Thinking and Practice Tutorial 14/10/13
This tutorial we were shown how to correctly white balance a photograph that needs altering. We firstly imported a portrait into Photoshop. We changed the colour settings to Adobe RGB 1998 and loaded the histogram so we could accurately see where the photo needed colour correcting. We created an adjustment layer so that any alterations we make is done on a separate layer (non-destructive) rather than directly editing the image. We selected three parts of the image using the eyedropper tool, light and dark flesh tones and a control tone which was the grey jumper in the image. Looking at the colour properties we concluded that there needs to be 40 – 60 more red units than green, and 25 – 30 more green units than blue. We selected the to flesh tones and looked at the points on the blue scale. We selected an average point between the two points shown on the scale and shifted the point below to alter the colour balance. We then adjusted the red and green in the image to make sure the units were at the correct point.
