Troubleshooting common mistakes and problems in plant photography

One of the first things I usually do after starting up my computer in the morning, is checking which new observations there are on the site of iSpot Southern Africa. If you are interested in the flora and fauna of this part of the world, it is well worth having a look at this site (  http://www.ispot.org.za/ ). The quality of the pictures people upload to it is quite diverse, sometimes to a point where it is difficult to even recognize the subject.  This is not to say that this site is worse than many others in this respect, it is just that I am so often confronted with the results here.
Judging from the way most people photograph, I strongly believe they do not spend enough time on taking their pictures. Maybe I’m just getting a miserable old git, but I think that it is a waste of time to take pictures when the results become a kind of hit-and-miss thing.  Believe me, I’ve been there, done that. Nowadays I’d rather spend 5 minutes on taking one or two worthwhile pictures than 1 minute on taking a whole lot of useless ones. Your mileage may vary of course and I would be interested to hear from you if you have  another opinion.
For a bit of more specific advice I refer you to the following text, which is a slightly adapted paragraph from my book on plant photography.

Too many elements in the picture, so that the viewer has to guess what you want to convey.
This cannot usually be remedied afterwards; in some cases cropping the picture help.
For future shots try the following :
1 Get closer.
2 Change angle of view to get different background.
3 Use  greater focal length.
Subject not standing out
If there is too little contrast (in colour and/or light) between subject and background, the problem can sometimes be solved in post-production.
If the background is too much in focus there is no way you can improve this picture.
In the future pay extra attention to the background and squint your eyes at the scene to judge the light conditions, before you press the shutter.
Distracting elements in background
This probably means that the Depth of Field (see definition below) is too much.
In certain cases post- production may solve (part of) the problem.
In the future use a shallower DoF (check the scene with the DoF preview button) and/or block distracting elements (esp. bright patches).
Spend more time studying what is in the picture frame.
Depth of field (DoF)
This is the distance over which objects remain acceptably sharp in front of and behind the point on which the lens is focused.
In simple terms: DoF is the part of the scene that appears acceptably sharp in a photograph.
DoF is determined by 3 factors: the focal length, the aperture and the distance between camera and subject.
It decreases as the focal length of the lens becomes greater, the aperture is made bigger and the distance between camera and subject is diminished.
Subject too small in picture space
The picture is taken from too far away or with too short a focal length.
Cropping the picture may offer a solution.
For future shots move in closer or use a longer lens.
Wrong DoF
This means that there is either too much or too little of it, or that it is in the wrong place.
None of these issues can be remedied in an existing picture.
For future shots you should pay more attention to using the right aperture and/or spend more time on focussing properly.
Wrong background (too light or too dark; wrong colour; too cluttered)
Like with so many other problems, the scene was not screened well enough.
Only the first two issues may be improved in post-production (if you are lucky).
Next time spend more time studying the subject before pressing the shutter.
Flare
Light hitting the lens or a filter in front of it is the cause here.
There is no remedy for an existing picture.
For future shots use a lens cap or something else (such as a hand or a hat) to shade the lens.
In some cases flare may add a certain quality to the picture, so instead of avoiding it you may also try to put it to good use.
Main subject too dark or too bright
This occurs when the contrast in brightness between subject and background is too big.
It may be corrected (partly) in post- production.
To avoid this problem next time, use a smaller aperture for a light subject against a dark background and vice versa.
Picture blurred
Unfortunately there is no remedy for this issue.
When the whole picture looks fuzzy, this is caused by camera movement. Avoid this next time by using a tripod and possibly also a cable release or a self-timer delay.
When only part of the shot is blurred, the probable cause is wind. This can be prevented by using a shorter shutter speed.
Contrast in picture too high
When the difference between light and dark elements is too big for the sensor to cope with, this will be the result.
It may be corrected (partly) in post- production.
With smallish subjects, use of a diffuser and/or reflector may avoid this problem. Flash might also help.
Parts of subject damaged, discoloured etc
This happens amazingly often when not enough attention is paid to the subject matter.
In some cases the offending parts may be cropped out, but it is much better to look for unblemished subject matter next time. Continue reading Troubleshooting common mistakes and problems in plant photography

Haworthia decipiens var. decipiens

Today’s post is the first in what is intended to become a daily posting of one or more interesting and beautiful pictures (mainly) of succulent plants. The text will be kept to a minimum, so as not to distract from the images. These post will be an addition to, not a replacement for, the usual ones.
You may also notice that I have added a photo gallery to the blog. Enjoy!
We kick off with two pictures that are identical, except for the fact that one was taken with a diffusor. That one seemingly little difference produces quite a different result. One can not really say that one picture is better than the other, but they give different information and also evoke a different feeling. When the light is harsh like in this case, it is worth taking a couple of pictures with and without a diffusor or reflector.

