Hi All,

I have been asked to shoot a local boxing tournament this weekend for the promotor who is a friend of mine, and I am looking for some advise.

I have reviewed a lot of images from similar local events and they have been very poor. Mostly in the colour and exposure front.

The event with be in a local community centre under stage lights on rigging and standard tube ceiling lights which will create a crap colour cast. I already know I am going to be shooting high iso due to the poor light, but what I wanted to ask;

to minimise the amount of post processing to get the images colour & WB right, would you use say a colour passport at the beginning of the shoot as a reference frame, then sync the changes across all other images?

The light should be very consistent throughout, so I am anticipating that I won't see any changes needed in SS or Ap due to light changes, I am just trying to decide the best way to improve the colour and WB in the images for this type of environment.

A custom WB is easy...use a neutral card and set your camera to custom WB and use your reference image.

The colour one is a little trickier but no reason why the passport won't work. Done forget if it is white folk boxing they tend to take on a new shade when exerting themselves so take the changing skin tones into consideration.

Hi Tiler65,

Thank you for your comments, yes a grey card, doh! I forgot that ;-), that would work.

Thanks for the reminder of the skin tones, yes, your right, hot sweaty men go a little red in skin tone, so I will watch out for that.

Whats wrong with using auto white balance?

The problem with auto white balance is that the ceiling lights with be flouresent tubes which will cast an awful colour cast which the auto function may not pick up, so it would be better to use the flouresent white balance in this instance.

But, the problem with setting the white balance to flouresent is that there will be a mix of stage lights too. This will mean that they auto white balance will go crazy trying to find something that works with the different colours of the different light sources. Inevitably it will blow it's top and get it wrong, and probably be different again for each image.

So, the best thing to do under mixed lighting is set the white balance to those conditions using the custom white balance against a grey card, or using LR to correct the WB using the reference image with the grey card and then sync across them all in the library.

I think I understand that.What is a colour passport? also is this just like an average between the different types of lighting?. Thanks.
