Cropping in PS while Maintaining Aspect Ratio and DPI

I shoot the Nikon D3, RAW (.NEF) and convert through ACR. Through ACR, the DPI is set to 300 DPI; the DPI caries over to Photoshop.
I crop in Photoshop using the crop tool (not marquee). To maintain 2:3 or 3:2 aspect ratios, the crop tool requires the width and height in inches or pixels. If specifying resolution, the document size will crop to that DPI, if not; the DPI is derived from pixel dimensions.
In my case, I’ve been cropping at 2in by 3in (or reverse for orientation). The resulting “real” image pixel dimensions are still very high (correct to crop size) but the document size reported in PS is 2in by 3in with a wildly high DPI. By changing the resolution back to 300 DPI through Photoshop, the document size returns to normal. Therefore the picture has not lost anything; it appears to only be a function of the Meta data. The pixel dimensions remain constant while the document size and DPI change.
It apears that you canot specify an aspect ratio via the crop tool without defining it in inches or cm. You can do it with the marquee tool but the marquee tool sucks for cropping. You can however crop in ACR with the crop tool by merely specifying the aspect ratio (not in inches or cm). In summary, the PS crop tool is based in inches or cm while the ACR crop tool is simply aspect ratio.
What I can do to crop in PS while maintaining aspect ratio and defined DPI. Is there a work-around, magic trick, or something else I can do to fool the PS crop tool into an aspect ratio not based in inches or cm?

Just to summarize:
Setting a dimensioned ratio (e.g., 2 in by 3 in for Width and Height) in the Crop tool without filling in a Resolution value yields a crop with the desired aspect ratio, and without any resampling.
There is no way to specify a ratio with the crop tool, specifically, as the OP has requested, though in a future version perhaps specifying simple numbers there without any units might be a way Adobe could facilitate this. It would be a nice addition and with little downside.
I guess what I don't understand, though, is why the OP cares about the "high" resulting dpi value? It's just a number.
Expanding on this, the Resolution is nothing but a metadata value that can be changed at will (e.g., through Image - Image Size... - uncheck Resample) at any time in the future. There is ALWAYS a Resolution value associated with the image, both before and after the crop (though the crop tool may end up changing it; so what?). In short, the Resolution is just an arbitrary figure until such time as the user wants to use the image for a purpose (e.g. printing).
Always think in terms of pixel dimensions (number of pixels horizontally and vertically) while editing, then think about dpi right before publishing. It's hard to go wrong this way.

Resize flash movie while maintaining aspect ratio?

Hey all,
We have created an extremely content heavy .swf file (1900 x
1400) for a presentation that runs full screen on a monitor at a
screen resolution of 1900 x 1400. I think that was the
resolution... I've been away from the project for a while and I
can't remember. anyways....
now we need to shrink the .swf down to a more reasonable size
so that we can make a cd rom out of it. Probably needs to be shrunk
to about 800 x 600. Is there an easy way to shrink the .swf in
flash from 1900 x 1400 to 800 x 600 while maintaining aspect ratio
and keeping all items on stage?
I sure hope so! I'd hate to have to recreate the entire
thing! It was a HUUUGE project with a ton of content.
Thanks in advance for any help or suggestions!!!!

Hey all.... I am just now working on this project.
I've created my .fla file and I'm trying to load a .swf into
an empty movie clip. It didn't scale down like I want it to and it
was still appearing as the normal size file. So I added the
container._height = 500; and container._width = 800; When I added
the width and height the .swf inside the empty mc container
disappeared!!!!! Any idea why???
Here is my code:
stop();
this.createEmptyMovieClip("container",
this.getNextHighestDepth());
loadMovie("hlhuntyears.swf", container);
container._width = 800;
container._height = 500;
container._x = 0;
container._y = 0;
I export it as an .exe since its going to be a cd rom and
when I double click the .exe to run it I get a blank screen. But
when I take out height and width it shows up but not to the correct
scale. The original file (hlhuntyears.swf) is 1440 x 900 and when I
run the .exe I can only see a tiny piece of it. Can anybody help??
please??

