If the dust is on the pentaprism (the inside of the viewfinder) there's no way it can show up in the picture. If the mirror slaps upward before taking the picture, this thing is not in way of the path from the lens to the sensor. To me the spots in your picture look like normal sensor dust.
(perhaps I am understanding your post wrongly and you do no not mean that part)
Anyway, there can be dust on the mirror or the pentaprism as well. You should beable to remove it with a rocket blower (or a microfibre cloth, if you can reach it).
What about small spots on the outside of the lens coating? I noticed small spots like that and they disappeared after I wipped off the lens spots which got on the lens before I stuck on the skylight filter.
I think it is more likely to occur with point and shoot cameras and when shooting at small aperture values and a wide focal length. In each of these cases, the Depth of Field is big, which means that dust on the lens can come within the area which is in focus, and hence it may show up.
On the other hand, if I shoot with my 50 f/1.8 I can hold a finger in front without it blocking the view (you will only see a darker region). Thus, here dust (being a lot smaller) would not be visible.
By the way, I really like your last HDR. Having the moon in the shot like that definitly makes it a winner.
Thats a good call Prospero. It seems to me I was shooting small aperture and wide focal length when the spots showed up. Thats when I noticed the spots on the lens coating. After I cleaned it up all was ok.
Cool buildings everyone...!!!
Here is one from me.
Aldor, nice colors, i wonder if you have more of the place?
Kardinal, your shot left me impressed. Sometimes a photographer makes otherwise dull building look so interesting. Great work, using B&W was an excellent idea.
Thank you Ginteras.
First post in this forum, hope this turns out..
This was taken a few months back in Niagara Falls, Ont.
Its definitly not one of my best pictures, But I thought the building was pretty cool looking.
It hasnt been altered in any way.
I am sure it can use some photoshopping to touch it up a bit. BUT.. I'm not 100% familiar with it.. if anyone wants to do it and post it back up.. be my guest. haha.. I can send the original file if you like.
Judging by the color of the car the picture isnt bad overall. There isnt much to 'fix' in it with photoshop.
