe Bridge uses these thumbnails instead of the actual image when previewing your JPEGs. So you will find that will almost only happen with JPEGs from digital camera’s. I don’t know anything about Adobe Bridge, but what you can do is use some freeware program to strip the thumbnail out of the header. This will not only solve the problem you are having with Adobe Bridge (although it is only visual in nature, your images are fine), but will also somewhat reduce the size of your images.

Hope this explanation makes things a bit clear 🙂

Good luck,

Martijn,

Makes sense to me. I’m coming to the conclusion that this is not a Bridge probaem, but a problemin the file itself.

If I open and resave the preview/thumbnails are just fine.

Dan from Adobe solved this one.

The extension jpe needed to be changed to jpg, AND the cache purged. Once that was done, the image displays normally in Bridge’s preview/thumbnail mode. Adobe is working on this issue.

Thanks guys,

Dennis

Funny, the first thing I downloaded is was to change the extension to get the associations right – never figured it would cause a problem with software like that. Could Dan also confirm my hypothesis that the quality was low due to a thumbnail being resized instead of the original image?

BTW, the thumbnail might have been one made by Bridge, not the one in the EXIF header, BTW.

But thanks for posting the solution, always good to learn something.

Greets,
