category Cameras • hashtags Canon, Nikon • 2 min read

Canon has 4+ metering modes:

  1. Evaluative Metering
  2. Partial Metering
  3. Spot Metering
  4. Center-weighted Average Metering

All new dSLRs have similar modes, they just call it differently

And then there’s the manual mode. So what’s the right way? That depends:

  • On the direction of the wind

category Cameras • hashtags Canon, Nikon • 1 min read

I’m not sure that I would really want to test how tough is my camera, but some other dudes, at Digital Rev, tested the Canon 7D. Think of it as the “Jackass” movie but for cameras. For me it is much funnier since nobody gets hurt. They got their Canon 7D:
