I have noticed in my holiday photos that there was some gunk showing up on the images, but before paying to have the sensor cleaned I wanted to figure out if it was on the lens or on the sensor.
So, I took some test shots of bright blue sky, with two different lenses, and I think the results are pretty obvious.
Gross. Off to get that sensor cleaned. I have been recommended to a place in London that does the cleaning on a walk-in basis. I’ll let you know how it goes, and will post a link if I’m happy with the service.
Now to find a photoshop wiz to fix the photos from Greece and Italy:-)
