Magenta color cast problem on canon 7d raw files

when i import canon raw files (cr2) into lightroom 3, i get a magenta color cast over the whole image. the thumbnail image looks fine, but when lightroom opens up the image, it get's a magenta color cast over the whole thing. i shot raw+jpeg mode too, and there's a huge differnce in color between the two. the jpeg looks like how i shot it in camera but the raw image has the ugly magenta color. not only do i get this ugly color, but it seems like there's added noise compared to jpeg image.
i tried converting the cr2 into a dng. but when i open that in lightroom, i get the same problem.
i use aperture 2.1 (i only use the lr3 trial so far), but i have the same problem there.
i use cs3 but i downloaded cs5 trial.
acr i have is 6.1
help.
thanks.

Go to develop and the callibration tab and change it in the pull down menu to a canon default like 'Neutral' and not the adobe one which is made by somebody totally colour blind or obviously a Nikon fan.
Although this is weird as the problem for me has always been canon JPG's with the cast and not the RAW.
Also check your white balance cause Lightroom seems to change it whatever.. 'AS SHOT' is a big fat Adobe lie so use a preset from your camera in the drop down box.. Why? I shoot with Canon's flash WB setting which i know to be 5500k with the tint at zero. On import, Lightroom changes it to 6150 and adds an amazing +7 on the magenta tint, if i chose 'FLASH' things suddenly turn to what i see on the camera LCD.. I'm sure that is where the big fat tint has come from since day one.

Problem with Canon G12 RAW file

I'm very disappointed because I can't use Lightroom with my new camera! I have this issue since LR 3.3. and CR 6.3 started to support Canon G12's raw file. Any raw file is decoded incorrectly, picture is grained, it has a lot of noise at any ISO (even 80 or 100). The defect is noticeable only at 100% zoom, not at 50% or other sizes.
I tried to do also a clean installation of LR 3.4.1 and CR 6.4.1 but the problem persists. (I use LR 64 bit on Windows 7 64 bit; with PS 12.1 64 bit I have the same problem)
Yes, the camera is ok, and with Canon Digital Photo Professional 3.10 all is perfect, the same picture is amazing.
Is there any solution please?
Thank you!
Davide

It may be that DPP knows how much default noise reduction to apply to your G12's raw images and Lightroom doesn't.
Can you adjust LR's noise reduction sliders to get a better image? If so, you could make that amount of reduction a default.
If that doesn't work for you, could you post a sample raw image somewhere that we could bring it into Lightroom and see what you are writing about?

Problem Opening Canon 1100d Raw file with Lightroom2

I have dusted off an old copy off lightroom2 and installed the updates, but It wont import RAW from the 1100D, Jpeg no problem. Is lightroom2 too old? Should it work?
I get a message saying file not recognised or corrupt.
Any advice would be greatly appreciated.
Thanks
Aaron

Yes to your "Is it too old" question, I'm afraid. Raw support for that model was not introduced until Lightroom 3.4 (which you can no longer purchase). Your options are either to upgrade to LR5 (assuming your hardware and OS is capable), or download the latest version of Adobe's free stand-alone DNG Converter and use this to convert your Raws to DNG which your LR 2 should be able to read.

Problem with Canon 6D raw files on LR "4.3"

Hi
I am having some problems with LR 4.3. This is what happened after I import my 2nd batch of 6D raws to the library (300+ photos). 1st batch of <30 raws were ok. I have yet to do basic troubleshooting but this is something never happened to me with my older cams and older LR versions.

The import operation of LR has a backup to an alternate location function which is normally how you'd recover from this sort of situation--retrieve things from the backup location. Presumably you don't have backups for anything, though.
I’d try it in another computer, at least, and see if it comes back to life. The easiest thing to try is recover the photos off your memory cards. Google for photo-recovery programs.
If a hardware component on the drive, itself, failed, then there’s probably nothing anyone outside the factory can do, and then maybe not, either. It would involve swapping the data-storage portion of the device to another device with its circuitry intact and seeing if things started working again. This would only work if the data-storage portion of the device was still ok and the other circuitry had gone bad.
If something on your computer wrote bad-data to the partition table or boot areas, then the files, themselves, may still be there and findable by a low-level recovery program. Google for hard-drive and partition recovery programs:

CS3: HDR Merge Problem with Canon 50d RAW files

I recently upgraded from a 20D to a 50D. I'm running CS3 under WinXPpro with 3GB of RAM. HDR merge of 3 CR2 files is causing CS3 to generate a program error and crash. This never happened with my older (smaller) files from the 20D. Anybody know how to fix this?
TIA,

