Wine BS

I know I keep posting about wine snobbery, but this is about as good as it gets:

“…the 2010 Chateauneuf du Pape Les Origines. A blend of 50% Grenache, 30% Syrah and 20% Mourvedre (45- to-95-year-old vines) aged in small oak, it exhibits an opaque purple color as well as a sweet bouquet of blackberries, espresso roast, ink and graphite. While clearly a modern-styled Chateauneuf du Pape, it retains plenty of the region’s typicity and authenticity. It should drink well for 15+ years” (from a Robert Parker review)

The sweet bouquet of ink and graphite? As this blog says so well, this is Wine Bullshit at its best! (I have previously blogged about wine experts, among other topics on wine, here.)

B is for Bokeh

Bokeh (pronounced bow-kuh): Japanese for really cool out of focus backgrounds in photos!

KirstenBokeh

The background of a photo is out of focus because of the aperture chosen. A large aperture will cause most of the background to be out of focus. This is true for every lens, but some lenses give the out of focus background a special character–bokeh. No one talks about the bokeh of a 50f1.8 lens other than to say it’s crap. You will hear people talk about the bokeh of a 200f2, or one of the most famous Canon lenses, the 85f1.2LII, which was used to make the sample photo above.
Don’t expect to see much out-of-focus background when using a small sensor camera, such as a cell phone or a point-and-shoot. The physics/optics of these cameras mean that almost everything is in focus, much as in a pin-hole camera photo. (As an aside, there is much irony in the use of f64 with a large view camera of the kind used by Ansel Adams–although the format lends itself to producing massive bokeh, the members of the f64 club used incredibly small apertures in order to increase the depth of field when making landscape images.)
Bokeh is not something you have much control over, other than buying a lens with good bokeh. It’s also not something to get worried about. Most people who view your photos are not going to get all critical about the average bokeh your lens displays!

A is for Aperture

This is the first in a series of posts about photography. Let’s hope I can make it to Z!

Canon-EF-85mm-f-1.2-L-II-USM-Lens-On-1Ds-IIIAperture

Cameras capture images by allowing light to fall on the sensor (it used to be the film, but those days are over for the vast majority of photographers.) the amount of light falling on the sensor is the exposure. The exposure has two dimensions: the size of the light (aperture) and the time that it lasts (shutter speed.). Think of filing a bucket with water. The amount of water in the bucket depends on the size of the hose used to fill it, and how long the hose is turned on.
A given exposure can be achieved with a number of different combinations of aperture and shutter speed, for example 1/125 sec at f2.0 is equivalent to 1/250 sec at f1.4. A bigger “hole” for a shorter time.
Aperture is measured in f-numbers. The f-number indicates the ratio of the focal length of the lens and the diameter of the opening in the lens formed by the blades of the diaphragm. So a 50mm f2.0 lens has a maximum opening of 25mm diameter.
The photo above shows a Canon 85f1.2LII lens. The maximum aperture of this lens is 71mm (2 3/4inches!)
The maximum aperture of a lens indicates its speed. A lens with a large aperture (small f number) is a fast lens. You can use these in low light (indoors) to get photos that might otherwise need a slow shutter speed and cause blur.
The aperture of a lens is adjustable–you can “stop down” a lens to make the size of the hole smaller. Why? The aperture controls the depth of focus, or depth of field. This indicates the parts of the scene that are in focus. An image exposed with a large aperture will have a very shallow depth of field — only those things very close to the point of focus will be in focus. All other parts of the scene will be out of focus. Using a small aperture will make nearly everything appear in focus. It’s common to use a large aperture to make a portrait of a person (head shot) and have the background out of focus (see bokeh.) Landscapes are usually made with a small aperture, so that both the flower in the foreground and the mountains in the background are in focus.

As one of the two main controls of exposure, aperture is well worth understanding. Sometimes you can’t do much but open up the lens to maximum aperture (low light photos), but when there’s a choice, use the aperture as a creative control.

Notes on tipping

HeresaTip

I read this article on tipping from an ex-waitress. (I thought it was politically correct to refer to them as servers nowdays, but I guess it’s OK for an ex-waitress to call herself whatever she wants to.)

I have a simple rule on calculating the tip that I’ll share. Take the first digit (the 2 of $24.50) and double it, to get a $4 tip. This is 20% for a $20 bill, but only 15% for a $29.99 bill. So you can either still closely to it, and hope the over- and under- tips average out with repeated visits, or you can do some rounding ($29.99 is really $30, so tip $6.)

I agree with the ex-waitress that 20% has become the norm for tipping and it’s easier to calculate than the old 15% tip.

But the point she makes that I agree with most is that if you cannot afford to tip 20% or thereabouts, don’t go out to dinner! The tip is part of the expected cost of dining out, so don’t skimp on it claiming that somehow it breaks your bank. Go out less, or go to less expensive places.

Nouns are not verbs

So Merriam-Webster Online recognizes incentivize as a word. BFD. That doesn’t make it right. Why don’t we just rid ourselves of all verbs, and take all the nouns and add “ize” – or some other suitable postscript – to them to create all the verbs we need? 

There’s a long tradition of forming verbs from nouns, so why am I so upset by incentivize? Maybe it just sounds too contrived, too stupid. As an economist, incentive is part of the discipline’s jargon, so it has special meaning to me. I also believe that language is not fixed, but must change with the times. Yet, egregious verbization of nouns just irks me.

Malbec

Aside

I’ve never really liked Malbec, but I am willing to trying it occasionally, just to see if I can. I recently opened an Ascencion Malbec Reserve 2009 from Argentina. I immediately remembered why I don’t like Malbec: it’s too fruity, almost to the point of drinking an overly sweet fruit tart. You know, the kind of pie they serve at Village Inn. Without the ice cream.
