Cropping while maintaining pixel size

Just got LR5 - wish it was as intuitive as PSE. A few initial questions:
1) When I crop in LR, I see no way to maintain the original pixel size as is easily done in PSE. Is it not possible?
2) When I select "Help" or press F1 in LR, I get LR Help, however the Search feature doesn't list LR as one of the Product selections in the dropdown box. I did register LR.
3) When you make an adjustment in LR, isn't there a way to Undo it? I thought you might be able to delete it from the history.
4) What is the best free source for learning LR, preferably video. I did see the ones by J. Kost on the Adobe TV website, but they weren't very detailed/complete.
Thanks.

Thanks dj. A couple of follow-ups on your responses then I'll mark it as correct:
1) So when I crop in PSE with the pixel size set at the size of the original, that is not really buying anything? I don't think it does a resample, just decreases the Document Size by a corresponding amount. There is no advantage as far as photo quality or anything else to keeping the pixel dimensions at the larger size (of the original)?
3) When you "undo" by double-clicking on the name of the slider, is this a true undo (i.e. the history item is deleted) or does it just create another history item that offsets the original adjustment?
And a couple of other items on recommended ways to do things:
- Would you recommend when making adjustments to show both the before and after in the panel to see how it is changed?
- Do you personally use shortcuts all the time? From watching videos from J. Kost and some other guy whose name I don't recall, they both seem obsessed, to the point that it is annoying, with using shortcut keys. There are so many of them that I don't see how it is a shortcut if you have to look them up.
Thanks dj.

How to maintain pixel size when exporting?

When exporting an edited image (ex: 20 MB) from Aperture to a desktop folder, I choose file>export>versions>jpeg original. When I open the exported image in the desktop folder (it opens in preview), the Tools/Inspector window says that the image is now only 2MB. This has not always happened. Can someone tell me what I might be doing or not doing that is causing this, or what settings I need to change?
Thank you.

golindy,
JPEG is a lossy format that relies on two ways of reducing the file size. The first is the lossy part that throws away data that is percieved to be unimportant for human vision, the resulting data is then further compressed losslessly using the same type of compression zip uses (this is why zipping a JPEG doesn't lead to further size reduction).
The more you throw away in the first part, the more likely the image is to suffer from 'compression artefacts'. The number you select on export determines how much data gets thrown away.
I don't know what '12' officially means for Apple, but from eyeballing files, it seems like it throws away pretty close to zero. So a file output with 12 is top quality.
Aperture has always worked the same way here, it hasn't changed during any update.
However, some things that may affect it are:
1) The effeciciency of the both compression algorithms seems to improve over time.
So a year ago, a 20 Mega Pixel image might compress down to a 5MB file using a quality setting of 10. Today that very same file may compress down to a 4MB file at quality 10. But it's important to note, the quality of the file will be the same, quality 10. All that has happened is the more efficient algorithm has allowed an extra 1MB of file space saving.
2) The raw converters periodically get improved with new rendering. One area that has continually improved in Apeture is noise supression and more natural sharpening.
These impact the first part of the compression process. A noisy image with harsh shapening will compress less than a clean image with more subtle sharpening. So better raw processing can also impact the exported size. Note, this one works in both directions, an improved conversion that resolves more details will output a larger file size, whereas an improved conversion that gives less noise will output a smaller file size.
So in your case, I think what was happening was you were not losing quality, just gaining file size efficiency, and now you have changed to quality 12, you are exploiting that file space saving by now outputting higher quality files.

Zooming in on a picture while maintaining frame size

Hi all,
I am hoping someone would be able to tell be how I could zoom in on a photo without it expanding to cover the other footage in a shot.
To better vizualize... imagine you have footage of an interview... the person speaking is on the left. I would like to place a picture on the right side of the screen and zoom in on the picture without also increasing the overall amount of space that picture takes up on the screen. I assume there must be some type of framing tool.
I am running Premiere Pro CS4 - full production suite. I also have CS4 Design Suite if that has the right tool.
Thanks for helping out a noobie!
Dan

Perhaps I need to be more clear, I want to do a gradual zoom. Not simply show the whole picture, then show a close up.
I mean, sure I could go into each frame and recrop the picture, but that would be ridiculous.
There must be an automated way of doing it. A way to set boundries for a picture, so that no matter how far you zoom in, the overall dimensions of the photo, visible over footage, does not change.

My crop tool in CS5 does not give the option to crop by pixel size

How do I get the crop tool to give me the option of cropping by specific pixel size. Nothing appears in the dropdown menu except standard crop sizes in inches.

Have you tried entering the numbers with the suffix "px" in the entry fields?

Creating an 11x17 booklet while maintaining file quality/size

I regularly use Pages for newsletter production - my newsletters must be in 11x17 format when submitted to a printer for production. I do not have InDesign or Quark - I'm trying to avoid the expense, quite honestly.
So: when I have completed a Pages document, I must convert to 11x17. I currently use Cocoa Booklet to do this. However, much to my dismay, I've found that the size/quality of my document takes a nose dive when I convert to 11x17 format with Cocoa Booklet!
I want to give my file to the printer in the highest possible resolution. One of the newsletters I do frequently contains artwork, and the creator deserves decent quality images in the final printed product.
So my question is: is there any way to create an 11x17 document from a Pages document while maintaining the original document quality?
Thank you!

