The Colour of Light: Judging colour temperature 2

Take a similar situation to the last one and shoot three kinds of picture but vary the WB setting 3 times so you end up taking 9 images.  Compare and say which you prefer.

I prefer the AUTO on the first set and the last but he daylight in the middle set.  I think the camera does a good job of WB actually although in the past I have felt it was a bit yellow and green at times, but perhaps that was to do with some sort of colour cast.  The difference between daylight and AUTO is negligible in some images but the ones of my son at the end it is more marked.  Incidentally, I hope my mother will forgive me for using such a wide angle to take these but I am very pleased to finally be getting on with these exercises as I stalled slightly for a bit.

WB Shade f4 ISO 200 1/120s

The Colour of Light

Find a subject you can move around and does not have a strong colour (face for instance), in clear weather (oh dear...) take three photographs at different times of day; one in full sunlight during the middle of the day, one in shade at the middle of the day, one in sunlight when the sun is close to the horizon.

Make sure WB is set to daylight rather than AWB.

The following two images are quite similar because despite waiting for a sunny day the winter sun is pretty weak weak and watery.  It's not the brilliant blue sky I need to demonstrate the difference in light as things stand - if such a day ever arrives in time I will replace photo No 1.  Both are pretty yellow actually.  Very low sunlight to be confirmed.
