In Portland right now, catching up with Jen + Chas :)

For the first time since, like April, we're going to the US next Saturday for 5 days.

- Sat - Aviation Geek Fest 2010 at Boeing Factory, with VIP tour of factory floor (not viewing gallery). My tweep at the Boeing Factory suggested it when I mentioned planning a visit for Sunday. Heh. Thanks Sandy..
- Sun - Seattle to Portland, probably via Museum of Flight at other Boeing Factory.. see velithya and myfyr(!) + twins
- Mon - Portland - maybe catch up with nightbird
- Tue - Portland
- Wed - Eugene - see tygati

At least I think this is the plan. Liz is sleeping right now..

Before we go, the Prius needs a service.. the rear left regenerative braking system is squeaking, and it's been 6000kms since the last oil change, and 150,000kms since the last transmission fluid change (normally you either change after ~50k or never change least your clutch plate explode, but apparently not an issue with the continuous variable transmission in the Prius..). Shouldn't be too bad though. This will probably also be the first time the Prius has been to the US, since it spent the first bit of its life as a fleet car for a Canadian telco.

We're going to be in Perth from about December 21st 2010 - Jan 6th 2011. We then are flying up to Singapore, spending a few days there, then flying from Singapore to Vancouver on Jan 11th.

The flight has a 12 hour stop over in Tokyo on Jan 11th, which will be fun, and hopefully we can catch up with a friend who will be there then. Regardless of it we can or can't, it'll be nice to go to Tokyo again, if only for a short while. I don't know if said friend has mentioned their trip publicly, so I shan't say who.

Good to get the "big" flight booked. Now we need to book a Jetstar flight to Singapore from Perth, and see about travel insurance. Which will be.. exciting. Since we need it for the time we'll be travelling to Perth, until we get back to Vancouver, while our tickets are technically Singapore to Vancouver returning later in the year.. but while in Vancouver, we have other insurance. Arg, usury!

With last Friday being my birthday, I felt like getting a present for myself. I had been looking at a macro lens, but with winter coming, I don't see much use for it immediately. Also a Canon 60D body, but they're not out yet. Also an iPad, but there's a better one coming in Jan, and one of my co-workers offered to lend me his for the time we're in Australia, which is when I really wanted it.

So my mind turned to a graphics tablet. But they ain't half expensive. Usually. I did some reading, and some craigslisting, and found someone selling an 12x18 inch one (30x46cm, for those in metric countries..) in not so great condition for $90. But it had problems - wasn't in great condition, was serial port only, part of the cover sheet was bent, and it was old ("Works with Windows NT 4!").

Bought a USB to Serial adaptor for $11, got a GPL driver to use serial Wacom tablets with OSX, cleaned up the case a bit, flattened the plastic sheet using a hair dryer, and hey presto, I have a giant graphics tablet. You can still buy 12x18 inch Wacom tablets (unless you're in Quebec), but they're over $1200 with tax. I'm not sure what I'm missing either - this one has angle and pressure sensitivity, just like the new ones, and connects via USB, just like the new ones.. :)


Word of advice: This is actually almost TOO big. But if I find a 4:3 21 inch LCD, I could make a DIY-cintiq.. hmm :)

Here's a random sketch of a bathroom I did:

What is love?

Baby don't hurt me, don't hurt me no more.

It's a tough one. Love is caring about someone else, and accepting them with flaws and all, as they accept you with yours. It doesn't have to be in the context of a relationship, but it can be. Love is not sex, and sex is not love.

I love my wife (♥ lizbyrd :) I love my parents, my grandma, my uncle R and aunty O. I even have a few friends who I would say I actually love.

I don't have a definition of love in great detail, but much like art, I know wot I like, and I know it when I has it.

So one of the people here who used to do Systems Administration here was very old school. Install into 5 partitions (/ (1G), /usr (4G), /var (4G), /home, swap..) and make them all as small as humanly possible, and put the rest of the space into /local (65G), and put everything into there.

Which is all well and good, except things like, say, Redhat up2date, want plenty of space free. Today's fun:

- Break HW RAID mirror for backout plan
- Register system with Satellite server..
- Fail because it doesn't have the SSL certs for our Sat. server..
- Add certificates
- Register with RedHat Satellite
- Try running update
- Fail because of lack of HDD space
- Resize down /local
- Resize down LVM LV..
- Resize down LVM PV..
- Edit partition table to decrease PV partition size
- Create new partition (since existing partition with space in was in wrong VG..)
- Create PV in new partition
- Add PV to other VG
- Extend LV
- Expand filesystem, and find it fails due to old resize2fs
- Find ext2online, use that instead
- Right, now we have enough space, let's see what happens when we run up2date for the first time in ~3 years
- Amazingly, it works!

Yay Linux :P

Sunset has been pretty awesome lately, but it is really getting earlier. Setting at almost 9:30 at night, instead of 10:30.



