Add firefly bokeh effects to your photographs with this collection of 25 shimmering firefly overlays. Images are 5000 x 4000 pixels 300 dpi jpegs. If you are unfamiliar with using non-transparent jpegs as overlays, I provide simple Photoshop instructions for overlaying jpeg images onto your photos. These images can be used with any software that supports layering. Note: not compatible with Lightroom.
