I do know what you mean. I have a lot, and I mean a lot of pictures so far of things that are around the house. And that includes landscapes from the window.
Part of it is fun because I'm learning to look at the ordinary stuff a little differently. Part of it drives me up a wall because I want to do something other than just take pictures of whatever I can find in the house that I haven't photographed yet. And then I get stuck in the same rut of taking similar types of photos of different objects.
So to try to break the pattern this week I designated it Lensbaby week for me. I can't take the same kind of shots with the Lensbaby as I do the rest of the time, so it's a way to break my pattern. I'm hoping that it will not only break the pattern but also get a lens that was gathering dust some use. So I figure maybe when I get stuck I'll pick a lens or technique for a week just to break out of the pattern.
