Can anyone help…….pleeeeeesss!
I had been using my Canon EOS300D with some photoflood lamps to take photos of models.
So the White Balance was set to Tungsten.
I then went on an aviation trip to Ukraine – so I re-set the White Balance back to AWB.
Some of the Ukraine pics – and ALL my Kemble pics from last weekend – taken with the 300D have a blue tint to them.
After much head scratching, I have finally found the answer……
In Full Auto mode, the White Balance was set to AWB, but in Program AE mode it was still set to Tungsten.
I had just assumed that the AWB setting applied across the whole metering mode range – when it obviously doesn’t – Doh !! 😮
Lesson Learned – check the settings carefully in future.
In the meantime – can anyone help with those blue-tinted photos ??
How best to ‘untint’ them ?? – I have used Gamma Correction in Paint Shop Pro – reducing the blue saturation.
This helps a bit, but they still aren’t right.
Does anyone know of a (reasonably) easy way to ‘un-Tungsten’ them ???
Cheers
Ken
PS – Two photos attached – the first one is ‘normal’ – taken in Full Auto/AWB, the second I must have taken in Program AE/Tungsten
How can I recover ????

No, Paintshop Pro.
I removed the colour cast using a colour balance and since I still wasn’t happy, I re-did the white balance on a white point on the highlights on the rear fuselage and a black point from the front tyre.
I could play all day on that, its so much fun. 😀

Using Picassa, the free photo tool from Google this took about 15 seconds

The so-called 90% method of Eddie Zapp might work for you. It is explained on this site http://www.photoworkshop.com/registered/softwarecinema/Eddie_Tapp/index2.html
To be able to use this method you’ll need one of the full Photoshop versions (I’ve tried it with PS 7 and CS2).

This was done with the quick ‘correct colour cast’ tool in Photoshop Elements 1, using the grey of the lower fuselage as a reference point.

If you shoot in raw you have full control ove WB in the converter.
Nope, that still won’t help now….. :rolleyes:

Curves in photo shop on the white, then levels and pick the grey on the pavement. And then in colour adjustment remove some blue.
This was very quick, so is a bit rough and it needs to be done of the large files.
