For my camera, it lists the true megapixel number as the same as the actual megapixel number, so I don't think we should make too much of this number. The site also lists sensor size and pixel size. You can calculate the pixel size also by dividing the sensor area by the megapixel number. If you tak the square root of this number, you get the pixel size as ...

Simply you can process a 4mp image using photoshop and upscale it to 8mp image. Then there will be duplicated pixels , but theoretically it's an 8mp image now. I believe snapsort's "true resolution" means an image's actual pixel resolution without having such duplicated pixels.

A lot of the other answers made this unnecessarily complex and talked about things irrelevant to the OP, so let me try to be clearer: Many people think that a higher megapixel camera produces sharper photos. However, for a given sensor size, there's a limit on how many megapixels of actual information can be captured. Exceeding that limit doesn't help. If ...

No, digital exposure is the same, the shutter is opened for a length of time and the sensor records whatever light strikes its surface over that time, just like film. There is some technical information here: What is the structure of a photosite? One difference between digital and film is that digital doesn't suffer from reciprocity failure.

Perhaps one should mention that Ansel Adams shot his famous image "Moonrise, Hernandez" with an 8x10 camera (i.e., the film size was 8"x10", and the crop factor would be 0.14x). Now, granted, a view camera allows lens/film movement (tilt) so you can also use the Scheimpflug principal to increase the DoF, but generally speaking, no, shooting any currently ...

Landscape photography typically uses apertures at the sweet spot of the lens' sharpness which are usually narrow enough to allow for large Depth of Field(DoF), yet still wide enough to avoid problems with diffraction. Remember that the larger the pixel size of a sensor is, the narrower the Diffraction Limited Aperture will be. My 18MP APS-C camera has a DLA ...

No, this isn't a huge deal. Aside from the 1x00D series, other Canon camera models that did not have the sensor-shake/cleaning feature include: 1Ds, 1DsMkII, 1D, 1DMkII, 5D (classic), 10D, 20D, 30D, 300D (Rebel), and 350D (XT). I shot with the 350D (it was my first dSLR) for four years, I changed lenses like a mad thing, often forgetting (gasp! horror!) to ...
