Day 53 – White balance

Today on my facebook feed was an article all about “White Balance” and I have used that as my inspiration to experiment with a pot of Primroses recently given to me by a friend. I took two photos today – one of the white balance cards I own in front of the primroses and one of the white primroses in a pu on my dining table, lit only with window light.

I took the image in raw with my canon 100mm lens, IS0 100, F2.8 for a nice shallow depth of field, and at 0.3sec exposure. I then look the image into Lightroom, created virtual copies of the image and changed the white balance on each photo.

These are my results.

My “As Shot” setting was similar to Auto… but was selected by the camera.
The most accurate – I am not sure… these are my white balance cards – they came from here. I used the grey card – the bottom one to select the White Balance for my final shot.

Final image: The tent is halfway between cloudy/shady and daylight – which would makes sense, natural light shining in through the window on a cloudy overcast day. The temperature of the light is halfway between flash/daylight temperature and cloudy.  In this case the “Auto” setting most accurately represents the colours of the end image – but it also highlights that if you are reproducing images for a particular reason and need to show off the colours accurately – it is essential to get the white balance settings right.

I think I may have a go at using my white balance cards more often 🙂
