Dust Bunnies...lol Yeah. I have not had the confidence to start touching the sensor until i know what i am doing.
Maybe a bit of PS work was involved

.
Trying to learn the fundamentals of IR, i used the help of PS to finish off the effect. Using the histogram is still new to me as being a bit old school and prefer Bronica ECTL 6x6 neg as i know where i stand unlike the new digital tech, but i will not give up trying to push my camera to do the same as i could with the old 35mm.
All the advice give so far will be tried out this weekend at the same location i took the photo of the tree. Thanks again guys for tips...
