It's not my white balance!!!
Jan 18, 2019 01:30:41 #
The walls in my living quarters are yellow, but all the pictures I take with my Sony a7iii show the walls much yellower than they are. I've been trying all different white balances in the camera except creating a custom one. The colors can be fixed in pp but it bugs me that they are so off SOOC.
So, I was outside taking some pictures when the sky was a beautiful blue. When I imported them, I discovered all kinds of spots in the sky. I always clean the lens before I go out on a shoot, so I was quite surprised. I cleaned all the glass surfaces and took some pictures of the wall to see if the spots were gone. I took some with the UV filter on and some with it off.
The spots are gone AND the walls are the right color with the UV filter OFF. The lens is the 24-70/4. I will try this same experiment with my other lenses and with my Nikon D500.
Can the UV filter really be the cause of such a color shift? Both pictures are the same exposure (F/4, 1/15, 1600 ISO).

Yes, some can. Most do not, in my experience. Stronger haze filters may have a yellow cast.

What brand of filter are you using?

Quit shooting vivid, go to standard.

I never use a UV filter. When I feel the need, I use a clear filter. You should be able to clear up the tint in post processing.

A couple of points. If you are using a UV filter just to protect your lens a (good quality) clear filter would be better.
The spots on your image would be so far out of focus if they were on your lens (or filter) they wouldn’t appear as spots.
I only clean my lenses when I feel that it is really necessary, as, unless you are very careful, more permanent damage can be done.

Yes the filter can create color shift but light can change the outcome too. Or if the camera position is changed lightly....

If there is any LED or other cycling type of light (fluorescent, etc), then the cycling will produce color shifts as well, but not likely at shutter speeds slower than 1/125
All filters can introduce a color shift - it can be very slight, or more pronounced. A UV filter on a digital camera adds a second round of UV filtration, since sensors are already protected from UV light.
If you shoot raw, then there will be no issue, since you can completely adjust color balance without impact, unlike bit mapped files which have already had the color balance set and some color data discarded.

Oh crap, I forgot I had it in Vivid! Thank you.

It is a ProMaster mid-grade. That’s the brand my local camera store sells.

Yes, I can fix it in post. It’s more of a problem with anything in the yellow range. Blues and greens seem OK.

I’m glad I was able to help, did the same thing once. All my pictures were having a greenish and yellow tint. I now stay away from vivid.🤪👏

I thought UV filters WERE clear. What is the difference in a clear filter? One less coating? I didn’t know there was such a thing. The camera store always pushes a UV filter every time I buy a lens (of course they do).
The REASON that I started using these filters is because once I dropped a camera, lens down on the cement. I had already taken the hood off and hadn’t put the lens cap back on yet, two things that I mostly do now AND I keep the strap slung over my head and shoulder. FWIW, the lens was fine but the filter was shattered.
I may have to rethink my strategy.
Yes, it is easy to fix in post.

So the spots are on the sensor? I just used a bulb blower on the sensor. I use lens wipes on my glass.

Doesn’t need filter, had camera on vivid. Gives everything a greenish and yellow cast.😂🤪👏
