What you are looking for is a ND (Neutral Density) filter. To illustrate, here is an example of photo taken in daylight in a street with a ND1000 filter. The filter allowed a shutter speed of 6 seconds. With no filter, with the same aperture and ISO, the shutter speed would have been approximately 6/1000 = 0.006 secondes (no "ghosts" effect). Contrary to ...

Apart from using an ND filter, you might be able to achieve the desired effect by taking multiple photos and then blending them in post processing. Either an automatic blend with "ghost removal" might work, or layering the images and manually masking/unmasking selectively (in effect "painting out" the people). All of this pretty much requires a tripod for ...

Just to add a bit of links to the other (good) answers, if you do not want to use a ND filter, you can use multiple exposure and use an averaging method to simulate a long exposure --- basically, 20 exposures at 1/10 of seconds will be more or less equivalent to a 2 seconds exposures, or use a median filter, which can even be better --- in the right ...

Yes, this is generally the case. If you fix a value like aperture (which is what you are doing when you set the camera to Av mode), one of the other exposure factors must change — and the only other options are shutter speed and ISO. If you are using automatic ISO, that may or may not change first, according to your specific camera's program line. If you ...

As mentioned in Oliver's answer, you can use a neutral density filter, this let's through only a small fraction of the light, but it doesn't affect the color. You can then shoot at large aperture and yet have long exposure times. Another solution is to take many pictures and then use image stacking methods. This method can be used under favorable conditions ...

Yes. If you are in Aperture Priority mode, you are fixing the aperture where you want it and letting the camera decide the appropriate shutter speed. Thus, if you switch to +1 EC, the shutter will stay open longer.
