Sigma 24-70 2.8 Question??
Dec 22, 2016 08:29:51 #
Recently bought a new Sigma 24-70 2.8 DG HSM EX for my Canon 7DMii to do some portraits & school yearbook work. But it has been a bit disappointing. It puts a weird orange or blue color cast on my pictures. I was wondering if that is something I can fix in my camera settings, (white balance etc...) or in Post. I am not very good at post processing, and only have elements 14. -- Or if I should sell that thing on ebay????? Thanks for your time
Notice how the girls below look a little orange - the one looks like an Oompa Loompa !!!! It's slight - but it's driving me crazy

It looks like perhaps a white balance problem- odd color cast from flourescent lights? I don't think a lens itself woud cause extreme color differences.

It looks like you haven't set a proper white balance to accommodate for the indoor lighting. That's likely to explain the skin color being off. This has nothing to do with the lens.

Yes - probably, but it seems like I never have this problem with my other lenses. And when I'm outside it has the weird blue or brown cast. I usually just leave my WB on auto. I guess with this lens I will have to be more careful with that.

It is the white balance. Next time, on the camera, either use AWB (auto white balance), or set the selection manually for the type of light, or use one of the many available color calibration devices. After you set your camera correctly, you can fix this existing photo in PSE either by moving a simple slider (tint/hue) under the color adjustments in the right panel or trying either color auto correction or manual color correction under the enhance pull-down menu.
Edit: after seeing your reply, sounds as if you have the WB set for tungsten when outside, hence the blue cast, and daylight inside, hence the yellow cast. Are you sure the AWB is on and you haven't overridden it with some other custom camera setting?

I would recommend you take some photos as you normally would but use a gray card to set white balance and see if that doesn't correct the color cast.

You have not indicated what camera you have. Personally, I don't have much faith in AWB, at least not on my old camera (I never use it on the current one). Try setting it for the lighting you have.

It does appear that this picture was taken indoors. It's possible that the light is mixed too. It's very difficult for a camera to get the white balance correct when the light is "mixed". In your case, it might be fluorescent light mixed with natural light from a window. Shooting a grey card will help a lot. But the accurate way to get the colors right is Xrite's ColorChecker Passport. It's a calibration tool that you take a picture of, in the light you are going to be taking pictures of using the same lens you plan to use. Then you make corrections via a plugin that works with Adobe products.

I use a Sony Alpha 7II and mostly Sigma lenses. I have not experienced any color balance problems but I did have a similar experience shooting indoors when the lighting was "mixed" but I have no solutions except a little bit of post effort.

Looks like fluorescent light. You might what to take a look at this:

White balance, white balance, white balance. Figured I would say it again just in case you didn't get it the first million times.

Great thanks - I will fiddle with that. I usually just leave it on auto, but under the fluorescent lights I guess I better get more involved.

I have the same lens but use it on a Nikon d7100. It is the best and most versatile lens in my bag. Suggest you learn as much as possible about your camera settings. It's likely a white balance problem. I usually use Auto White Balance.
