the exposure is very long, gives it a fuller colour. i'm using primary colours, often and alot. And I shoot at golden hour right at sunset the light is coming across This has the effect of highlighting essential tones and shapes filtering out extraneous or unwanted detail. It is a method of simplifying a scene. I am looking to simplify my images as much as possible by isolating the subjects against uncluttered clear backdrops while at the same time retaining a sense of the environment in which I found them.
alternatively, if you use a fast shutter speed like on a smart phone, you will get a crisp sharp photographic looking photo. long exposure takes out the sharpness and brings in a painterly somewhat saturated look.
