"Flickr.com looks great! Let's upload the photos from the trip to Argentina“
How it beganHow it began
"Wow! Your Argentine picson flickr.com are gorgeous!But do you have this one
in better resolution?
"How do I find thehires version?"
How it began
dilemma #1: one photo, many versions
● share: 1024x768 px JPEG on flickr.com
● edit: hi-res PSD/TIFF on your harddisk
● backup: the same on a DVD
● distribute: modified TIFF for your client on
your FTP
but why this mess?how do we keep track of all versions?

dilemma #1: one photo, many versions
● there is no „all purpose photo store“
● reach vs. transfer rate vs. capacity
● your photo collection is distributed across multiple
stores, but there is no tool to manage it
– Adobe Lightroom/Apple Aperture/... Adobe Lightroom/Apple Aperture/... »» limited to local HDD limited to local HDD
– flickr/picasa.com flickr/picasa.com »» limited to photos on flickr/picasa.com limited to photos on flickr/picasa.com
– photo collections on DVD? Removeable HDDs?photo collections on DVD? Removeable HDDs?
solution #1: picurl photo versions
● picurl scans all your photo stores and efficiently
extracts the „visual essence“ (thumbnail +
metadata)
● picurl will automatically recognize multiple versions
of your image and merge them to one dataset
(coming soon)
● picurl provides an overview of all your photo stores.
How it works
metadata extraction
„I edited all captionsof my flickr.com photos. Now you can use them for your photo dvd.“
the next problem arises...

„grrr.... I had to download each of the 99 files manually and the captions were also missing!!!“
dilemma #2: missing metadata
aperture, flash,cameramodel,...
creation timelocation (GPS) copyright hints
captionskeywordsthumbnail
photosharing services don't offer metadata export forendusers (only programmatic)
• show me all night shots
• show me all portraits without flash
• show me all photos taken last summer
• show me all photos taken at Vienna
• show me all photos taken by my OLYMPUS e410 with at least 3 megapixelresolution
metadata search possibilities
solution#2: metadata backporting
picurl converts proprietary metadatato standardised EXIF/IPTC entries
Hi John,
we could use one of the following pics for the cover of the company magazine:
http://www.pixelio.de/details.php?image_id=272698&mode=searchhttp://www.istockphoto.com/file_closeup/foodanddrink/eating/6199964http://www.outtakes.com/work/graphics/work.icecream.400.jpg
a meaningful e-mail
"the cover is perfect... but from where did we download this photo again?"
some days later...
solution#3: visual bookmarks
picurl started 10/2007
written in Python, shell tool, later w GUI
OOP/Plugin-Architecture
0.0.3 released the next days
challenges: technical project setup, quality of metadata
libraries, coding conventions
