The last two exercises I explored different ways of rendering a three-dimensional perception of form. I learned how important it is to understand correctly the direction of direct and reflected light. Referring to Leonardo da Vinci’s five-value rule helped me to understand the concept deeper. My initial sketches supported my learnings. What I found out is the importance of good observation of real objects in front of me. When I compared what I observed with my naked eyes with the photographs I took from the set-up, I was quite astonished how bad the photograph is able to capture the fine value gradations. This I saw in both exercises and I am glad that I did not need to rely on photographs for my drawings. Those I took for my log reference.
Further I found out how complex the situation gets when color play a role (as in normal life). E.g. in exercise 2 in my first composition, the reflected light from the apple on the bottle was so colorful and nicely to be seen. Whereas in exercise 3, it was not that obvious, many overlapping shadows and a darker colored underground (book) closer in color to the cast shadows. What helped me here again, was understanding the concept and to practice.
Also I find it useful to distinguish between reflected light and reflection: the first where light is bouncing back from a surface, the other where a surface acts like a mirror reflecting an image. During my exercises I was more concerned about reflected light, but I also faced in exercise 3 the effect of reflection ( image of lemon in the shiny cup).
During the exercises I got really involved in the value gradations detection, so that the form as such became somehow secondary. That was true especially in exercise 2. Whereas in exercise 3 my focus was on line drawing that took me back to the form of the objects. I tried to follow the contour of the objects with my marks. I believe that this is the reason I got a bit stucked. During the second run in exercise 3 I was deeper looking at the values and tones, also from a distant perspective.
Overall, I think exercise 2 was easier for me to ‘forget’ the form for the sake of value. However, avoiding outlines in exercise 3 was quite helpful to focus more on tone.
– Form become the focus when looking at contour or outlines
– Tone become the focus when looking at light and shadow in a kind of dialogue
I will take this into account in my further studies.
