A brilliant (and cheap) image stabilizer
When I leave in a rush and forget to put the gorilla in my photo bag, this solution can be really handy to get that spectacular photo with our not-so-steady hands and on those circumstances where it is not possible to use a tripod (or simply we don´t have it). It´s worth noting that this hack is effective with the up and down vibration, but not so much for the lateral one. If you have a video camera, this alternative can be useful, too, but it´s a lot bulkier…
