In his e-book, Coloration in Sketching and Rendering, Arthur Guptill says this examine of a white porcelain cup lit by direct mild “presents a perfect transitional topic, because it combines curved and flat surfaces.”

“It’s fascinating to check the gradual adjustments within the lighting from Aircraft 1, which, going through the sunshine instantly, was virtually white, to Aircraft 4, comparatively a lot darker. Aircraft 5 was about the identical in worth as 2, receiving roughly as a lot mild. Objects like this, exhibiting a succession of planes, train us that surfaces deepen in tone proportionately as they obtain much less mild. Rounded objects typically present this too.” 

“This object differed from our earlier ones within the high quality of floor, for it was glazed. On the level market ‘lightest mild’ it mirrored a miniature a miniature picture of the window far brighter that white paper may categorical. Many minor reflections have been evident, too a few of which we have now proven. You should search for such reflections when drawing easy objects. Whereas it’s neither doable nor essential to signify each slight variation in tone, the final character have to be expressed.”
