Reflections in puddles – flat tyre

Low angles – using puddle reflections – keeping a clear message – dynamic composition

Most photographers would agree that reflections are the number one tool for those looking to add a little something to their pictures. It seems everyone is fascinated by them, and quite rightly too, as they provide us not only with an upside down mirror-image view of the world, their lack of clear resolution can deliver a quick and easy impressionist element to our pictures.

The obvious places to find reflections are in lakes and rivers, as well as in the window-fronted skyscrapers of the city – where we like to contrast the modern with an old church spire. We sometimes use the reflections of shop windows to show what is in and out at the same time, which is all very clever.

What we don’t do so often, mostly because we are all slightly afraid of the rain, is use the reflections in puddles to enhance our street photography. Cities and towns are filled with hopeless drainage systems and dips and holes in the pavements. These are brilliant places to find the answer to catching a completely different view of a scene that has been shot a million times, or to producing a more dynamic view of a scene that might otherwise be not so remarkable.

In this shot I wanted to capture a sense of what this slightly rundown area of Warsaw was like. I had tried quite a few different angles and compositions which all showed the street and the flats in a matter of fact sort of way that, while doing the job of communicating the content of the area, looked a little bit uninteresting. Being a rather damp place in December Poland had got me hooked on puddles, and seeing this rather exciting one, positioned perfectly next to the flat tyre of a Volkswagen Beetle, I knew my prayers had been answered.

Taking a low angle automatically creates a picture that looks different, and with the angle I was able to create a really strong horizontal convergence using the lines of the building. This makings it streak through the picture from right to left, drawing the eye right into the depths of the scene, until the eye crashes into the buildings at the end of the road. You can them come back to see the flat tyre, the eastern European car, the bare trees, the knackered kerbstones, the rusting wheel arch and all the things that I wanted to show that build a picture of the atmosphere of the place. Of course, here the puddle itself adds to the sense of dereliction, as it suggests the road is poor too – which it was.

To get such a dramatic view I used a really wide angle lens – a 10-20mm zoom at the widest setting. I didn’t want the dominant effect to be that of a wide angle, and the exaggerated sense of perspective that they can introduce, so I was careful to hold the camera as straight and level as I could. There is some ‘leaning’, but not much, and certainly not enough to draw attention. In cases like this, where the subject matter is strong in its own right, it is important to avoid photographic ‘effects’ that create a talking point in themselves. I didn’t want people to see the picture and say ‘Wow, what a wide angle’; I wanted people to notice the place and the clues that help to get a feel for what that area is like. Sometimes the power of lens effects can draw attention away from what you are trying to show, and to communicate what it is you have to say you have to be aware of that. Use photography to convey your message, not to detract from it.

The picture has a black and white look to it which I have been careful not to undo by adding saturation. I have altered the mid-tone contrast a little, by creating a kink in the central section of the Levels curve, but other than that the shot is just as the scene was.

Unless you have Live View with a flip-out screen, shooting from a low angle like this is either a guessing game or one where you lay on your face in the street. I try to wedge the camera onto the toe of my boot, as I show in this other post about low angles.

Converging Verticals – software fix

Wednesday, May 28th, 2008

Sloping Flats with converging verticals

If you have a picture you’ve already taken that has slight converging verticals the effects can often be corrected using the features contained in a number of popular software applications. The tool you should be looking for is usually called ‘Transform’, which will probably have sub sections that will be called something like ‘Perspective’ and ‘Distort’.

The idea is that the whole image is selected and then the top is stretched horizontally to counteract the inverted V shape of the building. This is a quick and effective solution to convergence in any direction, but users need to be Altering perspectiverealistic about what can be achieved before image quality suffers to badly. Obviously pixels are being stretched and made larger in one part of the image, and although the image will remain the same size detail resolution in the stretched part of the picture will suffer. If this area is mostly sky you don’t need to worry too much, but the stretch may be quite easily seen in areas of more fine detail. distorting the image

As this is the case only minor effects should be attempted, but the advantage of the method is that you will end up with a larger image than you would using the cropping method. In this example I have used a picture that is just too distorted to be able to correct easily, so you can see just where the limits are. The perspective is not only looking up, but also twisted. The correction is almost there, but the final image has a strange look to it. sloping flats with converging verticals corrected

Of course, the method relies on you having a software application that provides a ‘Transform’ tool. If yours doesn’t there is a free download application called GIMP that does – it is also a very good general purpose imaging application that offers an enormous amount of control.

Sloping Flats with converging verticalsAltering perspectiveYou can find the ‘perspective’ tool in Photoshop by clicking on ‘Edit’ and then ‘Transform’. I have overlaid the image with a grid screen to help me to get things straight. This is hidden under the ‘View’ menu, after which you need to select ‘Show’ and then ‘Grid’. You can set the preferences for the grid – such as the spacing between the lines – in the main ‘Preferences’ menu. distorting the image‘Distort’ is also under the ‘Edit>Transform’ menu and can be applied without having to finish the ‘Perspective’ adjustments. I needed ‘Distort’ Here as the camera was not square-on to the subject, so we have a twist as well as converging verticals. I’ve pulled the top of the image out and pushed the bottom left in and the bottom centre to the right. It is almost a rotational movement. Obviously the adjusted image now has chunks missing from its corners – some cropping will be in order. sloping flats with converging verticals corrected

Real-life perspective – Squeeze box man

realistic perspective street portraitsThe idea of street documentary is to show the viewer what it is like to be in the place you are shooting – and to experience the things you are experiencing. To do this I try to shoot with a perspective that delivers to the viewer a feeling of being in the place rather than simply observing it from afar.

The simplest way to begin this process is to use a lens that captures an angle similar to that which the human eyes can see. Although a 50mm lens is seen as ‘standard’ for the 135 film format and full frame sensors this is still slightly long for a realistic view. On these formats I try to use a focal length of between 30-40mm, which is the same as between 20-30mm for cameras with an APS-C type sensor, and between 15-20mm for FourThirds users.

When you use a lens like this for the type of portrait shown here you have to forget your inhibitions and move in close. This chap was more than happy for me to take his picture, but I still asked by showing the camera and expressing my intentions. This is done in a split second through facial expressions, but makes the difference between guarrenteed co-operation and comfort, and not quite knowing how the subject will react once you start shooting. Having permission also improves your chance of getting good eye contact.
The accordion player was sitting down so I crouched to get on the same level as his chest, and so I could make a major feature of the instrument. It looked almost as old as him, with just as many lines, contours and interesting features.

The day was very overcast, so I didn’t have any trouble with contrasty light and shadows blocking up his eyes or shading his face beneath his hat. It also meant that exposure was easy, and I could leave the camera’s evaluative/matrix system to do the work for me.

I shot in colour as usual, but knew this one would end up in black and white. The conversion was made using the green channel – a favourite with me for getting an aged classic look.

I cropped square as well to keep the composition tight, and because the format seems to suit the shot well.

The final image has good depth and possesses a three dimensional effect that I would not have achieved had I stood back and shot with a long lens. While long lenses allow you to keep a distance, they always show that you were a long way from the subject – which makes it difficult for the viewer to connect with the subject. Actually getting close yourself makes a massive difference, and can be the difference between getting an ordinary shot and one that has some impact.
