JPEG file options

How does saving a file as alow (vs high) format JPEG reduce the file size? I saved both as a test, opened in photoshop and looked at image size: the resolution and pixel dimensions are the same while the file size differs.

Changing jpeg compression from high to low never affects the number of actual pixels in the image, but it does affect how highly compressed the file is when saved and how many visible artifacts you might see. The change is going to be in the size of the file saved to disk. Check out those numbers and that's where you'll see the difference.

How do you save your artwork in Photoshop CC 2014 as an PNG or JPEG file when it doesn't give the option?

How do you save your artwork in Photoshop CC 2014 as an PNG or JPEG file when it doesn't give the option?
Thanks for your time and help in advance.

Thanks for replying. I actually got it to work. I had my work set to 32 Bits/Channel in stead of 16 or 8. Once I changed it to 16bit/Channel, it gave me the option to save as either file. Thanks again.

Is the JPEG compression option on TIF files lossy or lossless?

Is the JPEG compression option on TIF files lossy or lossless?

I accidentally used the JPEG compression on some important TIFF images. I usually use
no compression but didn't realise the option had been chosen. I can't easily re-scan. I have
read about lossless JPEG and with TIF considered a lossless format I had hoped this may
be the case.

JPEG file format option missing in PSE 9

The JPEG file format option in the "Save as" dialog is no longer listed in PhotoShop Elements 9. I've completely uninstalled and re-installed the software, but the JPEG file format option is not there.

Most likely you have a 16 bit file and JPEG is an 8 bit format. Go to image>mode>8 bits/channel and jpeg should reappear as an option.

Option to include personal-LR-keywords into DNG (or/and into jpeg) files ?

Is there an option, or a way to
include personal-LR-keywords into DNG (or/and into jpeg) files ?
Or, sorry, did not check it out.. : maybe it's allready automaticaly the case that a DNG (dng, by definition, also incorporates xmp, right?), when opened/imported in someone-elses computer/lightroom.. will positivaly respond to the creator's keywordings of that image?

The place option is usually not available for 16 bit files, so when editing images in acr
change where is says Depth to 8 Bits/Channel or after you open a 16 bit file, go to
Image>Mode>8 Bits/Channel.

How to view .jpeg files in Yosemite

Am using Yosemite (10.10.2) on my iMac and want to view rather old .jpeg photos. When I attempt to open them, I get an error message saying Photoshop 3.0 is required. When the file titles are displayed in Finder, I can see the little-bitty picture, so I think the Mac knows the picture is there, just reluctant to let me view it. (I tried using Preview and iPhoto and neither one works for this.)
Is there some way to view these photos with the existing Mac programs?
Thank you,
TBS2

Thanks for all the replies. I tried to respond to everyone individually, but the rules say I can only post content every 30 seconds. Hence this combined reply.
Don't have "Quick Look" on my iMac. I did use the "Get Info" option to open all .jpeg files with Preview. Didn't work. Did try to open the files from within Preview using the "Open file" option.
Tried opening with Firefox (thanks to whomever posted that hint somewhere on the blog) and the Firefox error message says there is an error in the file.
I am able to open other .jpeg files with Preview, so I am now of the belief there is a problem with the file, not with how my system is handling it.
Suppose a "fixer" of some kind is in order, but I don't know what that is!
Thanks again for everyones help.

Moved jpeg files to other folder, now iPhoto can't find them

I dragged/dropped some original jpeg files into a new folder to aggregate certain files together, but since they are now in a different folder iPhoto 9 can't find them. The thumbnails in iPhoto still remain, but results in the large black/grey "!" when I try to open them. I'd rather not rebuild the enormity of my entire photo library over this, so is there some other way to re-link thumbnails to files?
iTunes makes this easy with music. When I click on a file name and it can't find the file, it offers to allow me to locate the file myself, and then it re-establishes the link between the iTunes library item and the file. No problem.
How does one go about doing this in iPhoto for, say, a couple of dozen files without having to start over with an ENTIRE rebuild? I know exactly where the files are, and it seems ridiculous that iPhoto isn't equipped to track the whereabouts of an unchanged file that's simply been dragged from one folder to another.

Did you do the moving of the image file in the Finder or do you have a reference library as asked by Larry? In either case moving the files is a recipe for disaster as you've found out. You must either move the files back to their original locations or try to get those photos back into iPhoto as follows:
1 - Find the folder you moved the files into and COPY it to the Desktop.
2 - in iPhoto delete the photos that you're having the problems with as you normally would even though you can't see see them. Also delete all the photos that are in the folder you moved the other files into.
3 - drag the folder on the Desktop into iPhoto to import them as one event. If you get a duplicate warning I'd let it import the duplicate and use Duplicate Annihilator to find them so you can cull out the duplicate you don't want.
Other than that you might have to start over from scratch as follows:
Creating a new library while preserving the Events from the original library.
1 - Move the existing library folder to the desktop
2 - Open the library package like this.
3 - Launch iPhoto and, when asked, select the option to create a new library.
4 - Drag the Originals folder from the iPhoto Library on the desktop into the open iPhoto window.

