Am I in trouble
 

Last week there was a terrific program on the telly called, "Big Cat Diary". I was holding my camera when it came on and as an experiment I took some pictures. After the end I edited the pictures on my computer and was delighted with the results. Over the week I took more pictures each time the program came on and now I have a wonderful collection of "Big Cat Pictures". Now I am worried whether I will be in trouble for taking those pictures, am I in breach of copyrights. The pictures are just for my own pleasure, not in any way for financial gain. Here are some examples of my efforts.
Tanny.

You can see the pixels of the tele screen itself so there is no danger of them being passed off as original shots, just enjoy them.

Like what has been said above, aslong as you do not publish them or sell them, then you will be fine. - Would make a good wallpaper for your PC!

Thanks for the advice guys and I have to say that I am planning to use some of the pictures for paintings, I always fancied doing paintings like David Shepherd.
Now all of you have given me excellent and obvious advice but do you base this advice on the true letter of the law. I ask this in the event of someone else copying my idea and receiving monetery gain through selling their pictures.
At the age of 69 and only on the basic pension, I am unable to afford going to places I see on the telly to take pictures, so this new idea of mine has opened up a vast new interest, and stimulates my mind. When a bloke reaches my age he has to have plenty of stimulation, otherwise he just stagnates and starts, "Waiting for God".
I change my wallpaper at least once a week, Daniel, depending on the quality of the photographs I take each day.

Tanny,it will be very long time before you "stagnate!!!!!".

A single frame screen capture of a TV or film is normally, but not always, considered 'fair use' or 'fair dealing' under copyright law, as it is considered a small part (1/25th sec) of the over all work ('de minimus'). It is generally thought though that if you add some commentary or criticism along with your usage then you are on more solid ground, and if your usage is transformative (does not serve the same purpose as the original) then your position is even more secure.

Technically your are breaching the copyright. But as it is such a grey area and with the costs involved it is very unlike that anybody will pursue you over the matter. On the other hand if they thought they were losing millions of pounds through this sort of activity they would be after you like a blood hound. Principally the copyright law is about protecting the originators income.

Not quite. It can also be used to protect an originators reputation and other interests. This is a recent judgment on the issue by the US Court of Appeals as far as Open Source, Creative Commons, and Artistic Licenses are concerned:
