Canon Digital Rebel XT 8MP Digital SLR Camera |
I'm also borrowing two Canon lenses, the EFS 18-55mm and EF 75-300mm. I still don't really know what f/stop means so I didn't list that in my description haha.
It's been overcast all day, but it looks like things are clearing up in time to see the waxing gibbous moon rising in the east.
F-stop is basically how much light you are letting in (low number, lots of light, high number less light). I am not sure if it's the same on a DSLR, but in the manual film days, you turned a ring on the lens to change the aperture. Each stop/number on that ring was an F-stop. It works kind of like your eye's iris. Open in low light, closed in heavy light.
