Cropping to exact dimensions

Hello All,
I need to crop some of my pictures to 120px x 120px, but haven't managed to do this, and would like to know where I'm going worng.
Can I work in pixels in iPhoto, if not do you know what unit of measurement do i have to use?
If I can use pixels, in the custom constrain boxes do I just simply type 120 into each box, or do I need to put "px" after the digits?
Regards
JF

Two steps. First, crop to square without worrying about the pixels. Then, export and configure to a maximum pixel X pixel count. The exported file will be exactly what you want without having to remove pixels from the stored file in the iPhoto library.

Crop to specific dimensions?

Is there a way to crop to a specific dimension? I have a 3888x2592 image and would like to crop it to 2400x1600. Problem I am having is I can get it to 2388x1589 or 2420x1619 or finally after many tries (over a minute of attempting) got it to 2399x1599. Is there any way to FORCE it to a specific dimension?
Also, on export I know you can resize an image, but are you able to apply a resize within lightroom itself? Can't think of a situation where I would want to do that, but just out of curiousity...
Thanks,
Clayton

I agree with Andrzej007. Sometimes I need a 1:1 crop
First, to those who ask, "Why not do it during export?" Or worse, "Why would you want to do that?"....   Does it REALLY matter to you WHY I want to do a crop of a specific number of pixels? The fact is some people really need this.
I do a lot of timelapse stuff and build videos at 1920x1080. I shoot full frame (in my case that is 4608x3456). I correct my shots in LR. So, what's the best way to get my images to 1920x1080?
Here's an example image:
Well, I could crop with a fixed aspect ratio (which is 16:9) and then export with a resize to 1920x1080, which would give me this:
Of course I can crop a smaller portion of the image, and then on export resize down to 1920x1080.
But what about cropping to exactly 1920x1080 at a true 1:1 pixel crop (without resizing down)?
So to crop this image...
... and end up with this....
... I would need to "guess" at the size, release the mouse and check (with informaion overlay turned on). Then do it again. And again. And again.....until I got it exactly at 1920x1080. That's a royal pain in the rear.
In Photoshop I can use the Marquee tool and define exactly 1920px x 1080px and then go to Image > Crop:
But in LR there is NO way to define actual pixels. Seems like it would be fairly easy to do, since you can already enter in a custom aspect ratio. Just add something like a little checkbox in the custom aspect ratio box. Something like this:
Or make it a set of radio buttons with the ability to choose between aspect ratio and actual pixels. (And rename the setting to "Custom Dimmensions" instead of "Custom Aspect Ratio".
JimHess raised an interesting issue (emphasis added):
In Lightroom, photo dimensions is part of the export function, not the editing. You cannot specify a size in the develop module. You are going to have to modify your workflow. Crop to the 2:3 aspect ratio, and then export with the long side set to 2400 pixels. That's the way it works. Otherwise, you would have to have a separate image for every purpose. The whole idea (for me, at least) is to have one master image that I can use for any purpose. Then I use the export function to customize the copy for whatever purpose I need.
Is this true? Doesn't seem to make any sense to me. Here is some sample crop metadata that LR saves:
   crs:CropTop="0.232327"
   crs:CropLeft="0.587547"
   crs:CropBottom="0.541667"
   crs:CropRight="1"
   crs:CropAngle="0"
   crs:CropConstrainToWarp="0"
So LR is saving information about 3 corners (don't really need the 4th). That's it. So it should absolutely be doable to define a specific number of pixels to crop to instead of an aspect ratio. The software will still write the same resulting metadata - the location of each of the three corners.
So then, why not just do what other people suggest? Why crop to whatever portion of the image I want and then resize to 1920x1080 on export?
Well, as Jim said, the whole idea behind LR is to have a single master image that I can use in a whole bunch of ways. So I can make virtual copies to do other kinds of crops. But exporting? That actually means I'm creating "a separate image" for the purpose of doing a timelapse.
See, as it stands right now, I can make all my changes in LR, and then import the RAW files into After Effects, and AE will read the metadata from the file and apply it. So if I get my crop right in LR (set exactly to 1920x1080) then I can simply import the RAW files and AE will see the footage at the right size. No need to render before importing, and no scaling needed, which improves the render time. I don't need to create a whole new set of exported images that eat up storage space. And I can easily go back in and make an adjustment to my crop in LR, then switch over to AE and reload the sequence. It'll instantly update, with no need to re-export from LR.
See, THAT's the power of LR. Exporting is great when you're at the END of your workflow, and for me, LR is just the first step in a long post production workflow.
Edit: Of course sometimes I don't need 1:1 pixel crops; sometimes I'll want to resize. In these cases I'll set my crop using a set aspect ratio and then deal with the resizing in After Effects, avoiding the need to render twice (because I still don't need to export from LR to use the RAW files in AE).

