and keep the "best friends" busy.. Hi! 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) It counts! 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. ;-) kind regards ric above images: first 768 x 512 32k 2nd 1024 x 768 58 k Is the a big visual-able diference (without zooming!) ? Sorry for the *huge* images ![]() original image from 10d , 2'400 kbytes |
