Hi, I am wondering if anyone here knows how to proceed when painting purely from imagination? I am very interested in old aircrafts and ships, and I would like to paint an oil painting of an aircraft or an ocean liner, without using a photograpy as a reference. However, I don't understand how it is possible to correctly determine highlights and reflections on the aircraft (from the ground and sky), reflections from the water on to a ships hull, or to determine the correct values, without any reference material. Many pictures were painted of aircrafts and steamships before the introduction of the color-photography, and yet the artists were able to put in the right colors, and the right values, and get a realistic painting.
Would be happy to hear your thoughts on this.