See the other post for the problem of assembling an imposed set of pages. Usually though your commercial printer will handle this. If they can't I really wonder whether they should be handling the job.
The core problem of resolution and quality suitable for commercial printing is however a problem with the colorsync quartz filters used by OSX to produce PDF-X files. Apple has set these up wrong and made them well nigh impossible to correct.
If anyone out there can give detailed step by step instructions how to alter the filters in Colorsync Utility and make them appear correctly and consistently in the printer options, I and many others will be eternally grateful.
As it stands the output reduces many graphics, effects and even some text to an unacceptable 72dpi pixellation.
The inking is wildly over what commercial printing requires. Normally this should never total more than 320% to prevent smearing, pooling and overwetting and bubbling the paper.
The filters do not provide the crop marks, bleeds or printer's slugs needed for production.
The filters do not allow targeting of the individual printer's equipment and settings.
There is no transparency or documentation of the process nor its effects which makes it difficult to control or know if it is correct (as it stands it is not).
Danger, Danger Will Robinson! Do not use!
Not much else can be said until Apple corrects this and stops misleading its users into thinking they (Apple) are actually providing a solution. In reality they have created a massive problem.
I pray that someone has finally been listening and this gets fixed in Snow Leopard.

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.

Cropping images to exact pixel sizes

I'm a Photoshop user but being a recent Mac convert I'm having a go with the Aperture 2 trial.
I'm a bit confused about how to crop an image to an exact pixel size. I've watched the video tutorial several times over but I still can't achieve what I want. So ...
* My original image is 2816 x 2112
* I select a 4 x 3 aspect ratio using the Crop HUD
* I pull the rectangular box out to take in the section of the image I want to crop out of the original
* I want a finished image of 500 x 400 pixels
* I go to the Crop field in the Adjustments tab and change Width to 500 and the Height to 400
* The crop area on the image ends up as a small box in the bottom left hand corner and when I hit Return, all I end up with is that area of the image inside the box when what I want is the originally selected crop area but at 500 x 400 pixels
* If I stretch the rectangular box out to cover the original area, the pixel dimensions go up again beyond 500 x 400
Which part of the process am I missing?
Thanks for anyone's advice,
Mark

What you type in that box is just the ratio not the actual pixel number. And the box does not like to many digits in there. A ratio of 4 x 5 would work perfectly fine in your case, but more complicated ratios like 21 x 50 don't work.
To get 500 x 400 px you must then export your image with settings that restrict your image, eg, to fit into a 500 x 500 px box.
The idea behind this two-step approach is that you might think of 500 x 400 px output right now, but by doing the actual pixel generation at a later point, you can always easily export later at 1000 x 800 px if you need a higher resolution version with the same aspect ratio.

Aperture changing pixel size after using Retouch/Repair/Clone tool?

I apologize if this is a stupid question - I'm new to using Aperture and have a rudimentary knowledge (at best) about the mechanics of Aperture.
I use the retouch tool on a portion of my photo, and the pixel size is reduced. I want to maintain the original 12.0megapixels. How do I work with the photo without changing the pixel size - or, how can I restore the orginal pixel size after editing the photo?
I've also cropped the photo, constraining the aspect ratio at 4:5.
Here is the file info before I start working with it:
And after using the retouch, this happens:

Again this is not normal Aperture behavior, this doesn;t occur on my system. If you could post the screen shot of the adjustments it might help.
Sure - Here is a sample image. It is not a RAW file. It appears to be happening in every image in the library. I made a new library and it appears to be happening in the same pattern. I'm in Aperture, opened a photo which was imported directly into Aperture from camera.
Now, I'm going to crop to 4:5 ratio - from what I'm hearing, crop should not effect the 12.0 mp?
Notice how the MP is now 10.6?
Now, I'll apply auto enhance:
In this case, it looks like cropping does effect the pixel size. It's a different image from what I was using before.
Now, I use the retouch tool:
The MPs are now 9.7 - it keeps getting smaller and smaller!
When you crop, is it normal for the MPs to reduce?
Thanks so much for your help, I'm so frustrated.

Help reducing pixel size on i photo.

Hi
Desperate for help. I need to rezize to 675x550 to upload to a website. I do my crop and then export.I enter the above values and proceed. However when I check the photo info in the library the size is 675x450. This happens all the time.How can I acheive 675x550
Cheers Paul

Paul:
Welcome to the Apple Discussions. What you want to do is export the file to the desktop using the File->Export->File Export menu. In the export window select Format = JPEG and Size=Custom. There will be a sub window where you can put in the maximum pixel dimension for the photo and the other side will be resized accordingly while keeping the size ratio intact. Set the other options as needed and finish the export.

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.

How do I change the pixel size of my photos?

