OCA Course: Implied Triangles


6. Mammo girls: I got fed up with relatives and friends not wanting their photograph taken so I roped in some of my colleagues from work. It was a rush job (these girls work their socks off, and, like many others, are the backbone of the NHS), so I used a digital compact with built in flash for what is essentially a snapshot. I arranged them around the mammography unit to give the triangle, but didn't account for the flare. Canon S90 on auto.


5. Little boxes 2: Ditto, but the other way up.


4. Little boxes 1: I really hate "flower arranging". My wife collects these trinkets, at least they have some intrinsic interest, but the photograph doesn't! I used an umbrella flash directly overhead to give even illumination. Canon EOS 1D Mk111, 50mm macro lens. Tripod.


3. Moorland sky: Much of the North Yorkshire Moors National Park is heather, with the odd tree thrown in. I was birding up here and this sky presented itself. The cloud formation in combination with a 17mm wide-angle lens gives a triangular perspective with the apex at the bottom. Canon EOS 40D, 17-40mm zoom.


2. Nursery: I live on the edge of the North Yorkshire Moors Forest Park, which is mostly commercial (Forestry Commission) timber production. They grow new trees from seed in these nurseries (about 11 million per year). They use mechanised techniques which result in perfectly straight rows, 5 to a strip. Perspective gives a strong triangle, apex to the top. Canon EOS 1D Mk111, 17-40mm zoom.


1. Shieldaig sunset: My wife and I were on holiday on the west coast of Scotland this summer. It was great apart from the midges, which were vicious. We had just emerged from the local hotel after having a superb meal, to be met by this superb sunset. The rigging of the yachts provide the triangles. Canon EOS 1D Mk 111, 17-40mm zoom.


Implied Triangles: It wasn't too difficult to find subject matter for this exercise, but it did prove difficult to get friends and family to pose. Strange how everyone hates their own photograph, or perhaps it's just me making a poor job of it!
This post may read from bottom to top. The last photo of the bale stack is a dilemma - is the triangle real or implied?
