Tips for Landscape and other Photography


After all the photo workshops and photo holidays of the last summer and September I would like to sum up what was important in teaching and guiding those who attended my photo tours here in South Kerry, Ireland.
I have written about most of this before, and you may want to read those articles from earlier blogs.
There are four main categories which are more or less to be considered before setting out and taking landscape or other photos
1. Location and time of the day
2. Composition
3. Exposure
4. Technical considerations

Location and time of the day
Of course you can take photos everywhere. I often see tourists who stop at some beauty spot along the Ring of Kerry, they take out their cameras, shoot a picture or two and then travel on to the next nice view.
If you are in the area for a little longer you can find out while driving or walking what spot is really worth your time taking a planned landscape photograph. Find out which way the sun is hitting that spot at a certain time of the day. It is easiest to take pictures with the sun from behind you, everything is lit evenly and there should be no problems with the light metering, wether your camera is in automatic mode or you do it manually. All the colours come strongest and most saturated with the sun light directly shining on them. Light from the sides allows for a more pronounced contrast, it will give you dark shadows and more interesting structures.
Find out which position makes a picture even more interesting or unusual, walk around a little, try an elevated position or go down with your camera (and knees).
Pictures taken during sunrise or sunset have a special quality of light and you should really try to get up early one morning. Again, think beforehand, where do you want to go, in which direction is the sun rising and at what time. Be there a little before the actual sunrise, give yourself time to set up everything without a rush.
For sunsets, again, find out the direction and time and do not only take a photo of the red ball sinking into the sea but also before and after, literally everything has a more dramatic colour, there are deep shadows and the actual sky is well worth being taken after the sun has gone, the blues and pinks and yellows can be quite extreme and beautiful.
If you go near the sea make sure you know the tide and the swell on that day, wear sturdy shoes on cliffs etc.and just be careful.

Composition
There are some rules for good composition of a picture (a photograph or a painting/drawing too). Try to think of some when you plan your picture, although nothing is set in stone here and of course you can experiment with everything.

The first and main rule is the Rule of Thirds. Position the interesting or important subjects of your overall picture not right in the centre but along some imagined lines or even better where those lines meet. Some cameras have this grid of lines built in the screen, if not, imagine your screen divided by lines into three equal parts of each rows and columns.





       
Another "rule" is to have some actual lines leading into your picture, ideally pointing towards the main feature. This highlights the main feature and also gives the picture some depths.

Another means of making your picture more interesting is to position something in the foreground, especially with big landscapes, like a beach and sky. With position I mean you either find something which is there already (a boat, a stone or some wood landed there by a storm) and use it as it is, or you can actually put something there, well nothing too heavy, please. Try several spots of elevation too, in this case rather from lower viewpoints.
Geometrical forms of features in your chosen subject play an important role too. Triangles can point at s.th. or if any forms are repeated within the picture make use of that. Something round or spheric, especially if it is big, does not need to be in the picture in full, parts of it are enough to let your eyes and brain recognize what it is.
And there we are, parts of it, parts of something or details are what I really like and encourage students to consider taking. It is about telling a story with a picture. A detail would rather evoce questions like what...,where...and why...?
Your mind will not just register a glimps of a nice landscape, which, ok yes, is beautiful but maybe get a bit boring after looking at it three times. To demonstrate this idea, here are three pictures of roughly the same subject and my favourite one is, you guess...

A story behind a picture can also be provoced when unexpectedly or with some patience and waiting on your part a live creature moves into the frame, like a bird or cat...
And finally, take photos of your chosen subject not only in landscape but in portrait format too.

Exposure
Aperture, Shutterspeed and ISO are the three components which determine the exposure (that is the amount of light which hits the film or sensor of your camera).
If your camera is in Automatic Mode, everything gets measured and set automatically. That is fine and works in most cases. Also  a lot of cameras have scene modes for different light situations, which can help getting the right exposure.
Nevertheless I always encourage students to set their camera partially in Manual Mode.
With the ISO set as low as possible, say ISO 100, you then need to consider what kind of photograph you want:
A) a picture that is in sharp focus everywhere or


 note the "lines" going into the picture,
giving it more depth



For (A) you need to set your aperture high, that means a small number in your f-stops, e.g.f/22 if your camera goes that far, and then focus on s.th. which is about one third into the picture. (Your camera will subsequently choose the apropriate shutterspeed automatically.)

B) a picture that has your main subject in sharp focus but not the rest.
 
also note rule of thirds
       and leading lines




For (B) you want a small aperture, that means a high number in your f-stops, e.g f/2.8 or f/5.6, then focus directly on your subject which is supposed to be in sharp focus.

There is one main reason to use your camera´s shutterspeed priority settings: to capture a movement either very sharp in focus,e.g. to freeze some action in sports pictures: for that you need a very fast shutterspeed, e.g. 1/2000 sec
Or you want some blurred image, which is appropiate e.g. for moving water or the lights of moving cars at night: for that you need a long shutterspeed, usually seconds or even minutes. Your aperture will subsequently open up, that means you cannot take this kind of blurred picture with lots of light, a filter might help, but it is safest to take these pictures in the evenenings.