Lightroom won't export my exact dimensions

Lightroom won't export my exact dimension for my photos. How can I change this.

Are you running the latest version?
In Lr5.4 most but not all of such bugs are fixed.
If already running Lr5.4 then go to feedback forum and cast vote to the problem fixed.
Lightroom 5: export isn't resizing exactly to specified long edge.

Blurb book, exact dimensions 30 x 30 cm?

Dear experts,
I want to create and publish a Blurb book with Lightroom 4.3. I decided to use the 30x30 cm format. I created every page by my own design. Every page is one JPG-file (300 dpi), with pictures and texts. Which must be the exact dimensions of my JPG-files, so that I can put it 1:1 on a free, empty page in Blurb plugin in Lightroom? Thank you for every information!
Kind rgeards, Korjakski

I disagree that this is a Blurb limitation. As long as you work within blurbs specifiation they would not mind if I rotate an image, add a border or make sure that the frame dimensions actually meet my image dimensions as 3:2 or 4:3.
Of course I use other print-on-demand companies, but then the Book module is useless.
The best I can do is to set up a publishing service to my hard drive to issue the jpgs which I can enter into their proprietary book creation softwares. If I decide I need another development tweak, it is republishing. No means to get metadata like titles and captions across from my catalog.
The book module could have been specified in a very smart way, linking with the print module for template creation and refreshing this module at the same time, but it wasn't. Adobe's choice.
One that will be rectified, I hope, in LR5.

Crop - Front image dimensions

Hi,
I have a little problem with the cropping tool in the new CS6 version.
In CS5 I had the oppotunity to choose "Front image" and the crop tool would copy the dimensions from the chosen image.
Now I made a mistake and cropped a picture with the wrong dimensions. Ususally I choose "original ratio", but this time I forgot. Then normally in CS5 I just choose one of the other pictures in my workspace (with the original dimensions) and hit the "front image" button, and then I got back the the picture I cropped in the wrong dimenions, and now I could easily crop it with the right dimensions.
I found another discussion in the forum that answered exactly this question, and it said "Try pressing 'R' in crop mode. It will open Crop Image Size & Resolution window, where you can choose Source: Custom, Front Image, etc."
But when I press "R" in the crop mode nothing like that comes up. Instead the oppotunity to rotate comes up... :-( Not what I was looking for...
What to do?
I work on a PC
Best regards
Hanne

No, that was apperently the issue, thanks.
But it was actually a little easier in CS5. Because now I have to chose a picture in the workspace with the wanted dimesion, drag an area, save a preset and then I ca go to the other image I wanted to crop, choose the preset an then crop. In CS5 there was a direct button, and I could switch between higth and length, so that the hight dimensions became the length dimensions and so on, a good little feature when working with images in both horizontal and vertical versions.
But well, I gues I'll have to live with that.
Thank u.
Best regards Hanne

Exact dimensions of photo - how?

Small scale - large problem
I need a photo for my passport. The dimensions must be 3,5 x 4,5 cm. How do I create that as a file I can upload to the authorities? I tried export - but coulndn't find a way. (Also, the face must be 3-3,6 cm high,but I don't expect there is a way to mesure that in LR?)

As you are aware, the State Dept. has very exacting rules about photos they will accept for passports:
http://travel.state.gov/passport/get/get_874.html
Passport photo stores may not be measuring, and I don't know the State Dept. strictly applies those rules in every case, but they have absolutely been known to bounce photos back to an applicant and demanded retakes, and they've gotten stricter about their rules in recent years.
So as to your second question, yes, you can check your measurements in LR. It's a little kludgier than many other photo editing software programs for this kind of thing, because you may have to bounce back and forth between Print module (where you can display Rulers) and Develop module (where you can re-crop the image), but it can be done.
Display your candidate photo in any module of LR so that it's the only photo in the big window. Click on Print Module. Do you see rulers around the sides of the frame the image is displayed in? If yes, zoom in and take a look and check the measurements doing some basic subtraction, and go back to Develop module and re-crop if needed. If you're cropping, keep the Aspect unlocked (click on the little padlock, upper right in Crop tool, if it's locked, to unlock it) so you can change the dimensions of the image without also making your face wider or narrower than it really is.
If you can't see rulers around the side of the image in Print module, in Print, scroll down the column on the right until you see Guides. Open Guides if needed by clicking on the little arrow next to it. The box for Rulers should be checked. Now you should be able to see the rulers around your image.