The suggestion was to try an HDR with smaller 50D sRAWs as an *experiment* to see if the size matters more than the camera model. Another benefit of a 50D would be the 14-bits per pixel instead of 12-bits and an sRAW would have less noise per pixel than a full-size RAW so using smaller sRAW images might work better than a 20D's.
The "size" being referred to is the dimensions in pixels, not the on-disk size, becasue the in-memory size of an image should be similar whether it comes from a 16-bit TIFF or an 16-bit RAW conversion.
Merging RAWs will involve ACR during the HDR process, whereas merging TIFFs won't unless you have the setting to prefer ACR for TIFFs, too, which you don't indicate.
There can be data in the highlights and especially shadows from a RAW that gets thrown away when it's converted to TIFF, so merging RAWs is better than merging from TIFFs.
I currently have CS4 only on my machine so I forget, but with CS3, does it matter what output size you have set in ACR, when you do an HDR conversion from RAW? In other words, does HDR using ACR ignore the output size or not? If not, then perhaps setting a smaller size in ACR (the same area where you set the bit depth and conversion colorspace) would make things work or setting a larger size with 20D images would make them fail. This is being suggested as a experiment as well, to try to isolate the issue, not necessarily a permanent solution.
I don't think there is anything inherently wrong with a 50D RAW that would make it not work, but the larger size would use more memory and maybe your machine is getting close to some sort of limit.
Other suggestions would be to reset your preferences and check your disk(s) with scandisk and/or change your scratch-disk to somewhere else to make sure there's no some corruption keeping the HDR process from working with the larger 50D images, and along those lines, also try purging your ACR cache or moving it to another drive. You might also try changing the amount of memory available to Photoshop (ram vs scratch-disk) in the Preferences.
What module does the crash occur in, if the error says? Is it related to display or something else?

Problems with Canon 7D RAW files

I am using Elements 8 with Bridge and how downloaded and installed the latest ACR (version 6.2). I have also purged the cache for all folders on my iMAC, but the CR2 files still show only as blank icons. Any idea what to do next?

ACR is not expected to generate preview thumbnails in Windows Explorer.
You will not see thumbnails nor be able to preview your .CR2 files on a 64 bit system without the installation of a special codec to do the job. If you haven't already noticed, you can't even normally see thumbnails for .PSD files either (and this, at least, Adobe really should provide).
I use and recommend the FastPictureViewer Codec Pack, which will enable .CR2 thumbnails as well as (with just this week's release) .PSD thumbnails. It's inexpensive, and helps integrate your digital photography into your computer environment. I have no affiliation with this product, other than being a satisfied user.

Some Canon CR2 RAW Files Will Not Open In Elements 8

I use a Canon 7D DSLR. Up until 30 minutes ago I never had a problem opening Canon CR2 RAW files in Photoshop Elements 8.
Some files still open others do not. I can think of only one thing. I was shooting a large number of frames and reduced the RAW Image size down from RAW Large Only to RAW Medium with Small Jpeg to give me more room on the Compact Flash Card.
The Large RAW only CR2 files open fine in PSE 8, the Jpegs open fine, but the smaller sized CR2 files will not open and I get a wrong file type message in PSE8.
Any ideas why this would happen? I suspect it is a function of the camera setting, but all RAW files download as CR2 files.
I appreciate any guidance in this matter. Needless to say I am resetting my camera back to Large RAW files only.
Alex

ACR 5.x only supported full-sized 7D RAWs, but ACR 6.x supports 7D mRAW and sRAW, so just update to the latest version of the plugin, following the PSE-specific instructions:
http://www.adobe.com/downloads/updates/
sRAW and mRAW files are not RAWs because the camera has already demosaicked them to RGB and encoded them as lossless JPG.
Here is technical information on the reduce-sized RAWs:

Can't open Canon 6D raw files

I'm using windows XP and Lightroon 2.7, and am having problems opening Canons 6D RAW files, I can use CS6 but I like LR better.

You need LR4 to open file from 6D. And LR4 doesn't run under win XP.

