Pixel aspect ratio что это в фотошопе
С установкой CS2 обнаружил неприятность - при открытии любой фотки включается Pixel Aspect Ratio равный 1.014, то есть визуально фотку растягивает по горизонтали. Это - свинство.
Отключение коррекции во вкладке View действует, естественно только на одно окно. Ковырялки в настройках не воздействовали, поскольку соответствующего пункта нигде, естественно, нет.
Суть сложности изображена в аттаче.
Помогите от гадости избавиться, ибо очень сложно работать, когда приходится каждый раз лишние клики делать.
P.S. В остальных версиях шопа всё пучком, а как же иначе. Перейти обратно на CS или седьмой - не предлагать, поскольку ущербны слишком.

Любой ? Т.е. New(Square Pixels)->Save -> open = AR=1.014 ?
Попробуй "Ignore EXIF information" в настройках. Ч-з Acd see посмотри Aspect ratio у файлов. Что за камера?
Может виде/web camera,- тогда ясно.

Это равносильно отключению коррекции, только непосредственно влияет на данную фотку. При этом на остальные не распространяется. Пересохранять таким образом весь свой зоопарк - увольте!

Нет, квадратные изображения он распознаёт правильно. Я говорю про фото.
Фотоаппарат - цифромыльница Canon.
Отключение распознавания метатегов не влияет, фотки всё равно открываются как [scaled].
К слову, прочие фотошопы открывают именно как Square.

Мой пятый ACDSee вывалил всё что нашёл в метаданных, но из ratio там есть только Digital Zoom Ratio равный 1, но он тут явно не при чём.

Провел эксперимент в шопе CS2. Изменил в фотке Pixel AR, сохранил JPG. ДЕЙСТВИТЕЛЬНО Pixel AR ни ACDSee 7, ни сам шоп в метаданных не показывает (скотина). Вылечил таким образом. Пересохранияем другой прогой файл. Например ACDSee "Convert File Format" в TIF.

Проверил. Хм. Есть фото с трёх аппаратов (серия PowerShot, два S и один G), откопал у себя ещё чьё-то сфотканное EOS-ом (причём она была пересохранена в Image Ready).
Все фотки как одна со всё тем же значением 1.014.

Закинь фотку, интересно даже стало! Особо про то, что на любых, как ты говоришь Canona`х. Я бы все-таки пакетным преобразованием лечил по мере надобности.

