Last week talking about the cover for Killing Time - Horror E-Rag™ Issue 1-1 I mentioned about the lamp in the picture. This lamp and much of the positioning of furniture was borrowed from a previous image that I was working on. The lamp has three lights in it in DazStudio. There is a point light to light up the interior of the lamp and acts like the light at the centre of the light bulb. There is a spot light pointing down which casts the shadow of the lower part of the lamp and lights up part of the floor beneath the lamp and cabinet it sits upon. What is not apparent in the Killing Time cover is that there is a third lamp pointing up from the lamp to cast light upon the wall. That third upward pointing light is the most difficult light to fix in the scene and I had yet to place it correctly.
When a lamp sits next to a wall the light falls on the wall above the lamp much brighter than beside the lamp. Due of the closeness of the opening in the top of the lamp to the wall the light on the wall is even brighter than that cast upon the cabinet. The light coming up out of the lamp hits the wall slightly above the lamp, centred on and as wide as the opening. To create the light emanating from this lamp with three Daz lights centred on the same spot, the spot where the light bulb would be in the lamp, should be the way to go. This is not the case however. From different angles the light changes in an unnatural way. As previously discussed in this blog verisimilitude is your friend here, not real world accuracy. This means changing the lights depending on where you point the camera.
