Mystery posterization in RAW images

So I was reviewing some RAW files from my holiday photos in Bridge, and I bumped some keys in the bottom left area of my keyboard and ever since, every time I left-click on a thumbnail, the thumbnail changes. It's as if the RAW settings are being altered somehow. For example, with these photos of Moon Jellyfish, the red underlined images are unchanged, while the images following are posterized and crappy in general:
http://i200.photobucket.com/albums/aa50/scarlet_23_images/posterize.jpg
The settings or whatever that are being changed seem to be consistent no matter what the image is of, because in some brighter images the change wasn't as obvious as in the dark blue jellyfish shots.
I've tried resetting the camera RAW settings to the camera default, and opening the files in Photoshop in case Bridge was the problem, but with no luck. I can't find the software CD that came with my camera either so I can't use the factory RAW viewing software instead. I've also tried turning high quality thumbnails on in Bridge and purging the cache, and things appear to go back to normal, but as soon as I try to open one of the RAW files, they go all posterized again. I even completely removed Photoshop, Bridge and all of their settings and reinstalled them but the posterization continues.
Does anyone have any idea what I might have accidentally changed?
I'm on Windows Vista with the CS3 suite and a Canon 350D DLSR.

Forgot to mention, I also tried recopying the affected RAW files from the portable hard drive I was storing them on while on holidays, and they still turned to crap when I tried to open them.
And my Vista OS is 64 bit - could that be part of the problem?

Viewing RAW images in full screen - problem

I have begun to shoot some images in RAW mode with both my Nikon D70 and Nikon D200 - NEF format. I edit in Photoshop Elements, from withing iPhoto so that edited images are saved back to iPhoto.
When I view edited images in full screen mode from iPhoto, the edited version will be shown briefly and then the unedited version pops up. Anyone know what this is all about and can it be stopped?
Also, I am wondering why, when I right-click on a RAW image in iPhoto, one of my choices is "Reprocess RAW" whether I have edited it or not. And there is no choice to "Revert to original" as in non-RAW images.
Marion

I think you are referring to minor color and other editing done within iPhoto. I am talking about cropping and other major editing done in Photoshop Elements. This edited RAW image, by default, is saved back to iPhoto - but NOT as JPEG - where I can view it along with other RAW images I have not processed in any way.
Yet, both edited and unedited images offer me the same option when I right click for the contextual menu - "Reprocess RAW." This is the place where "Revert to Original" appears when this menu is accessed from a JPEG image.
When I use iPhoto edit, which I almost never do, it does indeed save the image as "JPEG image (from Nikon RAW)." And indeed I do then have the option to Revert to Original.
Reprocess RAW works in the same way as Revert to Original. It was just mysterious to me why I was offered the opportunity to redo something I'd not done in the first place.
Thanks for your help.

Imported RAW images are too dark

I'm using Aperture2.0.1 and importing RAW images from a Canon 1D MkIII. All the images are coming in significantly darker than they show in the camera's display. The camera's histogram shows that the images are correctly exposed but they require boosting in Aperture's Exposure panel of anywhere from + 1.15 to 1.5 before they look right in Aperture. That's quite a hefty shift. I get a similar situation in Capture One Pro but the same images right off the card look bang on in Canon's Digital Photo Professional. In Adobe Lightroom it takes a shift of only +.5 to get into the right range. The exposure settings for the test were done with a Sekonic L-758DR meter and manually setting 3 580EX's but the problem shows up in all kinds of garden variety shots with or without flash. My preferred app is Aperture but I'm sick of having to adjust all my shots to get them into range.
Is there something I'm missing here?
Thanks,
Geoff

AMAZING!! Thanks for solving this mystery for me. Disabled the Highlight Priority and the shot comes into aperture looking like I it needs no adjustment. There are some clipped peaks in the histogram so there are some minor blown highlights. If I use Highlight Priority, it prevents the clipping and when I adjust the exposure level in Aperture the shot does look right without losing the highlight so Highlight Priority may be the right way to go when I'm shooting jewelry. But your post explains why the images were darkened.
Thanks again,
Geoff

Canon 350D Raw images not recognised

Hi,
I'm using a Canon 350D (UK version of Digital Rebel XT) and OS X (specifically preview and iPhoto) won't recognise the .cr2 raw images it produces.
The images have finder thumbnails but if I try to open them I get:
The document "xxx.cr2" could not be opened.
Couldn't open the file. It may be corrupt or a file format that Preview doesn't recognize.
In iPhoto I get an 'Unreadable files' alert telling me it can't read them and then lists the files.
I know that it should work fine and am stuck in terms of what I'm doing wrong.
This problem has existed since I was on 10.4.7 when I bought the computer and camera - I'm now on 10.4.9. I did download the Aperture trial to see if that helped and had the same problems. Reinstalling OS X made no difference.
Any ideas?