Hello,
Please give me step by step instructions on how to change the pixel size of my photos from the time I log in.
Thank you.

There are basically two ways.
Image>Image Size... This will adjust the quality of the image, allowing you to adjust the pixel dimensions and keep the full image.
In the tool bar on left side of screen 5th icon down looks like a sliding picture frame. That is the crop tool, that will adjust the pixel size of a document by removing a portion of the image, allowing you to get rid of portions of the image you do not want.
There are some other ways to accomplish the above, but these are the basics that everyone needs to know. I recommend playing with these tools on a copy of an image, that way you won't be afraid of destroying an image.

Is there a way to determine pixel size of type displayed in browser?

I'm still wrestling with getting type to line-break as I see it in Dreamweaver.
At 'Actual Size' in Safari, the type is bigger than I see it in Dreamweaver. I have determined that 12px is the appropriate size while working in Dreamweaver but when I view the text online it is much bigger and the line-breaks do not fall where the writer wants them to.
Here is the page in question:
http://www.kgngroup.net/logos_and_packaging.html
I guess I was wondering first, if there is a 'sizeometer' that can identify the actual pixels size of type as it is displayed, so I can tell how much bigger it actually is than what I am trying to build.
TIA,
Ken

Hi
The size of your text is set to 100% in your body elements css, this means that for Safari you will get a default font size of 16px, (providing you have not changed the browsers default settings).
Change the body element font-size to 12px in the css and see what happens.

I've run out of helpful stars to hand out to all of you nice people. Thank you so much, and as the post quoted here also demonstrates, there are 'overrides' in CSS. It struck me this morning as I have been thinking about this, the very first thing to introduction to CSS is that the meaning of Cascading Style Sheets is that there is an order of priority in command, and the troops closest to the front lines get the final say. I would think that the statement in the document would be the final word, but apparently it's the CSS sheet that takes priority in this case.
I think my thinking has been in reverse on this rule, not unusual for me, but now I need to re-educate myself thanks to this problem.

Exporting Versions to a specific pixel size

I want to export files for a slideshow that requires a pixel size of 1900 x 1200 , can it be done in Aperture ? , I have tried modifying the export preset , it does not work with (Fit Within ) is there another way ?
Thanks
Ray

Trythis,
What exactly is failing?
Your 1900x1200 size is a very strange size. That's not the 3:2 aspect ratio of an SLR or the 4:3 aspect ratio of point-and-shoot cameras. Also, Aperture will not enlarge pictures by choosing "fit within", since a smaller picture already "fits within". I.e., if you have a 640x480 picture, that already "fits within" 1900 pixels so Aperture will not make it bigger.
Also, Aperture will not crop your pictures on export. You may have to crop each picture first so that it has a 19:12 aspect ratio, and then "fit within" 1900 pixels. If the aspect ratio of a picture is 19:12 and the picture is larger than 1900 pixels, Aperture should properly reduce the size to 1900x1200, based on the aspect ratio.

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??

Automated process to crop away certain pixels

How can I automate the process to crop away certain pixels from the edges of a batch of pictures of different dimension?
Example:
Picture 1 : 400 x 600px
Picture 2 : 360 x 480px
Picture 3 : 600 x 800px
I want to crop away 5px from each edge of each picture which would then end up being 390x590px, 350x470px and 590x790px respectively.

MichaelTeoh wrote:

Picture 2 : 360 x 480px    = 36:48 = 6:8 = 3:4
Picture 3 : 600 x 800px   = 3:4
So you can record the three action to center crop your images to the 2:3 and 3:4 aspect ratios shown in your examples then use image size to size them you three example pixel sizes then use canvas size to to trim the 5 px of the border, just set the canvas to you three sizes 390x590px 350x470px and 590x790px do not check relative and leave the anchor point in the center. Five pixels will be trimmed form all sides. Any image that started with the correct 2:3 or 3:4 aspect ratios will not be cropped by the first crop only the canvas size crop will trim pixels.
To handle both Portrait and Landscape image the action would need to record a fit image step instead of the image size step a fit image step fit to longest side need to be recorded and the canvas size would need to be recorded to trim both width and height by a relative -10px.   My AspectRatioSelection plugin will automatically orient the aspect ratio recorded to the images orientation.

Sorting images by pixel size?

is there a way to sort images by pixel size (ie, all pis over 640x480)? i can't see any way in finder, vitaminSEE or iphoto to sort images this way. am i missing something? or could someone recommend a grogram that can do this (preferably freeware)? thx

zzwhitejd:
Welcome to the Apple Discussions. It may be how Picassa and windows handles thumbnails as opposed to OS X. When you imported directly from the PC you might have imported the support files that, on the Mac, contained in the Resource Fork of the file. If you can try copying some of the files again to a folder on the desktop first and see what you get in the way of the number of files.
To get rid of those duplicates already in the library you can try using Duplicate Annihilator or iPhoto Diet. In either case make a backup copy of the iPhoto LIbrary folder just in case the results are not what you expected.
Do you Twango?
