Canon 400D 54mm 1/4 F11 ISO 800 <- I've always wanted to write something like this (;p)
To learn about the exposure triangle read here at digital-photography-school.com.
I'm starting to really see how a DSLR edges out on a point and shoot. This shot could not have been done with my previous Sony. The only light source is the lamp you see in the picture, this photo was just an experiment of several things:
2. choosing an aperture for maximum depth of field
3. compensating the exposure with the appropriate shutter speed
4. compensating with ISO.
I'm quite impressed that at such a high ISO of 800 the picture is acceptably not grainy.
1. In retrospect I should have illuminated the flowers from the front.
2. This is actually a significant step for me, as I am stepping more and more outside of the automatic functions to more manual controls...
3... and the epiphany about understanding the exposure triangle came to me only this morning, while driving to work :)
