The Haunted Calculator

Every morning, for the past few months, I've needed to use a calculator. The calculator in question is a vintage early-1980s model Sanyo CX 2630 solar powered beast. You can read about its awesome functions at these two extremely nerdy websites: calculator.org and mycalcdb. It has all the functions you'd expect of a calculator, not the least of which is that being solar powered, it hasn't required new batteries since the Red Hot Chili Peppers released Under the Bridge. As an aside, it delights me to no end that there are websites dedicated to the minutiae of vintage calculators. The internet is a haven for anoraks. This particular calculator has issues, though. It adds just fine. Subtracts perfectly. It even handles multiplication and division with aplomb. While I haven't needed to use the function, I have the utmost confidence in its ability to calculate a square root and store the results in its memory. The thing that worries me about this calculator is

THE FREAKING THING IS HAUNTED.

Tucked away in a dark drawer, devoid of fluorescent "solar" power, its twenty year old batteries fail, and it loses its mind. Grasping at the last vestiges of its consciousness, it types a garbled message, leaving it on the screen for me to wonder about the next morning.

I've kept a log. Every time it's left me a message, I've recorded it. The original purpose of this project was simply to see if it was ever the same. Was the message similar, day in and day out? Was it just random crap? (Hint: probably!) Was there a hidden logic?

I'll let you decide. Big gallery to follow, with commentary. Hit the jump.

Vintage photo effects

I've been screwing around with various "vintage effect" iPhone apps, including Hipstamatic, Instagram and a few others of significantly lesser quality. I've started to form the germs of opinions about these apps, and I'm going to attempt to put those opinions into coherent sentences. First, lets explore the apps.

Hipstamatic is an "emulator" of the Hipstamatic 100 camera, a possibly fictional camera that sold very few units in the 1980s. Functionally, it's the equivalent of an Instamatic hand-held camera.

The software includes a bunch of effects in the guise of "films", "lenses" and "flashes". Additional effects can be purchased for a nominal fee.

Films give a range of grain, border and colour effects. Lenses give depth of field (faked, of course), focus anomalies and light leaks. Flashes overlay a coloured gel to the image, while also invoking the iPhone 4+'s built-in LED flash.

These three classes of effect can be used as intended, or mixed and matched by means of your own preferences, or random chance. Shaking the unit mixes all three effects randomly, leading to the need to take each photo several times, shaking between, to ensure you don't snag one of the myriad less desirable combinations of effects.

And oh, yes indeed, they can be undesirable. Horrific combinations can be achieved by combining lens and film effects centuries apart in design. The 1990s film that borders your image with coloured sellotape is particularly horrifying, coupled with an antique Tinto lens it's truly ghastly. Tri-coloured flashes are atrocious. The Salvador Dali film and lens combination is designed solely to pop up occasionally and make you swear loudly as it ruins otherwise good photographs with its peculiar overlaid effects.

An utterly rare example of the Salvador Dali effects actually contributing to an interesting image, rather than ruining it like vinegar on your breakfast cereal.

Instagram is a different animal entirely, geared primarily toward image sharing. The sharing engine -- recently bought by Facebook for one gazillion dollars and the subject of much privacy concern after a misread alteration to its terms of service gave the allusion the company would sell your soul with your photographs to the nearest punter -- is not the part I'm concerned with today. The effects and filters, though, are.

Like Hipstamatic, Instagram offers the ability to whack on a bunch of effects. The image border and overall colour alterations are handled within a single "film" option, with about twenty different choices at time of writing, with the option to kill the border, auto-enhance the image and apply circular or "tilt shift" depth-of-field effects.

As a result of the way they're constructed, both of these apps have a different effect on your photography. Hipstamatic places the quality of your end result largely in the hands of the Gods, while Instagram gives you the ability to rub various kinds of funk on an otherwise ordinary image to make it look good enough to pollute your friends' Instagram feeds.

The issue I have with these apps is that they tend to remove the onus of responsibility from the photographer, instead allowing the person pressing the button to either blame the filters and effects for ruining an otherwise decent photo, or entirely taking self-credit for a stultifyingly boring image enhanced pointlessly with vintage funk sebum.

