When you utilize long term exposure and use 1 light, run around a subject say a cabin and light it and with a flash light. I am poor and this is what it's come to for me to start lighting things. I have had some cool pics done with this technique with just a single light. I have made things look like they have been lit by at least 4-6 different lights. If I could post attachments I would. I have never heard of this and am sure I did not figure it out first. Just wondering what the name of it is so I can start looking at what others have done. Cheers!
