Excessive noise on the Mark IV
Harvey Levine, Photographer

| ->> I have 2 Mark IV's and have always been impressed the lack of noise at high ISO's. However, recently, I have been getting high levels of noise on both cameras independent of what lens I am using. To the best of my knowledge, I haven't changed any settings. Any thoughts on what could be going on? Any setting I should check? |

| ->> If you're shooting jpegs check Custom Function II -->#2 and see what you have it set to. By default it's set to 0 which is standard noise reduction. You could have changed it to 3 and disabled it by mistake. That would make the most noticeable difference at higher ISOs. |

| ->> Perhaps you changed something in the software you use to process the images, and not in the 1d4. Especially since it has happened on both of your cameras and it might be unlikely that you made the same changes on both and don't recall changing anything. Do you use Lightroom? Perhaps a change there to your presets? |

| ->> Harvey, did you kick up Highlight-preservation or Highlight priority settings recently? This can really crank up shadow noise... |

| ->> Thanks for all your suggestions. I am using the Peter Read Miller settings, using picture style Standard. I am seeing the increased noise when I look at my images in Photo Mechanic. |

| ->> Check your settings in PM go to Preference > Contact Sheet and see if generate high quality thumbnails and sharpen thumbnails are checked, if not check them and see if it makes a difference. |

| ->> I have high quality thumbnails checked. I think checking sharpening woud increase the noise. The noise carries over when I open the image in CS5. I was comparing my images to a friend who shot the same event with his Mark IV's, same lenses. I shot at 500 2.8 ISO 4000. Only difference was he shot at 5000 but had less noise. One could argue that I was underexposed but 1/3 stip shouldn't make that much difference. |

->> Harvey - by chance are these all indoor shoots taken at the same location under the same lighting as previous months/years? If so, what kind of lights are in the gym / arena? Mercury vapor by chance???
I have one gym (with MV lights) I shoot in that seems to get dimer each year and month I shoot in it. Hope you understand where I'm going with this. Maybe it's not the camera ... maybe it's the lighting beginnig to loose its punch. |

->> Before you go any further, realize that you might be trying to compare apples to oranges (ISO 4000 to ISO 5000). It was documented a few years back that some (maybe all?) camera's perform best at well, for lack of a better term at their native ISO and every ISO in +/-1 stop offers the best performance. So if the "native" ISO for a camera is 160, then 160 is going to look better than 125 and also better than 200. Going up from 160 in full-stop increments is 320, 640, 1250, 2500, 5000. If the 1DIV is like this then 5000 would in theory look better than 4000.
Someone who is geekier than I should weigh in on this. |

| ->> garrett is on to something here. I wondered why my iso2500 files look slightly better with less noise than the iso2000 ones....this would explain it. thanks |

->> There was a pretty lengthy thread about native ISOs and frankly, I'm not sure I think it makes a difference and even less sure it makes a noticeable difference. Anyway, here is the thread:
