I shoot exclusively in manual mode.
Picture #1
Camera: Canon EOS 7D
Lens: Canon EF-S 17-55 f/2.8
Focal Length: 20mm
Shutter Speed: 1/60 sec
Aperture: f/9
ISO: 100
on this one I wanted the slowest shutter speed that would let me hand hold the camera and still get a crisp clear picture (to try and maximize the motion blur). 1/60 was the lowest I could go, so I adjusted the aperture accordingly.
Picture #2
Camera: Canon EOS 7D
Lens: Sigma 10-20
Focal Length: 10mm
Shutter Speed: 1/800 sec
Aperture: f/4.5
ISO: 100
that is the info from one of the pictures, it is actually a 3 Exposure HDR image. It is almost impossible to use natural lighting and get a good exposure on my black rims as well as the rest of the car without using multiple exposures. I pretty much always shoot 3 bracket photos. Sometimes I will use HDR, sometimes I just use one of the three shots but then I have a few different lighting variations to pick from!
Picture #3
Camera: Canon EOS 7D
Lens: Canon EF-S 17-55 f/2.8
Focal Length: 21mm
Shutter Speed: 1/640 sec
Aperture: f/2.8
ISO: 100
HDR again like pic #2.
