Shooting some pictures indoors this afternoon. Using the D80 with 50mm 1.4D lens. Set on auto-apature and probably wide open or close to most of the time (f1.4 - 2.8). ISO set between 1250 and 1600.

These were right in a row. First picture looks okay, but second has dark haze on right and last has dark haze on left(?). Why?

Hey Daubs,

Your first shot seem to have a little bit of it on the right as well. Are you using a linear polarizer?
And auto aperture? Do you mean Auto mode or Aperture priority?

are you sure thats f1.4 ?? :confused: seems like a very deep DOF. and why iso 1600 ?

Just UV filter to cover my glass. Some of the shots were f1.4, others as high as 2.8. Dimly lit building...was trying to pull in as much light as possible and stop the action (hard to stop kids chasing down Easter Eggs). Kind of like shooting basketball in dimly lit gym. Cranked up ISO, cranked open to f2.8 and larger and tried to get as much light in as possible.

Some shots had no noticible problems.

I did notice the high ISO noise reduction was set to "normal", not "off." Would that make difference?

Take the UV filter off, it appears to be playing tricks with the lighting. Something might be wrong with the coating on the filter.

Take some shots with it off and on and compare. There is definatly something wrong in those pictures.

Just curious, what was the WB set to?

that iso is on fire!!!!!!!!
and that looks like 5ish apperture to me.
what jcon said take the filter off otherwis ei dont know that looks crazy with that tone.
and one questions
you have a truck indoors?

White balance on auto. Like to jack up the ISO so I can get faster shutter speeds and stop the action / reduce blur. Kids don't like to stop for pictures while chasing down them eggs.

The building is a large storage building (steel shed, morton building, whatever you want to call it). Indoor storage for RV's boats, etc. We were going to do the Easter Egg hunt outdoors, but 20 degrees and nasty winds here in NE and the ladies said, "let's go indoors for this one."

Probably 90-95% of the photos don't have that funny haze on them. Could this be the High ISO NR? Had it set to "normal" while taking these pics.

Take the white balance off of Auto and remove the UV filter. Something is causing a color shift in all three pics it's just more pronounced in the latter two.

I think what you are seeing is the cycling of the lights at this particular venue. sports photographers see it alot shooting in gymnasiums. . . With a SS fast enough to freeze action you'll freeze the phases of a normal Fluorescent cycle and notice differences in brightness and color -

have a look to see if this could be what happened to you:

You can also take photos at home if you own a fluorescent lamp and take note how longer SSs will render a more even image and how the faster SSs will freeze the light cycles and cause color variations.

Interesting aparmley, can't say I would have ever thought of that. thnkz ;)

The examples the OP uploaded appear to have been taken outside, so not sure that fluorescent lights did this. Although the OP is a bit confusing as to if they were actually inside or out.

From the pictures, it looks like outside.

More samples from different situations would help.

Yes, the photos were shot indoors...in storage building. I believe they are fl-lights...and that makes complete sense about catching them in mid cycle. I've never seen haze like that from my D80 before or since. And it's interesting that some of the photos had the haze, others did not. I think I only saw the haze on the portrait shots, not the landscapes.

I've seen a similar, but not identical, effect when shooting hockey. Most frames come out OK, but maybe 1 in 10 have a pinkish hue as if the white balance is off.

I spoke to a local newspaper photographer about it, and he said it was the sodium-vapor lamps "pulsing". We didn't really discuss the physics of it, or the electrical frequencies involved, so I don't know what he based that on.

But I do know that in every other aspect of shooting he seems to know what he's talking about...

We have those vapor light fixtures in our gym, ugh. You can see the color change from pink to blue to grey or white. If you preset your wb you are out of luck, if you use auto you will be all over the map, best bet is raw so you can adjust later.

I stand corrected. I was way off with my "diagnoses".:o

Glad you found the culprit.
