Are these raven shots taken recently John?
Again quite a bit of green color cast.

Thanks all
Yes -taken two days ago,
These pics are processed and taken exactly the same as everything I have posted on here over the years so it must be a combination of late afternoon sunlight and fresh grass , with the black/blue colour of corvids. I can take the green out no problem but
the birds will not be accurate. If the birds are green it must be reflecting off the grass in the bright light. Why is it just these two latest shots and not my other stuff ? Every thing else would be out surely ?
Doesn't make sense to me.
Maybe I need a new camera

Really green looking John. What abut your WB setting?
Could this have caused your issue?
Im green with envy John , not just one raven but two. The phesant looks fine.

Don't want to make this a long drawn out thread but just found the camera- or one of them on Hue setting -3 ! - what ever that means !
What worries me is that I have been using the same old settings for years . Don't know how it got changed.
Ian - No I never use auto - the results are even worse I reckon. Sometimes I have it on flash setting and forget to re sett it but not this time. Fed up with this bloody digital stuff . I'm off out to get some film tomorrow !! The point is,that if I can't see that an image has a green cast which every one else can see then there's not much point in carrying on is there?
Cheers
JR
Ps What about monochrome ?

Are you referring to the pheasant shot ?
Taken on a different camera maybe ? Who knows ?
Cheers

If you look at the dead grass in the first raven shot it looks about right, in the second adjusted shot it now looks too red and in the pheasant shot taken shortly after it looks about right. So for me the original shot reflects the light conditions more accurately but the white balance does look slightly strange like an old scanned slide.
John - just try setting the black point and not introduce a general colour adjustment - the dark pupil of the eye is what I usually calibrate from - the pupil should be near black no matter what the lighting conditions as its a dark hole. I find getting the the black point sorted usually corrects most White Balance issues. Use the colour dropper tool the darkest part of the eye in the RH bird has RGB values of 0,27,20 indicating a a colour shift at that end of the histogram hence the perceived colour cast.
By adjusting the black point RGB values only to 0,0,0 or therabouts you get a reduced colour cast to the straw coloured dead grass.
John I agree with you that the Ravens' feathers are reflecting the green of the grass but it does look as though the WB slightly is slightly out. I can post an adjustment if you want, but I know you don't always approve of amendments to your posts
I've just read Mike Smiths post and feel totally inadequate. John, I too am sick of this computer nonsense. Digital has improved some things in photography but it has introduced far too many headaches as well (quite literally on occasions when spending time in front of a monitor). The Ravens are great whatever the colour!

Hi John, nice capture of the Ravens. On my screen your images have all a different degree of green in them.

An excellent capture John.

Thanks for all your help and the private E mails. I am having a problem with E mails at the moment but will get around to sorting it.
Just to answer a few points.
It is a new monitor (two months old ), but my other stuff seems ok.
The monitor was set on K6500 and I've altered it to RGB (is that right?)
The camera was on sunlight white balance. The only thing is the hue was on +3 . But then it would have been for a ll the other stuff.
Its ok talking about setting black and white points etc but I can't do it in Paintshop pro.
I do eye drop the whites if there are any just to check for any glaring colour casts and that usually works. Its just this particular day with the sun and the green grass and the blue black birds .
What worries me most is that in all the re posts and those that people have sent - I can't see a lot of difference !!. I am red green CB but then a lot of people are !
Thanks again anyway.

I sympathise with your frustration John because I struggle with colour casts largely as a result of being slightly colour blind. When I do spot them I am never entirely confident that I've removed them.
I must say though that I can see the green cast in the first image, so it's a bit of a mystery how it got there. My own experience of casts is that they are quite unpredictable how they creep into certain shots. Also, they show up more in certain shots and the blacks of the ravens clearly accentuates the cast here. I can't see it in the pheasant shot (but that may be just me).
Anyway, that point aside, it's a very nice shot and unusual to see one sitting like that.

John,just keep posting your excellent pictures.That's the main thing!
If the odd one has a colour cast,I'm sure we'll survive somehow.

John - they are great pictures what ev er the cast or eye or monitor does to them. You worry too much; come on now it doesn't matter a stuff!!
Hi John,
I'm afraid I've no idea as to what may be causing the green cast, but it's definately not colour reflecting off of the grass, the birds would make The Incredible Hulk pale in comparison The repost looks better but the colours are still not right for some reason, i.e. too much green in the dark plumage. I'm sure you'll get to the bottom of it though.
One theory I have over green casts is the sunlight reflecting off the grass. I have taken 1000s of images at horse shows on grass & have sometimes seen a slight tinge of green on peoples faces especially if they are facing the sun.l

Thanks for all your help everyone. Its obvious that others have the same problem at times.
Its the fact that all the corvids have this sheen which has a large element of green in it.
Never mind eh ?

I think it's only your recent posts that look green. Could your monitor be on the blink perhaps?
Great birds though!

So green is my favorit color, so it couldn't be better.
