Cropping a JPEG image without re-compression?
Using Photoshop CS6, is it possible to crop a JPG image without recompresing it when I save it?
Thanks
-g
There are some (non-Adobe) apps which will do lossless cropping of JPEGs, such as GraphicConverter and JPEGCrops.

Firefox 3.6.8 causing all JPEG images to be compressed like AOL 9.0
System Setup:
Windows 7 Home Premium x64
NVIDIA GeForce 9500 GT (newest drivers installed)
Aero is running, switched it off to troubleshoot. Problem persisted.
Steps to Create the Problem:
1.) Updated to 3.6.8 from 3.5.11.
2.) Loaded up my website: http://www.columbuswebseo.com
3.) I noticed that the background image looks compressed (where it has a gradient around the blurred light specks in top right corner) . Like a highly compressed JPEG image from AOL days (to speed up page load times).
4.) Messed with all FireFox, Windows 7, NVIDIA, physical Dell LCD monitor color settings. Even did research on my RoadRunner connection to see if they implemented an accelerator of some sort. Disabled Add-ons one by one re-testing the issue along the way. Problem persisted.It's not your graphics card. It's not your OS. It's not your browser.
It's your internet. I had a broadband card, and I figured out that my ISP (Internet Service Provider) was actually downgrading my image quality to make my internet faster. It's called Network Optimization. Look in the options menu of your broadband connection application (Like if you have T-Mobile or whatever, look in the part the application that connects you to the internet) and see if you can change your Optimization Settings. This should clear things up for you.
Also, if your internet is really that slow, like mine was, I would suggest getting another provider. It's the best option. Hope that helps. :) -
In Aperture under INFO at bottom it says Badges; if it has an Icon in the block it compresses JPEG image down to KB? Using mail, using drop box with my Aperture and can't figure out how to get rid of 'Badges with the Icon in the box to be able to send full size. Also have been using: "onOne Software" an add on editing program thats awesome, works as a stand alone, Aperture, & Lightroom.
Bottom Line I can't send to lab my web page, or individule without it compressing. Even created a desk top folder droped & dragged in ZIP & still Compression?See this link: Aperture 3 User Manual: Understanding Badge Overlays
The badges in the Info panel have nothing to do with compression. The tell you, if your image has keywords attached, if it is a raw or jpeg image, if has been externally edited, or if it is referenced.
When you send an jpeg using mail, you need to set the image size in Mail to "Acual Size", otherwise will Mail compress the image. For example:
If you have really large images, Mail may not be optimal, because the server of the recepient may refuse to accept large Mail attachments. In that case export the image from Aperture in the resolution you want with "File > Export" and compress it as a zip file. That will not reduce the quality.
Send the zipped file, if it is small enough, otherwise upload it to an ftp-server.
The receiver can uncompress it.

How can I resize an image without losing resolution or using the crop tool? I am using Photoshop Elements 13 on a PC.
Hi Peru Bob,
I've tried two images, the results were:
Image 1
Jpg, original file size 923KB, dimensions 848px x 279px.
After resizing to 848px x 180px with 72dpi, the file size decreased to 164KB.
Image 2
Jpg, original file size 809KB, dimensions 1200px x 1800px.
After resizing to 668px x 722px with 72dpi, the file size decreased to 307KB.
So, there seems to be a fair file size loss - is this to be expected? -
Hi,
I am not too familiar with images technology but I read that jpeg is alrady a compressed file. Will there be any space gain if I save jpeg image in BLOB or CLOB column and compress?
Regards,
AsimIf you can save a JPEG in a CLOB you are a far better developer than I. <g>
There may be some compression though likely not much. What I would suggest is that in 10g or below you look at UTL_COMPRESS
http://www.psoug.org/reference/utl_compress.html
and in 11g, additionally, you look at SECURE FILES and DEDUPLICATION

How can I attach an image without the image is in the email body? (using the new mail the Lion)
How can I attach an image without the image is in the email body? (using the new mail the Lion)
I want in attachment, not in the body mail.I think your only solution is to zip the image files first and then attach them.
