Pixel Aspect Ratio Correction

[_Jason_The_Adams_]

Some option in Photoshop is resizing the .tif files I'm trying to load, due to their enormity in size. Whenever I load the file it displays a window saying, "Pixel aspect ratio correction is for preview purposes only. Turn it off for maximum range quality."

Great... So how do I turn it off?

Thanks!

Hello Jason,

U should go to View > Pixel aspect ratio correction
that should fix it

How ridiculously simple, thank you. :)

I'm having the same problem. Thousands of graphics get sent to us from a variety of sources outside our company and/or department. Unfortunately, for a large percentage of those, when I open them in Photoshop, I get the "Pixel aspect ratio correction is for preview purposes only. Turn it off for maximum image quality." message. I'm aware of the View -> Pixel Aspect Ratio Correction setting, but unfortunately, that seems to be a very temporary fix (since saving these files isn't an option). What I really want to do is TOTALLY DISABLE Pixel Aspect Ratio Correction. Even for previewing. FOREVER. How can I permanently turn off this "feature" (or serious bug, depending on your perspective)? I have no use for it whatsoever. Some of these graphics have been around for years and years, and we never had this problem back with Photoshop 5 or 7. It's just been since we started using the CS versions that it started.

I already tried looking in the Photoshop Prefs, and didn't see anything. And I've tried a rather extensive web search with no luck. I also tried looking for some kind of setting in the Windows Registry, and didn't see anything useful there, either.

How the heck do I make it go away? At first it was just annoying, but I'm now at the point where it's downright driving me crazy!!!

Hello Janelle H

I just deleted all but the "Square" ratio - now it dosent even ask on opening.
Choose View > Pixel Aspect Ratio > Delete Pixel Aspect Ratio and select the ones you dont need :-)

Mikkel,

It took me several days to find the setting you were talking about, but I ran across it today by accident. In my version of Photoshop, it's under Image instead of View.
Unfortunately, it didn't help. I deleted all the aspect ratios, but when I open up one of those graphics, it just says it's a Custom Aspect Ratio, and continues to display wrong.

Anybody have another idea?

I'm having the same problem. I just tried out image > pixel aspect ratio > reset pixel aspect ratios. Seems to be working so far.

Does the "Don't show again" checkbox on the warning dialog not work?

Hi I'm using Autodesk Maya 2008, and whenever I save a render out as a jpg I get this same problem in Photoshop CS3.

I've done as the above posts say: Image > Pixel Aspect Ratio > Square and View > Pixel Aspect Ratio Correction do indeed fix the image, but I don't want to have to do this every single time I save a new jpg from Maya, and it only seems to happen with jpgs.  I've tried bmp, gif, tif, png, and tga and none of them do this.

[Chris Cox]

This is happening because the JPEG file written by Maya says that it has a non-square aspect ratio.

Photoshop is only honoring what the file says.

You need to inform the makers Maya about this problem so they can correct the metadata they write into JPEG files.

Thanks for the info.  I suppose I could just save out tif and other lossless image types in the mean time. It has it's benefits for quality purposes at least.  But I still want that option to save as jpg for the sake of file size.

Thanks again for the info,

Take care.

try looking at your camera and viewport settings, or your export settings. Certain presets will have non-square pixel aspect ratios. Changing to something with a square ratio, and if necessary render a larger viewport and then crop to your desired shot

Mark, you do realise that this thread is 13 years old?

[MHedinger]

I do. I found it 13 years later bc of a pixel aspect ratio based issue. Who knows, maybe in 13 years someone with a maya export issues will find it again.

I am also facing this problem
