How does ACR save edited JPEG and TIFF files?

When a JPEG or TIFF file is edited in ACR, are the edits destructive when you click the "Done" button, permanently changing the file? Or is the edit info saved in sidecar files like with edited RAW files, not affecting the original file?
If I reopen a previously edited JPEG file in ACR, will the adjustment settings be the same as where I left off, allowing me to change those edits, like a crop or HSL adjustment? Thanks.

First: There is a Camera RAW Forum.

Second: It should be fairly simple to test your hypotheses.
And on my station at least it appears the data is stored in the file and not as a sidecar-file.

Exif tool and Export Jpeg and Tiff files

I run Lightroom 4.4 under Apple OS X10.4.4
When I export files Exif Tool (in Graphic Converter) under ICC header shows for Jpeg "Primary Platform = Microsoft and for = Tiff Apple; and under ICC Profile Color profile for Jpeg = HP but Adobe 1998 for Tiff. I can see that there is a difference between the profile for Jpeg and Tiff (eg sRgb and Adobe1998) but don't follow why the Primary platform differs and shows Microsoft for Jpeg and that the jpeg profile is HP. Can anyone explain, please, and dose it matter anyway? Thanks Clive

A overview of ICC profile tags is here: http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/ICC_Profile.html
Why the difference in the PrimaryPlatform tag, I don't know, it does not matter.
The ProfileCopyright tag is HP for sRGB, Kodak for ProPhotoRGB and Adobe for AbobeRGB (1998) of course.

Can I automate the writing of XMP metadata into JPEG and TIFF files?

I have written an ASP.NET 3.5 website application on behalf of an annual international photographic competition. Entrants will be uploading digital photos in either JPEG or TIFF format. Ideally, I would write entrant identity and image title information into the XMP metadata for each image immediately after upload - but so far, I have failed to find any way to do this in ASP.NET.
Thousands of images are involved, so I need to find a way to automate the metadata insertion, perhaps with some sort of script that uses a text file (extracted from the SQL Server database on my website) as the source of the metadata for a batch of images. Is this the sort of task that can be done by writing a script for Bridge CS3? Are there any scripts already in existence that I could use? I am a total beginner in this area.
I use a Win XP PC, though I have a colleague who, I think, has CS3 on his Mac (running under the Leopard OS), so scripts for either platform might be usable.

I use images for presentations. Recently I've noticed a decrease in quality ( sharpness and definition) of pictures copied into Keynote. Same problem with both JPEGs and TIFF files. I've recently upgraded to keynote 09, but with no improvement.

I use images of paintings for presentations. Over the last 3 months or so I've noticed that I cannt copy images (either JPEg or TIFF) without a reduction in sharpness and definition. Hope someone can help with this problem.

Figured it out myself! yay! (only took my entire moring)
The solution:
Dont print to PDF!
SAVE AS COPY, then select Adobe PDF and click SAVE, this will bring up a dialog box with the options you need (including the "High Quality Print" Adobe PDF Preset)
This was not clear in any of the instructions i read

How can I save the decuments and PDF file?

How can I save decuments and PDF files?

You first need an app on your iPad that supports the type of document that you want to store on it - unlike a 'normal' computer the iPad doesn't have a file system, and everything on it has to be associated with an app.
The options include Apple's Pages app for Word documents, Numbers for Excel spreadsheets and Keynote for Powerpoint. And from third-parties apps such as Documents To Go ('premium' version) and QuickOffice Pro HD.
For PDFs there are free apps such as Apple's iBooks app and also Adobe Reader - and paid-for apps such as GoodReader (which also supports read-only of word and excel documents).
As to how you then get the file to your chosen app will depend upon what the app supports - different apps have different ways of copying their content to/from a computer e.g. via the file sharing section at the bottom of the device's apps tab when connected to iTunes, via your wifi network, email, dropbox etc. For iBooks you can add PDFs to your computer's iTunes via File > Add To Library and then sync them to the iBooks app via the Books tab. For Pages, Numbers and Keynote there is help here.

How does LR3 handle virtual copies and xmp files?

Hi,
I see only 1 xmp file and yet I have several virtual copies of that same photograph... where are the corresponding xmp files? I am using exiftool to place some info in the CR2 files and then need to update the corresponding xmp file...
Thanks,
Juan

Hi Juan,
Virtual copies are only stored in the LR catalog, never in the XMP sidecars. If you update the XMP using exiftool and update the metadata in LR, both the original and the virtual copy will be updated with the XMP data.

Does ACR save JPEG & TIFF files like RAW files are saved?

I know ACR saves RAW file edits to side-car files, not permanently changing the original file. Does ACR do the same for JPEG and TIFF files when they are opened, edited and saved? Thanks.

I wonder if Kelby could have been confused by the fact that the metadata describing the Camera Raw settings is being stored back into the JPEG file. The key is that the JPEG file is indeed re-written, but the actual image data is not changed.
Here's an experiment you can try for yourself:
1. Start Photoshop, and choose File - Open As...
2. Change the type to Camera Raw, and choose a JPEG file that you have on your disk, and press [Open].
3. When Camera Raw comes up, push the Exposure control all the way to -4.00 EV and press [Open Image].
4. Note that it's very dark, as expected.
5. Close the document, do not save.
6. Note that the JPEG file has been updated on your disk by seeing that its date and time are current.
7. Choose File - Open As... again and open the same JPEG file.
8. Note that the Exposure control is set again to -4.00 EV and the preview is very dark.
9. [Cancel] the Camera Raw dialog.
10. Open the same JPEG file from Windows Explorer using the Windows Photo Viewer. Note that it is NOT dark. The original JPEG data is still intact, as bright as it ever was.

