Sigma Software

... is often done from completely different viewpoints:

If you compare it to typical vendor supplied software the conclusions are often:

• its OK or better than some other vendor supplied software
• it provides the best processing for Foveon files
• it fairly stable

However if you compare it to professional tools like Photoshop, Lightroom, or Capture One the conclusions are often:My take on Sigma Photo, starting with the good points:
Note, that the judgement of stability, is very different dependent on where you come from: in professional software it is assumed that no problems occur just because you enter a directory with thousands of raw photos, or a used to quickly responding software. Thus an instability in handling such situations (which seems to be a common complaint with SPP) leads to gripes with the software.

• it very slow
• it doesn't provide good colour adjustment and correction
• chromatic aberration correction (useful for DP1M) is inadequately implemented
• it is very limited in functionality
• it is fairly unstable

Based on these observations, I sincerely hope that Michael Reichmann's public letter to sigma, will not fall on deaf ears, and we will eventually get support for DNG export (which can be done using the linear DNG option, without Sigma giving away all its algorithms) in Sigma Photo Pro or support for the DPxMs in one of the professional tools. For me, I will leave SPP behind as soon as either of this things happen... and it cannot happen fast enough

Phew... this turned out longer than intended, but maybe, just maybe, it cleared up some of the differences in perception of SPP.
