Hi Jake,
could you elaborate a little on the above for the uneducated like me, if you don't mind? I use the above techniques for a large proportion of my shots and never considered them leaving me more vulnerable to dust on the sensor. Is it a heat thing attracting more dust?
i suppose I'm being a bit of a lazy ass and could google but I'd like to hear your take on it if you don't mind.
adox66, it appears @BackdoorHippie was in a discussion with Marcel about the same time you posted so I'm wondering if he missed your post. I do know the notification for quotes isn't working all that well. It will display a notification, but the particular quote that goes with the notification doesn't seem to show up until much later.
In any case, I can't speak for Jake, but when using Live View, the mirror is up for such a long time which exposes the sensor to any contaminates that may be floating around inside your camera. I have noticed my sensor shows more spots after using Live View even though I try to be careful when changing lenses. I'll be interested in Jake's thoughts on this as well.

Sorry I missed the post, adox66. What hark said. LiveView opens up the tube between your lens and your sensor with nothing standing in the way of any of the contaminants that were once in front of the mirror from now being directed to the sensor, and this time with the help of motion and gravity as you move around. So, in the spring, while you're laying on the ground trying to get that impossible up-angled photograph of all those flowers that you could never possibly see through the viewfinder, know that gravity is working hard along with the pollen in the air to dirty that sensor up.
That's not to say that you shouldn't do it. It's just a reminder that we do lots of things with our cameras that we'd consider normal and proper use that expose the sensors to all sorts of contaminants that we then want to think are a problem with the camera, because we're always so careful when changing lenses.

Not only is the sensor exposed, it's working and there is a lot of static electricity in there which WILL attract every particle of dust inside. I think that people using more "Live View" expose their sensors to more dust gathering.
I had the same problem. after about 1k shots I noticed an obvious spot on my sensor. I went to the menu / set up/ clean image sensor and hit the ok button. After that the "spot" on my d7100 went away.
Any body know if thats normal? Also I had someone tell me I had dust spots of my sensor but I have not noticed them. other than the obvious way how do I check for dust spots?

Yes, dust is normal. There's an entire industry devoted to helping the homeowner remove it, so it's inevitable that it's going to sneak into a camera on occasion, even if you barely, if ever, change the lens.
To check, place a plain piece of white printer paper on a brightly lit area. Set your camera on Aperture priority and set the lens to the smallest aperture available (usually f/16 to f/32). Switch the lens/camera to manual focus and turn the focus ring to the minimum focus setting. Take a picture of the paper making sure that if fills the frame and is fully lit (i.e. don't stick the camera between the light source and the paper). The combination of minimum focus and aperture will give you the clearest view of any dust on the sensor stack.
Many people recommend shooting at a bright sky instead. My take on this is that by shooting straight up you're inviting more dust onto the sensor thanks to our friend gravity. When you store your camera, store it in an orientation that promotes gravity moving dust away from the sensor and not towards it. At worst, store it with the sensor perpendicular to the ground. If possible, store it face down in your bag, or at least leaning downward. Dust that might normally be blown off the sensor may decide to adhere to it after prolonged contact, so keep it away as long as possible.

I also read that in addition to pollen, etc., the dust could actually adhere to the surface of the sensor depending on what type of contamenant the dust is, which will negate any benefits of using the sensor cleaning program built into the camera. Then, the only way you can clean the sensor is by manually wet cleaning the sensor. I highly recommend a Delkin Sensor Scope to be able to see your results from cleaning.
