A single bold colour – red umbrella on a snowy morning

Using bold colours · making a colour stand out · low light photography · having patience · shooting raw

Red umbrella in the snow. The Bank, London. By Damien Demolder

I’m not a great fan of black and white images that use a spot of colour. It seems a little forced to me, and the effort that goes into this sort of picture post capture is rarely rewarded with an attractive image. Well, that’s just my taste, anyway. I do like images that use limited colour, so long as the setting is natural or realistic looking. And, in fact, I actively go looking for this sort of thing – not just to show a black and white scene with a burst of colour, but rather to show how some colours can stand out against others.

I took this picture outside the Bank of England, in a square I cross everyday on my way to work. The place has a great atmosphere about it and it’s a favourite place of mine. I like to shoot the commuters as they emerge from the underground station, as they come out well lit into gloom of the morning. On this morning the wet snow added to the gloom, but it also created the luck that had this chap appear with his rather buckled bright red umbrella. While usually this is a monochromatic type of scene, the bold brolly really broke the formal grey and upright structures with it burst of jollity.

As always when I’m shooting at night, or in dawn or dusk situations, I had the camera set to raw+jpeg so I can choose which light source to balance for afterwards. In this case I took a custom white balance sample from the white tiles of the underground tunnel, the light of which matched that shining on the man and his brolly. Doing this made him look normal, while the cold of the sky could be brought out with its blue.

This wasn’t the first picture I took at this spot that day – I’d probably shot four or five other people as they emerged from the tunnel, and while they looked pretty good I reckoned that by hanging on I could improve my chances of getting something extra. It paid off – and it usually does. I spot a scene with potential and frame it up – then just wait for the right person to come along and walk right into the picture. It takes a bit of patience, but that’s the whole point. You need to be able to recognise when you haven’t quite got the best shot that could be had, and that by waiting a little longer you could improve it.

As with the other pictures I took before hand, without the brolly this is a picture of a man coming out of a tunnel. With the brolly it becomes something more exciting. And that’s what you get when you mix luck with patience.

Using exposure lock – Beach Boys at Sunset

Friday, August 15th, 2008

Think about your metering system • Exposure lock • Finding a mid tone • Daylight white balance

Boat Boys refueling their speed boat on the beach at sunset, Skiathos, Greece. The correct exposure. Cameras are machines, and although they do feature a certain amount of artificial intelligence, ultimately they can only do as they are told. Knowing how your camera is likely to react in any given situation is the key to understanding when it is destined to get things wrong and that it is time for you to take control.
In a situation like this, where we are shooting into the light, and the sun is reflecting off the sea, the camera’s metering system will assume it is looking at a very bright subject – which it is. The camera will try to render the sea and sky so that we can see the detail – so it will aim to create a mid-tone of them. Only you know that it isn’t the sea and sky that you want to see the detail of, but it’s the people and the boat that are the subjects.

Finding a mid tone
To produce a final picture that looks the way we want it to we have to take control of the exposure and so over-ride the metering system. Instead of letting the camera measure the light reflecting off the sea, which is what it would do if left to its own devices, we have to direct it to an area we think is important. To get the right exposure for this scene I took a reading from the sand on the beach by my feet and then locked this reading into the camera, using the exposure lock button. I used the sand to take a reading from as it offered a good compromise between getting an exposure that would show the details of the faces and keeping the idea of silhouettes against the sky.

If you are going to take lots of pictures using the same exposure it can be simpler to transfer the exposure settings into manual exposure mode so there is no danger of the lock coming ‘unlocked’.
This reading has preserved enough detail in the boat and the people to show what they are doing and the expressions on their faces, while still holding on to that backlit sunset atmosphere.

Had I left the exposure up to the camera the picture would have turned out something like this. Although still an effective image, I prefer the version that shows more detail in the subjects.

White balance
Another important aspect of the shot is the colours of the sea and the sky. I kept the white balance set to ‘daylight’ to make the most of the natural warmth of the sun at that time of day. Had I left the camera in auto white balance (AWB) mode the camera would have tried to compensate for the warm, taking it out, which would have defeated the object of shooting at that time of day.

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
