Cheap flash bounce
DIY flash bounce, I used the template from this tutorial
Just printed out the template and cut the foam thing to shape and glued the wide flexible band to it with contact adhesive to keep it in shape and for easy attaching to the flash. It took about 15-20 minutes to do and most of it went to waiting the glue to dry.
The second picture is just to show how small it goes for the camera bag. Total cost was less than 1€ so it was very much worth it and it works great.