Some Poellnitzia pictures

It keeps amazing me how sometimes you decide to do something and you end up with a totally different thing from what you had in mind. This post is a case in point.
I thought it would be a good idea to write a post on a certain aspect of plant photography that is often neglected (paralleling the subject) and went out into the garden to take some pictures to illustrate the principle. As it happened, there was a nice specimen of Poellnitzia in flower that seemed to fit the bill. Because the inflorescence in these plants is rather long and thin, even the gentle breeze that was blowing made it almost impossible to make a sharp picture. Quite a while ago I bought a gadget especially for occasions like this, where you have to stabilise something that is moving in the wind. It is called a Plamp (plant clamp) and  has a couple of other uses as well.  Although I rarely (have to) use it, it may make the difference between a good picture and a bad one (or none at all).  Have a look at http://www.tripodhead.com/products/plamp-main.cfm for more info.
Even after the inflorescence as such had now been stabilised, the individual flowers were slightly moving in the wind. This defeated the object of showing the differences in depth of field as a result of different camera angles. After the rigmarole of setting up camera, tripod and Plamp, combined with the fact that a flowering plant of this species is not a common sight, I was rather reluctant to just pack up and leave. So I decided to have another look at what was there. As usual, I started with a couple of what my friend Neil Curry, a retired filmmaker, uses to call establishing shots, showing the subject in its environment.

_DSC8538-2res
The background was nice and dark but because I did not compensate for its darkness this is how the picture turned out.

_DSC8538-a-2res
This is what it looked like after taking a second picture with one stop underexposure and some fiddling in post production. You will notice that I also removed some of the nasty light blotches in the background.

_DSC8550res
After this, I went somewhat closer up and photographed only the middle part of the inflorescence.

_DSC8547-2res
Because the tips of the flowers have a unique shape I decided to make a picture of those at natural size. The flowers are so special in fact, that a whole genus (Poellnitzia) was established to accommodate just one species (rubriflora).

_DSC8552res
The plant itself is similar in shape to species in related genera (Aloe, Astroloba, Haworthia) but the colour is rather special.

 

Machairophyllums flowering after fire

In an earlier post I referred to a fire that raged on the nearby Rooiberg about a year ago.
Approximately half a year after the fire we discovered a great number of flowering Machairophyllums in the burnt areas.
Although there are several populations on the Rooiberg, we had never found a flowering specimen before and we wondered why that was. Had we never been there in the right time of the year and of the day (the flowers open after dark) or did the plants, like so many others occurring in fynbos, need a fire to trigger flowering?
Last Sunday we decided to visit the mountain again and see if we could find out if the Machairophyllums in the not burned areas had flowered so profusely last year as well. This is easy to establish because the fruits stay on the plants for a long time. We saw a couple of hundred plants in perfect condition, but only very few with  (max. 2-3) fruits.  If you look at the accompanying pictures (taken last October), you will see how profusely the plants flower after a fire.
All in all It seems safe to say that  this species of Machairophyllum -and probably the others too- may not be totally dependent on fire to trigger flowering, but that it certainly makes an enormous difference.
When I say “this species of Machairophyllum “ you probably wonder exactly what species we are talking about here. Comparing all the information from literature, I come to the conclusion it is most probably M. albidum.  Apparently other people too have a problem deciding which is which in this genus: The Illustrated Handbook of Succulent Plants recognises 7 species but also says “The genus is under study and four or five species may only be distinguishable”.

Looking and seeing

“Our looking is perfected every day-but we see less and less. Never has it been more urgent to speak of SEEING. Onlookers we are, spectators…”subjects” we are, that look at “objects”. Quickly we stick labels on all that is, labels that stick once – and for all. By these labels we recognize everything but no longer SEE anything. We know the labels on all the bottles, but never taste the wine. “
Frederick Franck, The Zen of Seeing

“You learn to see by practice. It’s just like playing tennis, you get better the more you play. The more you look around at things, the more you see. The more you photograph, the more you realize what can be photographed and what can’t be photographed. You just have to keep doing it.”
Eliot Porter

When we want to take our photography to a higher level, we must learn to observe better. It is not about visiting exciting places and having wonderful subjects in front of us.
Even in the most ordinary places you may find something of interest. It has little to do with the things you see and everything with the way you see them. The more carefully you observe things, the better your pictures will become. You can only really learn how to do this when you are able to relax. As long as your mind is filled with worries and concerns, you are occupied with yourself and not with the things you want to see. Therefore, you must try to clear your mind. Unfortunately, this is easier said than done. A good start would be reading Jon Kabat-Zinn’s inspiring book  “Wherever You Go, There You Are”.
Once you know how to relax, you can go on to the second step: paying attention to something or somebody.
As Freeman Patterson says in one of his books: “The trick is to learn how to switch yourself off, so you can switch your subject matter on. You have to “let go”.”
In other words, you must develop an attitude of “relaxed attentiveness”. This sounds like a contradiction in terms, and certainly it is not is easily accomplished. Nevertheless, it is well worth trying to get there.
Mindfulness is another word to refer to this state, in which we are not going anywhere or looking for anything specifically, but are one with what is surrounding us. Once we are able to “switch ourselves off”, we allow the picture to find us, instead of us trying to find the picture.
Most of us seem to suffer from sensory overload nowadays and we cannot pay constant attention to all the stimuli that we are subjected to. It is however possible to tune in to specific ones if they are of sufficient interest to us.

