This hue of blue sky over a Eucalyptus tree photographed in February obviously indicates this crime could only have been committed at non-other than Boyce Arboretum near Superior, Arizona by an outsider from a city like San Diego.
The photographer would have to come from a place where Eucalyptus is commonplace. He would not expect to find this unusual flora in Arizona. Therefore he would take a picture of it.
The perpetrator is a lone, male photographer aged 45-70. This is indicated because there is no one else pictured in the frame and only middle-aged and older men take pictures of tall trees.
Fess up! You did it, didn't you?
Sherlock (Besides, I think I have photographed that exact tree)
The photo appears just a little too dark to me. I see the connection to "silence" only through the title. Without that, I think the connection is weak.
Lovely tree, if it could only talk! The image is slightly desaturated for my taste. It doesn't exactly convey silence to me (that's not what comes to mind, if I didn't know it was this challenge my first thoughts would hav been strength, or age, or steadfastness, etc.). On my monitor the background shadows are really dark.
I like the way the details are hard to see - it adds to the mysterious silent effect. The blue sky poking through at the back seems to reduce the effect a bit, though.
