Scanning Miniatures
09/22/00 by Kenneth Taba

Theory:
(the basic idea behind scanning miniatures)

     The object of scanning miniatures is to show them off on the web! At least for this articles purposes. You want your images to show the details clearly, at least I do. So in general terms this is what needs to be done:

  1. Scan the miniature directly on the scanner bed at a very high dpi (300) and at 200% of the original scan size. This gives an initial file size around 9-14mb as a bitmap. This is my starting point.
  2. After this I crop the image and save it as a jpeg.
  3. Then I manipulate the image to correct the color and sharpness so that it looks as good as the original but not better. I save this image too.
  4. Then I resize the jpeg to around 800x600pixels for general picture size for use on the web. I also may sharpen the image again if it needs it.
  5. Then I resize the jpeg to around 100pixels and sharpen it to use as a thumbnail for my web page.

My method:
(what I actually do)

     First off, I scan my miniatures directly on the scanner bed. I use a HP Scanjet 4100C (I think, it belongs to my father). My default settings are 150 dpi resolution and I change that to 300 dpi. The Higher the setting the clearer the picture (also the file gets really large). I also set the size of the scan to 200% of original image. I end up with an initial scan of 9-14mb. Then I crop the image so that the picture is only a little larger than the miniature, this reduces the file size to 1-4mb.
     The reason for all of this so far is that with a "large" and "detailed" image to start with. Any adjustments like converting it to a jpeg (compressed image) and resizing the image to 800x600 pixel sized image will keep the image really clear and sharp because you already started with a lot of detail. Also, the details are as clear and visible as reasonably possible.
     After the image is scanned, I save it as a bit map (1-4mb) this is my original so that if I really screw something up I have a copy of the original scan to go back to.
     Next I convert/"save as" the bit map to a jpeg. This is done in MS Paint right after I saved it as a bitmap. Then I use the MS Image Composer that comes with MS Front Page. Any good imaging program is supposed to be able to do most of the image adjustments you'll want to do to make the jpeg look as much like the actual miniature paint job as possible.
     Using MS Image Composer, I adjust the picture for sharpness and adjust the colors to look as much like the actual paint job as possible, then I save that as my "very large" picture. Next I resize it to around 800x600 pixels and re-sharpen if necessary and save it as my "normal" size picture, this is the size of the average "large" picture on the internet. Then I resize again to around 100x100 pixels to make my thumbnail pics.
     That pretty much sums up what I do with what I have. My goal is provide as clear and detailed an image of my work as possible. I don't want the picture to look better (which would be misleading) so I try to get as close to the real thing as possible. Also I use such large images because you can see the detail as if seen through a magnifying glass.

Oh yeah, in my picture galleries, my thumbnails are listed with 2 options to view. The smaller ones are the average pixel size variety. The larger file size are my really large images that show all the details very clearly (or as clearly as I could make them).

And thanks to Tim for the following tip:

You are probably better off doing all of the adjustments to color and sharpness before converting to jpeg, since the are more pixels to work with before jpegging to 72 dpi. After jpegging ony a little bit of shapening wil be needed.
