Exposed – The Dust on my Sensor

Today I decided to tackle my “image rejection” problem head on. I researched a little further with regard to having dust spots and blemishes on my images; this was the main reason for my images being rejected.

Today I decided to tackle my “image rejection” problem head on. I researched a little further with regard to having dust spots and blemishes on my images; this was the main reason for my images being rejected.

Based on my findings, thanks to my tutor pointing me in the right direction and also to BOB – thanks BOB – the best way to check your sensor is as follows:-

  • Take an image of a white or grey card using as high an aperture as your lens will allow (f22 or higher)
  • Over expose it by a couple of stops
  • Increase the contrast in an image editing programme as above
  • Change your lens and follow the same procedure once more
  • then shed some tears when you see all the tiny black spots appearing in the same place in both images – these are the dust or dirt on your sensor !

I shall sleep on my decision as to what to do next! I have ordered a cleaning kit from Morris Photo – my favourite supplier, hint, hint! BUT, I certainly am not ready to attempt the cleaning of the sensor myself and John does not come home from sea for four weeks. Dilemma – do I trouble someone else – I just think I might! with a big “please” to our college technician, another John.        ONLINE LIBRARY
