Photo Tools
1) Sony Mavica CD350 3.3MP digicam with 3x Optical Zoom and Macro features. This is probably least important ingrediant. Any camera of tolerable Point-Shoot-on-up quality can work ok .
2) to Avoid "bowing" of image (fat at the middle) pull the camera back and use optical zoom, rather than getting really close and using plain macro.
3) Get a Copy stand. Camera points straight downward. I got one on eBay for $15
4) lightbox to backlight knives - not a necessity but a nice touch especially if they are going on eBay
5) Foam Core (posterboard) plus black and white paper for "mask" cut thin track into the foam about the size of the knife - but more narrow. Put this on the lightbox. Thus, light shines through and around the knife area. Cover whole thing with white paper (or leave cut-out open. No prob either way). Put knife so it runs along the cut-out in the foam. Put black paper to a couple mm. from edge of the knife on either size, and use "triangle" cut out black paper to get near the ends of the knife. This gives a dark cast to the edges of the knife, avoiding the white glare that seems to plague many pics at edge of the blade. Also makes it much easier to later digitally delete the white backdrop to isolate the knife. If the knife is left hazy at the edges, the "magic color wand" on photoshop tends to delete the bright parts of the knife. With dark edges, it does better at avoiding this problem.
6) lighting- couple 500 what photoblue bulbs. Hot Hot bulbs. Depending on mood- either direct lighting (rare), indirect lighting (tilt the lites away from the knife(s) and bounce light off ceiling or walls or white foam board.), or diffused light (put a white lampshade around the knife) - each has real plus and minus. Use trial and error.
7) once picture is on computer in Photoshop- fairly easy to select the white outline around knife to make cut out and deletion, leaving pure knife on empty backdrop. Use a bit of "feathering" (maybe 0.8 pixels) to take the rough edges out of the knife cutout. Then you can put whatever (if any) backdrop around the knife from other digital images. Despite all of the above nastiness, at this point i can usually shoot a knife, engraving, tang stamps / imprints and handle for a given knife in about 10 minutes- suitable for webbing. Generally target the "big closed knife pic" on the left of the page for around 1000-1250 pixels tall. Hope this helps.
