More on photography

Hi all, First off, thanks for the advise to stay away from
NASE…I appreciate it. Next question: I have caught a few of the
posts on photography and would like to shoot some of my peices. I
have a Canon AE1 camera and a flatbed scanner. What type of
len(s) would I need to get for this camera to shoot close up
shots? Also, at what resolution should I set my scanner at when
posting photos on a web page? Is it better to use a dark
background when photographing gold items? I am a rookie at this
stuff and any help would be appreciated. Thanks, Ken Sanders