Read this from a site I found:
Sending Graphical Attachments -- When you attach a graphical image to your message, the recipient of your message sees the image inline (that is, in the body of the message) if her email client supports inline display. ("Take Control of Email with Apple Mail" contains a table listing the capabilities of popular Mac and PC email clients.) If a client does not support inline display (or the recipient has turned off the inline display option), the file appears as an attachment that must be opened in a separate program.
On the one hand, an inline image is easier for the recipient to see - all she has to do is look at it. On the other hand, inline images can be frustrating to scroll through. If you do not wish to send a graphical image inline, you must compress the file before attaching it - Mail, sadly, lacks a built-in compression option, though fortunately for Panther users, the Finder offers Zip compression without requiring a separate application.
Note that when you compose a new message, Mail always shows attachments in the body of your message. You can manually drag them somewhere else, but many email clients display all attachments in a separate list, regardless of where you place them in the message body.
If you paste an image into a message or drag & drop an image from another window (say, a Web browser), Mail converts the raw image data to an attachment in TIFF format. On the other hand, if you drag & drop the icon of an image file (or use the Attach button to locate the file using the file browser), Mail leaves the attached image in its original format. This difference is significant, because although most email clients can display JPEG images just fine, support for TIFF - especially in non-Mac email clients - is less common. If possible, I suggest attaching image files as opposed to pasting or dragging in raw image data. -
How to crop photos on iPhone without reducing quality?
I've discovered that the crop function in the standard Photos app reduces the resolution of the remaining portion of the photo (beyond what you would expect after removing part of the image). The Photos app seems to re-encode the image at a lower image quality than the Camera app achieved when it originally took the photo.
For example, if a I take a photo with the Camera at 2448x3264 (3.4MB), and crop all four edges a little in Photo, it reduces to 1536x2047 (992K). If I load the uncropped image into Preview on my Macbook, and do the same crop (as close as I can - and I tried to get it very close indeed) - the image is 2107x2860 (2.1MB). Furthermore, when I look at all three images - uncropped, iPhone-cropped and Preview-cropped - at "Actual size" in Preview, it's clear that the iPhone-cropped image has been reduced (ie. it appears "zoomed out", or smaller dpi) compared to either the uncropped or Preview-cropped images.
Does anyone know if there's a way to crop images on the iPhone without reducing the image quality in this way?Thank you for the quick reply.
Yes, I understand that a crop function should just remove parts of the image without changing the resolution of what remains. But that's not what I see on the iPhone.
Let's say I have a photo taken on the iPhone which is 2000x3000, and there's a VW van in the photo which is roughtly 500x500 pixels in dimension. If I crop the photo to only include the van, I'd expect to have a 500x500 image. And indeed, that's what I see when I crop the photo in Preview on my Macbook.
When I perform the same crop in Photo on the iPhone, however, I get an image of the van which is smaller - only about 375x375 pixels. It's exactly the same part of the photo, but the iPhone seems to reduce the resolution of the remaining image, not just remove the parts that were cropped.
I'm looking for a way to crop an image on the iPhone without reducing the resolution of what remains. Anyone know of an app that can do that? -
Help with managing RAW and jpeg images and installing iphoto 9
Greetings: Fist, let me make the neophyte apology and plea - I'm sorry, I should have come here first; I didn't and now I need your help.