In somewhat sad news, it seems there is some dust inside my 100-400 lens. I have no idea where though, it's not on the front or back elements. Apparently the trombone design sucks air+dust in and isn't so great about blowing the dust back out. Thankfully it's in a corner of the image (which would mean it would suck on a full frame camera.. hrms..) and it only shows up under certain situations.

I tried taking some test photos at both ends of the range, and it wasn't in some of them, and it was in some others. As cleaning the lens is $299 from Canon, I'll wait till it becomes a real issue. Still happy with the lens, and I bought it in knowledge that this could happen to it, but I'm still annoyed it did, as I thought I was being really careful about it.

Of course, the pic embedded is unrelated, and was taken with my 17-55 f/2.8IS lens, which takes awesomely sharp images.

Also unrelated to a 400mm lens, my flash reflector arrived from China. Worth both dollars I paid for it, will have some fun on the weekend.

iBook with built in iPad with iBooks on it

(or: Yo dawg, we heard you like iBooks, so we put an iBook in your iBook, so you can read while you.. read?)

A simple question asked by an online acquaintance of Elizabeth. The answer is: it depends on what you think makes a good picture.

Photography as an art is about making an image of a scene in such a way that it evokes an strong emotional response from the viewer. There are many ways to achieve this, and a point and shoot camera need not stop you from being able to do so.

For example, this photo of a passionfruit is one of my favourite photos I have ever taken. Partially, it's because I like passionfruit, but putting that aside, it has good lighting, sharp focus, nice colours, and even a nice background blur. And I took it in December 2001 with a camera I had owned for less than 48 hours, that wasn't a digital SLR. My only criticism of it is that it is in 4:3 ratio, not 2:3 ratio. Even if the camera doesn't support 2:3 ratio photographs, try imagining the top and bottom of the photo will be cut off, and you can do it in post production..

I took 6000 photos with that Canon G2 over the next 5 years (even though I paid $1990 for the camera, I think I got my monies worth, and it's still going strong with my Dad), and eventually discovered it had one weakness - really really really poor handling in low light - it would put about 14 vertical bars through any short shutter speed low light situation. Back in 2001 when I bought that camera, there were a lot of crappy cameras on the market, even from companies like Sony. But today, in the right conditions, any modern name brand digital camera can take a great photo. The question is, what is required to make a nice image like that one?

The easy answer is light, and lots of it. Either natural (preferred) or from a flash, or from an external light. The quality of the colour is based on the type of light. Natural light is very wide bandwidth, so is nice for photography. Flashes are also pretty wide bandwidth, as are studio lights. Problem comes from home lighting fixtures, especially compact fluorescent ones, which are somewhat narrower, leading to colour reproduction problems. You know how some parking lots have lights that make everything look yellow? Well, think of poor quality lighting like that - the human eye + brain generally doesn't notice the smaller gamut, but the camera will, and may try to correct colours, with varying levels of success.

Flashes are nice, but not generally pointed directly at what you want to photograph. This is where point and shoot cameras have a problem, since their flashes generally point straight ahead. You want the light to be softened, and coming from all directions (maybe pointed in one surface specifically, but you will often still want it in other places). The way to do that is by using bounce flash. My usual trick is the reverse ceiling bounce with my digital SLR + external flash. Point the flash backwards and upwards over your head, and towards a white surface. The light reflected will be diffused, and look nice. Like this one.

Some non digital SLR cameras take external flashes. If nothing else, if you want to take photos indoors, I would recommend getting one of those, and an external flash. Be aware that the flash may cost as much as the camera, but it'll be worth it, and still probably cheaper than buying a new digital SLR.

So, light = good, and good light = good colour.

Focus is generally pretty easy to deal with - every camera or lens will have a minimum focus distance stated somewhere. Do not try to photograph closer than that, and the camera will probably take care of it ok. In my camera, I have it set to auto-focus on the centre point only. I focus by holding the shutter button down part way till it focuses and gets light levels right, then while still holding the button down, recompose. On the subject of composition, the rule of thirds is pretty twee, but not a bad starting point.

Background blur (or bokeh) is a little harder to manage, and is another area where digital SLRs can help. Camera lenses have a depth of field, or how deep something is in focus.. closer or further away and it'll be blurry. This is a function of aperture and how far away from the subject you are. Lower aperture number = physically larger aperture = smaller depth of field. Physically larger aperture = more light gets into camera, and as we recall, light is good. So you can do it two ways.. either have a low aperture lens, or move the background further away from the object (or vis-a-versa).

Point and shoot cameras will often have higher apertures, meaning bigger depth of field, which makes it easy to get everything in focus, which is the first thing many people will notice about a photo. They're also easy to build, since the size of the internal diameter of the lens can be smaller. For example, Elizabeth's P&S camera has an aperture range of 3.2 - 5.8, which isn't bad, but isn't great either. My nifty-50 lens has an aperture of 1.8, which means it can take photos in reasonably low light. For insane sums, you can buy 1.0 and 0.95 lenses, which combined with a good camera, will let you take photographs using candles as lighting.