Imac 20" C2D Mac OS X (10.4.9)

Actually, I was getting support for my Canon Powershot S50 in 10.4.8 (at least I could open the Raw files, although Image Capture mysteriously stopped downloading them from the camera), after doing the 10.4.9 Combo update Preview announced it could not open the files. I went in and hacked this file:
"/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ ImageIO.framework/Versions/A/Resources/Raw.plist"
Changed the entry for Canon S60 (which I don't have) to Canon S50. Preview will now open the files, haven't tried Image Capture yet to see if it is still broken (works fine in Panther BTW). See this discussion in MacOSXHints:
http://www.macosxhints.com/article.php?story=20051101035330228
It worked sort of for me (at least I can open the Raw files I already have).

How can I edit a RAW image in Adobe Bridge and/or Photoshop?

Whenever I drag and drop a photo or group of images from iPhoto. it automatically converts them to jpegs. Even when taken as RAW images. With iPhoto 09, you could do a search of the IMG_#### listed in iPhoto, and a normally-hidden folder full of the original downloaded RAW images turned up in the search. Now, in iPhoto 11, the RAW images newly downloaded DO NOT show up in any system searches (using 10.8.4. It was bad enough when they were hidden... now they are virtually gone.
I want to use iPhoto for organization and some editing, but some photos I want to work with in the RAW format and save as TIFFs. How do I do that?

Whenever I drag and drop a photo or group of images from iPhoto. it automatically converts them to jpegs.
Drag and Drop and Media Browsers access the iPhoto Previews only. No conversion, just the previews.
With 10.8 Spotlight no longer searches within packages, that's to protect the inexperienced user from trashing his or her library inadvertently - as directly accessing the file can do.
To use Raws with an external editor:
First off set your preferred app as an external editor in iPhoto:
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.
Next: In the iPhoto Preferences -> Advanced, elect to use Raw with your External editor:
Now when you go to edit the Raw it will be sent to your external editor.
But there's a kludge here.
iPhoto sends a copy of the file to Photoshop. In the case of a Jpeg you simply save and it all comes back to iPhoto seamlessly. However, if you use a Save As then Photoshop is creating a new file and iPhoto knows nothing about this.
Now here's the catch with Raws. You cannot save a Raw. The work you do must be output to a new file, in a new format (jepg, tiff, whatever). However, as the External Editor is making this new file iPhoto has no knowledge of its existence. Therefore you must save it to the desktop and then import it back to iPhoto as a new file.
This means that you will have your Original Raw and the processed version in iPhoto but they will not be recognised as version and original. iPhoto will see them as two separate shots.

Can't open raw images in Photoshop Elements 9

I've just finished doing a fresh install of Windows 7 x64 SP1 onto my desktop PC. I installed Photoshop Elements 9 but it can't open any raw images (specifically Canon .CR2). When I open one of the same images with Photoshop CS5.1, it properly opens up the image in Camera Raw (6.6), allows me to pre-process the image, then edits it in Photoshop (as you would expect).
Before installing Photoshop, I did manually install Adobe Camera Raw 6.2, then upgrade it (multiple steps) up to the current v6.6.
I also copied the Camera Raw.8bi into the Plug-Ins\File Formats sub-directory of both C:\Program Files (x86)\Adobe\Elements 9 Organizer and C:\Program Files (x86)\Adobe\Photoshop Elements 9 but there was no change of behavior with Photoshop Elements 9.
This was working prior to the re-install of Windows 7.
Any suggestions on how to get this working? Thank you, in advance.