Why am I being told that a JPEG file that I made changes to in Photoshop 6 (CS6) can't be saved? The message I get says that either the file is locked and I don't have permission to execute this or another program is using this file.

i recently purchased a 21.5 iMac with Yosemite (10.10.1) and was disappointed to discover that my CS6 programs are not functioning correctly. I am unable to use the "Save As" command when making changes to a JPEG file in Photoshop. The message I get says that either another program is using the file or it is locked and I don't have permission to execute that command. I'm experiencing a similar problem in Bridge when trying to move an unwanted file to the Trash. Again, I get a message telling me that i don't have permission to do this. Lastly, I'm unable to open any Camera Raw files. Any suggestions? I had no problems with the Mavericks OS on my old iMac and although it's much slower, I'm tempted to go back to using my old iMac. At this point, I feel as if I've just wasted $2300+ (tax included).

Back up all data before proceeding.
This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
Step 1
If you have more than one user, and the one in question is not an administrator, then go to Step 2.
Triple-click anywhere in the following line on this page to select it:
sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
Start up in Recovery mode. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
resetp
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Error in loading a jpeg file using webutil

I´m using webutil with forms9i and got errors when loadin g jpeg files. I selected some files and worked ok. Some files (ones with blank characters inside their names) blow up the form.
The resultant error message is:

Do you have any info about this error?

It would help if you mentioned which bit of file transfer you are doing there are about 8 different options..
For instance I tried Clint_to_AS with a file name containing a space and all was OK.
webutil_file_transfer.client_to_as('d:\temp\a file.txt','d:\temp\foo.txt',false, null);

Why isn't .jfif not listed in the JPEG file extensions (.jpg, .jpeg, .jpe) Photoshop Elements 12

Problem: Corrupt JEPG files.
Software: Adobe Photoshop Elements 12
Story: On my website I have the option to sell files as instant downloads. I upload JEPG 300dpi images of my artwork for people to purchase is a download. I have done this on Etsy for several years without a problem.
The problem began when I setup a website using Weebly, an online build your own website company. I upload the same files I have used in the past, but when I do a test purchase and download my file it is corrupt. I get an error message in Photoshop Elements that the file is corrupt or missing information. If I let Photoshop open the file, the file it is only half there or lines through the image.
I have been working with a Weebly tech to solve the problem. I sent him the file I wanted to upload. He opened the file on his computer and saved it. Then uploaded to my site, I downloaded it and the file was fine a perfectly clear 300 pdi JPEG file. We were confused. After a few more tests he mentioned he did not have Photoshop and was using Microsoft Paint (light bulb) to open and save the files. His files worked, mine did not.
So I tried opening my files in Paint and saving them in that JEPG format and they work. The only difference i can see between Paints JEPG save option and Photoshops Save Function is that Paint includes the .jfif extension.
Question: Should this make a difference? if so can I add the file extention to Photoshop's list of file types that I can save?
Thanks
Mark

Thank you I will check it out. I am not sure what information is attached to picture files, but the same file saved in Microsoft Paint works in my situation and the Photoshop file will not. The only difference is Paint supports.jfif and photoshop does not. I might want to go the other way jpg to jififs. or save with to jepg with software that supports jfifs.

How to save JPEG files in PSE5.0 ?

OK. newby Q again. how the heck does one know what to choose when it comes to saving an image as a JPEG? the following three boxes pop up:
IMAGE OPTIONS:
QUALITY>
FORMAT OPTIONS:
BASELINE>
PROGRESSIVE>
SIZE:
up to 2 MBps?

Generally, if you're going to archive your photos as Jpegs, you would want to save them in as high a quality as possible. This would be with the slider all the way to the right or number "12".
Usually "Baseline standard" would be the way to go. This writes the photo in one pass to the screen.
"Progressive" writes the photo in 3 passes across the screen, and is usually used for uploading and viewing large files within a web page.
The "size" dialog box you're referring to, gives you the approximate time (in seconds) required to upload the photo with 56.6bps internet. (dial up) At least the time is referenced to dial up internet in PSE5. So the speed dialog box gives you this information, [1st]; size of photo (in KB) [2nd]; time to upload, (in seconds), [3rd], reference internet speed.
If you plan on re-editing your photos at a later date, you should consider saving in a lossless format. Both PSD and TIFF file formats support saving in layers, and don't "recompress" the file each time it's worked on. "PSD" is Photoshop's native format, so it could be argued that this would be the better of the two. Since a scanner in "lossless" mode would save in TIFF, Photoshop would need to convert those files to PSD. A jpeg file would be better suited to a photo in which the editing process has been finalized, and is heading to the printer, or perhaps Aunt Martha in an Email.
A final thought is that the quality you use to "jpeg" a file, and the file size itself, is largely purpose dependent. For example a photo that you intend to make public on "Flickr" should be down sized and and jpegged at medium quality. This in the event that the photo is downloaded, your work will not be at full resolution and quality, therefore limiting its usefulness to viewing only. In any event, a photo uploaded to the web absolutely should be a COPY, do not tamper with an original in the manner in which I've just described.