Edit jpegs or tiffs using Raw interface in Elements 10?

     Hello- When I was using Elements 8, I could easily edit jpegs and tiffs in the Photoshop Raw interface.
      (I know that's not the same as an image originally shot in Raw, but nevertheless it was very useful in some situations.)
      Now I'm using Elements 10, and either I've forgotten how to do it, or it can't be be done. Can anyone give me some instruction?
Thanks!

Hi Dominic - Thanks for the reply ... but I think I must be missing something obvious.
First, FYI I am using a Mac. In Elements 8, I was doing exactly what you suggested, and it worked fine.
With Elements 10, I see no button to switch to Camera Raw. (I can convert to Photoshop Document (PSD,) or save to Photoshop Raw, but tneither of those brings up the RAW interface. If you or anyone can point me to something I must not be seeing, please let me know!
Thanks Again

How can I save a page and all its component parts in a single file, like IE does as an MHT - it's much easier for mailing to people where page address not available?? (as in output from an airline booking site, for example)

how can I save a page and all its component parts in a single file, like IE does as an MHT?
It's much easier for mailing to people where page address not available?? (as in output from an airline booking site, for example)
It is simply too painful to have to zip everything up into a single file to send. MHT format has been available for years now from IE, and with every new FF release it's the first thing I look for. I have been using FF for years, and hate having to come out of it, over into IE |(which I even took out of startup) and key everything in again, in order to send somebody something in a convenient format that they can open with a single click.
I can't believe this hasn't been asked before, so have you looked at it and rejected it? Have MS kept the file format secret?
Thanks
MG

This is not really an answer just my comments on your question.
I am sure I recollect efforts being made to get mhtml to work with FF.
Probably the important thing to remember about .mhtml is that if other browsers do support it they may need addons, and may not necessarily render the content correctly/consistently.
There are FF addons designed for archiving webpages, you could try them, but that then assumes the recipient has the same software.
You could simply save the page from FF to your XP pc; then offline open it with and save it using IE, before then emailing using FF, and attaching the .mht or mhtml file that you have now created on your PC.
As an alternative method, in some cases it could be worth considering taking a screen grab of the required page, then sending that to the recipient as a single email attatchment using either a bitmap or jpeg file format for instance.
Something such as an airline booking may be designed with a print option, possibly it could be worthwile looking at sending the print file itself as an email attachment.

New to using Firefox with MAC: How does one save a single jpeg image from the web (as in a right click on a pc?)

New to using Firefox with MAC: How does one save a single jpeg from the internet, similar to using the right mouse click on a pc?

If your question comes about because you have a single button mouse, it's time to visit your local computer store and get a ''real'' mouse for that MAC. I don't "get" Apple, they sell their hardware for almost twice what a comparable PC would sell for - and then they leave out what is probably the most important time saving control, the right-button.
See this for setting the hidden pref for context menus in Firefox, for Mac's.

Hi, I'm in LR changing my picture, and I couldn't find the save button.Does this save a .jpeg somewhere?

Does this save a .jpeg somewhere?

The edits you do in LR are non destructive, and are saved automatically to the catalog, so there's no need for a Save button.
If you need a jpg for a particular purpose, select the image in the Library, and click Export.
The export dialog lets you fill in size, resolution, color space, sharpening, etc.

Open Jpeg and tiff in ACR as a choice

It would be nice to be able in choosing wether to open jpeg and tiff in ACR using right mouse click menu. AFAIK now you only can set preferences to open these files always in ACR or never.

Truly dumb question. How do I get PS to actually complete a command, eg straighten an horizon, and finalise the change. Even doing a "save as" with a new file name and reloading brings the image back, straightened, but with the skewed back ground frame st

Truly dumb question. How do I get PS to actually complete a command, eg straighten an horizon, and finalise the change. Even doing a "save as" with a new file name and reloading brings the image back, straightened, but with the skewed back ground frame still there. Is there a "apply change" or similiar command that I simply cannot see.

brings the image back, straightened, but with the skewed back ground frame
PSE did what you told it to do. Choose the Straighten and crop edges or fill edges options when you use the straighten tool if you want it to do more than just straighten the contents of the image. Many people prefer the plain straighten because they'd rather crop themselves than let PSE do it.

How to save raw images as TIFF files on Adobe Bridge?

I am trying to upload my raw images from my camera onto Adobe Bridge and save them as a TIFF file. But it does not give me that option and simply automatically saves them as JPEGs.
Where is the option to keep them as raw, large TIFF files?

This is the Adobe Reader forum. Your question is concerning about what software?

Where does PSE10 save edited photos?

Where does PSE10 save edited photos? When I use PSE File / Open Recently Edited file, it displays 10 files. How do I access are all the other ones I have saved? I have tried using iMAC Finder with no luck.

edited photos are saved in the modified folder in the iPhoto library
However - that is not the place to access the modified photo - you never need to go directly into the iPhoto library is it is advisable not to - there are no user serviceable parts in it
