I'm probably going to get a new Nikon digital single lens reflex (DSLR) camera. You know, those big cameras that let you attach different kinds of lenses. Even though I got a new regular point-and-shoot (P&S) camera this summer, and my iPhone also takes very nice pictures. So why another DSLR?

This is a post about the aspects of DSLRs in general and the Nikon D7100 in particular that those of you who haven't used a modern digital single lens reflex camera may not know about.
My new Nikon D7100 has a 24 megapixel sensor. I shot some test photos at 24, 13.5 and 6 megapixels with low, medium and high compression to see what the tradeoff between image quality and file size is. Have a look at the results.

I originally planned to get a D3200 or a D3300, which are part of Nikon's entry level DSLR lines. But I couldn't resist the extra features that are part of the more advanced D7100. One of those features is that you can use very old lenses that don't have a built-in CPU. So with a small adapter ring, I was even able to mount my 35-year-old (give or take a few years) Pentacon 135/2.8 135 mm f/2.8 lens, also known as the "bokeh monster".
As you may know by now, there's an oil rig 12 km off the coast of The Hague. 12 kilometers is pretty far away, so it's not easy to photograph. Even with a long zoom lens it shows up pretty tiny:
I have an old Philips 31CT "computer flash". No, it has nothing to do with computer memory—it's a flash unit that sits on top of your camera. And although calling it a computer grossly overstates matters, but it has a small amount of automation built in that allows the flash to measure the amount of light returning from the scene that's being illuminated, and actually stop flashing mid-flash once a proper exposure has been accomplished.

After yesterday's experimentation with my old "computer" flash unit, someone on the dpreviews forums suggested that maybe I was getting bad exposures because the flash was a bit too slow for the D7100's 1/250 sync speed. So I set up a little still life to take some more test shots.

When Nikon announced the D3300 camera along with a new version of the 18-55 mm entry-level kit zoom lens, I got somewhat excited. One of the things that I don't like about DSLRs is that they're so big and heavy. So having an even smaller and lighter version of Nikon's already smallest and lightest zoom lens really appealed to me.

Great TEDxTalk video. As expected, what's sold as the "paleo diet" today has very little to do with how paleolithic people actually ate.
Also, it's important to remember that even with all the issues we have today, we still live longer than any previous generation, so how does it make sense to start eating like people who all died much younger than we do today? Not to mention that it's probably impossible and certainly not a good idea for our environment for 7 billion humans to eat enormous amounts of meat.

Today we had city council elections in the Netherlands. In an effort to stave off historically low turnouts (predictions were less than 50%) many cities use various gimmicks to attract voters. Here in The Hague it was possible to vote in a historic bus and a historic tram (streetcar), 50-year-old PCC. I went out to take some photos and a video. The first ones were at the kerkplein ("church square") where the stemtram (voting streetcar) looked a bit lost between the old, big church and the old city hall building (with the tower), especially as there were all kinds of trucks parked around the church, apparently there's a big event there.
In Den Haag had de gemeente een historische stembus en stemtram ingezet om kiezers te lokken. De stemtram is een PCC uit 1964. Ik was als eerste gaan kijken en wat foto's maken op het kerkplein, waar de stemtram er een beetje verloren bij stond tussen de grote kerk en het oude stadhuis, vooral ook omdat er allemaal vrachtwagens stonden om blijkbaar een evenement in de grote kerk op te bouwen.

Reading Bruce Schneier's blogpost on the heartbleed bug:
I'm hearing that the CAs are completely clogged, trying to reissue so many new certificates. And I'm not sure we have anything close to the infrastructure necessary to revoke half a million certificates.
Wouldn't it make sense to simply invalidate update SSL implementations to reject all certificates that predate the discovery of the heartbleed vulnerability? Even if all the the potentially compromised certs are added to revocation lists, most clients don't check for revoked certificates, leaving a huge opportunity for man-in-the-middle attacks using the compromised certificates.

The other day I had a discussion about whether to use the "standard" sRGB color space or a larger color space for my digital photos.
If you have any interest at all in using older Nikon lenses, you probably have some understanding of the difference between non-AI, AI, AI-S, AF and AF-S lenses. The trouble is that places on the web that explain the differences easily get lost in the details. This article is intended to serve as a slightly easier to digest version of the story.

