Hello all,
It was the first show for the 20D yesterday and I have a question for the experienced snappers.
Look below:
shot 1 – I was in ‘amateur mode’ with the camera set on ‘sports’ to get a constant autofocus, you can see that the shutter speed was too high (frozen props)

so for shot 2 I tried 300th sec to keep some prop movement, but the shots came out with a very blue cast:

anyone know why this happens? I thought that in ‘spaz’ mode – if I used shutter priority, the camera would take care of the rest…?
Is there a way to use the sports mode focussing but a lower shutter speed and avoid the blue cast? Or is there a way to use the lower speed and again, avoid the blue cast?
I was quite pleased with this one:

but this one was in sports mode, as there was no frozen prop issues to worry about…
snappers – advice gladly received!
thanks, Zwit 🙂

I have read the relevant part of the manual, re-set everything and taken some test shots outside of various light aircraft going over, seems all sorted now! 🙂
thanks so much, all of you, for your help!
On with the season!! 😀

You need it in AI servo focussing when you’re shooting in Tv, or any other mode. Not sure how to do it on the 20D – read the manual.
You should be able to set Auto White Balance in Tv mode. Again, consult the manual.

that sounds like it may be the answer, as the last thing I did before the weekend was some indoor product shots using the tungsten wb setting…
hmm… thanks guys – it’s starting to make sense now 🙂

Manually adjusting the white balance is only possible with the main dial set to P, Tv, Av, etc. – ie that side of the green square. In Sports mode, etc. the camera ignores the manual setting and uses Auto White Balance instead so the colours could be wrong in Tv mode (where it uses the user’s White Balance choice) and right in Sports (where it uses AWB). The camera remembers settings so, if it hasn’t been changed since, turning the main dial to P or similar will tell you what WB the camera was using.

I agree. It looks as if the White balance is selected on the wrong setting. I think on Sports Mode it is set to AWB (Auto) but on any of the manual settings retains the last used setting. Make sure it is not set to indoor lighting or something similar. The camera shouldn’t make it this far out if it was on auto.
Hope this helps.

thanks guys 🙂
TonyA – it was ok again when I switched back to sports mode, so I don’t think anything else changed when I changed autofocus modes. The tornado shot was after the hurricane for example.
but yes these were straight from the camera (apart from cropping)
I don’t mind twaeking in Photoshop, but i’d like to get it right ‘on the day’ 😀
~Thanks again chaps!

I think the white balance is wrong in the second picture. The camera should not get the colour that far off on its own and, in any case, the colours in the image should not be changed simply by changing shooting mode.
I suspect you changed autofocus mode and accidentally turned the dial on the back of the camera at the same time – this would change the cameras colour balance setting

You could always tweak it in Photoshop, since it looks like you’ve taken the image straight from the camera.
I just levelled the picture and got rid of the blue cast – which is the skys reflection as much as the camera being intimidated by the dominance of blue in the picture – instantly, but just about any imaging programme should help out there.