Гружу в фотрошоп черно-белые картинки, а они по дефолту открываются с искажением пропорций. Опытным путем нашли, что искажает все автоматически грузящаяся галочка View - Pixel Aspect Ratio Correction (Photoshop CS). Что это за зверь такой, и как бы сделать так, чтобы картинки каждый раз без этой функции сразу открывались, в нормальных пропорциях?
Поставить в настройках соотношения сторон пикселя -square (квадратный).
Живут настройки тут Image-Pixel Aspect Ratio. По дефолту стоит(и должен стоять если вы точно не знаете зачем вам иное) как раз square
Спасибо ;) А чтобы все картинки сразу с такой настройкой открывались, сделать, по-видимому, нельзя?
Иное мне точно не надо. это при разбивке пдф-а на тифы он такое делает зачем-то
где происходит «разбивка PDF'а на тифы»? попробуйте растрировать постранично прямо в фотошопе. тогда этой проблемы быть не должно.
В акробате
Потому как не могу в CS понять, где та самая функция "импорт пдф", которая импортирует пдф-ные картинки as it, без пересчета разрешения и вылета этого дураЦкого окошка "вам в каком разрешении растрировать?". Ни в каком мне не нужно растрировать. Мне 1:1 импортировать нужно. Если подскажете, как, буду благодарна. ;) В 8.0 эта функция была в File-Import pdf-Image, а в CS-ке ее куда дели, не могу понять.
8.0, насколько я помню, это и есть CS. а CS2 — это уже Photoshop 9.0 ;) но не суть.
что, по-видимому (я не уверен), происходит. тот, кто делал этот педеэф поставил в своем любимом фотошлепе именно тот аспектрацио (см. выше), который не нужно ставить аспект :) а у вас стоит другой. но что такое «один к одному»? пропорции изобюражения сохранятся. ставите нужное вам разрешение. вгоняете в нужный размер. в чем проблема?
между прочим, на моем восьмом шопе этот самый «импорт пдф» настолько по-дурному работает, что я им совсем не пользуюсь. попоробуйте как-нибудь из экранного (!) педеэф с помощью этого импорта сделать читабельную картинку :)
Ну да, CS2, сорри ;)
Следовательно, мне-таки на всех файлах ее менять, ы?
1:1 - это значит, что файл дожен открыться в том же разрешении и размере (и прочими всеми характеристиками), с которыми этот файл был засунут в пдф.
зы: только что на другом компе открыла на 8.0 этот пдфник через File-Import pdf-Image - все нормально открыватся. А вот где это ф-я в 9.0? Через файл-оупен - ни в какую не хочет ;(
Photoshop can create images of various aspect ratios so that they appear properly on devices such as video monitors. You can select a specific video option (using the New dialog box) to compensate for scaling when the final image is incorporated into video.
The Film & Video preset also creates a document with nonprinting guides that delineate the action‑safe and title‑safe areas of the image. Using the options in the Size menu, you can produce images for specific video systems—NTSC, PAL, or HDTV.
Safe zones are useful when you edit for broadcast and videotape. Most consumer TV sets use a process called overscan, which cuts off a portion of the outer edges of the picture, allowing the center of the picture to be enlarged. The amount of overscan is not consistent across TVs. To ensure that everything fits within the area that most TVs display, keep text within the title‑safe margins, and all other important elements within the action‑safe margins.
A. Action safe area (outer rectangle) B. Title safe area (inner rectangle)
If you are creating content for the web or for CD, the title‑safe and action‑safe margins do not apply to your project because the entire image is displayed in these media.
Preview options
To help you create images for video, Photoshop has a Pixel Aspect Ratio Correction viewing mode that displays images at the specified aspect ratio. For more accurate previews, Photoshop also has a Video Preview command that lets you immediately preview your work on a display device, such as a video monitor. To use this feature, you must have the device connected to your computer via FireWire (IEEE 1394). See also Preview your document on a video monitor. For more information on FireWire (IEEE 1394), see Apple’s website.
Other considerations
Both Adobe After Effects and Adobe Premiere Pro support PSD files created in Photoshop. However, if you’re using other film and video applications, you might consider these details when you create images for use in video:
Some video-editing programs can import individual layers from a multilayer PSD file.
If the file has transparency, some video-editing programs preserve it.
If the file uses a layer mask or multiple layers, you might not have to flatten the layers, but you might want to include a flattened copy of the file in PSD format to maximize backward compatibility.
Frame aspect ratio describes the ratio of width to height in the dimensions of an image. For example, DV NTSC has a frame aspect ratio of 4:3 (or 4 width by 3 height) and a typical widescreen frame has a frame aspect ratio of 16:9. Some video cameras can record various frame aspect ratios. Many cameras that have a widescreen mode use the 16:9 aspect ratio. Many professional films have been shot using even wider aspect ratios.
Pixel aspect ratio describes the ratio of width to height of a single pixel in a frame. Different video standards use different pixel aspect ratios. For example, many computer video standards define a 4:3 aspect ratio frame as 640 pixels wide by 480 pixels high, which results in square pixels. The computer video pixels in this example have a pixel aspect ratio of 1:1 (square), whereas the DV NTSC pixels have a pixel aspect ratio of 0.91 (nonsquare). DV pixels, which are always rectangular, are vertically oriented in systems producing NTSC video and horizontally oriented in systems producing PAL video.
If you display rectangular pixels on a square-pixel monitor without alteration, images appear distorted; for example, circles distort into ovals. However, when displayed on a broadcast monitor, the images appear correctly proportioned because broadcast monitors use rectangular pixels.
When copying or importing images into a nonsquare pixel document, Photoshop automatically converts and scales the image to the pixel aspect ratio of the document. Images imported from Adobe Illustrator are also properly scaled.
A. 4:3 square-pixel image displayed on 4:3 square-pixel (computer) monitor B. 4:3 square-pixel image interpreted correctly for display on 4:3 non-square pixel (TV) monitor C. 4:3 square-pixel image interpreted incorrectly for display on 4:3 non-square pixel (TV) monitor

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?

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

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 :-)

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?

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.

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.
