    "OK people, whats the most effective dpi to use whilst scanning?"

    I currently scan at 200 dpi because my scanner seems to work fastest at that resolution.

    I compress the files though and that speeds upload here on Delcampe, but I really compress for that big site where I use a third party image storage adn listing site and my images were hogging space I had to pay for.

    Haven't noticed any loss in viewing quality of images. On that big site, I have super size images so buyers can see any faults etc for themselves.

    I compress files by using settings in the scanner software, look for something like "jpeg image quality ".

    My compressed file size now ranges in the 50-70 kb range and upload to sites fast. Haven't had any complaints about image quality and they seem fine to me (but what would I know!).

    Nigel,
    I am happy (and very conservatively set in my way) working the way I do now. The time saving, if any, would be very marginal.

    As far as stamps is concerned, I tend to put a piece of black paper on top of them. As the margins on stamps are normally white, this contrasts the perforations very well. Of course this rules out auto-cropping, as the scanner sees the black paper as a single object.

    For stamps I use a standard black stock card with the clear strips cut down to about 2mm (i.e. just enough to hold the stamps level without blurring)

    For larger sets or stamps I scan two or three times with one row of stamps then use Photoshop to layer them together into one image before cropping and resizing - dead easy with a bit of practice
