Quicktip! for Lens fog
At certain times of the year lens fog and even ice can be a real problem when photography at night. Of course, this is going to vary depending on where in the world you are located, but here in Japan it is almost all year. I find it is the worst when the camera is left to time lapse the night sky.
The solution is in the video below but first check out the pictures below. The picture on the left was the beginning of a time lapse sequence. 90 minutes I went to check on the camera to find the front of the lens was completely covered in ice. Water had condensed and eventually froze over ruining the sequence.
It can be a real pain in the butt. There is a solution that has worked wonders for me. I use disposable hand warmers. They are the type that you have to shake to activate. You can attach them to the lens a variety of ways but I use the tube part of an old sock. It may not be the coolest looking but at least it wont leave any adhesive on the lens body or scratch anything. If you cannot find the hand warmers in a local shop they are available online.
