I have just upgraded from PS 7 to CS.

Whenever I open a tiff file now I get a dialog box that says "Pixel aspect ratio
correction is
for preview purposes only. Turn it off for maximum image quality"

Then I close the box and the tiff opens all squished up and unuseable. When I go
under
IMAGE > PIXEL ASPECT RATIO > SQUARE the images goes back to normal but PS help
does
not explain how I turn "pixel aspect correction" off so I don't have to go
through this song
and dance evertime I open a tiff?

What are these TIFFs? Where are they coming from?

You are seeing this dialog because you are opening a TIFF that does not have
square pixels. This is quite rare, and only TIFFs from a handful of
applications, like FAX software, doesn't have square pixels.

If the TIFF is coming from a program that *does* use square pixels, then the
program creating the TIFF is writing it incorrectly.

Actually, the OP is viewing a normal TIFF, but has the "Pixel Aspect
Ratio Correction" turned on in the View menu. This new feature of CS
allows people designing images for video production to artificially
expand the square pixels into rectangular pixels used by video. It is
intended to enable a preview of how your image will look when
converted to video format.

To the OP ... just shut it off! It's in the "View" menu, as your User
Guide clearly states.

Well you didn't answer his question now did you, he wanted to know how to
turn it off, not why it comes up on his screen.

I also get this Pixel Aspect problem when I open scans in Large Format Black
& White Line Work (Architectural Drawings size A0, A1, B1, etc.)

It's annoying, and I'd like to turn it off too, seeing how I don't work on
Video or Images from Video.

So if you know how to turn it off, please respond. Please don't post
telling us we are scanning or opening pics that aren't square pixels...DUH!
We know that....

Thank you guys and gals!

Chris

With no files open, go to the View menu and turn it off.

If you open files with non-square pixels, the prompt will still appear.

Doesn't work, you can only turn it off with an image open. With no
image open the option to turn it off is greyed out in the menu.

This is an extremely annoying little "addition" to CS. Considering
there is hardly anything new in CS I don't know why I bothered
upgrading. The big selling point of CS, shadow/highlight adjustment,
is just for people that don't want to learn curves.

BTW, these are regular old bitmapped tiffs.

If you're using Windows2000 (/XP?), right-click a tiff and check its
properties->summary to make sure the horizontal and vertical resolutions
really are the same. If so, how about resetting Photoshop's preferences
(ctrl+alt+shift just as PS starts up)?

So, nobody's posted an answer here in seven years. Yeesh. How is this the first hit in Google, then?

After reading this, I fished around in the photoshop (CS3) menus, and found the submenu: Image>Pixel Aspect Ratio
In here, if you select 'square', then save your image. When you re-open, everything will be all hunky-dory, no prompt, no stretch, no nothing.

Hope this helps other people who stumble across this page later!
