More White Balance

To understand why you might need to adjust the white balance in your camera, you first need to understand color temperature.

Adjusting the white balance basically means making sure that a part of the picture that is supposed to be a neutral color does actually contain equal amounts of red, green and blue. We call it white balance but it works equally well with light gray parts of the scene, however generally speaking the lighter the better. If the gray parts of the picture are indeed rendered gray then it follows that all the other colors in the scene will be rendered in a natural looking way.

On the right you can see the effect of right and wrong white balance in a composition with delicate colors. The more pastel the colors in the scene the more important it is to get the white balance correct.

On most modern cameras we have an AWB (automatic white balance) setting, various fixedcolor temperature settings such as ‘daylight’, ‘tungsten’ and ‘flash’ and, on the better cameras, and a custom setting. Read the rest of this entry »

Details

   

At an event in addition to shooting regular shots, try to pay attention to the details instead of the whole thing. A ring that slides over a finger is far more penetrating than two people that are doing ‘something’ with each other’s hands. A pen that floats over a sheet of paper says more than someone signing their signature. A knife disappearing into the cake is more artistic than the obligatory photograph of the couple cutting it. Be

creative and zoom in on the details that symbolise a situation or act. Also have a

look at how the location has been decorated. Photograph the streamers, a tray of

champagne glasses or a festively laid table just before the dinner commences.Again, the same applies that a single artistically folded napkin can say more than twenty covers in a row.

 

Look at the detail capturedI used a macro mode on this one.

Composition

One of the most effective ways to make your digital images more interesting to the eye is to change the angle that you’re shooting from.
Let me use an illustration of a couple of pictures I took of a big pineapple (don’t ask – it’s an Australian thing). Read the rest of this entry »

White Balance

White Balance is an aspect of photography that many digital camera owners don’t understand or use – but it’s something well worth learning about as it can have a real impact upon the shots you take. Read the rest of this entry »

Bokeh

Bokeh is a photographic term derived from Japanese.  It means out of focus background using a shallow depth of field but in a way that is pleasing to the eyes.  The word Bokeh is pronounced same as the word “bouquet” as in flower.  Do not mix up Bokeh and Brokeh.  Bokeh is a beautiful background out of focus blur.  Brokeh is zero in the wallet.  Bokeh is what you get with an expensive, prime lens and Brokeh is what you get when you buy that expensive lens!

Close up photography

The other day I was asked to take some pictures of snails which got me thinking about the perils of close-up photography in general.

The first problem we need to look at is, how close the lens will focus. Lenses have a minimum focus distance which varies considerably from lens to lens, some longer zoom lenses have a ‘macro’ setting and will focus quite close but most lenses will not focus close enough to take the picture on the right.

ISO Speed

As we have already learnt shutter speed and aperture work together to control how much light enters the camera when taking a picture.  The amount of light required is dependent on the cameras recording – in a film camera the negative, in a digital camera the image sensor.

Depth of Field

Any experienced photographer will tell you that Depth of Field- otherwise known as DOF- is a crucial factor in photography.  Depth of field is how much of a picture is in sharp focus.   The larger the DOF, the bigger the zone of sharpness.

How do you change the DOF? Well one way is to change the aperture.  A low aperture, such as F3.4,  will have a shallow depth of field, resulting in the background being blurry and the main subject being very sharp.  This is a good example of a shallow DOF.

A aperture of F11 will have a greater zone of sharpness.

Zooming in to a subject also results in a shallow DOF, whilst just coming close to a subject will give a large DOF.

Blur 2

Now for the good aspect of a blur.

A picture, if the background is busy, resulting in the main subject being overlooked, is BAD. When the background is blurred the main subject screams “look at me!!!”. This picture, I think is a good example.

Blurring  the background of this picture made it look very good!!!

I will probably soon write an article on blurring the background of your picture.

Buying a Digital Camera

I saw this very interesting article on www.geofflawrence.com and I thought I would share it with you. It is some questions that you have to ask yourself bebore buying a camera.

With so many camera models to choose from, at a bewildering range of prices, where do you start? Well, the way I choose any new toy these days is to start at the end. What do you want it to do? Err . . . take pictures. Yes but what kind of pictures and what are you going to do with them? The other burning question is how much are you prepared to learn? And, of course, how much are you prepared to pay?

As you are reading this and have actually made it to paragraph two, I think we can assume that you are prepared to learn at least a little. So what do you want to do? Do you want something that you can keep in your pocket at all times so you can snap the kids? Do you want a camera that will allow you to take pictures in any lighting conditions from any distance (with the right gadget screwed on the front of course)? Is this going to be a hobby or just some quick snaps?

I haven’t seen any cameras on sale in recent years that do not have a fully automatic ‘point and shoot’ mode, most will automatically switch on the flash for you when it is needed so you may wonder why we need all the other manual and semi automatic modes and an instruction book to make your head spin.

The answer is that, although the camera can produce good exposures most of the time, there are times when, to get the results we want, we have to apply a little know-how and select more appropriate settings than the camera would automatically choose.

Before choosing a camera with lots of knobs and dials it is a good idea to consider whether you are ever going to bother to learn what they are all for. I’ve been around cameras for many years now, and I’m still learning what all the settings on my latest camera actually do. I never bother to learn how to do something until I need to. So there are certain obscure settings that I have yet to find a use for. Of course it would be nice if we could choose just the buttons we need and have each camera custom made for us but in the real world all we can do is choose the level of control based on how much we think we might want to get involved. Generally speaking an SLR will have more knobs, dials and menus than a compact camera which will give you more control over your pictures but will have a much steeper learning curve.

All the cameras on the market can be categorised into a few simple groups. The most important two groups are fixed lens and interchangeable lens. The fixed lens cameras tend, with a few exceptions, to be smaller, lighter and more pocketable, therefore you are more likely to have it with you when you need it. Well that’s the theory anyway but I think we can say that you are more likely to be bothered to take it with you on that outing to the beach or the zoo.

However even with today’s zoom lenses, which are pretty wonderful, you will often find that you are too far away or too close to get the picture you want so you need to be able to change the lens for a longer telephoto or a wider angle. The other major advantage of these single lens reflex (SLR) cameras is that you are actually looking through the lens instead of a separate viewfinder so what you see is what you get, although this is less of an issue now that we can review our photos on the screen of the digital camera. The down side of these SLR cameras is that you very soon end up with quite a heavy bag of gadgets and are less likely to carry it everywhere with you. However much I yearn for a compact camera for it’s handyness I know I would be frustrated by it’s shortcomings so for me the choice is SLR every time.
