Under chin Ghost?

Hi guys,

Was up at my granny's house with my brother on the weekend and got some ok shots of my nephew's with her. Can anyone explain what the discoloration is around my grandma's chin and on both nephew's shoulders? Is this caused by her glasses or have I set something up wrong? Thanks in advance.

Did they have spaghetti hoops for lunch?
You can see some of my photos here if you are so inclined

I can't see any discolouration where you describe. How are you viewing it?
Possibility your monitor is set too bright or dark or contrasty (not sure what you're actually seeing!)

Beneath my grandmothers chin, on the orange fold of the LHS nephew's tshirt left of the letter G and left of the third button down on the RHS nephew's tshirt there is a blue-ish hue. Would the blinds being open behind cause any kind of issue?

Thanks,

Um, Lincolnshire sausages with roast tates I think...

I think your monitor must be set too bright if you can see that easily. I have to brighten the image quite a bit to be able to see discoloration in the areas you describe.

My bet is that it's a bit of lens or filter flare, caused by shooting directly into the light from the blinds.

Thanks Andrew & Jak for the brightness suggestion. I have turned my monitors brightness all the way down and to me it is still just as visible. Perhaps I'm being overly critical.

To me it looks fine, but if there is a slight colour cast, and I say again I cannot see it, it could be due to mixed lighting sources (not sauces as those writing above would have us believe!)
The only oddity with the picture I'd query is why you dialled in half a stop under exposure as when shooting with backlight you'd normally need to dial in more exposure to compensate. That has made the subject slightly dark and maybe what you're seeing.

If you brighten the image quite a bit, it is fairly obvious. The levels on this crop look about right on my monitor - and I can easily see the blue discoloration, below and to the left of the lowest button on the lads grey jumper.

If that were to happen on all frames taken it could be a slight sensor stain but if just this image it's barely noticeable even now to me. I guess a thumb print on the lens could affect the image colour slightly, especially in a contre-jour image. Or it could be a reflection within the lens of the light from the window. I feel its not really worth worrying about unless all images are affected. Just check the lens is clean (with a lens tissue or cleaning cloth, not a handkerchief) and double check some other recent images to see if you can see it on those too just to eliminate a sensor issue.

If it is just on this photo, that would be my guess too.

The spacing looks to me as if it matches the blinds fairly closely. I'd certainly expect it to be lens flare from the window.

FWIW I could see it straight away on your grandmother, but can't spot it at all on either of the boys.

Thanks for your input John, my brother (and the nephews photographed) actually live in Hainault. Small world, hey? I'm a massive novice when it comes to shooting, I would suggest that the dialing in of under exposure was either a) me messing about, or b) left over from last time I shot. Appreciate your advice on shooting with backlight, this is what I'm here for.

Petro / John / Andrew the staining (this seems the best word for it) appeared on a few photographs taken in a similar position, having noted Petro's comments about the spacing with the blinds I think I agree and this makes sense.

Thanks for everyones input, loving the forum!

Yep, a small world! Hope they didn't get caught in the Hainault tornado last year.

It is very easy to forget you changed things like the exposure compensation previously and puzzle why subsequent shots come out odd. I had a batch of monochrome images once that I wasn't expecting - thought the camera had gone wrong until I realised I'd unknowingly changed the custom image settings! It's easily done.
