Good luck! Post some examples.

I am finishing a strong cuppa cawfee right now (Sumatran). I had a fine hike yesterday (Point Reyes National Seashore, Callyfohnia), tuckered out, and a long snooze.

Today is gearing up for rain so more indoor-yesterday sunny mid sixties. Verra nice!

Quote - need a triple espresso shot latte before i can sit at the rig today.

i'm feeling the challenge today. 
time to put all the shader lessons (special thanks to BB!)  to the test --> vrooom vrooom

feeling somewhat intimidated.  adding an xtra half shot for courage.

it might help if i understood the difference between bias and unbias, i think it has something to do with light.
