Posted this question on the Canon 5dmk3 thread then discovered this forum which is probably more relevant.

I'm getting an intermittent fault whereby when I open the CR2 file, using the Camera Raw 8.3 interface from within Photoshop, the occasional photo has a green cast to the entire photo image which is hard to remove.

However what confuses me is when I review the same file in Faststone Viewer, the image is shown correctly.

Any ideas anyone / what is the simplest way to remove a green cast.
 
Does altering the tint slider not remove the colour cast?
 
The green cast in question was a lot more severe than that example used in the link kindly supplied by Dean.

I tried the white dropper tool on a small portion which was a white green than the rest of the image, and it put the colour slider right to the far right end and the photo still had a tint to it - wondering if there are any tricks available to extend the slider length from the 150 setting.

Going to try a different brand of memory card incase this one is on its way out with unreliable recording of an image
 
If you shoot jpg + raw how does the jpg compare?
 
What happens when the image is viewed on the camera LCD, is the colour cast present or not?
 
Just thinking aloud - if it had been a software glitch then more photos in the session would have been affected. I wonder if some form of colour corruption in transfer from the CF card to the PC could be the culprit. One thing I can try next time it happens, is to copy the file from the camera a second time and see if it clears then.

Faststone 'should' have seen the same colour corruption but it doesn't appear to have. They are full RAW files and not SRAW etc?
 
looks like adobe is opening raw as an 8 bit file to make it produce an image like that. have you checked the adobe defaiult preferences
 
check Color Settings under the Edit menu and make sure they are set back to their default values. It might also be worth checking the preferences of your graphics card if you are using graphics card acceleration. I'd try disabling it first and see if that fixes it, if not, I'd leave it as is. It can be found under Performance in the Preferences
 
have you tried changing the WB in ACR. it could be faststome is correcting the issue and that the images were shot under an incorrect WB. i know when shooting under fluorescent with incorrect settings you can get this esact problem. obviously your shooting outdoors so your not under fluorescent but it could be an incoorect setting that caused the issue
 
Hi Dean, thanks for the suggestions will review all of these today just incase.

Immediate thoughts though are

Adobe 8 bit - as photos either side of this image are fine and no settings are changed I dont think it will be this

White Balance - same applies and I always use Automatic anyway - and as mentioned the photos either side with identical settings were fine

cheers
 
Surely the best way to eliminate whether this is a problem with the raw file in particular (camera fault) or a software issue is to host the raw file and give us a link to download it. If it's the raw file at fault, I should be able to replicate it here. If not, then at least you know it's a software issue there and not an intermittent camera fault.

You can host a raw file by using something like speedy share

Dropped your file into Lightroom ( ver 5.5) interesting series of events. Initial ingest everything looked fine with the image looking, however as soon as the preview had been built, the image changed to the green you had been seeing.

Now the initial image is the embedded JPEG but the preview is based on the RAW data. I would suspect that this image file has been corrupted in some way.

The histogram looks wird as well ( well you probably would expect that)

Going to the HSL tab in Lightroom, and using the selection tool to locate the green caste, and then reducing the saturation, shows that the green and aqua colour channels are affected. Reducing these to zero leaves a mono image. There appears to be no red or blue data in the image.

Green colour cast in Adobe RAW (either LR or PS CC 2014).

If i open the file in ACDsee (similar to Faststone) then it opens fine and the colours are correct but i assume it to is using the encoded JPG.
 
Interesting - so it seems that it is either a temporary glitch in the camera (and that means very temporary), or slight corruption on transfer to the PC.

Recently I have been using cable from camera to pc.

Or it could be a faulty CF card.

I think this weekend I'm going to try a different CF card, initially transfer by cable and then if I see a problem redo the transfer using a card reader.

If still faulty it would then suggest a warranty repair might be needed :(
 
Yes ACDsee exported a tweaked version of the image fine.

One thing it does say when it opens it for edit is the file is a 16bit image and will be exported as an 8bit jpg, png etc.
 
File Juicer will do it for you. I've pulled a 1Mb out of the file. Drop me a PM with your email and I'll post you a DropBox link
 
Just found a piece of software called Instant Jpeg from RAW (http://instant-jpeg-from-raw.software.informer.com/)

Tried it on the offending file and it gave me a JPG 19.2 inches x 12.8 inches 300 pixels/inch

Impressive as it gave me a decent image !!

Thanks everyone for input so far and I will update after my next round of shooting as to what I find out
 
You still need to sort out if this is the camera or an issue with file transfers though. Can you import the suspect raw file via a separate card reader to test if it's still green? If so, then the camera or card has an intermittent fault.
 
Excellent support from Kingston, they have agreed to replace the card, and all I had to do was email a photo of both sides to show it was a genuine product.

An issue had been identified in which the flash cells have been written to excessively (not by the user), thus shortening the life cycle of the NAND Flash chips.
They have re-designed the firmware of the cards, although it was not the cards that were faulty but it would seem some programming setup of them

They feel from my description that this is what caused the problem