When I to to Help>Update, it offers to update Photoshop Elements to v9.0.3 but no mention is made of Camera Raw (any version). I'm not even sure how to determine what version it thinks is installed since there's no reference to Adobe Camera Raw in the Windows 7 Programs and Feature Control Panel applet.
Suggestions?

Can't open RAW images in Photoshop

I purchased a new computer. It runs 64 bits. I have CS4. Since uploading it to my computer, I can not open RAW images. I have downloaded the most recent updates.
I have been using the 32 bit photoshop because I could not get my NIK filters to work in 64 bit. But I can't open any of my RAW images. I can't open them in either 32 or 64 bit.
I have version 5.0.0.178 of Camera Raw. I only know this because I can see it under "About filer.... Camera Raw". I cant find any camera raw filters in adobe/plug-ins in either version of photoshop. I have a huge photoshoot tomorrow. I NEED to open RAW images. HELP!! Regular Support is down for the next few days.

If you look at this list: http://kb2.adobe.com/cps/407/kb407111.html
You will see you need Adobe Camera Raw 4.6 or later.
As Chris says, update either maually from here: http://www.adobe.com/support/downloads/detail.jsp?ftpID=4681
Or use the Updater from PS help.

Opening raw images in Photoshop Elements 9

When opening raw images in Photoshop Elements 9 (File -> Open or File -> Open As), the Adobe Camera Raw dialog do not open.
Instead I get a window with a progress bar and the text "Reading Camera Raw Format".
The image then opens in the Photoshop Elements editor.
I have tested this with raw images both from Canon EOS 1000D and Samsung WB2000 cameras.
I would appreciate any suggestions on how to solve this issue.
I run Photoshop Elements on a HP netbook running Widows XP and with an Intel Atom N450 / 1.66 GHz processor, 2 GB ram and a screen resolution of 1024 x 600 pixels.

Unfortunately you can't see the raw converter in PSE 9 on screens less than 800 px tall, which means not on netbooks. PSE will automatically convert it for you, but that dialog box and a few others, like the Advanced Downloader window, will not appear.

When opening an image Photoshop Elements 12 is opening it in Camera Raw, it is not a RAW image and it is cropped How do I uncrop the opened image?

When I am opening a .jpg image not an actual raw camera image from Elements 12 it is being opened as a camera Raw image and the image is cropped, I can't find anyway to get the image to uncrop or zoom out so that the entire image is visible so that I can actually edit it to something that is useable. The images were taken with an iPad and copied I suspect using the organizer from Elements 11 but I can't be sure. If I could just uncrop the opened image so that the entire image is visible this would not be a big deal.
Is there a way to uncrop the image that is being opened by Camera Raw? Am I going to have to get my hands on the source of the images (the iPad) and copy the images again using explorer and not let them be copied with the organizer?

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.

In Photoshop CS5 why does Camera Raw 6.7 not open a Crw Raw Image?

I am running Windows XP Pro 32 bit system,with AMD ALthon 2600 processor.When I first installed Photoshop CS5 it would not open at all.After hours on the internet searching for online help from Adobe,L came across a on line chat.They said I needed a update for CS5.I downloaded the update and installed it and Photoshop opened up.Ithought this had solved my problem.Days Later I tried opening some Crw Raw Negatives.They would not open in Bridge or Mini Bridge.So I tried opening the raw image in Photoshop,a box pops up and says photoshop could not complete the task because it was the wrong image type.I have tried to get help in the General discussion forum,so far noyhing has worked.Also I forgot How to get to the online chat site,if anyonehas any ideas or where this site is It would help a lot......Thanks.

Loading a raw image in BufferedImage

Hi guys,
I'm very new to java .I have a raw image which has 32 bit pixels which has ABGR...with alpha as the most signficant byte and the red as the least significant byte. I have an array of ints and I want to load this to a BufferedImage object. I then use a JPanel and render the BufferedImage on to it. I tried doing with other file formats like jpg , gifs and so the rendering to the JPanel works fine. But I'm not able to get the array of ints to be stored in BufferedImage correctly. Could you please let me know what I did was wrong or any suggestions?
Currently I have a class called RGBAImage that reads the raw image and stores it as an array of ints.
So in order to create a BufferedImage I do this roughly,
DataBufferInt buffer = new DataBufferInt(img.getPixels() , img.getPixels().length) ;
// bits red green blue alpha
ColorModel cm = new DirectColorModel(32, (int)0x000000ff , (int)0x0000ff00 , (int)0x00ff0000 , (int)0xff000000) ;
SampleModel sm = cm.createCompatibleSampleModel(img.getWidth , img.getHeight) ;
WriteableRaster raster = Raster.createWritableRaster(sm , buffer , null) ;
BufferedImage bimg = new BufferedImage(cm , raster , false , null) ;Is this how its to be done? I am not getting the image drawn on the panel. Any suggestions or links?
Thank you
Siddharth

