hi everyone,
Downloading various photo programs has been mentioned.But you should be able to find a computer magazine or camera magazine with an accompanying CD.
You can then download from a small choice [usually] If the magazine has the CD it will also have a few pages of
how to do it.
Read the magazine while you are in the shop, look at examples then decide if you are going to buy it or not.
Don't worry about making mistakes as there is an undo option.
