i am trying to scan some very old family pics to send abroad.these pics arein black and white ad after scanning them the results are too black and white if you know what i mean ie there seems to be very little contrast and it appears that i have no control either in settings before scanning or trying to correct with irfanview after. xp pro sp2 and xerox x 2400 scanner, any ideas please?
Isn't it just a case of scanning in Greyscale or even in Colour rather that Black and White, which gives you only two possibilities either Black or White? If I have misunderstood your question I apologise!
I am not quite clear what effect you are getting; perhaps you could post an example on something like image shack, or similar.
I do a fair bit of restoration of old B/W pictures for the family; some in very bad condition. I have quite an ordinary run of the mill Canon N1220U scanner, select greyscale, and scan at about 350 dpi; (this will be reduced in the photo programme I use; Paint shop pro).
To illustrate the sort of results I get, have a look here:
The first picture of my Grandmother was taken about 1910, and the hole to the top left was caused by a bullet in the 1st World war, when my Grandfather was shot - (fortunately he survived).
Original scan to the left, restored on the right.
The second picture of him with a field ambulance, (1914 vintage), was in good condition, so I decided to colourise it for the family. A lot of work, but I think the results justified it. Again, original scan is on the left.
