The purpose of SPP
Oct 14, 2012

This is how i see, value and use SPP - it works for me and i am happy with it.  Even sorting out and post processing several hundred of wedding pictures is no problem.

All CMOS sensors create noise and/or are sensitive to noise - this is a Canon 5DmII picture without noise reduction:

So the noise reduction HAS to be done at some point (and removal of other sensor/converter related artifacts) - Canon choose to do it in the camera, since the DIGIT processor probably is more powerful compared to the TRUE processor in Sigma cameras.  Therefore i think (believe) that Sigma is doing the picture 'restoration' with SPP.

I have managed to catch a screenshot just when the picture is loaded (or the embedded jpg?) and before the 'restoreration' has been done:

After the restoration i press 'Auto' and the picture looks like this:

Sometimes i use the 'X3 fill light' a little but thats more the exception than the rule.  Then i export the picture as 16bit .tiff and do the 'makeup' in LightRoom.  I don't always use 'Auto' - actually i only use it if the picture is a little underexposed, it feels like SPP is better to find the optimal balance compared to me skills.

Only error in SPP 5.3.2 i have noticed is the (sometime) missing EXIF info in .tiff files.

Maybe i am wrong, but i am sure i will be corrected then - so if someone has a better explanation i am looking forward to hear about it.
