A filtered feather

Most reasonably priced OM-lenses have the same filter size 49mm. I have brought my lenses with this in mind. This was taken with 135mm f:3,5 with probably a red filter if i recall correctly. I have all the basic filters for black and white photography but i rarely use them and like this i cant recall what was filter in front of the lens. Lesson for next time TAKE NOTES!