Maintaining Aspect Ratio and Quality

Hello FCE Guru's!
Yesterday while editing I noticed that my footage in FCE that I shot on a canon 7d was not as clear as the raw footage. When I adjusted my settings in FCE using the sequence settings tab, my project became smaller and seemed to regain its clarity.
But the problem is when I import any footage that wasn't already in the project the aspect ratio is bigger than what was in my project prior to adjusting the sequence settings? Even when I try and re-adjust the sequence settings the video stays small while new clips that I import are a lot larger????
So basically I have footage that is smaller than other footage, How do I keep all my footage the same size throughout the entire project?
I would like to know how I can fix this issue and what I did wrong to avoid in the future. I really hope this is something that is fixable as my project is 90% complete and the client is looking for a finished product by Friday. Please Help!
Thanks in advance.

Sorry,
Here is everything:
The footage that is in my timeline and saved to my project is: 1920x1080
*My Easy Setup settings are setup as*: AVCHD Apple Intermediate Codec 1920x1080i60 Format (all Format) Rates (all Rates)
*My sequence settings are setup as*: Apple Intermediate Codec 1920x1080i60
*The footage That I shot and trying to import reads exactl*y: 1920x1080 Apple Intermediate Codec, Integer (Big Endian)
*The issue is*: The Footage that I have in my timeline as well as in my project already seems to be a smaller than the footage that I am attempting to import into my project. The footage I want to import is Full Frame While the footage I already had in my project is smaller in my viewer.
Please let me know if you need any further information,
Thank You.

How to maintain aspect ratio?

I want export a video in 2.35.1, but want to maintain aspect ratio(and get rid of the black bars).
How can I do that in Compressor?
I can only figure out how to compress it. But can’t find any options for maintaining aspect ratio.
I know this can be done with QuickTime 7, but I don't have it.
Currently using Compressor 4

As mishmumken said, custom frame sizes can be
Specified in Compressor Geometry.
But I'm concerned that you may not have preserved the aspect ratio
When you exported from your editor
Here is a great tutorial that describes how to do that from FCPX.

Scaling | Zoom (i.e. "maintain aspect ratio, scale to fill and crop to remove outside boundary"

Hi,
I have a mismatch on the aspect ratio of my source and visual display region. (And please just assume that I can not conform the visual display region to match the source's aspect ratio.)
Flash's default gives me ""scale to fit" which maintains my source's aspect ratio but results in "letterboxing" black space.
Does OSMF (or Flash) have a configurable property that will maintain aspect ratio, scale to fill and crop to remove outside boundary? Or do I just have to code my own solution (e.g. using masking)?
I have a diagram here:
http://flexflashvideo.com/codesamples/2010/zoom_crop.png
Thanks,
g

Have you tried with ScaleMode in OSMF?
     var layout:LayoutMetadata = new LayoutMetadata();
        video.addMetadata(LayoutMetadata.LAYOUT_NAMESPACE, layout);
   layout.scaleMode = ScaleMode.ZOOM;

How do i transform a layer with maintain aspect ratio through scripting in Photoshop?

Hi,
How do i transform a layer with maintain aspect ratio through scripting in Photoshop? I am expecting your reply.
thanks,
Rajiv.s

