The definition is a lens that is circa the same size as the diagonal of the sensor of the camera. This gives the pictures a normal perspective with neither exaggerated perspective like on a wide angle lenses or compression of the perspective like on telephoto lenses. The perspective looks like you would see it with your eyes if you were...
A mild wide angle lens with close to 35 mm full frame equivalent focal length renders a quite natural perspective while fitting a bit more into the frame than a standard lens. Such a lens is a very good walk around lens, and I miss having one of those. I own the Panasonic 12-32 f/3.5-5.6 compact zoom which is nice,...
I loved the Panasonic GM5. This is why I sold it. My thought when I bought the GM5 was that it would be brilliant to have a camera so small that I could bring it anywhere while at the same time being a proper camera with a large enough sensor to get really good image quality. I previously owned the...
This winter, I sold my Panasonic 20 mm f/1.7 that I bought the summer of 2017. The reason I bought it was that I wanted a standard lens and had seen enthusiasm about this lens in some online reviews. It seemed like the perfect walk-around lens with its 40 mm full frame equivalent field of view, small and light pancake...
I find it hard to make good pictures with wide angle lenses. Therefore, I mainly stuck with wide angles deliberately when I was out photographing during Easter, both at home and while abroad. When I was taking pictures at dusk on a nearby beach early in the Easter week, I put on my Panasonic Lumix G 14 mm f/2.5 prime...
I recently watched a youtube video from 2016 where Gordon Laing and Doug Kaye discussed the best lenses for Micro Four Thirds available at the time. In it, Mr. Laing says he feels that on the Micro Four Thirds system, zoom lenses do not make sense and that he prefers to shoot with primes for his own personal work. I...
I have thought a lot about this question lately since I live in rurality and most of my pictures are landscapes, seascapes or townscapes. I am not sure there really is a good answer to this question, but I think the general advice people often give about using wide angle lenses for landscapes is too simplistic. Wide angle lenses fit...
I have deleted my Facebook account. Everyone should do the same. Don’t take my word for it. Read a few articles about Facebook instead and make up your own mind whether you should give them your personal data and thereby legitimise their business practices: Facebook is a law-breaking “digital gangster,” UK government report says. Facebook may face multi-billion dollar fine...
If you run Gnome or KDE Plasma as your desktop environment, there are built in tools for you to calibrate your screen. You just need to find an .icm or .icc profile file that matches your screen to calibrate it. (See below to find one that matches the X230 with the IPS screen.) I have run LXDE up to now...
There is a function called “Ex. Tele Conv.” on the Panasonic Lumix GX8 camera (and probably on most of the other Lumix cameras) that makes it possible to crop an image in camera. I saw it described as “useless” in a discussion on a Flickr group some months ago which seemed at bit harsh to me. Of course, for RAW...
Below is a table of micro four thirds prime lenses sorted by focal length. It is not complete, so let me know in the comments if anything is missing and I’ll add it. Focal length (MFT) Angle of view Full frame equivalent focal length MFT prime lenses 7.5 mm 110 degrees 15 mm L f/2 10 mm ? degrees 20...
Generally, most hardware works quite well with Linux these days, even if it shipped with another OS. (You can be guaranteed a good experience if you buy hardware with Linux pre-installed from Entroware, System76, Dell or Purism.) A lot of hardware has open source drivers available in the Linux kernel or as packages you can install. Some hardware needs proprietary...
Lately, many Mac users have been disappointed in the hardware and to a lesser degree also the software that Apple makes. It seems like Apple is focused mainly on iOS since their earnings mainly stem from it. Some of the core Mac users in creative industries that have used Macs since the 80s are now leaving or thinking about leaving...
Sometimes, your OS will scale every app so things look right, but if you have a screen that is quite small and has quite many pixels, but not extremely many, it might work better to have the OS work at 100% and just scale the few programs that need it. This is what I do on my 15 inch laptop,...
Jeg har arvet en bok som jeg tenker kan ha interesse for flere enn meg selv og som jeg derfor gjør tilgjengelig her. Det dreier seg om Folkeskolens kokebok (Lærebok i huslig økonomi I) av Dorothea Christensen og Helga Helgesen. Boken er utgitt i Kristiania av H. Aschehough & co. (W. Nygaard) og dette er sjette opplag av 1916. Jeg...
Ubuntu 14.04 “Trusty Tahr” runs quite well on my MacBook 2,1 from late 2006. Now that security support from Apple is (silently) ended for Mac OS X 10.6 “Snow Leopard”, installing Ubuntu is a good choice if you want the latest software, want to stay secure and don’t rely on Mac-specific programs. (It is possible to dual-boot or keep one...
I recently installed Ubuntu on a new machine and wanted to bring along my music collection to use with Rhythmbox. This was trivial, I just copied the Music folder from my old machine to my new via an external USB hard drive and let Rhythmbox on the new machine search through the folder at first run. Then I wanted to...
Lately, I have been looking a little at a sonata by Telemann for the treble viol in G major from Der getreue Music-Meister. Often, on the treble viol, a practical challenge is that a lot of music is ascending quite high, but in this piece everything keeps moving on the lowest strings in stead. The music actualy descends to c#,...
I have recently installed Debian Wheezy with LXDE on my netbook. As anticipated, there were a number of things that needed to be done to get it to work as I like. Debian is a bit more work than Ubuntu, but also slightly lighter on resources, and I enjoy learning how to do this stuff. Having used some time to...
I usually keep one or a couple of similar programs running at each desktop. On the Mac, I use 9 Spaces that I alt-tab or ctrl-arrowkey to and from, but when using 4 desktops in LXDE on my netbook, alt-tabbing doesn’t show me all my programs, but only the programs running on the current desktop. Of course, I could alt-scroll...
Tap to click is usually on by default, but I know that I am not the only one that disables it on all my computers to avoid clicking all over the place. In most desktop environments (Unity, MATE, Gnome, KDE..), the Mouse and trackpad system settings panel lets you turn off tap to click, but in LXDE, there is no...
I have made some web pages dedicated to the Macintosh Quadra 700 (on the Quadra itself). These contain some technical information about the machine, suitable software, some how-tos and such. Since the pages were written in HTML on the Quadra itself and I wanted to make them readable with System Mac OS 7 and 8 compatible browsers, they do not...