LR 4.2 D600 deep shadow magenta color cast

LR4.2 gives some ugly magenta color cast on deep shadows especially at high iso pictures. Nikon Capture NX2 gives them too, but not so heavy. If I push the shadows at iso 1600, they are all magenta. Is it related to the beta state of the D600 support? My D700 is at iso 3200 in deep shadows completely black (only luminance noise), even pushed. Is there a possibility to correct that issue with LR (high iso blackpoint correction)? The shadow color tint correction from the calibration option is not really a solution, because it does not only correct the deep shadows, so the other shadows get a green tint.

i also face this problem...
It appears the magenta shdow area in the above shot is confined to the bottom edge of the image. I just discussed this on a similar post concering a Canon 5D MKII with the same issue in the bottom corners of the image. I suspect it may be due to light entering the viewfinder and leaking into the mirror box:
http://forums.adobe.com/message/4843206#4843206
It's simple enough to try similar shots with the viewfinder blocked. When I shoot images on a tripod I always make it a point to block the viewfinder with the Canon strap mounted blind, a hat, or even my hand to keep direct light from entering the viewfinder. The only thing between your viewfinder and the image sensor is the foam seal that the mirror rests on in the up shooting position. At high ISO even the tiniest light leak could cause fogging of the image, and it will be most visible in the image bottom edge or corners (i.e. image is upside down on the sensor).

Can someone please help a new owner of a Pixma Pro-100 with a color cast problem?

Despite setting it up correctly with the drivers supplied on the CD for my Windows 7 64-bit laptop, I'm getting a slight pink color cast on both Canon's Fine Art Museum Etching and Glossy Plus II papers. It is neither a monitor calibration nor a software processing (white balance) issue, since I printed exactly the same file on my old Pixma IP4840 without any problem whatsoever. Unfortunately the IP4840 cannot handle the heavier grade media, nor print exhibition grade quality.
I have tried adjusting the C, M, Y values according to the print pattern as recommended, without any significant improvement. I have used both the Pro and ICC profiles with similar lack of success.
In desperation I downloaded the 32-bit driver to try on my Windows 8 desktop, also to no avail.
I'm sincerely hoping there's a simple solution to what has thus far been a disappointing debut to the Pro series.
Kindest regards,
Richard

no, I didn't ask to burn a picture....this is why I am confused to how the picture got on there.
I understand what you are saying regarding the multi-session thing (how do I avoid this if my other cds with photos on them have this, and I don't know they do?)
but what I do know is that cd had photos on it (it definately wasn't full, and maybe that is why I haven't had a problem with others...they have all been full) and no one else uses my Mac, so I know no one else put the picture on that cd. I may have inadvertantly burned the picture, but if I did, I don't know what I did to make it burn the picture onto the cd.....
The only thing that happened was I opened iphoto so I could save some of the pictures that were already on the disc, but when I went to look for the pictures on the cd, the only thing that was on it, was an iphoto picture....which I didn't ask to be put there.....
I have previously burned pictures onto CD using my Mac with no problem, and I've pulled pictures off CD that were burned using a PC. So I guess I need to know how to determine if the cds have this multi-session thing going on?

Problem opening Canon 6D RAW even after upgrade today to PS CS6, WinXP-SP3

Givens: PS CS5>CS6 upgrade via $199USD download today, Non-CC upgrade. OS: WinXP SP3, camera: Canon 6D RAW (.CR2 files) and prefer to work on RAWs via Bridge.
Main goal: view Canon 6D files in Bridge, do adjustments, open via ACR into PS CS6 for further work.
My fav workflow for photos is: Bridge>ACR>PS. Just got a Canon 6D camera. So I updated to PS CS6 today and I did go through PS CS6 menu: help>update mechanism for all available updates, which was one round of ACR (and Bridge) updates, no more were offered. That brought ACR from v7.0.0.308 to v7.1.0.354--still could not see Canon 6D RAW files. I went to Adobe.com and did manual download for ACR/DNG 7_3 but it did not enable Bridge to see my new camera files nor could I open the 6D .CR2 files in PS. Got PS error message about not recognizing filetype, update ACR, etc (which of course I just attempted). (Seems as through PS and Bridge did not know the ACR/DNG 7.3 "existed" IF that is a capability).
Then I tried to install ACR 8.7 from the "Fix your 6D RAW problems page" and got error messages in PS CS6 (perhaps bc I am on 32-bit system). Decided to start from scratch; uninstalled PS CS6 upgrade.
Secondary issue is: Now I have uninstalled PS CS6 and done System Restore to the point just after I downloaded PS CS6 upgrade. I want to reinstall but the installer fails. Support chat told me to download PS CS6 Upgrade again (doing that now), then reinstall.
Solve: Main problem: Be able to work on Canon 6D RAW through Bridge and ACR (prefer NOT to workaround with DNG if possible) At time of writing, as mentioned, I am downloading PS CS6 upgrade again, then plan to reinstall. If that works, then I need steps to update ACR so that I can work on 6D RAWs through Bridge and ACR. Please know that going through Photoshop's Help>Update mechanism does NOT seem to work. Do I need manual updates? If so, please direct me to the correct ones and order of procedure to execute this upgrade successfully.
Many thanks, Paul

