Help, my images have gone all pink and I don't know why. Samples below, with full exif in tact. All ere shot saturday morning and I don't remember the first one looking like that through the viewfinder. As you can see, the 'tint' progressively clears as the morning goes on. However, ALL shots were shot with the same equipment/filters/lens/etc.

The likely culprit is my new circular polarizer, but I don't know why, and what, if anything, I was doing wrong. :(

I didn't buy a cheap one and it is a 105mm screw in heliopan slim on the front of my Lee holder. This is the first time I've used a CPL and I wasnt sure what to expect. TBH, there didnt seem much difference, but I put that down to it being a dull morning with crap light. So, any suggestions/help?

Oh... white balance... this was on auto. However, it made little difference to #1 adjusting it afterwards in ACR. Just meant that instead of the all-over pinky cast, I could get an all-over orange or blue cast depending on whether I raised or lowered the temp.

Heeeeeeelp!
 
Can't help you with the colour. A polariser will only do something noticeable when the sun is to the right or left of you. When the sun is in front, behind or overhead it will do next to nothing.

Maybe take a picture of a grey card to get the white balance from?
 
I haven't got a clue what went wrong but you could rescue them using the remove colour cast tool in PS Elements

quick bodge :D

The last one looks okay, you sure it wasn't your brains WB correcting and actually it was very pink.... I've seem this myself with shots with particular low cast light. I had a shot that was so red I thought I'd messed up the WB settings but eventually decided it was actually that red on the day, I'd just not noticed at the time.
 
Lee,

You're certainly not the first person to have this problem using filters on a 5D and I'm almost positive that moving away from ISO 800 (and 640 /1000) will get rid of it. The problem is likely to occur with CPL's or ND's (or any other filter that effectively reduces the light by a stop or more).
I can't offer a definitive reason why it happens and have read several theories (un-substanciated). The one I personally think is the most likely is that light in the IR part of the spectrum produces moire patterns.
There's a blog site here where someone is experiencing the same problem and has posted examples... http://mycanoneos5d.blogspot.com/2008/07/hitech-nd30-test-take-2.html

If shooting in RAW, are you using the same converter (such as Adobe Camera RAW) as you have always used?

I have had trouble with converters over-emphasising magenta, which looks like what's happened here.

Or are these photos just really nostalgic? :lol:
 
Cheers for the input guys :)

If you take the filters off do you still get the tint?

I don't know, as I only noticed it once home. And as I say, it progressively clears through the morning from pic one (pink) through to pic three (normal).

I don't think so... but couldn't say 100%. Am sure I would have noticed though, and I remember being really effed off that everything was so flat, white and bland.

Phew, that's reassuring. ISO 800 was an error... I forgot to change it. So, hopefully it won't be a problem moving forward then. :) Will do some tests next time I am out trying different ISO and see what that does. The strange thing though is that I left the CPL on all morning as it was new and I was keen to see how/what it did.

Will take a look at that blog tonite. :thumbs:

Shot RAW and imported into PS CS3 through ACR plugin exactly as I always have. :shrug:
 
No help at all but it looks like dawn to me, I like them with a pink cast. :lol:
 
As others have said they were taken fairly early-ish in the morning, it might just be the natural red sky at morning effect.
I'd try the same filters/exposure with a grey card or under controled lighting, see if you can reproduce the problem, if you can it should be simple enough to find it by a process of elimination.
Auto colour in PS seems to fix the ones you have there easy enough. Wayne
 
I've had the same problem when stacking lee filters. It seems to confuse the white balance of the camera a little so you get a slightly pinkish tint to things. Can look quite nice to my eyes.

The only way I have found to correct is with CaptureNX (no good to you I know) but the WB adjuster in that has an eye dropper so you can pick a neutral grey to set the WB. Then you can adjust the levels of blue and red as needed from that. Works quite well IIRC.

Another point of note is that under dim lighting your eyes see things differently to the camera. Whereas during the day (and I'm not sure if I have this the right way round btw) the cones on your retina are most active and deal with the image gathering and are sensitive to colour, as the light levels drop the rod cells kick in. These are only really sensitive to levels of brightness so you see things more as shades of grey. Hence why, when you do long exposures at night, you get lovely colours in the sky etc that your eye doesn't see!