You can make up for a camera that is less sensitive to light by increasing the shutter speed, but past a certain point the photos will blur because the camera or the subject will move. A longer shutter speed also won't help with aperture or background blur. A tripod can help here if it's going to be the camera that moves, but not if it's the subject. To make up for cameras moving, some point and shoot cameras and some digital SLRs have image stabilisation, which uses gyroscopes or adaptive optics or both to keep the image fairly still even when the camera moves. Then you just need to worry about the subject moving..

Which gets the to crux of the question - digital SLRs vs point and shoot cameras. You for the most part, get what you pay for. How much do you want to pay and what do you want to get? Find the intersecting point, and buy that. If you can't find that intersection, change your price point or your desires, or wait a while.

What makes a camera cost what it does - what's the difference between a $20,000 Hasselblag H4D medium format camera, and a $120 Canon A480? Sensor size is one of the keys. Bigger sensors = larger pixels = more light gathered per pixel per second = less noise. They often try to express this as ISO light sensitivity. Small sensors make up for this by running more electricity through the sensor to detect light, but at the trade off of having a more grainy image. They deal with the grainy image by having in-camera noise reduction, that essentially blurs the noise away if it's too bad, or by taking the photo with a high enough megapixel count that when printed or scaled down, you're not going to notice it. A bigger megapixel number, like the megahertz myth of computers, gives an easy number for the uneducated to compare and base decisions on, but it's not that important. As long as it's over 6MP and you don't want to print giant posters, it's all good.

The other cost input is lenses. Point and shoots have small non-interchangeable lenses which don't let in much light, but they're cheap to make. Digital SLR lenses are bigger, heavier and thus more expensive to make and distribute, but they make some that let in a lot of light, so they have that going for them. Also, being inter-changable, they don't have to be a "jack of all trades, master of none", but you can buy digital SLR lenses that are. 

So what should you buy? Digital SLRs are big and bulky, and relatively expensive, but it's easier to take nice pictures with them. Point and shoots are cheap and can take nice pictures, but it's harder, and you will eventually reach a point where your creativity will be limited and there's nothing you can do to help. If you want a digital SLR but have sticker shock, consider secondhand ones. Anything from 2006 onwards from Canon or Nikon is a good option. Take a photo of a white wall and look at it up close in an image viewer - see if there is any dust or dead or bright pixels. You'll know them when you see them. Even those don't make it a walk away deal, just something to negotiate on. 

If you can't buy a digital SLR, but you care about making nice images, buy a Canon G11. It's a point and shoot with a lot of features from a digital SLR, including support for external flashes. It has a larger than average sensor (and in the most recent revision, grom G10 to G11, they actually decreased the megapixel count, to make a better sensor), a larger aperture range (2.8 - 4.5), and it doesn't cost the earth (like my Canon G2 did back in 2001..). 

So that's my thoughts on the question "Can I take good pictures with my point and shoot digital camera?" .. what are yours?

Some of you may not have seen this on Facebook/twitter, but after much discussion and thinking about moving, etc, we bought a car - a 2005 Toyota Prius - in white.

We've done 400kms since thursday on it. The novelty of having a car is still new. It's got 4.9L/100KM (48mpg) so far, so my daily commute of 33.2km will use ~1.6L of fuel, which at current rates is $1.82 per day.. so 21 days work per month makes it $38.26 .. plus $70 for a parking pass... and.. wait for it.. $370/*month* for insurance and registration (to be reduced to ~$230 when I get some paperwork from SGIO).

Before I go on about the car.. let me rant about the insurance/rego some more. BC has this company called ICBC. It's government owned, but run as a corporation with an independent board of directors, so no ministerial oversight. Nice work if you can get it huh? They do all driver licensing, car registration and compulsory third-party insurance, and make ~$400 million profit per year. Yeah, thanks. Cost of doing business right?

Anyway, back to the car. It used to belong to Telus, which means I have a safe in the back of it (I guess they used it for laptops?) and a Telus branded first aid kit. It also had a lot of stone chips on the paintwork, a broken cargo net, and 143k KMs (89k miles) on the clock. All of this combined to make it the cheapest Prius I've seen for sale in Vancouver in the last 3 months - $9900.

So far we've added the obligatory Apple logo sticker, repaired the cargo net (with some nifty black plastic S-hooks), touched up the paint chips with some Toyota matching paint, and bought a new tail light assembly for it off eBay.

Why a new taillight assembly you may ask? Well, I misjudged the location of a pillar while reversing into our parking stall here at the apartment block. Ewps. Mister Sheen Magic Eraser got the blue paint off the bumper, though some scratches remain, and there's a small amount of panel damage that I'll probably need to get professionally fixed, but once we get the new taillight installed, it'll look good enough ;)

Anyway, back to how we've racked up 400KMs so far. I picked Elizabeth up from a write-in, saving her well over an hour of public transport, we went to North Vancouver and had delicious curry veggie pizza, we went to Finn Slough, went to Steveston, did some exploring of Richmond (found a street with almost every major religion/belief system of the area representing - Sikhism, Buddism, Christianity, Islam, Vedic..), and did our shopping.
