In Valid Logic

Endlessly expanding technology


Was out in the backyard snapping a few photos with my marco lens yesterday and kind of liked this shot (note, it is an artistic rendering).  I got this nice Canon 100mm f/2.8 Macro lens for Christmas, but haven't had much of a chance to use it yet.  Kind of interesting though.  At 100mm with something right in front of the lens, depth of focus can be wafer thin.  A mid-range aperature of 4.5 (mid-range in my opinion) is still wafer thin.  For something very up close, you almost need to do f/8 just to get the whole object itself.  Also, for macro, you need to be very concious of your breathing and stability.  When you're up that close, with the thin DOF, the slightest movement can cause your focal point to change entirely.  I found I kept focusing and then I'd sway back just a hair and would be out of focus.

Having a backyard now will be nice.  Should be a lot to take photos of, provided my allergies don't kill me first.  After spending some time on the weekend weeding and cutting out some dead growth, things are really coming back quickly.  With spring upon us, it is interesting how a little bit of TLC in the yard and a few days later, it can really look outstanding.
