Ted, no offense to your photography, the content is delightful. But the pictures *are* noisy, and I'm interested in why. I've seen many M8 pictures at 320 that were not very noisy, yet these are. Possibilities include:
- Underexposure (particularly in the last picture, where there are splashes of sunlight tha may have skewed the exposure). The boys' hair is very noisy, and the clothing is as noisy as some ISO 1250 pictures I've seen.
- Different RAW converters, or an NR setting in the converter.
- Without the IR filter, the camera reads too much IR light, and underexposes. With the filter, things are back in the visible spectrum only, and things are more as they should be.
- Sample variation in the sensor or electronics.
- Proximity to a source of RF interference.
- Demons, gremlins or poltergeists.
For what it's worth, I recently spent a day with a friend shooting his M8 (V. 1.09, recently back from Solms). We shot at various ISOs with an IR filter. We didn't get noise like this until 1250/2500. We shot one sequence of portraits in very dim light with the M8 and a Nikon D200. The M8 shot was unbelievably good. The D200 had the knd of noise the shot with the kids has (worse, though)--there was uniform noise everywhere, and the hair blocked up into black with very ugly color blobbing at the interfaces between pure black and a little detail. He was not using Capture One--I think he used ACR, but not absolutely sure.
Sorry, I don't have the pictures, so I can't post them.
