Yesterday, I took a lot of pond-ice photos. One in particular struck me as being a possible background. Feel free to use these if you wish. These are all sized to 3,000 pixels wide. I have larger versions if interested.
More or less the original as is and also blurred below. Note the original has a patch of orange (a weed under the ice) that was cloned out in some of the other versions.
Random color changes with blurred versions. I opened then in ACR and change temperature and tint...randomly.
