scanning coins
If you scan your coins for showing on the web I would like to know;
What dpi do you use? What depth of color do you use? What resolution do you use? Hmmm, What tips would you have for me to make my pictures the best I can for your viewing enjoyment? Winde 'making a webpage' |

Hmmm, What tips would you have for me to make my pictures the best I can for your viewing enjoyment? Winde 'making a webpage' Hi Winde. Depth of colour: No point using greater than 24-bit for jpg, 8-bit for gif. dpi / resolution: these terms are more useful if you're thinking of printing to paper (IMNSHO, greater than 200 dpi is a waste for *that*). For webpages, its more useful to think in terms of "How wide will my pix be" and "What file size will they be?" Opinions and standards vary widely, but you don't want an image to be so large (in terms of # of pixels wide or high) that the user has to scroll to view it. 500 pix wide is good for "average" pix. I don't go wider than 900 unless I have to. 100 is good for thumbnails. Filesize: 30k=good 70k=OK 150k=getting uncomfortable 150k=unfriendly for dialup. gif= good for diagrams, graphs, titles, transparent backgrounds, animations jpg= good for photos When scanning, if you get unpleasant burnt-out spots which can't be removed with exposure changes, try rotating the coin and scanning again. Good software (eg Photoshop) is a real bonus. This topic is w-a-a-a-a-y too complex to cover all points quickly *and* comprehensively. Suggest you try it and try it and try it (so on). Have fun. -- Jeff |

If you can afford it, I recommend getting a good digital camera with a macro
mode. I think digital cameras take far better pictures than flat-bed scanners. I take pictures that wind up being about 1600 pixels wide. Way too big, I know, but it leaves me with a lot of options. I can downsize the picture any way I want for an eBay listing, or especially for insurance documentation. --Jeff "Winde Walker" wrote in message ...
