Cleaning the image sensor.
If you’ve got a DSLR you’ve probably had the experience of uploading your photos onto your computer after a long day of photography – only to find that there are dark ‘spots’ and ‘blotches’ on your pictures.
These spots and blotches appear on all your shots in exactly the same position. They might be less noticeable on backgrounds with lots of detail (and more noticeable on plain backgrounds (like blue skies – especially when you have a small aperture) – but they’re there in all your shots (the picture to the left is one of the worst examples I’ve seen – and was the result of poor image sensor cleaning technique).

Most DSLR owners do eventually get some on your sensor (unless you never change your lens) but here are some tips for decreasing the likelihood of it:

If you still need to clean it further I suggest you bring the camera to a professional camera store for cleaning the image sensor and have the pros do it. They have all the equipment and frequently will do this within minutes and sometimes will not even charge you. In Austin I go to Precision Camera Most larger towns will have a store that can help you.
