Automatic photo tagging

Wednesday, January 7th, 2009

MyHeritage, a genealogy web site, claims it can automatically tag photos of people.  It uses face recognition to find faces in uploaded photos, then gets you to identify them.  The idea is that you only identify each person once, and it can automatically tag other photos of that person for you.

Stitching panoramics

Saturday, November 15th, 2008

Earlier this year I took five side-by-side pictures of Bournemouth Pier and stitched them together using hugin.  It’s quite easy: you just click somewhere recognisable on one photo, click on the same feature in another, and repeat several times.  I took the entire set of pictures with exposure lock set, although it doesn’t seem to have worked very well for a couple of them.

Clive Wright’s 35mm slide rig

Friday, November 14th, 2008

There has been quite a response to a comment made by Clive Wright on a previous post about digitizing 35mm slides.  Here’s what Clive said:

Having recently purchased a new camera, a Fuji Finepix S8000fd with 8Mpixels & a SuperMacro facility focusing down to 1cm (0.4″). I placed a slide on a small lightbox and held the camera approximately this distance in front of the lens and produced a fair digitized copy. Even the facial detection system works in this copy mode!
To eliminated camera shake and make the copying easier I then designed and manufactured a simple rig to attach the camera to and position the slide to be copied at the correct distance cover the entire film area, negating any need to crop the digitized image as the camera has a 3:2 quality setting. I have used this rig with both a lightbox and with a white diffuser positioned behind the slide using either the sun or a 60watt lamp as the light source.
The beauty of this rig is that it doesn’t require a steady hand (older people again) or the use of a tripod.