I don't think your talking apples to apples. First I do not know of any Maintain Aspect Ratio icon in Photoshop. The only icon I think associated with transform is the anchor point icon in the option bar for transform. I think you may referring to the constrain check box in the image size dialog which you can check when resample is checked. Image size effect all layers in the document and the documents canvas size. The document canvas size will be changed to the values in the images size dialog and all layers will be transformed by percentage the canvas was changes while maintaining the layers position over the canvas and the layers I think may be cropped so only pixels over the canvas remain.
I do not know if you know that layers can be any size and have aspect ratios different then the documents canvas.
In your case it sounds like your describing a template that has a canvas size that is 2000px wide be 3000px high a 2:3 portrait aspect ratio. Your image file has a landscape aspect. If you place that image into your template place would by default transform the image so the image would fit within the 2000px by 3000px canvas size there would be a white border top and bottom. You could transform that smart object layer to it actual pixels size activeDocument.activeLayer.resize(100,100, AnchorPosition.MIDDLECENTER); then calculate the size you want to transform its height to. By retrieving the canvas size and the layers boundaries. Divide the canvas height pixel size by the layers pixel height size should give you the percentage you need to use. Make sure you set the ruler units to pixels so your working with pixel values for the canvas and layer size values. The resulting layer will be larger then canvas size keeping the anchor point centered will result in the canvas size masking off both sides. In effect cropping you landscape to a portrait. Note cropping a image from one orientation to the other changes the composition drastically.
If your trying to make a composit like collage you may want to look at my Photoshop Collage Toolkit it will fit images to fill a 2000px by 3000px area http://www.mouseprints.net/old/dpr/PhotoCollageToolkit.html
You could also do centered 2:3 crop that is resized to a 3000px

Pasting from Illustrator to Photoshop doesn't maintain aspect ratio

I have vector artwork that is not aligned to a pixel grid in Illustrator. In CS5, I would be able to paste the vector object as a smart object into Photoshop file that was larger than the illustrator image and resize larger while holding shift to keep the ratio the same.
However with Creative Cloud, if I have a square in Illustrator that happens to be 17.3px by 17.3, then paste to Photoshop in a file that has a larger canvas than the paste, I get uneven horizontal and vertical ratios (width = 18; height = 17). It seems to overestimate the width and make it appear fatter horizontally (which is the wrong aspect ratio). This is very noticeable when vector objects (like perfect circles and small icons) get scaled up in Photoshop.
I have tried unchecking and checking "Snap Vector Tools and transforms to Pixel Grid" but this doesn't seem to fix it.
The only way I've been able to get this ratio to be kept is to create a new document with the size automatically changed to clipboard dimensions (which are the desired 17x17). When you paste as smart object, it now uses the correct aspect ratio.

When you paste an object into Photoshop take a look at your options bar to see if the Maintain Aspect Ratio button is checked. I'm guessing that it isn't which is why Illustrator objects are being pasted at different heights and widths. As you can see in the image below, a perfect circle from Illustrator is being placed in Photoshop at 100.05% and 99.44%. By checking the link button between the two percentages the numbers get locked to the same percentage so that the object is pasted in at the correct dimensions.

Maintain aspect ratio on panel re-size

I think it would be valuable to have a panel attribute "Maintain aspect ratio on resize" that would apply to manual resizing (not maximizing) a panel.
I know this is doable with panel callbacks and EVENT_PANEL_SIZE but a native solution that shows that constraint while dragging a corner would be better.
And given the nature of many of our UIs I think this would often be used.
Any comments before I submit a product suggestion?
--Ian

Since this is now a LabVIEW question, I would recommend to post it in the LabVIEW forum!
The event structure has a "This VI...panel resize" event and you can probably use it to enforce a certain aspect ratio.

Maintaining aspect ratio when transforming

Since I have upgraded to CS6 I've noticed that when transforming an object it does not maintain the aspect ratio even when I am holding shift while transforming. I have to each time check the link button (maintain aspect ratio)

It'll be because 'Snap Vector Tools and Transforms to Pixel Grid' is enabled in 'Preferences > General', an option that didn't exist before CS6. It's actually being more truthful that way because the transformed layer has to become an integer number of pixels wide and tall, anyway, and that's not going to be a perfectly proportional scale in most cases.
See what I mean by trying to scale an 11 x 10 pixels layer by 50%. It's impossible for that to be scaled by exactly 50% in width because the result has to be either 5 or 6 pixels wide (it will be 6). When the 'Snap...' preference is disabled (i.e. the pre-CS6 behaviour) you can scale the bounding box by precisely 50% in width but the pixels don't cover precisely 50% of the original width. When the preference is enabled, you won't be misled by being able to scale the bounding box to precisely 50% when the pixels cannot cover precisely 50%.