Custom cropping using pixel dimension

The banner image module for my website requires images cropped to 940 x 400 pixels. When I use the Custom cropping function in PSE 12 (on a Mac OSX 10.9.2), it only shows a cm dimension. Can I do a custom crop using a pixel dimension?

You should just be able to type 940 px and 400 px in the width and height fields
Another way is to use the Rectangular Marquee Tool and use Aspect>Fixed Size then enter 940 px X 400 px

Cropping to fractional dimensions

I'm trying to print 1x1.3 photos but custom cropping won't let me enter fractional dimensions. I read a posted message about entering it as a ratio (http://discussions.apple.com/thread.jspa?threadID=1400995&tstart=224), such as 10x13. My question is, if I do that, how do I get back to inches and not ratios? After all, a 10x13 ratio could result in a 1x1.3 photo or a 2x2.6 photo.

Welcome to the Apple Discussions. It's all in the size ratio. If you select a ratio that will print your 1 x 1.3 it will also print a 2 x 2.6 but at half the resolution. So when you go to print, you have to set the print size.
In iPhoto you will then have to set the print size in the Custom menu of the Print window.

TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

Image Not Exact Dimensions on Monitor

Originally noticed individuals faces were just slightly elongated on the monitor screen.
Used printer profile template and did not zoom to where you had to scroll up or down, etc. Although smaller than actual size, the entire image fit on the screen. Measured width and height and then calculated to see how far off the image ratio actually was. It was indeed slightly elongated.
Did this on two 17" monitors with different dimensions (Length & Width)and different monitor resolutions. Did this with both Windows XP and Mac Book Pro using the same image in Photoshop CS2 (Win) and CS3 (Mac). The Windows image is slightly more elongated than the Mac. The Mac screen resolution is slightly greater than the Windows. The image on the Mac is less elongated than that of the Windows but nonetheless elongated.
Never noticed until the recent purchase of the Mac.
The XP system prints exactly to scale. Have not yet printed with the Mac.
Any comments, suggestions?

Elongation on a monitor is only caused by a resolution setting that isn't appropriate for the screen proportions, or by an incorrect pixel aspect ratio setting in Photoshop. As the others say, an LCD monitor is best set to its native resolution.
If you're trying to get an image to display at exactly the same size it will print, that has nothing to do whether you're using a Mac or a PC. Both platforms let you change the display resolution setting for any monitor, and that changes how large an image appears on screen when you view it at, say, 100%.
If you want an image to display at the same size it will print, first you need to enter the pixels per inch of your monitor into the Screen Resolution option in the Units and Rulers preference in Photoshop. For example, if your monitor is 14 inches wide and you set it to display 1440 pixels wide, then that's about 103 pixels per inch. Once you enter that ppi value into Screen Resolution, you can choose View > Print Size in Photoshop and the image will display at the same size it will print. Entering the correct Screen Resolution will also cause the rulers in Photoshop to match up with a real ruler that you hold up to the screen.

How to crop on exact scale

I have series of jpg files. These jpg pictures are taken from a camera mounted on a firm stand and so there all the picts are taken exactly at the same spot.
Now I need to crop from each of the pictures, the same portion. In this regard the all the pictures are required to be cropeed exactly on the same place. Can anyone help me to solve this problem.
Thanks in advance

TLL,
I've found the script works fine with various image modes and file formats including jpg. Since the OP is using CS3, OpenGL should not be a problem.
My best guess, not knowing anything about the image content is that auto align should be turned off - that can hang if the images are poor candidates for alignment. System resources might be an issue or permissions accessing the files. It has been a long time since I've used CS3, but I seem to remember an early issue with the script and that is why I mentioned the updated version.
I did not previously mention it, but there is another advantage in using this approach. Since the OP is interested in doing measurements the cropped stack is available for running any of the statistics routines in the extended version and for showing exactly where in the images content has changed with time.

Export illustrator file to exact dimensions

I have an illustrator document with the art-board size at 1000x1000 px and I need it to be exactly that but when I export as a png, it exports at ~ 4000x4000 px, even if I tick "use art-boards." What is the problem and how do I fix it?
I am using illustrator CC.

is it 4166 px?
it's because you're exporting at 300 dpi. make it 72.