I once owned an Olympus point-and-shoot camera, a mJu-300. It was awesome. I actually used it to take some of my earliest lightning photographs, many of which were perfectly cromulent photographs. The camera's functions were so minimal that the only way I could take photographs of lightning was to set the camera to "party" mode, so it was expecting dark environments, turn off the flash, and hope that the ambient light was dull enough to allow it to expose for a full four seconds. I had no ability to control the aperture (f-stop) or ISO. (Although in hindsight, the little bugger of a camera had a minimum ISO of 80, which would be splendiferous on a DSLR.)

Many of the photographs I took with it, however, were not so great. This little camera gave me a super power, though: I could blame the camera. I had no controls to mess with. I had no options that could improve the image. While I could always criticise my skills in Photoshop, there was no way I could have produced more information in any of the photos I took, because there was literally nothing I could do to make them "better".

Hipstamatic and Instagram are much of the same. They're a point of blame, and a source of false credit. They're cool, don't get me wrong. Many of the images look awesome. I'm really fond of the recently released Tintype set, with daguerrotype and colourised tintype films, which look amazing. I'll also continue to use them, simply for the virtue that they tend to make otherwise boring photos interesting.

Daguerrotype effects on an appropriately vintage subject actually look pretty cool.

I'm going to make a concerted effort never to feel pleased with the result of a Hipstamatic or Instagram photograph, though. It just doesn't seem right.

Heroes of Science

In November, I created an image called "Heroes of Science Action Figures", in which I digitally altered some Star Trek action figures to resemble famous scientists. It went a little bit viral, and has (to date, Jan 2013) some 230,000 views on DeviantART.

I've since created a "sequel" to this image, featuring all of the original scientists (with Neil deGrasse Tyson now sporting his famous Celestial Vest), plus an additional 26 new heroes. I managed to fulfil a few requests, included a few more female scientists to offset the alarmingly testosterone-laden original image, and squeeze in another couple of my own personal heroes of science.

I also created a FAQ page for the project, answering in tedious detail a bunch of questions and criticisms the graphic has received.

As an added bonus, here's the 27th new figure. I created the image of a Yuri Gagarin action figure before I made the decision not to include anyone who was involved in the space race/space age/space program. The reasoning behind this was entirely practical: it opened a gigantic can of worms, and I would have no choice but to include another fifty figures to do the space era justice! Maybe one day I'll make another graphic specifically for that task. :D

Yuri Gagarin, the first human being to enter outer space. You can read about him here!

Blocked telephone numbers, and the not answering of them

PhoneInAdelaide.jpg

There seems to be quite a strong mentality these days that one shouldn't answer phone calls that come from blocked numbers -- that is, phone numbers with their caller ID suppressed. I find this interesting. I did a bit of Googling, and I've discovered heaps upon heaps of people who refuse to answer them, often on entirely vague or misguided grounds. I have a number of plausible theories for why people do this, some of which can be combined together: 1. They're expecting bad news. Or they owe money. While it's probably better to answer a telephone call from a debt collector than have them come knocking on your front door, I can at least understand the logic behind avoiding the call.

2. In the '90s, prior to the ACMA Do Not Call Register being introduced to Australia, there was a strong predilection for telemarketers to use blocked numbers when calling. A lot of these companies would also employ computer systems that would automatically dial from lists of numbers, confirming a number's validity when someone answered. These culled lists of numbers-that-get-answered would then be sold on to other telemarketing companies for a sizeable profit. Since the introduction of the DNC Register, it's illegal for telemarketers to call, period, let alone use blocked numbers. That's not to say that a scad few don't choose to break the law and call anyway, but the odds have reduced significantly. Charities and other organisations that are immune to the DNC Register are required to have their numbers visible to the receiver, so that removes them from the equation.

3. Psycho exes, drunk friends, whatnot. You can opt for your own telephone number to be made silent/blocked/private. Some handsets differentiate between blocked numbers and private numbers. Dialing 1-8-3-1 before the recipient's number will temporarily make your Australian phone number into a blocked number, so it's entirely possible to prank call people in this fashion without having a prior arrangement with your telco. In the scenario of these types of calls, I can once again understand the decision to not answer.

There are another couple of things I'd like to add to this inconclusive report:

• Many businesses, particularly doctors and large agencies (to give only two examples) use blocked numbers for a perfectly practical reason. Doctors want to be able to contact their patients to deliver news or test results, but they don't need the patient to be able to call them back on their own personal desk phone with every little itch and malady. That's why there's a receptionist and a system to make appointments. Agencies with call centres use blocked numbers because their staff are often trained in specific tasks (such as performing a data fix on client accounts, for example) and only need to contact the public for specific information. There is no reason that the recipient of the call should ever need to contact the staff member again, because the staff member is not trained to help with general enquiries. It would be a waste of the company's resources to make public the staff's individual extension numbers, because the phones would then be ringing with calls that could not be acted upon by those answering them.

