19th March 2015 – On the feast of St Patrick or “These are small, those are far away”

The Escape Committee

 

Slightly late for St Patrick, last Thursday had a distinctly emerald tinge to it, as the club celebrated the Apostle of Ireland with a photographic evening. We were joined by local model Kelly Wolf Rogers and various club members were dressed in (at least) forty shades of green. There were balloons too. And cake. Thanks to everyone involved in getting this event together, it was a good humoured and very enjoyable one. We don’t set so much store against Saints days in the modern era (not least because, strictly speaking, it is a denominational affair) but they were and are  a way of setting out the seasons.  St Valentine’s day is where the bleakness of winter starts to be broken by wild primroses, crocuses and aubretia (those small, usually purple, flowers that grow in clumps I am reasonably informed, however, to me Hell is a Garden Centre so I would probably have accepted that it was a form of fungal infection just as readily). Saint David’s day is a bit early for our idea of spring but there is plenty going on. Paddy’s day and you may start to see the first of the bluebells in the far south west, but by St George’s day spring is resolutely marching north across the country at a steady walking pace. Warmer, if not entirely dry, weather entices the less hardy outdoors.

 

We are not short, in other words, of photo opportunities provided by nature, from the very small to the grand vista.  Let’s start with the very small. I am using the term close up rather than macro in deference to the technical definitions of such that hold macro to start at an image reproduction ratio of 1:1, that is life size. A third term you often come across is micro photography and they are pretty much interchangeable in any camera company marketing department. A few, if obvious, facts bare illuminating as our plot unfolds. Every lens has a minimum focusing distance. The longer the lens the, generally, further away from the camera that will be. Short focal length lenses focus closer. Depth of field is shallower/deeper the more telephoto/wide angle you go. Smaller than about f16, apertures start to soften out the image because of light diffraction.

 

So, speaking in close up terms, there are ways of getting more out of your lenses than the manufacturer designed for and each have their pros and cons. You can also ally these with certain software tricks, such as focus stacking, so as to cheat more out of your equipment. Certainly this is an instance of where a tripod is an absolute necessity (at least until you can slowly zoom in video on 4k – 8mb per frame – , or Sony’s rumoured 8k DSLT – 33mb per frame) , but that doesn’t mean that you have to bring the outdoors indoors to achieve it. Neither do you have to go to extremes, these things can be found around the house, e.g. a pot plant, fruit, etc. but also “in situ” as it were. Why, essentially, do we need to do this when we are shooting close up? After all we usually only have space for one thing to be in focus, indeed, often to fit in the frame. The first problem that we usually have to contend with is depth of field. The D.o.F. on a 50mm lens set at f8, focusing on an object  25cms (10 inches) away is less than a centimetre (about 4/10ths of an inch in imperial) on a 1.5x crop sensor. It would be less on a full frame sensor. Autofocus may not cope, so be prepared to go to manual.

 

Nature, it has been observed, is wild and inclusive, whereas art is about choice and exclusion. In the discussion, very broad as it was, on the last blog, on the section about wide angle lenses, it was stated that they are commonly associated with getting all the view in shot, whereas it is an invitation to get in close. To marry these two observations we need to think in terms of why what we have in the viewfinder is there and also to investigate other angles too. Don’t forget to press the shutter though. So what has this to do with close up photography? More than it would at first appear. In both instances a small detail in a larger context is the situation for our image’s story. By deciding we want a close up of that insect, that petal, those leaves etc we are making very definite decisions about excluding other detail from this story. Coming back to the detail idea, what is obvious in close up photography, applies, just not necessarily as obviously, to landscapes, portraits and so on. We have been told by more than one judge at the competition rounds (next round at the next meeting, f.y.i.) that there is room in any frame for a single story. When we are using wide angle lenses to capture an image the edges of the view become more important than is the case with telephoto’s.

 

The reason, of course is that there are more chances to cover more objects and those objects could   be distracting to the eye. This is also something you can get in the close up, extraneous detail you overlook because you get target fixated. That target in close up photography is the in focus area. We end up concentrating so hard on that we miss what is glaringly obvious in post production. That detail we miss will almost certainly be a little off centre, (or centre of attention). The same happens with wide angle lenses, the wider the angle the more of a problem. Attention can be distracted quite unintentionally so you need to be aware more of what is on the outside of the frame.

 

Lighting for close up outdoors is also less of an issue and a different set of problems. Whereas the “ideal” light for landscape falls within the Golden Hour, and some landscapers won’t photograph in anything else, a lot of opportunities exist throughout the day – and you don’t always have the opportunity of going back at a more fortuitous hour (and can’t control the weather if you do). Judicious use of reflectors or auxiliary lights, flashes etc (though not the one on the camera as it will fall within the shadow of the lens and will unlikely be reducible to useful strength if it doesn’t) can certainly help in ways that are inconceivable for the bigger picture. If you want to wait for the golden hour, the details in the landscape, even down to the very small ones still offer opportunities.
