Canon 7D Red Detail
Just been looking at 7D sample images on Imaging Resource. Can anyone
explain the lack of detail in the red fabric on the 7D compared to the 40D (The red fabric in the top left of the photos, in the 3 o' clock position): 40D, ISO 3200: http://75.126.132.154/PRODS/E40D/FUL...0DhSLI3200.JPG 7D, ISO 3200: http://75.126.132.154/PRODS/E7D/FULL...200_NR_STD.JPG |

The version without noise reduction is much better. -- Regards, Robert http://www.arumes.com |

The version without noise reduction is much better. And yet it appears only to affect the red channel. The proportional scale on the right and the other colors seem unaffected. In fact, the scale shows more detail from the 7D. -- Ray Fischer |

In fact, the scale shows more detail from the 7D. You'd need the raw file to see whether it's a glitch in in-camera NR, and/or saturated red channel on the sensor (but something's wrong - it looks really bad). If the raw is okay, then nobody expects ISO 3200 to look great with ex-camera jpegs from an APS-c camera at 100% pixel view - do they? |

So you don't need the RAW to see where the lack of detail (which is clearly visible without zooming at all) comes from. -- Regards, Robert http://www.arumes.com |
