I belong to a Meetup group here in Ohio that is a great bunch of photographers with all levels of skill and all kinds of equipment. We meet each month with a different topic to discuss and possibly shoot. This last weekend the topic was macro photography. You know THAT caught my eye. There were several stations with various props and ways to do it. There were bellows, magnifying rings, soft boxes, extension tubes and ring lights; so tempted to get one of those!
We experimented with water drop photos, toys, mirrors, flowers, bugs (not living ones) and this thing here. Not quite sure what you call it but it was so colorful that I gravitated right to it.
