<p>[QUOTE=&quot;desertgem, post: 4886143, member: 15199&quot;]The problem with the ads is quite misleading. It is like saying a Corolla has a 400 hp engine because it supplies 1oo hp to 4 wheels and 4 x100= 400!&nbsp;&nbsp; If you have a USB ( non-medical ) camera that advertise 100X , take a photo of the field of a silver dollar, and it should look like this below. ( Morgan on left, Peace on right) with a lab ( non usb) microscope. ( I teach microbiology off and on at college). This show magnification ( size) and resolution ( separation ) and no software ( faked fill-in of pixels).</p><p><br /></p><p>[ATTACH=full]1178994[/ATTACH]</p><p><br /></p><p>The photo below is of the Morgan $&nbsp; at 400X....you can see the ridges individually, This was done for an old thread on why morgans tones more often and stronger than peace $, but here just to show resolution. Most USB @ 400 power would show a pixelated flat field.&nbsp; The USB manufacturers use the normal projected ( on the tv screen) to calculate magnification. They are almost useless for small varieties IMO, Jim</p><p>[ATTACH=full]1179006[/ATTACH][/QUOTE]</p><p><br /></p>