I started taking photos in the 1980s. I still have a bunch of black-and-white negatives that I developed myself, but never got them printed. In addition to that, I have color photos with their negatives and slides. The past years, I've been looking for a way to digitize all of these. The number of photos isn't huge, maybe a few hundred, but having a service do it at 50 cents or so quickly adds up. Turns out that some flatbed scanners have a transparency attachment so you can scan negatives and slides. The Epson Perfection V370 Photo scanner has a transparency mode built in. It gets pretty good reviews and only costs about € 80 or $100. So I got one.

Good piece on the misguided efforts to get adults to wear helmets when riding a bicycle.
Here in Holland adults on regular bikes (as opposed to racing bikes) virtually never wear helmets. I've never heard of anyone falling off of their bikes on their heads.
I've cycled 8000 km last year myself, and I can think of very many things that would make the roads safer for cycling, the first of which would be to, you know, look at the traffic around you. Helmets would be very far down the list.
I got some flack for always listening to podcasts or music when cycling, but I don't think that's a problem. I keep the volume low enough that I can still hear car horns and I'm very careful about looking in all directions, including behind me, which many cyclists don't. I had two minor collisions the past year, in both cases because another cyclist turned left unexpectedly as I was passing them.

Since I got back in the SLR game, I got some additional second hand cameras and lenses. As a result, I'm now the owner of no fewer than five 50 mm lenses. (Well, four 50 mm and one 55 mm.) So I decided to compare them. First an overview, then some testing!
Earlier this week I got myself a Nikon F65 camera. The F65 is a single lens reflex 35 mm film camera that Nikon sold from 2001 to around 2005. You can get these second hand for next to nothing these days...

Last week, I wrote a review of the Nikon F65 camera. Although the F65 is more than a decade old, it supports most of the photographic automation that we're used to with our digital cameras. The F65 left me wanting to go even further back in time, so this week I'm going to explore manual focus photography with a Nikon FE SLR and Nikon AI and AIS lenses on my current Nikon D7100 digital camera.

Hoewel ik het na de drukte van vorige week eigenlijk wel gezien had voorlopig, kon ik het toch niet laten om gister nog wat plaatjes van oude trams te schieten, maar nu zit wat mij betreft het oudetramfotografieseizoen er wel op.
De reden om toch gister nog op pad te gaan met de camera is dat er nu oude trams over de route van lijn 9 reden, wat bij de normale ritten op zondagmiddag niet gebeurt. En de route van lijn 9 wordt binnenkort onder handen genomen om er straks de bredere Avenio's (zie foto's vorige week) over te kunnen laten rijden. Dus misschien was dit wel de laatste kans om de oude gele PCC's te zien rijden als lang geleden toen ik met tram 9 naar school ging.
I've been experimenting with shooting film a bit recently, which gives me that nice retro feel. And nothing is more retro than shooting black-and-white film. So let's compare the results to the black-and-white images current cameras produce.
In addition to using some classic Ilford HP5 film (well, Ilford HP5 Plus these days), which is very similar to Kodak Tri-X, I also wanted to try out some chromogenic film. Chromogenic film is black-and-white film that is developed using the same C41 process that is used to develop regular color negatives, so you can have it processed pretty much anywhere.
I've been doing a lot of reading and Youtube watching about nutrition the past year or so. So I've seen all the scary numbers about the increasing obesity levels in the United States (and elsewhere) numerous times¹, and seen all the speculation about the reason why Western populations started getting so much heavier the past decades.

Tonight is the third night of the Scheveningen International Fireworks Festival! Hopefully the rain will be done by then. Photographing fireworks remains tricky business, though.
That was fast. No sooner had I complained about my iPhone 5 battery:
When I got my iPhone 5, I did a bunch of battery tests, and at that point, the battery life was pretty much identical to that of my iPhone 4, which was two years old by then. However, pretty soon I started having issues where the phone would shut down if I tried to do too much at the same time if the battery was below 50%, especially in cold weather. (Taking a photo would typically do it, as that fires up the GPS which in turn causes cellular data traffic.) It took me a while to figure out that five minutes later, I could turn the phone back on. These days, I have to be very careful with the way I use my iPhone in order to make it last through the day on a single charge.

