Cleaning photos of the Roman amphitheatre / Coliseum at El Jem, Tunisia

I’m still cleaning up my photos for library submission.  Now, I’m ware I’ve been saying that for a very long time, and I’m sure people are begining to wonder why it is taking so long.

Take a look at today’s photo – it is of El Jem in Tunisia.  This is one of the photos I cleaned up today.  Now take a look at the magnified sections.  Look at the before image and you will see lots of black dots on the image.  This is caused by dust on the sensor.  Every single dot has to be removed from the image – it is a time consuming, pain staking process.

Why so much dust on the sensor?  Well firstly Tunisia is a dustly place.  Secondly I had just purchased the camera (a Canon 5D) shortly before going on the trip.  I didn’t know it at the time but the 5D has something of a reputation as a dust magnet.  And thirdly at the time my sensor cleaning kit involved the use of flamable chemicals so I couldn’t take it on flights and it had to be left at home.  So the only thing I could do was to digitally clean about 400-500 Tunisian photos on my return. And that is why it is taking so long!
