All my slide's are to grainy.
I use agfa snapscanE52 scanner , Fuji SensiaII , photoshop 4.0
This is one of the rejected slide's
Can't anybody give my tips for a better scan ?

you don't say what speed Sensia you're using. It does appear from looking at the pic that it was taken on high speed (ISO 400+) film.
However, there is something else that can cause a similar effect: if the original is too dark and has to be brightened or have gamma increased significantly. I'm wondering if maybe that has happened here - looking at dark areas like the engine intake - you can see how the color transition (from dark to light) has become pixellated. So it could be to do with brightness gamma adjustments that have had to be made to get the overall tone of the picture correct.
I would be interested to know how other slides you have scanned compare to this one.

I would concur with S4 - looks like a fairly aggressive attack has been made on the tone curve, resulting in "gaps" in tonal range. Also, 5 minutes removing some dirt specs from the sky with a clone tool wouldn't go amiss.
All that aside, I am impressed by the quality of what is, effectively a flatbed scan of a slide - given that the optical resolution is significantly lower than dedicated film scanners and, I assume, the resolution acheived in this image is through scanner interpolation - the result is remarkably good. But perhaps it is the interpolation process which is causing the "grainy" result?