Yammer, thanks for the info about Camera Raw 8.3--that is my goal to load PS CS6 Upgrade and update to Camera Raw 8.3 Currently, I am having problems installing PS CS6 upgrade after uninstall. I have used Adobe CC Cleaner several times. It seemed to help, and the installer proceeded further with next try. Then I looked and there was no PS CS6 icons. I have done system restore also several times and am about to try again. It seems that my original PS CS6 upgrade installed, but when I tried to load ACR update, problems arose. Is there a way to remove recent version Camera Raw remnants from my computer. There is no Photoshop CS6 folder and further none for the CameraRaw.8bi for PS CS6. One possible clue: Yesterday I did two upgrades: 1) PS CS4>CS5 via box, then 2) PS CS5.CS6 on-line download non-CC. In one round of update, I saw that PS CS*5* Extension Manager failed to update. Seems unrelated but mentioned here for thoroughness.
Running ACR 8.3 in XP SP3 would be most useful and timely today as I have work to do. Many thanks, Paul

CS4 won't read Canon T1i raw files

CS4 won't read Canon T1i raw files. Is this a known problem? Is there an update or plugin that I need to download? If so, where can I find it? Thanks for your help.

T1i support was added in Camera Raw 5.4. It sounds like your Camera Raw may be out of date.
From within Photoshop, choose "Updates…" from the Help menu. It'll do its thing and eventually Adobe Updater should tell you updates are available. Run through that install process and you should be set to go.
Note that you will have to quit Photoshop during the installation process, so make sure all your work is saved.

CS5.5 and Canon 6D RAW files

I got CS5.5 and now I bought Canon 6D but although updated Camera Raw does not support Canon 6D RAW files (CR2). What is the problem?

The 6D is not supported until ACR 7.3 so you need to upgrade your Photoshop to CS6 or CC or use the current version of the free DNG Converter to convert your images to DNGs, first.

IPhoto choking on canon 30D raw files

Tried to run a pro shoot through iPhoto but it appears to be choking on Canon 30D raw files (.cr2 extension). I'm getting an assortment of odd problems (missing or oddly rendered images, saves that never finish, sliders that take 30 seconds to move; times when moving the white balance slider has no visible impact on the photo) that basically have left me scratching my head about iPhoto (at least with Canon 30D raw). I was using features like Duplicate and saving edited raw files as TIFF but those are all documented features and so I would expect them to work properly.
Is anyone successfully using iPhoto with 30D raw files?
I have Aperture and it works great with the same set of raw files but iPhoto is so quick and easy (which saves time but also means that it's easier to get other team members involved in the workflow) that it's tempting to use it at least as the front-end for selects and preliminary development. Or maybe iPhoto is just for jpegs at the end of the day even though it does seem to have a fairly capable raw converter?

Tried to use with Lieca Raw also errors.

When will iphoto accept Canon 40D raw files?

When will iphoto accept Canon 40D raw files? I have a new camera and would love to use the raw files in iphoto. No luck so far. Aperature seems to lack the abilty to open them also. Anyone here as to when iphoto will be updated?

Hi again.
No, I don't use aperture, I tried the demo and liked it, but I'd previously bought the commercial version of Pixmantec RawShooter converter for my 10D - Pixmantec were 'bought out' by Adobe, and Adobe generously offered all RawShooter purchasers a free licence for Lightroom, which I also like a lot (though haven't fully got to grips with), so can't currently justify Aperture too.
The one thing I'd say about Aperture is that the colour management for some reason just nailed the colours when printing using canned profiles, in a way other apps hadn't on Windows (including QImage). I was particularly impressed by this using an old Epson 1290S A3+ printer which always tended to produce prints with a colour cast.
iPhoto seems to handle RAW conversions very well and simply, although it's not as refined as the high end apps. This together with organising features are probably what make you find it so easy. Remember though that when you display/tweak RAW files, iPhoto will be creating a file to store these changes as the RAWs do not get directly manipulated. As all this is done behind the scenes again this probably makes it seem easy.
If you don't have Aperture or Lightroom, both were available for 30 day demo last time I checked.