I remember an afternoon during one of the first photo workshops that I attended in South Africa. We stopped somewhere in the mountains near Kamieskroon and within minutes everybody was happily shooting away at rocks, trees, flowers, insects and what not. Everybody except me, that is. I was still busy trying to wind down, to relax, to “get in the mood”. Suddenly I became aware of the enormous variety of subjects and of the many ways people were responding to them: some were on all fours , one or two were lying on their backs looking up into a tree, others were sitting on rocks or in trees looking down, etc, etc. So, if I was the only one not seeing anything worth photographing, it obviously had to do with me and not with a lack of suitable subject matter. As soon as I realised this, the “what should I photograph” spell was broken and I started taking pictures just as happily as all the others.

Often one is so focused on the point of interest in the picture frame, that all the rest is not seen consciously. Apparently, the brain filters out much of the “noise” around us.
Richard Zakia (Perception and Imaging, 1997) describes this as: “We only see a small fraction of what we look at, and more often than not we “level” what we look at rather than “sharpen” it.”
One of the strongest barriers to seeing is categorizing and labeling:
– “why should I take a picture of that, it is only a nasty weed”;
– “no good photographing this flower, it’s not fully open yet”;
– “I don’t know this plant’s name, so there’s no use spending time on it”, etc.
It is only when we can leave this stage behind us that we will really see and realise that even simple, daily things can be very interesting.
As Robert Adams (Beauty in Photography, 1996) puts it: “Bell peppers would seem to be about as limited as any subject matter could be, but in fact how unlimited they are when photographed by Weston.”
Another attitude problem is caused by the “been there, done that” syndrome: you look at something and think: “Well, yes, I have seen this many times before and I do have pictures of it, so why waste time looking at it again”. (Never mind that it is not exactly the same thing; it is a different time of day, another season etc.). It may even be very useful to return to the same subject several times, because this will force you to look at it in new and unusual ways.
We need to have something like the receptiveness of a child looking at a thing for the first time. We can only hope to regain this wonderful innocent vision by breaking away from rigid, conventional ways of seeing and thinking.
A good way to improve your seeing is to look regularly at possible subjects through a small opening cut in a piece of cardboard. The opening should be about 10 x 15 cm (with the same aspect ratio as your viewfinder.
Because drawing  sharpens the visual senses,  one of the best ways to learn how to see better would be to attend a couple of art classes or study a book on learning how to draw. This may sound strange at first, but when you give it a try, you will find out that it really works. You will not only start looking at things in a different way, but also see things you never saw before.

The above is a somewhat modified chapter of my ebook on plant photography. The rest of this post is devoted to a recent example of looking and seeing “out of the box”.

Last Wednesday our small local photo group had its monthly meeting.  All the members had to show a couple of pictures of kitchen implements. Hardly an interesting subject one may think, but its very mundaneness had forced us to look at things in a different way.
Some of the results were quite surprising. The following pictures were part of my contribution : there is no direct relationship with plant photography, but the pictures give you a good idea what can happen if you let go of pre-conceived notions of what things should look like.

Two interesting Euphorbias from the southern Great Karoo. Part 2: The start of a hybrid swarm?

Because this area harbours a variety of interesting succulents, we had high expectations of what we might come across. Nevertheless, the rest of the trip was rather boring. That is, till the moment George pointed out a big clump of what we both thought was Euphorbia stellispina, in a field next to the road. Finding that species in itself, would have been nice enough, but when we walked up to the plant, we discovered that it was much more special: about all the plant’s features were perfectly in between those of E. stellispina and E. heptagona.  The result was spectacular.

Two pictures of the purported hybrid

When we searched the immediate surroundings, we found plants of both these species, which strengthened the idea that our plant was a hybrid between the two.

To make the find even more exciting, after some looking around we came across another hybrid between the same parents.

More interesting than beautiful

Here the results of the mix are totally different and far less appealing. On the other hand it is exciting to witness what may be the beginning of a hybrid swarm and it would be interesting to follow the population’s behaviour over some time.

Two interesting Euphorbias from the southern Great Karoo, part 1: E. braunsii

Last month my  friend George Hatting and I decided to spend a Sunday looking for plants in the Prince Albert area. We had both been there before and discovered some interesting plants.  After a nice drive over the spectacular Swartberg Pass, we arrived in Prince Albert and took a gravel road road from there heading east. Shortly after leaving town, we stopped at a place that looked promising and found a couple of beautiful small Euphorbia’s.  They clearly were plants of E. braunsii, which is well known from the area.

euphbrau2012-10-03#024_lznres
This is how E. braunsii usually looks in the wild (well, normally without fruits, of course). Photo taken near Prince Albert on 10 Oct. 2012.

The peculiar thing was that they were in leaf, something I had never seen before and which is apparently a rare phenomenon. Digging into my literature I found no mention of the leaves, let alone a description or picture of them. The most likely explanation for this is that the leaves are short lived, as in the related (or maybe even identical) species E. rudis from Namaqualand and Namibia. Whatever is the case, I was quite chuffed to be there right on time to photograph the leaves, especially as they add an extra dimension to an already charming plant.
