The other day I was shooting a macro image of a rusty bolt and washer that I found in the desert and was some distance from my vehicle. While setting up the image I knew I needed to add some fill to subject and I did not want to walk back to the car to get a fill disk. I thought what do I have on me that would work? I thought there must be something in my wallet that I could use. I found several cards that would work. I was able to use small stones to hold the card in place.
