Hi all ! Hope nobody minds that i am stating this thread not in order to take photos but for drawing. I recently started giving drawing lessons at my house and i don't like the current lighting because the shadows aren't dark enough due to the fact that i don't get very strong lighting from my ceiling lamp. The thing is i don't want extra powerful bulbs on my ceiling lamp that will burn all week, therefore i am looking to put another source of light for these drawing sessions - a fixed one or maybe on a stand to be able to move it around. SO... i am looking for a light source that will give me high contrast (dark shadows) and well defined shadow contours. I guess i need a small and powerful light source that i can place pretty far from the subject. I also need it to be able to run 5 hours straight, without heating up the room and preferably without a noisy fan attached to it. I made some tests with one of these (lamp with 35W flourescent bulb). It gave a more powerful light (darker shadows, could be better though) but fluffy contours. Bare in mind that i also don't want 2 sets of separate shades, but i also need to provide light on the drawing boards of the students, so either i have 1 source of light that does enough for both the subject to be drawn as well for the drawing boards of the students, or i have one light for the subject and some kind of diffuse light for the drawing boards. I also don't mind having multiple light sources that are close one to the other so i get multiple shadows that overlap 80-90%, but again, i want the contours to be sharp. Any ideas? Thanks a lot for your time!