• "If you need to contact me, I have the right to know who you are". Fair enough, but why don't you ask them when you answer the phone? If I was calling from a number that you wouldn't recognise, what would make you answer that number in contrast to no information at all? You can always hang up.

My work calls me from blocked numbers. That's a pretty good reason to answer them. But maybe that makes me unique.

Ring ring.

Follow-up, August 2013: Answers to common search queries relating to this article:

Question: why shouldn't i answer calls from blocked number Answer: There is absolutely no reason why you should avoid answering calls from a blocked number. (Provided you're not avoiding a stalker or dangerous ex or calls from a utility company that wants your money in exchange for a service they've already provided you. In the latter case, perhaps you should just pay your bill. Or arrange a payment plan. Something like that.)

Meanwhile, on Planet Plastic

There are so many things in the world that are inevitable. Like the Mayan apocalypse. And talent shows. Wow, do I hate talent shows. Also, action figures. Heroes of Science Vols. I & II went nuts, so it's to be expected that I'd make more. I figured it'd be only right to make one of myself. So here it is.

Collect all one of them!

The purpose of the thing is to act as a "deviant id" on DeviantART, identifying me to other DA users in a trendy and interesting way. I used to have a fake railway ticket serving the same purpose.

Enjoy.

50mm lens experiments and shenanigans.

Decided to do some hands-on tests so I could see for myself the difference in crop factors and lens quality between the Olympus OM 50mm f1.8 and the Canon EF 50mm f1.8 II lenses. This post contains a lot of images and may be boring if you're not into camera lenses and pixel scrutinising -- hit the jump if you're interested in the results.

These shots demonstrate the difference in crop factor (focal length multiplier) between the Canon APS-C and Olympus Four Thirds sensor sizes. I've scaled the bottom image down to the same "size" as the top one, clearly demonstrating the difference between the Canon (1.6x) and Olympus (1.84x) crops.

Never realised how much was actually lost using a Four Thirds sensor.

Two shots from the Olympus E-510, comparing a 50mm zoom on my telephoto lens (the only other lens I have capable of a 50mm focal length) and "50mm" on the old OM legacy lens.

When I first bought the old OM lens and adaptor, one of the things I had read about was a considerably different focal length resulting on the 4/3 cameras, but this demonstrates that the difference is actually quite minor.

Yes, I realise the top photo is overexposed.

Olympus vs. Canon 50mm f1.8 lenses.

There's a lot of criticism of the Canon lens for having pretty nasty bokeh (out of focus areas) because of its five-bladed aperture, but all in all, it's not too bad, in my opinion. The OM lens loses some sharpness, which is to be expected, but I think I still prefer its result. I find that the Canon 50mm tends to get less pronounced glowing edges on the highlight hotspots.

Same test, same lens, different aperture. Reduced to f4.0, the Canon EF 50mm's bokeh looks significantly nastier than the Olympus OM 50mm's, at least in my opinion. There seems to be a tiny bit of light leaking around the aperture blades on the Canon, making the corners of the highlight hotspots quite harsh, really accentuating the five aperture blades. At the same camera settings, the Canon's image at f4.0 is undoubtedly sharper, though.

Direct comparison between the Olympus and Canon 50mm lenses. All in all, the difference for this kind of image is pretty insignificant. Auto white balance seems to have thrown a yellow cast to the Canon photo.

OM, pros: - $50 from Ebay + $5-$35 for adaptor - More pleasing bokeh. - Quality construction, from the days where stuff was made properly, ergo: sturdier lens. (Lens mount/adaptor, not so much, though) - Very trendy

OM, cons: - Adaptor is atrocious, but for this I can blame someone on Ebay from Hong Kong - Image slightly less sharp than Canon - No auto focus function

Canon, pros: - $90 - Auto focus - Sharper image - Ludicrously lightweight - Adaptor not required, obviously

Canon, cons: - While autofocus exists, it sounds like it's grinding up Legos inside there - Very cheap construction; very cheap lens

Overall, I think I still prefer the Olympus OM 50mm lens. The Canon one just seems utterly disposable in comparison.
