A Macro

I rented a Tamron 90mm f/2.8 SP Di VC USD Macro. Sunday, I am doing an Vernal Pool Walk in the Sourland Ecosystem Preserve near Mountain Road in Hopewell. I am hoping I will get some cool photos of frogs and newts and maybe even tadpoles. I have never used a macro lens before. Between today and Sunday, I have some time to read through the manual for the lens and practice in the backyard.
