Start by playing with your shutter, and keep it open as long as you possibly can. (look it up if you aren't sure how to use it).
A tripod is going to be your bff for this assessment. We will look at these when you come home from break- here is an example:
Dial in an exposure long enough for you to complete the word or image, and start the release with the self-timer. Get in front of the lens and start drawing. To finish the image hold the torch steady and turn it off, then move out of the frame. Check the LCD for results and amend the shutter speed as required. It’s advisable to wear black so you do not show up within the photo and remember to move quickly or you’ll be captured within the scene. Coloured gels or coloured plastic sweet wrappers can be taped over the end of the torch to add a variation of colour.
