360dpi

72dpi
scanning with 150 dpi

1) My scanner does not have a descreen function. However descreen is often used to remove or rather improve the effect of a moire pattern on scanned images. This is a better method than applying a blur or despeckle filter, resampling then using a sharpening filter.

2) 360 dpi is the best for print as it retains the greatest amount of detail.

72 dpi is the best for web as it is sufficiently detailed for monitor resolutions and web sized images.

150 dpi I believe is the best resolution for presentations as it has enough dpi to be expanded and retain resolution over a basic projector area.

3) I did with 150 dpi resolution. i picked up gathered skirt and pink colour fabric
