my whites are too bright

[scottkb]

Shooting daytime football with white jerseys. The whites are almost flouresent purple. What causes this and how can I fix it?

[cphoniball]

Could you post an example of this please?

There are several things that might do this, anything from white balance to overexposure to purple fringing (a lens characteristic which can be improved to a point by stopping down).

there is a purple hue around this one

[scottkb]

this one has a blue to purplish hue

It's called "sensor bloom". It is a characteristic of some CCD sensors (not CMOS sensors) when you've seriously overexposed. It's caused by spillage from overloaded sensor sites into neighboring sensor sites.

The solution is to reduce the exposure.

What kind of camera?

Purple fringe is something that happens on blown highlights. If you can avoid shooting things backlit, and blowing the highlights, that will help. In post-processing, you can desaturate just the magenta (with a mask if there's a lot of other purple stuff in the shot), to help reduce the effect.

Cannon Rebel T1i through a Tamron 75-300.

I shoot alot of daytime games and just recently was asked to start shooting up to 2 night games a week for my son's highschool.

It's great fun, but I sure could use any help and tips.

Thanks

Okay, if it's the T1i that's not sensor bloom. CMOS sensors don't exhibit sensor bloom.

Is that the entire photo, or just a crop? If a crop, what part of the original photo (center, upper left, etc?)

[scottkb]

It is the center of the orginal.

I have some similar stuff going on now and then, I think its from overexposure also like Inkista said. I see it the most when I am shooting into lights so you get some 'hot' reflections on helmets and things. I am using an XTI and a canon 70-200.

here is example of where i have same issue, but mostly around reflections.
might have to click picture and look at larger to see it more clearly, but its around the helmets really bad.
