Photographic Dust and Exposure

I often notice critical comments about dust in photos and the clone
removal methods. I want to spend this time correcting fools:
not all whitish specs are dust on the lens. Sometimes small insects
will fly into the frame as you press the shutter. Good bokeh will
turn the little insect into a spec if the shutter speed is high enough
to fully blur the insect. You don't have to remove these specs if
you don't want to do so. I often leave them in the photo because it
is a natural occurrence.
I've actually had dust on my lens and I can tell you that a decent
lens will make it appear more like a clear circular sticker.




Exposure can be confusing to new photographers. However, I find that
alot of so-called pros are still learning the subject.

I have seen many overexposed photos made by people claiming to be pros.
If you look at their images, then you can clearly see that the highlights
are blown. Bird photographers do this more often than other photographers.
If the bird is dark but the background is bright, then the bird is
underexposed and the background is overexposed. The photo is not good
enough for usage. Often times the photographer is using spot metering
but they missed the spot with medium light. Other times, the overexposed
photos are the result of a burst mode that wasn't properly exposed to
begin with. I have included two photos of mine which should help you to
see the difference between perfect exposure and overexposure.