Printing with exact dimensions

I love being able to use the inspector to set the exact width and placement of objects on the slide. My problem is that when it prints it is never exact. I have made sure my scale is set to 100%, but no joy. I have removed the borders, but no joy. Please tell me Keynote was not designed to let you specify an 11.8 cm circle and then have it just print a 12 cm instead?
Thanks,
Tom

You'd be hard-pressed to even get an expensive CAD program to perform this feat -- and no matter how carefully the artwork is done, it still has to be processed by a printer driver before it is ultimately sent to some consumer-grade printer. Send the same file to a different printer and you will likely measure yet a third circle size.

Helix - Exact dimensions of screen+bezel and cutout locations for custom screen protector?

Hey Helix owners,
I want to get a screen protector for the Helix, but I don't want the anti-glare one offered by 3M. Photodon prints custom screen protects to dimensions you give them. I was hoping to get the dimensions of the screen+bezel and the cutout locations for camera and tablet button... I'm not able to measure these very precisely myself. Anyone know where this information can be obtained?
I called 3M and they sent me a data sheet for their anti-glare protector, but it contained no info on dimensions and cutout locations.

Hi,
I'm from germany so no 'best buy' but I think I will lock around sleeve/bag for a different product with same measures. Any tip?
The clear plastic case is not what I want. I would like to use the player without such protections. I just want a sleeve to protect the player while its in my jacket/pants.
Btw, i have bought this version: Creative Zen (maybe european version?). I also doesn't seem to have your mentioned sleeve. I also couldn't find it on the website.
Anyway, thank you,
Chris

Cannot crop to an exact pixel dimensions

I am having a hard time cropping to an exact pixel dimensions upon export. For my work, I need to crop to exactly 2166X1600, with a tolerance of no more than one pixel off of those dimensions, i.e. 2166X1599.
I set crop tool to 2166X1600 and crop all of my images. On the export I constrain to largest dimension of 2166 in both horizontal and vertical directions. Results vary widely from right on 2166X1600 to several pixels off on the short side. Sometimes more than 1600, and sometimes less. Any thoughts as to why these constraints do not work exactly? Some sets of images I have to redo as many as 25% of a gallery of 200-300 images. Any thoughts? Thanks!

See, I don't need to crop the original image to 2166X1600. I need a finished image at 2166X1600. Meaning, in theory I should be able to crop an image to 1:1.35375 ratio, which is 2166X1600, and export to constrain to 2166 on the longest side. When it's constrained to 2166, the short side should always be 1600.
Here's where the problem is... When you set the crop window to 2166X1600, you expect that when you size your crop on your image that the only options for the boundary are multiples of 2166X1600. In reality, the crop visual boundaries are approximate. Here's an example...
I have an image that I have cropped to a finished size of 3185X2350. Which is based upon a 2166X1600 crop. When I export it, I need the 3185 to become 2166. So the long side is constrained to 2166, and it is reduced by a factor of 1.47. 3185/2166=1.47 If I reduce the short side, 2350, by that same factor of 1.47 you end up with a short side of 1598. Which is why I have a problem.
My invalid assumption was that when you set specific pixel dimensions in the crop tool, that only those values would be shown in the crop tool's bounding box. Photoshop can do it...

Crop Video Dimensions

Hi. I am using Premiere Elements 8. I am wanting to crop the actual dimensions of a video I am working on...the video is of someone talking and is quiet narrow. I would like to be able to crop the video so all the extra on the sides is completely gone. I am putting this on my company's website and have a limited space where the video can go. I tried the crop tool but it just crops the video itself down, not the actual size that exports or the frame. Can this be done? Thanks.

Leslie,
I was hoping that you were going for FLV. While PrE does not let you Crop, you can alter the Aspect Ratio. In PrPro, you can Crop with FLV Export.
However, with FLV, you can Export to the vertical dimension that you need, and then Import that into a Project in Flash, with the Stage set to the dimensions that you need. You can then package and Export your SWF to the vertical Stage that you require. I have done this in Adobe Flash, and would also assume that some of the Moyea Flash editing applications (maybe others too?) can work with odd-sized Stages.
I've done "Sprites," which are often people walking and standing, with Transparency and Cropped to a strong vertical Aspect Ratio. These have been embedded in Web pages by the designers. Cannot tell you the exact steps that they used, but would assume just the SWF files.
Good luck,
Hunt
