Not trying other possible object combinations and merely opting for the first objects that present themselves.
Going for the most orthodox viewpoint without shifting the angle from which the objects can be seen, such as a setting viewed flat-on.
Low visual awareness, consigning various elements to invisibility such as the background, the lighting and the shape of shadows may result in a painting that reflects this view.
Fear that the still life may look silly to othes if trying experimental techniques.
Ideas for Still Life
Try viewing the objects from bizarre angles rather than just eye-level. View them from directly above or from a vantage point below eye level or even below if placed on a glass tabletop. Of course, painting from life may not be possible from such an unorthodox angle, so good quality photos might be necessary.
Try placing objects containing contrasting elements or those in unusual contexts within the composition. A rusty old engine or an animal skull within a setting of fruit could make the viewer see the objects in a new light. Provide contrast in other ways, such as warm colours against cool; rough and smooth, sunlit and shaded. Provide a quirky focal point by placing just one bright-coloured object within a setting of subdued ones, or one point of sunlight within a shaded view, which might fall across a carefully-selected object.
View any object as possible subject matter for a still life, no matter how kitsch. Trawl Ebay, car boots, second-hand shops or house clearances to find truly unique objects or those of yesteryear. A Micky Mouse clock or Rubik’s cube could provide the ideal focal points to an otherwise ordinary still life.
Try out different backgrounds rather than that of one of just one colour. A partly-open curtain; a window revealing a dramatic sky or light filtering through lace could bring the background to the fore. Brick, tiles or embossed wallpaper (or peeling wallpaper) will exhibit interesting textures if obliquely-lit.
Still Life Shadows and Reflections Make unorthodox use of the shadows. Look out for bizarre and weird shadow shapes that may stretch across the table when the light source is shifted around. Bright sunlight filtering through a neighbouring window will often transform the most somber subject matter and bring out bright colours, contrasts and reflected light. Who said the still life had to be completed indoors? Try placing them on a patio table. Lace or lattice material can be used to create a dazzling soupcon of sunlight and shadow over part of the setting will open up the view, otherwise invisible for new compositional possibilities. Unusual patterns over surfaces can be seen if sunlight
A split view of a still life can be exploited if part of it is distorted by a glass tumbler, a brandy glass or bottles. Try partially filling vessels with clear fluid to optimize this effect. Mirrors and other shiny surfaces will open up the view, otherwise invisible for new compositional possibilities. Unusual patterns over surfaces can be seen if sunlight is filtering through lace curtains or an embroidered lampshade.
When looking at a still life painting, or when creating one, the most important thing to ask yourself is, "What does it mean?" Is it a random collection of items, or did the artist have a particular intention when choosing them? It's easy to look at a painting and think, "Hmm, pretty objects", and quickly move on to the next painting. But the artwork usually goes much deeper than just depicting pretty objects. Even if a piece is purportedly meaningless, there is always an underlying thought process behind the work. (And if you want to look at art intelligently, it's important to examine the artwork with an investigative eye and an inquisitive mind!) The themes for a still life painting can be personal, cultural, societal, mythological, religious or philosophical and existential. Or, they can be based on material qualities, such as color or texture. They can even be whimsically based on objects that start with the same letter of the alphabet, or things you might find in a typical junk drawer in someone's kitchen. And of course, all of these themes can overlap to weave a richly layered tapestry of theme and meaning within a single artwork!