Something of interest in the foreground






Technical Stuff
I have always one tripod (or more) at hand, here in Kerry you need a sturdy one, even better when you can fix some weight to it, another useful gadget for SLR cameras is a remote self timer. These two help you to avoid camera shake, the use of a tripod also lets you think about what exactly you want to frame.
Take photos which really matter to you in RAW format, there is more information to work with, although you need a fairly big memory card.You also have to convert this format at some stage with some editing software because not every program can read RAW.
Always have enough batteries, memory on card and maybe some rain protection bags for all your gear.
Certain filters cann be applied to some lenses, they are helpful when the sky is too bright or they bring out clouds in a dull, or overcast sky.

If this sounds all a bit overwhelming, I can assure you I am not a dry, lecturing type of teacher, all  the tuitions where practical and hands on and tailored on the spot to arising topics, needs or problems.

Heritage and Photography Workshop on Church Island








After a very rainy night I
opened my eyes in the
morning to see the
sun shining,what a day.
Greatest photography
weather,blue sky,
clouds that move and
a slight breeze,just right.
Our boat man,
Neil O´Shea, brought
us safely to the island
where the tripods
and the cameras had
a rest, while Paddy Bushe
gave an
interesting and detailed
talk about the history
and heritage of
Church Island,
or Oileàn an Teampaill,
the Island of the Nobles.

Most interesting are the
tomb stones,leachta and
of course the two main
buildings,St.Finians Church
and St.Finians Cell.
I liked the small
walls and steps
that are there after
all those hundreds of
years exposed to
the weather.



Here are a few tips
how to take images of details,
stone crosses and
architecture.

Set image quality to high or fine, or take the images as raw and jpg-files, so you will get more details in your images, particularly if you want big prints later on.
Also set ISO to 80 -100, for best results.

Use a tripod,it slows your movement down and makes you think about the image you are going to create.
Some of the tripods were a bit light for outdoor photography, but can always steady them with some kind of weight. Some tripods have a hook at the bottom of the center column where you can hang e.g.your camera bag as a weight or some fishing net filled with stones...

Follow the light. Look where the sun is and take pictures in the opposite direction. Most cameras on automatic settings get confused if you shoot in the direction of the sun, the sky will be pale or too dark,you won´t get this if you point the other way. Just make sure your own shadow is not in the picture.
You will get nice detailed images of inscriptions and carvings if you get the sun at an angle of 45 degrees or less.

Take images of details, a lot.
To tell the story about the things you have seen, take as many photos of details as possible. Use portrait mode for details and get close to your subject or zoom in. For whole buildings landscape mode with a wide angle setting is better especially inside rooms.

Experiment with aperture!
If you like your images a bit different reduce your aperture from for instance f/13 down to f/6.3 or f/5.6
this will give you a nice blurred background and helps you focusing on your subject.
On the other side you can get some nice shots when you stay in wide angle mode and take pictures with apertures 16 or 22. Everything will be sharp and crisp.

If you are having a slr camera, try the mirror lock and a remote control. You will be surprised how much less camera shake you get. This is in particular great for long exposures, night shots or macro photography.
Better again if you put your camera on to a tripod.

Carry a second battery ,enough memory cards and your camera manual with you. A plastic bag weighs nothing and keeps your camera bag dry in the seldom event of some soft Irish rain.




Thank you all for taking part in the workshop, especially Peggy O´Shea who sent in these three pictures.

Understanding Exposure



One easy way to demonstrate how exposure works
is this Exposure Triangle.
Exposure is the amount of light which comes in contact with your camera´s film or sensor.


You need to get three things right to achieve optimum exposure for your photograph:

Aperture - which controls the size of the lens opening for light.
Shutter speed - which controls the time light is allowed to come in.
ISO - which controls the sensor`s or film`s sensitivity to light.



A change of one element will have an impact on the others.
A big aperture only needs a short shutter speed and vice versa.
Dark light conditions call for a higher ISO, but your picture will look grainier than with a small ISO of e.g.100.

Most cameras offer a variety of exposure modes – from fully automatic to semi automatic and scene mode to a full manual mode.

Automatic mode
The camera selects all settings depending on the type of lighting and brightness of a scene. It focuses automatically and fires a flash when light is insufficient.

Semi- automatic modes
Aperture priority mode(A or AV)-you select the aperture and the camera automatically sets the other two.

When would you want to do that? To get the depth of field right for your purpose!
If you want everything in sharp focus choose a small aperture
(big number e.g. f/22) and let the camera choose the appropriate shutter speed.

If you want only part of your subject in sharp focus and blur the background
choose a big aperture (small number, e.g. f/2.8) and let the camera do the rest.

Shutter priority mode(T or Tv)- you select the shutter speed and the camera sets the rest.

When would you do that? To control moving subjects!

To get your moving subject to freeze, that is, everything is sharp in focus, choose a fast shutter speed of e.g.1/2000 sec and again, let the camera do the rest.
To illustrate how fast something is moving - a blur around your subject can indicate speed, choose a slow time of about 1/125 sec and your camera will set a smaller aperture.

Scene modes
A variety of pre programmed modes for portraits, landscapes, artificial light in doors, some outdoor lighting situations etc…

Manual mode(M)
You set shutter speed, aperture and ISO and the light meter will tell you whether or not the exposure is right.

When you take landscape shots you usually have time to think a little before you press the shutter release so try and take more pictures in manual mode. I prefer to do this and I usually think about aperture first, set ISO at the least possible 80 or 100 and the see what the light meter tells me about shutter speed.
For longer shutter speeds you need a fairly steady hand or better still a tripod.
