Two articles on photographers rights well worth reading, not sure how relevant they are in Ireland though.

1. Almost anything you can see you can photograph.
If you can see it, you can take a picture of it. If you are standing on public property you can photograph anything you like, including private property. It is important to realize that taking a picture is different than publishing a photo, which leads to point number two.
2. As long as you are not invading someone’s privacy, you can publish their photo without permission.
You can take someone’s picture in any public setting and publish it without consequence (even if it portrays the person in a negative way) as long as the photo isn’t “highly offensive to a reasonable person” and “is not of legitimate concern to the public.” You can even publish photos if you took them on private property. While you may be punished for being on private property, there is no legal reason why you can’t publish the photo from prison!
3. As long as you aren’t using someone’s likeness for a purely commercial purpose, you have the right to publish the photo.
You can use your photos of other people without their permission for an artistic or news purpose, but you can’t use them for a commercial purpose (such as an ad). You could sell a photo of a person without their permission, but you couldn’t use the photo in an ad saying the person endorses your product.
