A DD! Who'd a thunk that
An unbelievable amount of gratitude goes to Kaz D for the feature/nomination/whatever it takes to get a DD, and thanks to everyone else for all the views, faves and comments.
For those of you that are asking how I did this:
I drew the lines with a small pen torch while the shutter was held open using the bulb setting, in a darkened room. Before I started I set the camera to ISO-100 and f/16 and then I screwed off the head of the torch so that the bulb was naked. And then the experimenting began......
Thanks for your time.
