Photograpghy Quick Tips
Quick tips as they come.
- Exposure Value - Your Exposure Value (EV) switch is the quickest way to adjust the exposure of an image. Usually a switch with the symbols [-/+]. This works in automatic mode and will change the aperture [-] by half the current value or [+] double the aperture size quickly. If you are taking a picture of a bright scene and you suspect that highlights may be burned out, reduce the aperture value by pressing the [-] button one or twice. It is generally better to lose shadow details rather that highlights in a shot.
- Anti Shake compensation - If you are buying a new camera and you intend that you will be taking low light or indoor pictures, look for a model that has a version of shake compensation. If you ever find you are taking pictures that are blurry, the chances are that this is due to camera shake. In low light the shutter may be set low to allow enough light in to expose the scene correctly. It is very difficult to avoid camera shake when the shutter speeds fall below about 1/60th of a second. Traditionally a tripod or other support is necessary for these situations. Using shake compensation the image is electronically stabilization to enable you to get a clear shot in low light situations.
Both of these compact or consumer cameras have anti shake technology built in. As you can see this technology is available at all prices ranges

Why you should keep those fuzzy or out of focus pictures.
Your photography should be about enjoyment and fun.
If you are getting frustrated about pictures not turning out the way you'd like, you should perhaps relax about things and try to do your photography when the mood takes you or when you feel inspired.
Just because you had taken a trip to Udaipur, it does not mean you have to have brilliant images to bring home.
But photography is about taking pictures, and you should consider each shot an experiment.
Once learn you to use the histograms (see my blog on adjusting colour levels) to spot problem areas in your images, you will quickly learn how to correct blown out highlights and deep shadow areas.
If you are not happy with an image you can of course try again in many circumstances, electronic memory is a powerful and cheap media for experimentation.
In fact it is such a cheap medium that it allows you to keep shots that you may want to delete. One reason that you may keep a “bad shot" is that technology is improving all the time, and soon you may find that software is available that will allow you to completely recover the detail in an image.
The reason I want to discuss is that you can easily reuse images.
Here is a reused image that I used to create a background for an ebook.
This image was cut from a really bad photograph taken in the dark at a Water show in Parc d'exploration, Futuroscope, Poitiers, France.
I'm not sure why I was trying to take pictures way beyond the capability of my camera at the time though.
But this image could not be easily produced by design.
Here is one of my favourate rescued images and one of my favorite images anyway.
This picture is of the nave at St Davids Chapel, Pembrokeshire, Wales.
I tried to take a low light shot requiring a 4 second exposure. Try as I might I could not find a suitable support for my camera so I tried to stand "sniper" still holding my camera and failed miserably. Later however I notice that this picture was ideal for reuse using the GIMPs artistic filters, in this case one called oilify.
This has changed a picture I would have deleted into one that has sold on the Internet and I am quite pleased with.
I have come to like the idea of creating oil painting from digital images.

Color levels adjustments to your images.
Using software to make basic adjustments to your photos.
I originally wrote this article for a friend. I hope it is useful for others too.
The difference between the image your camera captures and the image you wanted can be affected by many things. One of the most important things to remember is that your camera is a mechanical device (in an electronic way of course) and your are an emotional creature (in biological way, naturally).
A camera image is a collection of information about the scene that when viewed is arranged in a way we recognise as an image. The information that is captured is a digital representation of the subject.
Your camera will probably have a display mode that can tell you about the data it has captured for an image.
One of the simplest and most useful is a colour distribution histogram.
Here is an example of a picture along with it's colour distribution histogram.
In this example we use the sliders beneath the histgram to enhance this image.
NB. How one views a picture (or which one perfers) is a subjective matter. These are to illustrate how dramatic changes can be made just by adjusting the histogram distribution.
Basic colour distribution histogram.
To illustrate how the stacking of the colours shown in the histogram works, I have taken two pictures of my power ball (below) one on a dark background and one on a light background.
Notice that in the first Picture the histogram shows that largest concentration of pixels are to the left of the histogram and in the picture with the light back ground most of the pixel stack up more to the right representing more dark pixels.
NB. Notice where the stack of pixels are so tall that they go vertically off the scale. This tells us that details in that portion of the picture is greater than 255. 255 is the maximum value of a colour that can be stored, the value represents pure white. The fact these values go so abruptly of the scale, shows that those pixels are over exposed and the missing detail is assuned to be 255.
An example showing adjustment using the level command.
In this picture of this Catherdal in Poland, the white of the building has caused the sky to become over exposed making the sky a much paler blue than I remember it.
For this example I have use the donation-ware software, GIMP (GNU image manipulation program) to make slight changes to bring back the deep blue sky colour and introduce more contrast into the images
I have opened this picture in the GIMP and selected Colour / thresholds to bring up the simple histogram that shows the spread of colour values across the picture.
There are three tiny triangles beneath the graph.
The left most arrow is the extent of details captured in the dark range, the middle is the midpoint a kind of relative “white” from which the other colours in the picture are calculated. And the right side is the extent of detail captured in the “light” side of the graph.
By moving the tiny (just the left and right triangles for now – the mid point will automatically adjust.) triangles to a point on the histogram where the histogram values start proper, we effectively compress the spread of values through the picture which gives deeper blues.
Notice that in the “before” picture above the range of values across which the colours are spread are 0 on the left and 255 on the right.
After moving the triangles until the left value is 39 and the right is 242 we have effectively compressed the colours, this has restored the blue sky and allow the clouds to be more defined.
Below you can see the effect of the adjustments made represented by the values on the histogram below A and B.

(this can usually be found by pressing the button for playback, then the display mode button one or more times).

The histogram can help you adjust the color level of you images at shoot time and afterwards on a computer with an advanced graphics editing program.
(In this brief example I use donation-ware software called the GIMP - GNU image manipulation program).
On the histogram the leftmost horizontal value represents a value of 0 and increments to the right most side with a maximum value of 255. Vertically, the values start at the bottom line with a value of 0 and extends to the top with a value of 255.

- Use your cameras histogram display regularly to check the colour distribution across the graph.
- Also check for blown out details, values that are shown going abruptly off the scale. These represent lost detail that currently cannot be easily recovered.
- As long as the details exist in the image you can use software like the gimp or Photo Shop to enhance your images.
- Experiment with levels in your digital dark room to see the dramatic changes this tool can make to your images.
