and keep the "best friends" busy..
Sunday morning. The zoo of Bale (Switzerland.Basel) is opening at 8:00.
weather good, accus charged, Weather a beauty.let's go.
Some hours later, back at home, afther transfering all pictures from the mobile storage device,
usualy 2 steps are required.
- Backup to an other pc over net, 1:1 copy to CD or DVD.
- Image optimization and reducing image file size
The image size, depending of the subject, can be reduced between 30% and 70%, more or less
(A bird in the sky uses mutch less "informations" as a duck on a complex backgroud with trees and water)
I never count the amount of pictures I take.
Walking around the zoo only 4 things belongs: the animal(s), the respect of the animal, the canon 10d and myself.
Most of the time listening to music, waiting for a good shot, the ipac 3850 spends about 8 H mp3.
Came back with 859 Pictures, total file size 2.2 Gigabytes. =1/2 DVD)
Due I want to leave as most as possible of the pictures on the Harddisk(s),
with a shareware tool (working over2 year now) in the batch mode, I let reduce the PCs the image size
and a litte bit of optimisations. Per Image, about 3-5 secconds are used. (get over shared network drive,
processing, rewrite over share networks drive)
Putting just one PC, even a fast one, takes hours with this amount
I didn't stop boinc, just started the optimizer and put, this was new, 8 PCs to "crunch the pictures"
Not counted the time exactely, but afther having a late lunch, the work was done.
afther reducing/opt. Pictures, total file size 1.05 Gigabytes. =1/4 DVD)
Sometimes I'm running, with an other Tools, also in batch mode, additional resizing tasks. this also can be done
"distributed", but this take more works to do, so also a couple of CPUs can be putted on
For publishing here, I "more" reduced filesize by cutting down the amount of pixel and reducing colors.
Sorry, I'm not sorry for my bad english, I can't do it better, so can't be sorry. ;-)
