New directions
...
Inspired by Galleria d'Arte de Kimiyo, this blog goes in a new direction.
o2jottings becomes the column addressing such questions as, "Why take photographs?" ... "What is this photo trying to tell us?" ..."Is the photograph succeeding in informing us, or making us feel something?"
wh5 takes over as the blog dedicated to conversation analysis.
Today, out on Mount Takao, after I'd taken a picture of sakura in full bloom with only the sakura in focus, one of the party asked me to take a picture of a branch of sakura but to include maple leaves hanging behind it.
Picture 1: taken at f4, sakura in clear focus, with a maple leaf bokeh behind it.
Picture2: taken at f22, both sakura and maple in clear focus because of deep depth of field (DOF).
Picture 1 separates the sakura from the maple leaf background and draws our attention to the sakura.
Picture 2 has an abundant green background but loses the sakura.

I am delighted with the migration of the blog into the field of photos but I just hope it won't get too technical. I'm sure many of your loyal readers would appreciate good practical advice from the layman's perspective. For example, the other day I nearly got killed trying to take a picture of a really big building because I had to stand in the middle of a busy road to fit it in. Any advice to protect my life that does not involve expensive lenses?
Pleased to hear you are back safely from the middle of the road, Pencillist.
Taking pictures of buildings, up close, involves getting two things straight. First, you have to fit the building into the picture. Second, it’s nice if the walls of the building are straight and do not curve in towards the centre of the picture.
This involves using a wide-angle lens. Numbers indicate this. The number of mms refers to the focal length, that is, the distance from the front of the lens to the camera's sensor.
For example, a lens between 16mm or 24mm is considered wide angle. A nice lens to use on a Canon is the 17-40mm wide-angle zoom lens.
A 50 mm lens is for general shots, and a telephoto lens may be 135mm, or 200mm or more. These lenses are only used for buildings that are far away.
Bear in mind, however, that a wide-angle lens used on a consumer grade model like the Canon 450D will not produce as wide angle pictures as it will on a “full-frame” or prosumer or professional camera like the Canon 5D.
Sorry Pencilist, for both misspelling your name and properly answering your question.
Taking pictures of buildings not involving expensive lenses? Or cameras, for that matter.
Well, you could try a dedicated wide-angle digicamera, like the Rich CX1 a new digital camera with a 7.1x optical wide-angle zoom lens (28-200 mm in 35 mm film equivalent focal length). Claims to be able to take 4 frames a second, too.
But from my experience with digicams, they are painfully slow to work with, you lose more shots than you catch, so if you are serious about taking decent pix, you probably need to look at a camera with interchangeable lenses.
