not sure how much help i can be... my last cam was a 4mg & use the tiff to work on, like you, in PSP8.1...

are you resizing it first before applying the effect? which can change the look... hmmm... well darn i'm at at loss... maybe you could post an example of the artifacts? could be compression or oversharpening... but no, not if they appear as soon as you apply the effects... (thinking outloud)... sorry, still don't know right off... i'll tell you my workflow: 3 things that help me with my Olympus images... under PSP's enhance photo: clarify 1-2 edge perserving smooth 1-2 & sharpen then i go from there with whatever i want to do... this works for me
