White balance…

without comments

…is not a camera setting to be used when shooting Caucasian people :-)

This is one of the settings that a lot of people ignore, leaving a camera on “Auto” because they don’t understand it, or are just a teeny bit frightened of it.

I have no intention of going into too much detail about it at the moment, as it’s just a way of quickly referencing a couple of tricks I use on occasion, to jazz-up an image when I’m looking for something a little different.

Truth be told, I forgot to write today’s post, and so this is being done in a panic, waaay too early in the morning, before I head out for a busy day.

Before I go on then, a quick explanation of white balance (WB):

Light has a colour temperature. You might not think so, but that’s because the human eye is a wonderful creation, far more intelligent than all the electronics that camera manufacturers can jam-in to the latest cameras. When, for instance, the human eye receives a scene that isn’t natural daylight, it compensates for any colour shift and still displays white as white so it appears that the scene is “normal”.

Cameras can’t do that. Adjusting the WB setting on the camera tells it what is really white. The “auto” setting can do it to a certain extent, but not completely.

Light varies in colour temperature from warm to cold, with different types of light in different situations giving a different temperature. Even outdoor daylight varies, depending on whether it is sunlight, cloudy, shade etc. The “value” of the light is measured in Kelvin, with daylight being very roughly 5,000 to 6,000. Camera “Auto” can usually cope from about 3,000 to 7,000, but can still give differing results between one shot and the next. That’s why about 90% of the time it’s better to set the WB manually. At least then, even if the setting is slightly wrong, all the images are going to be wrong in exactly the same way, and can be easily fixed in post-production. Manually setting the WB allows a far greater range, from about 2,000 to 10,000.

An added complication is artificial light, tungsten & fluorescent, have a tint to them. Un-corrected, a scene lit with tungsten lighting will appear to the camera to be yellowy-orange, while a scene lit with fluorescent lighting will appear green.

When using flash as a primary light source it doesn’t matter an awful amount. Portable flash (strobes) are daylight balanced, so that will eliminate much of the problem.

Oh dear, I said it wasn’t going to get techie, and it’s starting to, so I’ll head myself off at the pass and move on.

The whole (original) point before I got distracted, was that occasionally I use a little trick to change the background of an indoor scene. This little trick (and the 2nd one I’ll mention in a moment) have to be used sparingly otherwise they start to look ridiculous.

Trick 1 then is to set the camera to tungsten WB when in daylight, or a mix of artificial light and daylight, which has the effect of turning the scene blue. Of course any people in the scene turn blue as well, even if it’s not very very cold. The solution to that is to light them with flash, and fire the flash through a coloured gel. In this case it’s a CTO gel that I use. CTO = Colour Temperature Orange, orange being the opposite end of the colour spectrum to blue. Oh dear, getting techie again.

So, turn an industrial scene with dubious lighting blue, light the subjects with a gel-covered flash shooting through a white umbrella, et voila:

Used sparingly it gives another option to change a scene.

Another trick, again occasional use only, is to use a wacky lens. In this case I mean a fisheye. You can usually tell when someone gets one of these as a new toy, because every image they produce will look like someone has bent every straight line in the world. I use mine 3 or 4 times a year I’d say, no more, but sometimes it works:

That’s it, got to run…

They Shoot Horses…

without comments

…Don’t They?

Apologies if you’ve just used a search-engine and are looking for the 1969 Sydney Pollack directed film about a dance marathon, but this is nothing to do with it.

This is about me shooting horses, actually more about shooting a horse-trainer, and only shooting with a camera.

I was assigned last week by one of the “Sundays” to head out into the countryside early on a very cold morning to shoot a feature on former jockey, now trainer, Jim Culloty. Jim won many races as a jockey, including the Cheltenham Gold Cup three times in succession aboard Best Mate.

I met up with the journalist and we arrived together, so while the interview was taking place, I was off scouting locations and setting up lights.

By the time the interview was finished, I had my shot-list sorted out in my head, and lights set-up in two locations.

First up was a shot in the Yard, one-light with a mini softbox:

Then there was an archway that led from the Yard to the Gallops and I wanted something there. This was going to be quite difficult to balance the daylight coming into the arch from the Yard, with the darkness underneath the arch itself. I had set-up two lights on stands behind the conveniently located doors that hid them, both firing out towards the entrance at about 45deg. As best I could guess I had the power about right, at least that’s what the images of the back of my hand were telling me!

I had my subject lead a horse through the archway, and believe it or believe it not, I’d nailed the flash-power with the 1st image:

I made another couple in different locations, here’s one:

The one that was used was actually taken in one of the stables, no lights, just subject interacting with one of the horses. Out of about 6 frames I chose this one to transmit and it was used pretty-near full page width:

That was it. 15 minutes to set-up lights, 20 minutes shooting, 5 minutes to pack-up lights and 30 minutes & 20 miles down the road before I could feel my fingertips again.