I have just purchased a macbook pro (still in its box) with updated software for my older imac os x. I have a number of Canon related photo editing programs (that came with my 40D digital SLR) and Adobe photo elements 6 for mac on the imac. Following some erroneous advice I have made a complete mess of the pictures folder's content by trying to delete images directly from that folder (there are now 6000+ images in the folder, many of which are duplicates(?). Most of the images are not tagged or labeled and some have been organized in/by iphoto (I corrupted the iphoto's library structure very early on by disrupting and editing its images - which might explain why iphoto had a difficult time 'finding' and displaying some of my photos). The picture folder now holds jpegs, smallRAW images (a Canon 40D photo format) and various duplicates of the orignal images - (some of the duplicates don't display as images, but as jpeg logos, which, when opened contain duplicate image or are completely black) The first time I downloaded RAW images into iphoto 6 the RAW data displayed as a black image. When shooting in smallRAW on the Canon 40D, the camera produces a jpeg image for 'easy viewing and editing in the camera' but it looks as though iphoto 6 made duplicates of the jpeg and the RAW data and stored them in different locals in the picture file. In an attempt to get the number of images down, I have been trying to delete them from the picture folder. (My daughters both download images rather indiscriminately in hopes of 'editing them on the computer' which inevitably does not happen) and there is a lot of experimental bracketing of images - shooting raw and different Camera formats etc., all of which need to be cleaned up before I proceed.
Sometime in the not-too-distant future I would like to have iphoto 9 running on my imac with a clean library of images and a seamless way of downloading, editing and storing images (including the RAW data).
The macbook pro is for my highschool-aged daughter, who will run iphoto 9 but not have any RAW image data on her system. She would like to copy some of the old iMac's images to put into her own iPhoto 9 library (probably using a disk, email or on-line photo service - ideally, I would like to be able to copy and remove a number of those images from my HD and give them to her for the macbook)
A few questions and queries: Can I 'dis-able' iphoto 6, while I delete images (RAW and jpeg) from the picture file? (and is this even a good idea).
Once I have edited the # of images down to a reasonable size, should I re-launch iphoto 6, rebuild the iphoto library and then update to iphoto 9 or skip v6 and rebuild with v9?
And now for the 'how stupid is this guy question' - I really had planned to purchase an external backup; but between new the macbook, car repairs and braces it has never come to fruition. So, I have never properly backed up my images. What is the bare-bones, least expensive method for me to do this? I'd even consider burning everything to disks if that works. I can't afford the $ to purchase a new external hard drive right now (really). Budget is set aside mid-November for one though.
I've been looking through some other discussion boards and it looks like I'm not the only one having RAW image issues. I know that shooting smallRAW with the companion jpeg is probably not helping things but I take my camera equipment on extended canoe trips - and we like the ease of on-the-spot editing with this format.
Thanks in advance for your help - MarkTerence, Is the picture folder the primary source for the images or does that data reside somewhere else?
If you gathered them there, then yes.
I really don't want to have to go through 14,000 images looking for the pictures that I want to keep (or is that my only option?).
Only you can decide what you want to keep.
Why does the computer keep making copies of the images and filing them under date and events?
That's how iPhoto works. It's not a problem usually, only you did go in there and make a problem, and now we are trying to fix it.
You advise not to muck around in the picture file via preview,
No I don't. I advise not to much around in the iPhoto Library Folder.
but if I download images through a program other than iPhotos - image capture or adobe aren't I doing that anyway?
Adobe what? Adobe is a software manufacturer who make many excellent applications, you need to be more precise. And no, if you import photos with Image Capture or “adobe” no you are not interfering with the iPhoto Library Folder.
Can you edit a base image file somewhere and remove it from the HD without iphoto making a copy of it and storing it somewhere else?
This is stunningly easy. Don't use iPhoto. Use an image editor.
I want to look the negatives, decide which ones I want and throw the rest away. Can that be done or am I way off course?
Yes, and iPhoto (or similar apps) make this really easy.
Hook up your camera. Import the pics to iPhoto. Go through the imported pics. Trash the ones you don't want. Then process the ones you do. But you must learn how to use iPhoto to do this successfully
To trash: put the pic in the iPhoto trash and empty it. This removes the file from iPhoto and the Hard Disk.
Process it: If you want to use another editor: You can set Photoshop (or any image editor) as an external editor in iPhoto. (Preferences -> General -> Edit Photo: Choose from the Drop Down Menu.) This way, when you double click a pic to edit in iPhoto it will open automatically in Photoshop or your Image Editor, and when you save it it's sent back to iPhoto automatically. This is the only way that edits made in another application will be displayed in iPhoto.

