Scanning
Those Images
If you are going to post a relic, if you can not clean it good enough,
try adding another piece of glass between it and the scanner glass.
.
To post a ring, one way is to take a piece of foam and cut a slit
in it.. place the ring in the slit and lay it ring first down on
the glass.
To minimize the shadow affect, lay a thick wood picture frame on
the glass and place your coin inside it. This will keep the cover
up off the coin and disperse the shadow. In place of the wooden
picture frame, you can try household things like plastic or glass
bowls etc. You get the idea.
.
To scan those darker coins like Indian head pennies and large cents:
after you have scanned the coin, use your image program to experiment
by adding red color to the pic and then half as much green color
until you get a beautiful copper/tan color. With nickels play with
the brightness and contrast to improve the 'V' nickels and Buffalo's.
Remember many coins don't scan into sharp focus so you must improve
the focus with your image program.

Most of you are probably familiar with scanning techniques but
every now and then comments are posted and I thought it might be
helpful is there was a basic guide for reference. There are many
other ways to save and post images but this is intended for those
who maybe have just bought a scanner and would like to show off
some of their finds. This is a simple and effective way and can
save space on your hard drive.
When scanning any image there are a number of points to take into
consideration. Firstly what is the scanned image going to be used
for? Is it purely for the sake of posting in the gallery, for your
own records or perhaps for ease of identification or perhaps all
three. If you want am image that will enable you to zoom in close
enabling you to identify things such as mint marks on a coin etc,
then high resolution, 600dpi or greater can be used and saved in
various formats such as tiff, jpg or the hosting software programmes
own file extension (recommended). If the image is for your own records
or just for the gallery then 300dpi might be a better option. The
preferred format for images to be shown in the gallery would be
jpg, this allows excellent compression with little loss to overall
quality. Most software programs will offer you a choice of formats
to save as, and this is where choosing the image's purpose becomes
paramount. Most scanners will supply their own software for scanning,
and this can be used as a way of scanning and saving files, however
if you have other software programmes on your pc such as Corel Draw,
Paint Shop Pro, Photoshop, Livepix etc, it may be preferable for
you to scan from within these packages. This will allow you more
manipulation of your image, cropping, skewing etc before you finally
save the finished scan as a file. It is a good idea to, when you
first scan and save the image, to save it with no compression in
the file format of the software package you are using. When this
has been done you can open the file once again, manipulate it, edit
it, in fact do what you like to it before saving it as a jpg file
ready for posting in the gallery. Doing this will enable you to
scrap any alterations you have made knowing the original file is
always there to be opened once again and at its highest quality.
Once you are reasonably happy with the image you want to post, save
the file as a jpg, this should be available on the drop down menu
within the programme you are using. Usually you are then asked for
the amount of compression you require, on more basic packages this
will be low, medium or high, but on the more advanced it will be
shown as a percentage. Choosing the level of compression is really
dictated by the final size of the file needed. For the gallery,
file sizes of approximately 50k are ideal and provided you have
not scanned the image at too high a resolution in the first place
saving the file at one of these levels then checking to see its
size should be straightforward. I've found that compressing a file
to approximately 50k is more than enough, little quality is lost
and storage space is minimal (we only have so much space on the
gallery for images). When posting into the gallery another option
is offered and this is the resize option. Most pc screens will be
running at 800 x 600 so this is a good size to pick. Even if your
screen is optimised to show more colours and a greater number of
pixels, the image will still look excellent, will download faster
and will enable other users to view it at their optimum resolution.
