Simple Scanning for Detectorists
« on: September 09, 2014, 09:09 »

This is one of my most popular posts - resurrected and updated. How many times have you seen a blurred coin picture on your forum taken on the hand and with a lot of superfluous background? I’m sure that if you submitted the picture to Gypsy Petulengro she would be able to give you an accurate palm reading (the hand is always in perfect focus).

Very good advice John, there would be a lot of us with scanners who were unaware of this process and the quality results it can produce. If your out in the field and not able to acess a scanner almost all of the 'Smart Phones' have a function in their camera menu called HDR (High Dynamic Range), the phone camera will take 3 photo's at different exposures then combine them into one image which helps stop the dreaded blurred coin effect, I take my hat off to Forum members who seem to be able to identify these blurred images with amazing accuracy....cheers Colin.

Thanks John...

Ringa used to only use a scanner on her jewellery...till her old computer blew up, and the new one wouldn't accept the older scanner...She has since been using a camera...taking 649 (slight exageration ) photos of each object before being happy with the result...After reading your article, and doing a bit of research, she will soon have a new scanner  for her upcoming birthday :D
Thanks again for your article

This is for ohb1 really. Be aware that I don't think that the scanner is the best tool for taking pictures of rings. A camera would be my choice every time. The ring is an awkward shape for a scanner. I had a quick try on both. The results speak for themselves.

Thanks John..
Ringa is my detecting partners forum name,...she has her fair share of ring finds that will remain with a camera photo, but she also dabbles with threepenny earings and bracelets, and makes up silver necklaces from odd earrings  that have been found..I think the scanner will come in handy for the flatter objects ...if not, it at least got me out of wondering what to buy her for her birthday ;D

Sometime a web cam is easier to use as one can see the picture on a monitor before the snap.
This one unmodified except for cropping to size, natural light and somewhat balanced depth of field to see both front and back of ring.
