Last week review 16-2017

Last week review 16-2017 and this week we were suprised with very fresh and almost temperatures;-)

Last week review 16-2017In the article for this week we checked out a little bit on Guetzli, a new JPEG encoder shortly published as open source by Google research. The new encoder should save 35% of storage space according to Goolge and produce compression artefacts which are more liked by the audience tested in the research project.

Background of such a technology is of course saving storage space for websites and save data volume for mobile network connections. Since this new encoder is available as a Windows binary i gave it a try. With a very detailed image from my Lumix i’ll got a reduction in image size of 19% only. But this reduction on image size was a result of a 11 min. encoding, which is not acceptable in a production environment. But we have to kepp in mind that Google published a research result, so optimizing potential should be very great.

Last week review 16-2017A short time ago i bought a Panasonic 7-14mm/4.0 to substitute my Olympus 9-18mm lens, because once in a while i need more wide-angle on my Lumix. The Panasonic 7-14mm is a beautiful lens even though you must live with limitations having no opportunity to use filters and i like to use strong ND filters like the Haida 3.0 or graduated filters with the lens.  Now Panasonic is going to release a 8-18mm/2.8-4 with a mount for regular screw-in filters with 67mm diameter. This lens would cover the same focal range like my preferred 16-35/4.0 IS lens from Canon, which i love on my Canon 5D MK II.  But with a price of arround 1.300 € the lens should have a superior optical performance to think about this new lens. For my 7-14mm there are solutions to use filters, even though not cheap 😉

Last week review 16-2017Also this week WordPress 4.7.4 was released. This version was installed on all my blogs automatically which is very convinient. Version 4.7.4 is a maintenace release correcting some bugs and errors of prior versions. Dann kam diese Woche WordPress 4.7.4.

But anyway this was an interesting week and I hope you like the blog posts and i’m looking forward to your questions and comments.