Empathy Video Call Doesn't Maintain Aspect Ratio

I'm using empathy 3.6.3-1 with gtalk, and I noticed that video calls don't seem to preserve aspect ratios. Does anyone else have this problem?

Exporting for Web - maintaining aspect ratio

I've been trying to export a 6 minute video as a Quicktime movie file which will be imported into Adobe Flash for use on the web. I've tried 3 or 4 codecs and all of them end up creating a 4:3 image where my source is 16:9. What codec would be best to use and maintain the original aspect ratio and still keep the video file a reasonable size to import into Flash.
Thanks for the help
Carl

Ok, I misspoke when I used the term "codec". I did mean I had tried a variety of settings, none of which preserved my original 16:9 aspect ratio (and this, despite setting "preserve aspect ratio" in the mpeg-4 settings). So, I have experimented with a variety of settings to no avail. I'm sure there is something there - I was hoping someone had the same experience and could clue me in on what settings to use.
thank you,

How do I maintain aspect ratio of images in a replicator?

I have these ai files from a company logo I want to use to build up a wall of the cross shapes seen in the screen shot. My problem is that I have not been able to figure out how to have the replicator maintain the square aspect ratio of the image. What am I missing?
Thanks,
Drew

The only time I've seen something like this is when the original file was saved with an aspect ratio and *non-square* pixels. Adobe applications (Photoshop is the one I know) have presets for video, like NTSC 720x480 in either 16:9 or 4:3 aspect. Taking the 16:9 as an example, what should be 854x480 pixels is saved as 720x480 and the pixel widths are set to be interpreted as 1.21 times wider. In other applications, this will appear to be about 21% squeezed when viewed as square pixels.
If this is the case, (or even *close* to the case) here's what you need to do:
In the Layers list window - at the top -- click the media tab.
Select the image/AI file.
In the Inspector, click the Media tab (again...)
Find the Pixel Aspect Ratio and select (most likely) NTSC D1/DV Anamorphic
Motion will automatically set the 1.21 aspect I was trying to explain at the top. If that doesn't work, select one of the other presets or Custom and type in your own aspect "correction" value.

What is aspect ratio and how can you change it?

Please refer to my other post for more information on these photos. The photos I am referring to are the ones that appear blank in the edit screen.
When I try to export these photos to facebook using the exporter, it says that IPhoto can only deal with photos with an aspect ratio of 3:1 or lower, and that the photos selected have a greater aspect ratio. What is aspect ratio and if possible, how do you change it? This may be directly linked to my other problem with the same pics.

I'm having the same trouble. Zapplications will upload only 1920x1920 photos. With iPhoto I can't get past the automatic ratio of 1920x1440!!! There MUST be some way to customize photo size on iPhoto!! Please help!! I've tried cropping the photo to a square and still can't get past this ratio thing.

Aspect ratio and exporting help, PLEASE!

I've been given a project that was shot on DVCPro HD tapes. The footage was already loaded onto a drive for me. When I bring the clips into FCP, they are 1920x1080 and appear squished in the viewer and canvas. If I click "anamorphic" in the sequence settings, the footage no longer looks stretched.
Great. Now, I need to export the footage to QTs that are a random 620x349, and the client doesn't want the images letterboxed or with bars on the side... they'd prefer that I just crop the images to that aspect ratio. It's for the web.
How can I do this? Everytime I export, I'm getting bars on the sides or a squished image. Thanks for your advice!

That's DEFINITELY not DVCPro HD settings are you SURE they match the clips? AND 1920x1080 is NOT anamorphic.
Also, how are you getting letterbox? Your sequence settings are 16:9 - not letterboxed.

Aspect ratio and render line issue

When I overwrite the video from the source (top left) window to the timeline, it is changing the aspect ratio and a red 'render' line is appearing on the time line.
The video is now zoomed in and pixelated.
I have not had this issue while editing with my other files and the settings seem to be correct. Am I missing something super obvious?
