This mode uses a longer shutter speed so may require
the use of a tripod or stand of some kind to help keep
the camera still enough to get a clear picture. If you have
the camera too close to the subject it may struggle to
focus. Try taking a photo from further away, if necessary
the image can be cropped later to enlarge the area you
want to show. Starting out with a larger image and then
cropping it will help maintain the details.
2. What resolution does the image need to be to be
suitable for printing? Is there a minimum/maximum file
size or specific file type that the publisher can use?
The resolution of an image refers to the image quality.
The resolution is measured in dpi (dots per inch, or the
number of pixels per inch). Ideally the image should be
a resolution of 300dpi or higher for printing.
Editor’s Note. Photos for the Journal need to be 300dpi
Before taking your photo check the settings in your
camera to make sure they are set at the right resolution,
also check the image quality is set to high or medium
(low will give a poor quality image).
File types – there are a number of different file types
that can be used for images, most cameras will have
the option of saving images as one or more file types;-
JPEG files tend to be used most commonly as they are
a more compact file so require less memory space,
however due to the way they reduce the file size some
of the detail in the image may be lost. This is worth
considering especially if you need to edit the image later.
Each time you save a copy more detail may be lost.
Raw files are the equivalent of the negative that you
would get from a film camera. This file type stores a
lot more information about the image so allows more
options when it comes to editing. However due to the
amount of information that is stored these files take
up a lot more memory space. These files need to be
processed or developed by a data convertor or other
compatible software.
TIFF files are similar to Raw files in that they store a lot
of information however they are easier to process as
they don’t require specific software.
3. How do you find out what resolution your image is?
To check a photo’s resolution on a Windows PC, select
the file you want to use. Right click on the image and
then select properties.
A window will appear with the image’s details. Go to the
Details tab to see the image’s dimensions and resolution.
4. Is the subject likely to move or do you need to get a
close-up image to show the finer details?

Figure 1. Under exposed/too dark – use extra lights if
available or a longer exposure setting as long as the
subject is not moving.
this can be useful when taking shots of subjects that
may move. As explained earlier, due to the faster shutter
speed, sport mode can also help reduce blurring, due
to hand-shake; the increased shutter speed may mean
you need an additional light source to prevent the image
being too dark.
As mentioned before, if you need a more detailed image
of a subject that is not going to move, then try Macro or
close up mode. This mode uses a longer shutter speed so
may require the use of a tripod or stand of some kind to
help keep the camera still enough to get a clear picture.
5. Where are you going to be taking the photo? Is
the area/room well lit? If not do you have extra lights
available to help light the subject?
Figure 2. Over exposed/too bright – use a setting with
a faster shutter speed, or if possible reduce the amount
of light on the subject.
Figure 3. Correct exposure allowing all the details to be
seen clearly.
In addition to your computer’s built in photo editor there
are a number of computer programmes available online
to help make minor adjustments to photos such as
altering the lighting/colour, cropping the image so it just
shows required area. For example Fotor and Be funky.
These are free to use as long as you only need the basic
tools.