How do I copy and paste images without a reduction in size?
I am working on a project where I want to include several jpeg images that are saved on my computer onto a new single 8.5x11 page in Photoshop. Even though the percentages are the same on both the images and the Photoshop page, when I copy and paste the images onto the page, the size of the images are greatly reduced (from 5" to 1".) I would greatly appreciate instruction on how to copy images and paste them on to a Photoshop page without the reduction in image size. I have accomplished this task previously and I had no problem. Is there a setting that I am unaware of that I need to change in order to proceed with the project as planned? Thank you for your time.
You are a genius! That's it. Thank you so much for taking the time to help...

How to get crisp jpeg images for slideshow on a Mac with Final Cut?
Hi, I imported a large number of jpegs into Final Cut Pro and when I export to Quicktime Movie (not modifying the sequence size or settings I notice the quality of the jpeg images looks rather washed out and a bit fuzzy. The image dimensions of the jpegs are actually 2848 x 4272 and I was originally using a sequence setting of 720 by 480 (which scaled the images to about 12%). I experimented with doubling the sequence setting to 1440 by 960 and scaled the images to about 25.5% - still a bit washed out look.
Basically this will be a presentation on a computer and output via projection. Looking for best possible and clearest photos. I experimented with iPhoto and when you play a slideshow it looks very crisp - this is what I am aiming for. When I export using the Slideshow export at the largest size 640 by 480 in iPhoto to quicktime - the quality seriously deteriorates.
What would be the best way to maintain the crispness of the photos in Final Cut for an export to Quicktime that would be show on a Mac via a projector? Thank youHi Nick, I do see information on creating a slideshow with Quicktime at: http://www.apple.com/quicktime/tutorials/slideshow.html
however it appears Quicktime X removed that capability. There is no 'open image sequence' option from the File menu in Quicktime X.
If I do end up sticking with Final Cut - would you recommend any codec and/or dimension size that would result in the best quality or the most crisp image? I also need a few fade in's and out's on various parts - I don't believe I would have the control without Final Cut.
Would resizing the image files in Photoshop to 1920 pixels by 1280 before importing them into Final Cut result in crisper images? Thanks. -
How do I change the JPEG image size in PSE-12 when opening from RAW
Switching from PSE-9 to PSE-12. When a JPEG image is opened RAW in PSE-12 the size is 18.72" Wide x 12.48" high 300 DPI. The same image in PSE-9 is 23.4" wide x 15.6" High 240 DPI. How do I get PSE-12 to open the image as in PSE-9?
Uncheck the boxes at the bottom of the dialog Scale styles and resample Image so that only constrain proportions is checked. If you the change the resolution box from 240 to 300 you will get back to your original dimensions.
This is a meaningless thing to do, you still have the exact same number of pixels, you have only changed the metadata number in the file for ppi, and your prints are not affected by this number.
You could also use the same method to change the dimensions to 6 x 4 or 9 x 6 etc.
There are some cases (actually most cases) where you need to CROP the photo to change the dimensions, when the aspect ratio of the original photos is different than the aspect ratio of the final photo; the specific case in 99jon's example is the only case you ever want to change dimensions using Image->Resize->Image Size, where the aspect ratio doesn't change from 6x4 to 9x6 (or 12x8 or 18x12 or ...), and even then, you could do the same thing simply by telling the printer the size you want, you don't really need to do anything in PSE. -
How do I control the quality of JPEG images?
I've written a program that scales a set of JPEG images down to various dimensions. I'm happy with the speed of execution, but quality of the images could be better. How do I specify the quality of the JPEG images I create? In graphics editors, I'm given the option of controlling the lossy-ness (?) of JPEGs when I save them, either reducing image qualify to shrink the file size or vice versa. How can I do this programmatically?
