With regard to noise, I have not seen the results from the 54m but essentially it should be very similar to the 54s which does display noise in the shadows at exposures of 1sec. Temperature will definitely play a part and working for prolonged times in hot conditions will increase the noise. I have been told that Captureshop 5 (which I assume you are using as the 54m isn't supported in earlier versions) has software issues in relation to noise on the 54m. I have shot 54 single shots on both 4.1 and 5 and not noticed a particular difference but this has not been thorough by any means.. Go back to the supplier and ask for more info. With regard to the colour calibration, the sinar supplied "calibrations" are generic and will not offer the best possible results. To use them you will need to grey balance using the colorpicker on a grey object in a captured preview, when happy with the result hold the alt key to preserve the grey balance for future captures. Reneutralisation via this process through the day should maintain a consistent grey. A more accurate solution is to take an image of the macbeth colour chart 24 patch or DC (sinar seem to have omitted support for the preferred SG chart). The procedure for doing this is under- capture> calibrate colors. Don't overexpose the chart and try to ensure that it's evenly lit. This calibration can then be saved and utilised via the same process as using the generic calibrations... Although you will still have to neutralise to find the correct grey point when shooting with a changed colour temperature. It might be worthwhile to create a set of calibrations to be utilised at different times of the day/weather conditions..... Rolls Royce approach will involve bespoke camera profiling, done in addition to calibration this will involve the creation of an input icc profile... Whether and how well this works I don't know.. It certainly is on my list of things to test and will be looked at properly now CS5 is out for real (this function is only supported in the latest release). Others on this list will have direct info on this, which I'm sure will give some help as to whether it's appropriate, it is expensive... To set this up is going to be a least �2500 if you're starting from scratch.. Good luck, let us know how you get on,