How to save jpeg files in iPhoto

I would like to be able to make changes in Photoshop and then be able quickly save a jpeg file in my iPhoto library (Version 9). From what I could deduce, the only way to do this would be to save the file to my hardrive, then go to iPhoto, choose the import to library under the File menu and then locate the file I want to import. Is that really the quickest and easiest way to do this? Or is it possible to save the file directly to the iPhoto library from within the Photoshop program?

Using Photoshop or Photoshop Elements as Your Editor of Choice in iPhoto.
1 - select Photoshop or Photoshop Elememts as your editor of choice in iPhoto's General Preference Section's under the "Edit photo:" menu.
2 - double click on the thumbnail in iPhoto to open it in Photoshop. When you're finished editing click on the Save button. If you immediately get the JPEG Options window make your selection (Baseline standard seems to be the most compatible jpeg format) and click on the OK button. Your done.
3 - however, if you get the navigation window
that indicates that PS wants to save it as a PS formatted file. You'll need to either select JPEG from the menu and save (top image) or click on the desktop in the Navigation window (bottom image) and save it to the desktop for importing as a new photo.
This method will let iPhoto know that the photo has been editied and will update the thumbnail file to reflect the edit..
NOTE: With Photoshop Elements the Saving File preferences should be configured as shown:
I also suggest the Maximize PSD File Compatabilty be set to Always. In PSE’s General preference pane set the Color Picker to Apple as shown:
Note 1: screenshots are from PSE 10
Note: to switch between iPhoto and PS or PSE as the editor of choice Control (right)-click on the thumbnail and select either Edit in iPhoto or Edit in External Editor from the contextual menu. If you use iPhoto to edit more than PSE re-select iPhoto in the iPhoto General preference pane. Then iPhoto will be the default editor and you can use the contextual menu to select PSE for your editor when desired.

Can only open some JPEG files in Camera Raw through Bridge CS3

I'm running Bridge CS3 version 2.0.0.975. I always edit my JPEG files through Camera Raw in Bridge CS3. I only have to Right-Click on the file and select "Open in Camera Raw...". However, I've come into a situation where some jpg files will not open this way; the option is not even there.
I have made sure to tick the box in preferences under Behavior "Double-Click Edits Camera Raw Settings in Bridge", and also tick the box under Thumbnails -> Performance and File Handling "Prefer Adobe Camera Raw for JPEG and TIFF Files.
These files were originally 16bit Grayscale TIFF files, but I changed them to RGB 8bit JPEG files.
Also, I know the program works because I navigate to an older photo I worked which is a JPEG and the "Open in Camera Raw..." option is there when I Right-Click, but then I navigate back to the image I want to edit, and the option is not there.
Here are links to my screenshots of what I'm talking about. Both images in the last two screenshots are JPEG:

When I open Photoshop CS3, then go File -> Open As and change the Format Type to "Camera Raw", the JPEG files vanish and I can only see the TIF files. When I open them, it doesn't open in Camera Raw, but rather opens like a normal file would.
That's a fundamental problem right there, and a clue in all this. You should be able to see JPEGs in the Open As Camera Raw dialog.
What happens if you type in the name?
I'm almost convinced you have a file named .jpg but with a different image format inside. Can you put one of these files online for others to try to open?

Can not open JPEG files and can not create JPEG files from other software

Can not open JPEG files and can not create JPEG files from other software (For example from Solidworks).
When I try to right click on a JPEG, a notice window appears written: "Windows Explorer has stopped working - Windows is
checking for a solution to the problem" and then the notice box disapears, the desktop appears and I can continue working.
From the other side - If I try to save as JPEG a screen of Solidworks (like a view of a part) the Solidworks falls but the JPEG
is created (I can see its name in the directory I created it).
I can open the JPEGS with the Paint software if I want but not with the Windows Photo Viewer.
I have the feeling that the Windows Photo Viewer disapeared from my computer - just a feeling.
I will appreciate your assistance.

Hi,
Did Windows Photo Viewer option appear when you right click the JPEG file and select open with?
I would like suggest you use Clean Boot to troubleshoot if there is third-party software conflict:
