Exercise 6: Opaque colour mixing

The intention of this exercise: the effects of mixing white with colours to obtain graded tones. Success at last!
This was much easier to do than the previous exercise. The main reason being - that I stumbled across a video on utube, demonstrating how to do a graded wash with opaque paint. Hey presto! The transition is much smoother - without dark bands. Through following these techniques  I was also able to obtain far better results with both transparent and opaque washes on the very first attempt. It did make me wonder how I could have got it so wrong previously despite numerous attempts. The successful technique was: dampen paper, apply full strength paint at the top, working rapidly down the surface using light pressure on brush and working from side to side (the paint strength becomes weaker) to just below the middle. Then work in an upwards direction from the base with a clean damp brush towards the colour and blend in gradually. I used two different brushes. What seemed to make the most difference were: working rapidly down and up the surface and not being afraid to go back over it a little. Also, making sure the paper is adequately damp beforehand. Previously I was working more slowly and painting parallel horizontal lines, perhaps being too careful.

I know these three are still far from perfect but far better when compared to 
most of my earlier efforts in exercise 5

How could both transparent and opaque methods be used together? 
Opaque over transparent enriches the wash.

Transparent over opaque can be used in a composition using glazes to build great depth. An opaque and textured ground used under transparent glaze or glazes increases luminosity and three dimensional effect. Also for modifying colours below, such as the complementaries of blue and orange.
Transparency is useful in a landscape to give the effect of distance. Moving forwards the paint could gradually become more opaque towards the middle and foreground. 
Transparent - to depict water or glass, opaque for solidity ie, trees, walls.