ThanksHi Jhm,
leaving aside the scaling algorithm, to save an arbitrary image with 100% quality you'd use
something like the following code snipet below
regards,
Owen
// Imports
import java.awt.image.*;
import com.sun.image.codec.jpeg.*;
public boolean saveJPEG ( Image yourImage, String filename )
boolean saved = false;
BufferedImage bi = new BufferedImage ( yourImage.getWidth(null),
yourImage.getHeight(null),
BufferedImage.TYPE_INT_RGB );
Graphics2D g2 = bi.createGraphics();
g2.drawImage ( yourImage, null, null );
FileOutputStream out = null;
try
out = new FileOutputStream ( filename );
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder ( out );
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam ( bi );
param.setQuality ( 1.0f, false ); // 100% high quality setting, no compression
encoder.setJPEGEncodeParam ( param );
encoder.encode ( bi );
out.close();
saved = true;
catch ( Exception ex )
System.out.println ("Error saving JPEG : " + ex.getMessage() );
return ( saved );

How to make Photoshop save Aperture imported JPEG images as JPEGs
Recently, I upgraded from Photoshop CS 5 to CS 5.1.
My point and shoot cameras record in JPEG format. Often, I'll import those photos into Aperture and then tweak them in Photoshop using the Edit in External Editor command. My preferences for the external editor in Aperture were set to 8-bit, Photoshop
With Photoshop CS 5, I would edit the photo and choose Save and the edited photo would be saved back to Aperture as a new version, in a JPEG format.
Now, using Photoshop CS 5.1, when the imported image from Aperture is converted into a PSD file and when I save back to Aperture, I end up with a PSD file.
How can I revert to how it was before? JPEG image in Aperture, opened in external editor Photoshop as a JPEG, edited in Photoshop, then saved back to Aperture as a new version JPEG?
(Though this question is approached in this forum, a solution to my question is never found as each dicussion ends up going off-topic from the original question)clapperincus wrote:
Any further ideas from anyone who's experienced trying to open a JPEG from Aperture in Photoshop as a JPEG?
Like I said before, you cannot open a jpeg as a jpeg, the file must be decompressed to open in PS or in Aperture, and that has always been the case.
I do not know how it used to work, but I tested and you are correct that with PS 12.1 and with Aperture 3.2.2 a JPEG sent to open in external editor (PS) is opened into your choice of lossless format and then goes back to Aperture in the lossless format you chose.
IMO this is the way it should be, because every save into JPEG loses image data, so such saves should be limited to the final export, in this case when the image actually leaves Aperture. If the file was compressed as a JPEG when leaving PS, decompressed and edited in Aperture, then compressed again to export as JPEG from Aperture, unnecessary additional image data loss would occur.
It is always better to save the application of lossy compression until the very last step in a workflow because other usages (printing, for instance) may occur before applying the lossy compression.

Most efficient way to do multiple crops on many images?
I have a large number of images shot in the default 4:3 aspect ratio. I need to print almost 200 as 4x6, and and undetermined but certainly large number as 8x10, so I have a lot of cropping to do. What would seasoned Aperture users suggest as the most efficient way to do this? I've thought of two possibilities:
1. Duplicate every image I need to print in both sizes and crop one for each size print. This is the best option I've thought of, but it would certainly eat a lot of drive space.
2. Do all the 8x10 crops, revert to original, and do the 4x6 crops. Saves disk space, but leave me with only the 4x6 crop in Aperture. (Sounds like I want to have my cake and eat it too, I suppose.)
Anyway, there are a lot of you out there who have logged a lot more Aperture hours than I have. Is there a better workflow I have not considered?
Thanks,
BenHello Ben,
the beauty of Aperture is, that you can have many versions of an image without needing much extra disk space.
To have three versions of an image cropped to different aspect ratios, don't create duplicate master images but use (from the Aperture main menu) "Photos -> Duplicate version" or "New Version from Master". Then crop this new version to a different aspect ratio. Aperture will not really render a new image file but just store the cropping rectangle to be able to create the cropped image when you export or print it.
So you can have an original version, a 8x10 version, a 4x6 version in your library without needing much extra space - that is one of the rare occasions when you can have your cake and eat it too
