CUSTOM SETTING MENU You will use these menu banks when you get to the stage of wanting to fine-tune your camera settings to suit you personally and to exploit the full potential of your camera.
PLAYBACK MENU These are all the tools that are concerned with the viewing and management of pictures already shot and recorded on your memory card.
RETOUCH MENU With this menu, which is only available on some cameras, you can work on the image and make a copy while keeping the original untouched. This means you can print straight from your camera or card without needing a computer.
Factory presets
• Don’t let all the features worry you – the factory has preset your DSLR to basic settings that will get you started. You will be able to begin shooting as soon as you have charged the battery. Having got the feel of the camera, you can then get down to setting up preferences in the menus as you work your way through the book.
Exposure modes
Although the majority of cameras have a dial with which you set the exposure mode, some of them incorporate this function in the menu instead. Nevertheless, they all offer you the same choices regarding the type of exposure. These are aperture priority, shutter priority, program mode and manual mode.
Holding the camera
• Place one foot half a step in front of the other to maintain good balance. Hold the camera in your right hand with your fingers wrapped around the handgrip. Support the camera with your left hand under the lens. Keep your elbows pressed lightly to your body.
Preset modes
Your DSLR camera is a sophisticated computer and the preset programs are the result of an enormous amount of information that has been programmed into it. These preset modes set up the camera functions to match the subject you have selected, choosing combinations of shutter speed, aperture, flash, colour balance and focus that the camera decides is ideal for each subject.
Preset modes are very useful when you are starting but you can’t override the automatics. As your knowledge increases you will probably find this very limiting in creative terms and will want to move on to taking your own decisions.
Quick tip
• It’s all too easy to get carried away and forget to change your preset modes. Always check that you are on the right one for the subject you are shooting or the settings will be unsuitable.
Playback
The ability to see a picture as soon as you have taken it rather than waiting for negatives and prints to come back from a processing lab is one of the most attractive features of digital photography – particularly when you are shooting one-off events such as weddings or competitive sports.
The playback button
This button gives you access to the pictures that are recorded on your card. When you push it, the last picture taken will appear on the monitor.

Image information
By using the multi selector, you can gain a lot of information from playback. All the technical data about the images is recorded and will stay attached to the pictures when they are transferred to the computer – exposure mode, aperture, shutter speed, ISO, exposure compensation, date and time of the exposure, focal length of the lens, flash mode used, white balance setting and histogram.
Image information
Viewing multi images
Viewing multi images
This is the digital equivalent of contact sheets or thumbnails. You can bring four or nine pictures up on the monitor for review, depending on your camera model.
Close up
You can zoom into close up on a portion of the picture in stages using the +magnifier button, and likewise zoom out with the – magnifier button. Using the multi selector, you can also manoeuvre the magnified section of the image around the monitor to check details of your picture for sharpness and colour.
The histogram display
This is a graphic representation of the image exposure; the left side of the graph represents the shadow areas of the image and the right side the highlights. If the peak of the graph is over to the left the image will be underexposed and if it is on the right it will be overexposed. When the peak is in the centre it represents a normal exposure. This graph can be a bit confusing, but it’s not something to worry about until you become more experienced.
A problem with digital photography is that it’s hard to retain detail in extreme highlights. The histogram is useful to check this. If the graph runs into the right edge of the box (below centre) you’ll be losing highlight detail, so you’ll need to reduce the exposure.
Protecting images from deletion
Use this button to mark individual images so that they are safely protected from accidental deletion.

Deleting individual images
To delete an unwanted photograph from your memory card, press the delete button. You’ll need to confirm this with a second press of the button, or with a different one, depending on your camera.