Vandaag hield het Haags Openbaar Vervoer Museum weer z'n tweejaarlijkse PCC-dag.
Many people's first take on the iPad was that "it's just a big iPod touch". And so it is, really. But sentiments changed quickly as sales numbers skyrocketed: the king (the computer) is dead, long live the new king (the iPad). But then iPad sales numbers went down for two consecutive quarters. While Mac sales were up.
There are of course many possible explanations: iPads aren't upgraded biennially like phones, but rather every three years or longer. Apple's prices are too high. Competition from cheap Android tablets.
Software on the iPad doesn't seem to do very well, either, which has its own issues, but I think the real reason for lack of both hard- and software sales is that the iPad simply isn't as useful to as many people as industry watchers thought...

NFC is an amazing technology. Mark my words: it's going to be huge. Whether Apple adopts it next week or not. The reason: it ties together the physical world with the networked world. When scanning for Wi-Fi networks or bluetooth devices, it's really hard to know which names on your screen map to which devices in the real world. So Wi-Fi requires typing long and complex network passwords and bluetooth uses an annoying pairing procedure. NFC, on the other hand, really is plug and play. Without the "plug" part.

I even mention NFC. Having NFC in a watch or wrist strap would be very convenient when it comes to making contact with a reader, but unlike iPhones, I don't think an iWatch would have a fingerprint sensor, as there's no room to put one on the device. Well, on the strap maybe. And the fingerprint scanner is what would make NFC payments so much better than current payment systems.

The Casio F-91W is a great watch. It's cheap (I paid 15 euros) and simple. It weighs 22 grams. The best thing? The battery life is seven years. Casio started making them in 1991, and they're still selling in good numbers, according to this somewhat incredulous story over at the BBC.
I do have to admit one of the reasons I got the F91W is to see if I could get used to wearing a watch again in anticipation of the Apple Watch.

I've pretty much decided to skip the iPhone 6 and stick with my iPhone 5 for another year. One of the new features in the iPhone 5 two years ago was LTE or 4G. But sadly, even though I kept my eye open for it when roaming internationally, I've never seen "4G" in the status bar of my iPhone 5.
After the Netherlands implemented net neutrality in 2012, prices for mobile data went up a lot, but I'm grandfathered into a cheap unlimited plan from KPN that I'd have to give up to get LTE. Also, KPN uses LTE frequencies that the iPhone 5 doesn't support, so I'd have to switch carriers.
So what I did instead was get a prepaid SIM from Vodafone NL...

In iOS 7, lots of stuff turned white. Such as the Music application, which you use to play music. That's unfortunate, because the album art embedded in songs looks much better on a black background than it does surrounded by white. However, the lock screen, which also shows album art if music is playing, is still dark.
The problem here is that for non-square album art, the image is made square by "letterboxing" it with white borders on the sides or the top and bottom—a real eyesore (As far as I've been able to tell, art work for music on the iTunes store is always square and actual (vinyl) album art is also square. However, CD boxes aren't quite square.) Fortunately, we only had to suffer this indignity for a year, as the iOS 8 update released last week fixes this.

Jean-Louis Gassée over at Monday Note has an interesting article talking about how cameras used to last for decades back in the analog days, while they're obsolete within a year or two now that they're digital. And how the same thing is about to happen to the watch: an old mechanical watch will keep doing its thing for decades (I'm assuming some upkeep here), but not so much for an Apple Watch:
There’s no carrier subsidy for the AppleWatch. That could be a problem when Moore’s Law makes the $5K high-end model obsolete.

I wasn't even sure I was going to get the new iPhone this year, even though I've been upgrading iPhones every other year until now. I liked the long battery life of the iPhone 6+ as well as the 1920x1080 screen—until it turned out that Apple uses some weird scaling tricks rather than the native resolution. And I wasn't sure I could handle the size and weight of the 6+. The 6, on the other hand, didn't seem to come with any must-have features. And maybe it's silly, but the notion of having to replace my iPhone 5 cases and its dock also made upgrading significantly less appealing.
But then the sleep/wake button of my iPhone 5 started to act up, and after the earlier battery replacement, I started to doubt whether I'd get another year of good use out of it. So I got the black space gray 64 GB iPhone 6.