I have an array of ints and I want to load this to a BufferedImage object.In your sample code I cannot see how the int array you are talking about becomes the image data. Also, what is the img variable? Please provide a more complete code sample.

How to get Aperture and iPhoto to use Pentax *ist DL RAW images natively

Using some techniques that I found in various places in these forums, I am going to give step-by-step instructions to get Aperture and iPhoto to recognize Pentax *ist DL RAW images natively.
Note: This worked for me using 10.4.6 with the latest iPhoto 06 and Aperture updates. I do NOT know if this will work on older versions of OS X, iPhoto, or Aperture.
Note: If you also use a Pentax *ist DS camera, these instructions will probably disable support for that particular device due to the modifications made to a system file. Only complete these instructions if you want to use a *ist DL camera.
** These instructions involve modifying system level files using a HEX editor. If you are not comfortable with this, do NOT attempt to do this or you could kill your system. Remember, BACKUP BACKUP BACKUP. These steps worked great for me but follow at your own risk!! **
Ok, lets begin...
1) Download this great patch by macintosh_tech
http://idisk.mac.com/macintosh_tech-Public
This patch contains an updated raw.plist file which includes the RAW information for the *ist DL. This patch also contains an updated libRaw.dylib file and an updated Raw Presets file for Aperture.
** Do NOT copy the libRaw.dylib file from this patch to the folder listed in the patch Read_Me. This file did not work on my Intel-based Mac and crashed my system!!
I was able to modify my original libRaw.dylib file using a HEX editor to get it to work on my system. Instructions for this modification will follow.
2) Open the .dmg of the patch in a Finder window
3) Open a new finder window and browse to /System/Library/Frameworks/ApplicationServices.framework/Frameworks/ImageIO.fra mework/Resources
*4) Backup the libRaw.dylib and Raw.plist files. Copy them to a safe location. For extra safety, you can just copy the whole Resources folder to a safe location (Make sure that you COPY it and dont MOVE it)*
5) Right-click the libRaw.dylib file and select "Get Info". Look at the bottom of the info window and expand the "Ownership & Permissions" tab. In this section, expand the "Details" tab. If the lock icon is in the locked position, click it to unlock it. Change "Owner" to your user name. If requested, enter your system password at this point. Close the info window. This step lets you modify the libRaw.dylib file.
6) Complete step 5 for the Raw.plist file.
7) Copy the Raw.plist file from the "Place In System Folder" folder from the patch to the Resources folder. It will ask you if you wnt to overwrite the existing file. Click "Replace".
8) Open a new finder window and browse to the /Users/YOURUSERNAME/Library/Application Support/Aperture/ folder.
* 9) Backup the "Raw Decode Presets.plist" file *
10) Copy the "Raw Decode Presets.plist" file from the "Place In Home Directory" folder from the patch to the /Users/YOURUSERNAME/Library/Application Support/Aperture/ folder. Click "replace" if it asks you.
11) Here's the tricky part. Download a HEX editor if you don't have one. I used 0xED. It is free and can be downloaded from
http://www.versiontracker.com/dyn/moreinfo/macosx/29521
12) Open the libRaw.dylib file from the Resources folder in your HEX editor.
Note: This is your original libRaw.dylib file from your /System/Library/...../Resources/ folder, NOT the file from the patch.
Use the Find function and search for the string "Pentax *ist DS". Make sure you are using "Search Type: Text" (or equivilent in your editor) and that you use proper case. When you find this string, change the "S" in the "DS" to an "L". The string should now look like "Pentax *ist DL". Use the "Find Next" function to find the next instance of "Pentax *ist DS". Again, change the "S" to an "L". There should be two total instances that you need to change. Save the file and exit the editor.
13) Open Disk Utility and repair permissions. This will set the raw.plist and libRaw.dylib files back to their original permissions.
14) Reboot the system.
15) You should now be able to view .PEF files natively in Aperture and iPhoto. I appologize in advance for any typos. Let me know how this works, as this is my first tutorial of this nature.
Macbook 2.0 Mac OS X (10.4.6)

It would appear that my last post was a moot point as the 10.4.7 update adds support for the *ist DL. It's nice to have it biult into the operating system now.

