How to check for sensor stains?
Slightly misleading title as I wasn't sure how to word it! Checking my Italian photos I can see a number of small sensor stains, particularly against the very blue skies. I thought I had dealt with these before I left, but obviously UK skies weren't blue enough.... I've cleaned the sensor, but...

Sticky pollen?

Sticky pollen? No - my nose attracts all the pollen from a 3 mile radius during the hayfever season:(

How to check for sensor stains?
Do you have any plain pastel-coloured walls in your house? If so, try taking a shot of a plain section of the wall that is evenly-lit and coloured. Either that, or turn on your a/v channel on your tv. Most of the newer screens will display a plain blue background. Whilst not ideal, it may be adequat...

If you post an Italian picture here the experts in sensor stains and crud, and the difference between the two, can probably tell you straight away which you have.

Italian picture as requested - embarassed to post it really! It's the one that shows the stains the worst - there might be some lower down, but I can't see them.

OK that is not staining - that is crud. You need to clean your sensor ;).

Thanks - not sure 'crud' is any more reassuring :) I've cleaned the sensor, but still struggling to test the image. Probably have to wait for a blue sky - that will be next June then....

I agree with Gwyn, they look like dust spots to me. They always show up more against the sky. Sensor cleaning time or spot removal tool:D

How to check for sensor stains?
I take my hobby VERY seriously :) I've cleaned the sensor and it looks spotless. When I do the dust check it's completely white, but I still have a few spots on the photos. Could it be anything else? It's the same on both of my PKA lenses so can't be the lens. Could it be dust on the mirror?

I've cleaned the sensor and .... You haven't said how. To be honest, whatever you're using isn't very effective. ...it looks spotless. 'Looks'? How are you judging it to be clean, since it very obviously isn't? :) Could it be anything else? No. It's ordinary specks of crap on the sensor. ...

Well thanks, I think. I'm not sure your reply needed to be quite so patronising. I'm judging it to be clean because the sensor dust check doesn't show anything. I've been around long enough to take that sort of reply with a pinch of salt, but I doubt a new member would come back again.

milamber, I have experienced the dust check showing it to be clear but there still be stuff on the sensor. I use an Arctic Butterfly brush, and now also have their loupe to check the sensor is clean. I don't know what you used, but I would try cleaning it again, maybe with wet swabs if you have ...

Well thanks, I think. I'm not sure your reply needed to be quite so patronising. I don't know why some people are simply determined to take things in the worst possible way. I wasn't at all intending to patronise. I just pointed out that whatever you're using, and however you're judging 'clean',...

I was going to link to the ones SRS sell, but their website seems to be down. :( Visible Dust, the makers of the Butterfly, do good swabs, but Eclipse are also good. Just check the liquid provided is right for the sensor.

Thanks again Gwyn I tried SRS too with the same result, so I've gone for the Eclipse ones. Fingers crossed!

What ND filters and vignetting risk
Having had firstly Cokin, then Hitech & now Lee I can honestly say Lee are worth it, even though they do seem rather expensive. Hard NDgrads should be fine in almost all situations, on cropped sensor cameras the graduation line isn't nearly as obvious as you might think, it's only really that ev...
