A quick tune up today before shooting tin types at AC.
Checking my chemistry for working in the heat and shooting in full sun.
f6.5 at four seconds, the temperature in the box was 88º F. If I'm careful with my pours and keep everything clean I should be good to 90ºF. Today at 90º and over it was pretty close to impossible to get a good plate.
Just a quick scan, pay no attention to the dust and cat hair. Will go in scraps later.
