As stated above, there is something wrong with my camera. But I don't know whats the problem. There seem to be a 'dust' or 'UFO' in my pictures because the speck appears randomly. Pictures are needed to help some of you understand, so here you go.
[Sorry for the lousy photos. Still in the process of growing from a baby photographer to a toddler one ]
#1. This is the first picture I encountered this dust in my photo. Look at the right hand side of the picture. There seem to be this line curving downwards.
D70s + Kit lens
Some of you might think it is a bird or something flying pass, but how can that be, since the exposure was f22 at 20 seconds :/ Wouldn't the flying subject be blurred?
At first I thought it was nothing because my other pictures taken with the D70s and kit lens on the actual day with NO removal of the lens at all, the 'dust' did not appear.
No 'dust' in the photo