Automatically export to JPEG from RAW images

RAW images are preferred form of shooting for many photographers. And, Lightroom is great at managing and developing these images. However, we increasingly use/view these images outside Lightroom and away from the PC where we do most of the development. For example, I use a DLNA server which shows off my entire image collection to big screen television (which can act as a DLNA client). The same DLNA server is used to send images to our smartphones (my wife loves to show all kid pictures anywhere she - without having to carry the pictures on the phone).
Most other applications that use these images, do not work on RAW images and JPEG images must be exported manually from Lightroom. This becomes increasingly difficult to manage and keep track of while developing RAW images. How many RAW images need to be exported? How many images did I touch since the last time I exported them?
Currently, I am using the following process to manage this:
1. I created a smartlist which contains images that are edited after "a particular date".
2. I select all images in this smartlist, and use Lightroom3's export function to export them all as JPEG, to the same folder as original.
3. Once the export is completed, I modify the smartlist to change the "particular date" to today's date.
I plan to repeat this procedure every so often (once a week or so).
It would be great if Lightroom had a feature such that it always keeps "JPEGs exported" for all RAW images (with the latest development settings of course). This could be a process that could occur in the background or at a user-specified time/event (e.g. when one closes Lightroom). User should be able to specify where the exported JPEG images should be put to and with what name (I prefer in the same folder as RAW but other users may have other preferences). User should be able to select if this is only done for RAW images or also for JPEG and other formats (in which case, should the exported image override the original or not). The exported images should be (optionally) automatically included in the Lightroom catalogue and stacked with the original RAW image.
Mainly, the entire process should be completely transparent to the user. A collection of JPEG images - corresponding to the latest development settings for the RAW images - should be always available.
Osho

I've heard many others raising the issue of an auto-jpeg feature - kinda like auto-write xmp, except auto-write jpeg.
I agree this would be nice, obviously some sort of "stability" check would be needed so it isnt constantly writing jpegs as you edit. Lightroom employs a form of this already for the xmp - meaning it doesn't update xmp every brush stroke, but accumulates several strokes before updating, so its more efficient...
If you could define multiple jpegs to keep - with the raws, or a separate tree - even better. That would obsolete all the tree output plugins and publishers.
The publishing feature was intended to fill this need (albeit manual only), but it suffers from the inability to publish to original directory, and/or an external tree.
I'd like to see a manual mode too, that accompanies a new "Done for now" function - so when you say "Done for now", it saves xmp, jpeg(s), snapshot, and optionally locks the file so unapproved changes can no longer happen to it. Then if you could define multiple "done for now" presets that include initiating publish service and exports, then the work-flow becomes: 1.import, 2.edit, 3.done for now - and thats it (maybe repeat 2 + 3 in the future). i.e. no more manually initiating the exports, publish services, snapshots, saving of xmp, ..., and whatever else you do when you're done.
In the mean time, I may make some of this part of an up-n-coming "Sidekick" app + plugin combo when I get to it.
Presently, I dont use publishing services, and I have ExportManager to consolidate exports (which includes TreeSync), so my workflow is: 1.import, 2.edit, 3.done for now (save xmp+snapshot, and lock via ChangeManager), 4. initiate consolidated exports...

Cannot view raw images in iphoto 11

Hi there, I have just upgraded to a new imac running Mountain Lion and iphoto 6.
Now I can't view the latest raw images I have taken (on my canon eos 550D) - When I scroll through the images they appear for a second or so, then they disappear and are replaced with empty boxes with dotted lines around the outside, when I double click on them, I get an exclamation mark inside a triangle.
?? Any idea why this is happening? I saw that my camera is one that is supported by iphoto so am confused as to why this is happening.

The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

TD
