Keep in mind that if the area around the sensor is dirty, using the blower bulb can make it dirty again. If the shutter is closed, wrap some tape around your finger so that the sticky side is out and use that to run around the sides of the inside of the camera in front of the sensor. If there's some felt-like flocking in there, don't press hard on it. If there's a mirror, make sure it is in the up position. Then use the blower again.
After that, just use the blower occasionally. You'll always see spots when using a pinhole. The Spot Heal Tool in Photoshop or similar tool in other image editing programs is a must.
PROTIP: once you have a sensor cleaning wand/squeegee you can cut up new microfiber cloths to fit around the head of the cleaner so you can reuse 1 stick forever. Just replace the piece of cloth after every use. Watch this video and others before trying to clean your own sensor:

The shorter the focal length of the pinhole the brighter it will be. Longer focal lengths, even those with much larger pinholes, are much dimmer to the point where sometimes you can't see anything even with the screen.
FYI, pinholes don't have an infinite range for their DOF. It actually starts about 1-2 feet in front of the camera to infinity, depending on focal length.. So, don't get too close.
>>3360215Don't do the shower thing. Just use your breath instead. That is more than enough moisture to loosen stuck pieces. Having high humidity with cameras is a bad thing if they are not properly sealed and having the lens off and sensor exposed means they are not properly sealed.
