I had been sending my camera for CCD cleaning since I started digital photography. Since my Camera is more than 1 year , had decided to DIY myself from now onwards. Thus got the Sensor Swab and the Eclipse soltuion from CP.
This is my first time DIY, would like to share how I test the CCD. Any comments are welcome
I am using 100-400 IS L USM, mount to the tripod with cable relase set to aperture f40 for image testing.
Need to off IS on lens or else will get blur image due to the IS movement
01) With IS on , image blur
02) With IS off, aperture f40. Can notice many dirts and some old scatches on the CCD
03) Using the Photoshop "Equalize" feature to see those hidden dirts
